About Aragon Watch:
Aragon is a rebranding by OKO International in 2015 of what had been their Android brand of watches, founded in 1991 by Wing Liang. The trademarking of "Android" by both Wing (OKO Int'l) and Google wasn't a problem for some years as Wing made watches and Google made an operating system for cell phones. It's not that uncommon for a name to have multiple trademark holders so long as they're in different business and product sectors that prevents public confusion about who the trademark represents. The problem arose when electronics firms began designing and making "smart watches" using and/or interfacing with Google's Android O/S. Now both companies were in the business of watchmaking and both using "Android" related to watches would not work. The pragmatic solution for Wing was reaching an agreement with Google (et alia) and rebranding his watch line with a new name, Aragon. If there seems to be a strong resemblance in style between Android and Aragon watches, they have the same designer, Wing Liang. The Divemaster Automatic is one of six models that launched his new brand name in December 2015.

The 30.5mm diameter dial is a single layer with ultra-fine sunburst pattern radiating from its center. It's plenty large enough to see well without impinging on the width of the rotating dive timing bezel. The Aragon name and other labeling, along with the minute track is printed on it. A nice frame surrounds the day and date window. The broad, bold baton and disc hour markers stand proud from the dial. The long polished broadsword minute hand is beveled slightly which aids in maintaining visibility under different lighting directions. The bold and short arrowhead hour hand prevents any confusion between it and the minute hand, which is important for divers timing their dives. The central seconds hand is a fine pointer style in dark red, which provides significant color contrast to keep it from getting lost on the dial. Overall it has a simplicity that makes it very easy to read under all types of lighting without looking empty.

The 120-click rotating timing bezel in the same background color as the dial is smooth, firm and precise without any slop or lash, and it's unidirectional, as a dive timing bezel should be for safety reasons. It takes some definite torque to turn it, without any undue force required, which is also a Good Thing for divers. It's not going to accidentally get rotated very easily. The width of the bezel is in good proportion to the watch head and dial diameters, with nice bold, easy to read numbers and tick marks.

In a shade of blue slightly darker than the one commonly used in the Androids, the overall dial, hands and bezel design and layout get high marks for their unambiguous legibility.

The brushed finish bracelet has solid machined links, including the end links that attach to the watch head and integrate very smoothly with the lugs. Clasp is a signed double pushbutton Z-fold with a safety and three holes for micro-adjustment of the bracelet length. While it's not machined steel, the clasp is very heavy gauge sheet metal. It's not going to flex or bend, even with some harsh use. Closure is firm and solid, including the safety. Links are held together with industry standard "split pins" and the links have arrows on the backside showing the direction in which to remove them. At 4mm thick and 22mm wide without any taper, the bracelet has enough heft to counterbalance the watch head.

Movement under the dial is the SII NH36A, a caliber number SII and TMI use instead of the 4R36A caliber number Seiko Watch Company uses when they put the same movement inside Seiko branded watches. This 24 jewel, 21.6 kbph mid-beat is an evolution of the 23j 7S36, that includes hand-wind and hacking capability, and has the same ~42 hour power reserve with full wind. Even though the NH36A/4R36A is a relatively new movement, its design is based on a very mature and proven workhorse. In spite of the display back, it's undecorated, a "feature" that's pretty to look at and raises the manufacturing price of the movement (and hence, the watch), but doesn't contribute anything to reliability, durability, precision or accuracy. The one small nit I have with this watch is the Aragon logo and other data printed onto the display glass. Wing used to etch it into the steel frame around the display glass on the case back. Even though I used to sit and stare at the test pattern on TV as a young child (you have to be old enough to remember the test patterns - from when broadcast TV stations signed off the air at night for several hours), I don't stare at running watch movements, although a running balance is pleasing to watch for a short bit, so it's not anything significant. I did notice the back has holes for a case back wrench with round pins, and these are right in the middle of where the serial number and other watch data would be etched. The back wrench is less likely to slip out of these holes compared to the traditional shallow, rectangular edge notches found on most wristwatch backs. If that was the design trade-off, I'll go with the round pin holes for the case back wrench.

The Aragon logo in the signed screw-down crown is filled with red paint, a nice touch. The proportionally sized crown has good knurling with just a touch of radius added so that it doesn't feel jagged, allowing it to be screwed down, unscrewed and manipulated easily for winding and setting the watch, even with the ample crown guards around it. This is facilitated by the offset position of the crown relative to the crown guard. This offset allows it to be turned more easily and provides it with greater protection from above the watch, the most likely direction from which a blow to the crown would occur.

At 45mm diameter and 17mm thick, the watch head is not small, even though there are much larger watches now. It can still fit small wrists well in spite of its diameter with a 50mm lug-to-lug length that's not much longer than the main watch body diameter. The short lugs curve downward rapidly toward the wrist and away from the watch head, allowing the watch to wear "smaller" than its physical size. I have a 6-7/8 inch wrist (17.5 cm), which is not that large. This 45mm Divemaster fits on it quite easily without completely filling it, more easily than a couple slightly smaller diameter watches I have with longer, more horizontal lugs. It also fits under my dress shirt cuffs without any trouble, even with its 17mm height (your mileage may vary depending on how tight your shirt cuffs are).

Lume is very bright with excellent persistence. The bezel ring has a lume pip in the middle of its index wedge. The hour indices are filled with lume making them bold and very visible. Likewise, the centers of the hour and minute hands are filled with lume, making them bold as well. The hands are slightly brighter than the hour indices and bezel pip, making them stand out more and keeping them from being lost visually in the rest of the lume.

Even though it's rated to 200m, I strongly recommend having it depth tested by a competent watchmaker equipped to do so before using it for diving. After that it should depth tested at least every two years as long as it continues to be used for diving. This is a sound safety practice not just for this watch, but for all watches and dive computers regardless of brand, depth rating, or water resistance reputation, if they're being used for diving.

In summary, the Aragon 45mm Divemaster Automatic is an attractive watch that maintains the traditional diving tool watch style, elements and principles: bold and highly legible hands, indices and timing bezel markings. It's comfortable on the wrist, even a smaller wrist, in spite of its size and mass compared to many other watches. It's an excellent model in Wing's relaunch of his watch business under the new brand name. Divemaster is a very fitting model name as it shows Wing's mastery of dive watch design. It demonstrates a functional tool watch doesn't have to look like it's just a tool; it can also be visually very attractive with style and class.

Android Parma 9015 Automatic
Miyota 9015 28.8 kbph 24j Automatic

  • Reference #​: AD658BK
  • Diameter (W/O crown): 46mm
  • Dial Diameter: 35mm
  • Case Thickness: 13mm
  • Lug to Lug Length:55mm
  • Lug Width: 24mm
  • Weight (with all links): 280g
  • 316L Stainless Steel Case
  • Screw down case back with hardened mineral glass display window
  • Slightly domed hardened mineral glass crystal
  • Cyclops on underside of crystal over date window
  • 5mm thick 316L stainless steel bracelet with solid end links
  • Solid bracelet links with unique rectangular hole traversed by a steel dowel
  • Miyota caliber 9015: 24j 28.8kbph high-beat auto with quickset date, hand wind and hack
  • Miyota Parashock shock protection
  • Screw down crown with sunburst in lieu of Android logo
  • Water Resistance: 200m / 660 ft
  • Partially lumed skeleton broadsword hour and minute hands
  • Black mother of pearl dial with lumed hour indices

A brush finish case set off by a polished mirror finish bezel houses a Miyota 9015 high-beat movement. Its cushion shape makes the watch appear larger than its actual dimensions. Steep falloff of the lugs and end links allow it to fit smaller wrists.

The cyclops over the date window is on its underside, giving the date display greater legibility, and the very slightly domed crystal mitigates glare. The signed spiral knurled screw-down crown has plenty of grip without sharp or rough edges, extending sufficiently beyond the crown guards when unscrewed to be easily manipulated for winding, day/date quickset and time setting.

The Miyota movment's high beat rate is readily apparent in the smoother sweep of the second hand compared to mid-beat and standard beat movements. The movement is decorated with Geneva stripes on its bridges and a fine sunburst brush on its rotor. An idiosyncrasy of the Miyota 9015 is its unidirectional auto-wind. Most auto-wind movements are bidirectional which requires additional mechanics in the auto-winding mechanism (Seiko uses an eccentric wheel and a twin-pawl lever), but unidirectional aren't rare either. Miyota's auto-wind have remained unidirectional. The rotor only winds the movement in one direction and freewheels in the other. In a watch this massive it's very unlikely you'll ever feel or hear this (as some do with the ETA [Valjoux] 7750 chrono movement), nor should it make any difference in keeping the watch wound through normal wear, even office workers that work mostly at a desk. It does make a difference if you're using a watch winder, which will need to be set to wind (spin the watch) clockwise, the opposite of what you'd set it for to wind a Miyota 82XX series movement.

Each of the long and broad hour indices is filled with lume, the one at the three slightly smaller to accommodate the date window. The semi-skeleton hands are lumed at the tips and are slightly brighter, making them visually prominent among the bold hour indices.

The standout graphic design feature of this Parma 9015 is its black mother of pearl dial. Light plays off the dial with subtle metallic pastels in blue, green, pink and purple, constantly shifting as the lighting angle changes. Wing uses real mother of pearl, making each dial in the Parma 9015 MOP a subtle one-of-a-kind.

Ion Plating (IP):
Ion plating is a type of “Physical Vapor Deposition” (PVD) that specifically uses ionic bombardment during the coating deposition process to facilitate its bonding with the substrate, in this case the 316L stainless steel. PVD is a nebulous term as it generically encompasses several different deposition methods (e.g. sputtering and evaporation). IP is more specific about the coating process used. It’s also called “Ion Assisted Deposition” (IAD), or “Ion Vapor Deposition” (IVD). Ions are atoms that have had one or more of their electrons stripped from them to give them a non-neutral positive charge. These ions can be accelerated using electromagnetic fields to bombard the surface being coated while the coating is being applied. IP is a more specific description of the process but there are still many variables. The specific ions used in IP depend on the exact nature of the process, the substrate material being coated, and the coating material being deposited. They may be an inert gas, a reactive gas, or a component of the coating material. While IP is alleged to be more durable and wear resistant than a PVD that doesn’t employ ionic bombardment, much depends on the exact process used, how well it is designed for the substrate and coating, and how well it is controlled during the coating process. While some watch makers simply use the nebulous PVD to describe the coating, using IP is more specific but still ambiguous. One cannot draw too much inference from the use of PVD or IP to characterize a watch coating without more information regarding the exact process, coating material, and how well it’s controlled.

This is a military inspired design. Unlike a soldier’s “tool” watch, the tall cylindrical case with thin bezel and deep dial are of a style one would expect to find for a clock on a military ground vehicle’s instrument panel. This theme is carried through with the gun metal IP (on this variant), the stencil style Arabic hour indices, and a bracelet with center links inspired by tank track. There are no soft curved surfaces with wide radii other than the cylindrical case body and bezel. The wide lugs are angular and beveled. The overall effect is a chiseled, hard and strong industrial look, and it’s emphasized by a 325 gram mass. While the lug and bracelet design mitigate the large 49mm case diameter some, the 55mm lug-to-lug length and their shape are more important regarding how it will fit on smaller wrists. This Android is not quite as forgiving as some others in that regard. It’s at the very limit of what my modest 7” (18cm) wrist can handle.

Build execution is the excellent level typical of Android. Examination using 5X and 10X loupe magnifications, and the macro-photography, do not reveal any flaws or rough finish work.

Parts fit together with precision and the dial printing looks quite good. The watch head and bracelet have a good smooth feel on the wrist without hair pulling, or pinching. There is sufficient radiusing and beveling of edges and corners on the case and bracelet to prevent them from feeling as if they are cutting or digging into the skin.

The SII NH35 movement is identical to the Seiko 4R35. Why SII and Seiko use different caliber numbering for the same movements, built on the same production lines, baffles me. The only difference between them is the caliber marking on the movement. The NH3X mid-beat movement family is a step up in features from the NH2X family (aka Seiko 7S26/36) with the addition of hand-wind and hacking. It is proving to be as reliable a workhorse and is rapidly displacing the NH2X family. Even with a display back, Seiko doesn’t decorate their movements beyond a straight fine brush finish to the bridges. It’s as functional a finish as perlee or cotes de Geneve, just not as pretty looking. Under a loupe the machine work is precise and very clean looking, as are the parts edges. By comparison, I’ve looked at some Tianjin and Sea-Gull movements under 10x and at that magnification they are not nearly as refined looking as Seiko, Miyota, or the reputable Swiss movements ETA, Sellita and Soprod (never considered Claro Watch, S.A. reputable, but that’s a sordid tale for another time).

The standout feature of the Frontline is the military inspired graphic design of its case and dial, and a no frills, straightforward, purely functional aesthetic. There’s nothing exotic about the SII engine inside. It’s a reliable, durable, robust workhorse used in many different watches. For this specific variant, the gun metal IP adds character. I’m not as concerned with long term wear on the gun metal IP coating as I would be with other colors such as black or gold. Any eventual wear through revealing stainless steel on corners or along edges, would not have the high contrast of other colors, and would give some graceful aging to the finish (sometimes called “wabi,” a Japanese term describing visible aging as an aesthetic with its own beauty). The one drawback is lack of dial lume, in spite of the hands being quite bright and sufficient to tell time. On the other hand, the stencil styled Arabic hour indices and the dial’s subtle, very fine vertical brush finish have a no nonsense, purely functional appearance.

The end result is a very harmonious combination of dial, hands, case and bracelet in realizing the design concept, combined with a robust workhorse movement inside.

About Orient Watch Company:
Orient Watch Company was evolved out of Yoshida Watch Shop, a wholesale pocket watch dealer that opened in 1901, selling imported pocket watches. Yoshida began making gold watch cases in 1912, and expanded again into making gauges and table clocks under the name Toyo Tokei Manufacturing in 1920. They started making wrist watches in 1934. The economic aftermath of WWII resulted in Toyo Tokei going under and closing in 1949. It was reincarnated as Tama Keiki in 1950 using the former Toyo Tokei factory in Hino. A year later in 1951, the name was changed to Orient Watch Company, Ltd., and the first Orient Star was introduced, a tier above the standard Orient. The Royal Orient flagship line was introduced in 1960. Seiko-Epson (TYO symbol: EPSON) bought an interest in Orient in 2001. Epson gradually bought out the private shares held by family members and other long-time owners, eventually owning it outright in 2009. 
It’s important to note that Seiko does not own Orient, Seiko-Epson, aka “Epson,” (TYO symbol: EPSON) a very large holding corporation owns Orient Watch Company, Ltd. Seiko Holdings Group, a different very large holding corporation (TYO symbol: SEIKO), owns Seiko Watch Corporation. The two watch companies are entirely independent, with no common management up through and including their respective corporate boards of directors. Epson and Seiko have their own, different, public stock traded separately on the Tokyo Stock Exchange. Seiko “ownership” of Orient is frequently claimed and parroted all over the Internet, and it’s completely incorrect. The only connection between the two corporations: Suwa Seikosha started a subsidiary, Shinshu Seiki Co, to build precision parts for Seiko. Seiko needed an electronic printer for their timers at 1964 Tokyo Summer Olympics, and Shinshu Seiki made them for Seiko. Ultimately electronic printer modules became their core business culminating in EP-101, an electronic printer. Its successor, EP-Son, the son of EP, was concatenated into EPSON which became the subsidiary’s name in 1982. Suwa Seikosha and its subsidiary Epson merged in 1987 to form Seiko-Epson. There is substantial stock ownership in both corporations by members of the Hattori family, descendants of Seiko’s original founders, and various subsidiaries of each do business with each other.

The Constellation has a highly polished case in a standard round shape with a zero width bezel. The AR coated sapphire crystal covers the entire top, consuming 37mm of the 40mm case diameter. Lugs are also a standard shape flowing out from the case sides with gentle curves. The sides are slightly beveled which provides a softer appearance, avoiding a harsher cylinder shape straight vertical sides would have. Back is screw down with a full mineral glass display window that allows a complete view of the movement. The case, lugs and bracelet are understated, which allows the dial to dominate.

This Orient appears larger visually than its dimensions due to its zero width bezel, allowing a dial only 3mm smaller than the watch’s outer diameter. Dial color is a metallic slightly off-white, a little whiter than eggshell but not as stark white as a porcelain dial. Chapter ring contains the 24-hour markers with Arabics for the hours and tick marks at the half-hours. The main hour indices consist of 6-9-12 Romans with batons for the remaining hours. These applied on an outer ring with a texture of fine concentric circles. Small minute tick marks are at the outer edge between the hour markers. Inside this is a guilloche sunflower pattern covering the remaining inner part of the dial. Main hour and minute hands are narrow dauphine style with fine tips. Seconds hand is a fine narrow pointer. The 24-hour hand has a diamond shaped tip that easily differentiates it from the other hand. Highly polished silver, they’re readily visible against the dial. One important note is the lack of lume as this could be a deal breaker with some. There is none on the dial or the hands. Personally I don’t necessarily expect lume on a dress watch, which this clearly is.

The seven link wide bracelet has a nice combination of alternating fine brush and polished links, and it’s very flexible. The butterfly clasp is well hidden when closed giving a nearly unbroken continuous appearance. The links aren’t that long, which eliminates the need for half-links. Removable links are fastened together with standard “split pins” and the links have arrows on the underside showing the direction for removal (insert in opposite direction).

The 40P51 movement is among Orient’s newer ones that features hand wind and hacking. Like Seiko, Orient has been stepping up to adding these features in its newer movements, with a “trickle down” of features from their top tier Orient Star Royal through the Orient Star models and now into the upper price points of the main Orient tier. The lower price points are still using the workhorse 46XXX family of automatics which span a number of complications, but none of which have hand wind or hacking. Both Seiko (7S2X) and Orient (46XXX) have had a rationale for this related to marketing very inexpensive mechanicals with movements from these families to 3rd World countries in Asia and Africa.

Standout features are the Constellation’s spectacular guilloche dial and a true GMT auto movement with hand-wind and hacking underneath it. Add to it a sapphire crystal and a comfortable solid link bracelet (with SEL), and you have a real winner. This is an Orient Star quality watch with an Orient logo on the dial, and it’s at the top end of that tier. Why it’s not an Orient Star puzzles me some, but the Star line has two GMTs that I’m aware of using the same movement.

The Orient Constellation’s contemporary size, design elements and top end materials combine harmoniously to create a true GMT dress watch that is a sleeper at the top of the standard Orient line.

Orient ignored North America and its potential market for many decades, focusing on marketing domestically and with its lower lines elsewhere in Asia, with some presence in Western Europe. Their main products have been and continue to be mechanical with in-house movements. They have introduced some quartz models, but in small numbers compared to the rest of their collections. North Americans looking for Orient watches had to use Japan dealers directly, Rakuten Global, gray market storefronts and eBay, all via the Internet. There is a small official presence in North America now with one Internet based authorized distributor/dealer, but the many use the other sources. Orient now has four basic tiers:

  • The “Crystal” with three five pointed stars or an “AAA” on the dial are their lowest, basic economy line, targeted as affordable watches to economic regions with low GNP and incomes. They can be readily found on eBay.
  • The standard Orient bearing the corporate logo is a broad tier of price points, with variance based on materials such as sapphire vs mineral crystals, etc. There are a number of collections or categories in this tier. This Orient is at its very top end.
  • The third tier is the upscale Orient Star using an “S” inside an oval for its logo. Design, materials and build are generally a cut above the standard Orient line with a slight crossover from the top end Orients. Some Orient Star are Japan Domestic Market, and are not exported by Orient outside Japan. One can get the JDM models from Japan dealers and gray market, but it can take some searching. There are several collections that cover a variety of general styles within the tier from conservative to avant garde and edgy.
  • The flagship tier is the Royal Orient, a competitor with the Grand Seiko, commanding street prices in the Omega range. The Royal Orient have their own movement calibers, they are hand built in small numbers, and all are intended to be Japan Domestic Market.

I have no affiliation, association or financial interest with Orient Watch Company, its parent Epson, or any of their other subsidiaries, distributors or dealers.

Tissot produced their T-Trend Quadrato collection before the original August 2012 broadcast of Breaking Bad's season 5 episode 4 that featured the Tag Heuer Monaco and popularized square watches, particularly chronographs. While I don't have production dates, examples of the Quadrato automatic chronograph can be found on the Internet dating back to 2010. There's no doubt about its distant resemblance to the square (Tag) Heuer Monaco, although the Heuer is a two-eye with the minute and hour accumulators at the 3 and 9, plus the original Steve McQueen wore was a partial destro with the crown on the left and pushers on the right. (The Breaking Bad Monaco is a caliber 12 with the crown on the right.) While the Tissot Quadrato auto chrono has some resemblance, its dial graphics and sub-dial layout are unique enough to stand on their own. I don't know when the Quadrato collection was discontinued, but it was at least a year ago, if not two. NOS can still be found in the Internet storefronts of reputable watch dealers, although the scarcity of new ones is increasing.

The dial has considerable visual depth in layers. Four brushed silver bands extend the hour indices across the dial from 1-->7, 2-->8, 4-->10 and 5-->11. The minutes and hours totalizer sub-dials have gray rings with their index markings are overlaid on top of these bands, along with the seconds sub-dial and day/date window frame. Even the hour and minute hands have visual depth. A steeply beveled chapter ring enhances the visual effect.

A steeply beveled chapter ring enhances the visual effect, setting the dial well below the crystal giving the dial layers and hands plenty of head room. The gray totalizer rings with white indices enhance legibility. Not generally noticed immediately, all three hands for the chronograph complication are red, also enhancing legibility and distinguishing them from the timekeeping hands. The curved sapphire crystal prevents it from being a glaring mirror, and is virtually scratch proof. The dial is readily visible through it in all types of light.

For its size, this is a thick watch at 15.5mm. It's driven by the thickness of the ETA 7750, which is one of the thicker chronograph movements, combined with the layered dial and curved crystal. You can see how the back is extended downward with a bevel to mitigate this visually. Nevertheless, it will stand proud from the wrist some. At 217 grams, it's not a heavyweight, but neither is it a lightweight, and it's heavier than many watches in its size class. Part of it is the square case and crystal, and part of it is ETA 7750, which is also heavier. If you're not accustomed to a thicker watch or haven't worn one for a while, and you will notice its height when wearing it, a phenomenon common to nearly all ETA 7750 powered chronographs. In addition to the subtle "T" in the bracelet end links, the octagonal crown is also signed. The one small nit I have with the Quadrato is the octagonal crown. It fits the style very well, but it is a little more difficult to grip between the pushers when trying to manually wind the watch, requiring a little more time and effort compared to many other watches as it cannot be rapidly turned between the thumb and forefinger. Day/date quick-set and time setting are fine and without any problem as the crown is pulled out some, it's only when trying to wind it.

The brushed finish bracelet has solid machined links, including the end links that attach to the watch. Clasp is a double pushbutton butterfly deployant, with signed end links attached to it. It includes two half links for fine tuning the length to fit the wrist more precisely, a requirement when this kind of clasp is combined with links having any appreciable length. Closure is firm and solid. I've never worried about it springing open on me. Note that proper bracelet sizing will not have the watch tight on the wrist. It's hard on the clasp and the springbars that attach the bracelet to the watch head. Too tight can ultimately lead to a springbar failure even though they're quite surprisingly very robust. It should have a very slight looseness. If you open and close your fist completely a few times and feel it binding on your wrist, it's too tight. If it rides up onto the back of your hand, it's too loose.

Tissot put an interesting display window on the back. It is reminiscent of an old Victorian era window, with rays emanating from the semicircle positioned over the balance wheel, as one might expect from a sun. The smooth finished movement has a signed, gilt rotor with Geneva stripes. The back appears to be a form of snap on, which isn't surprising for a square back, the alternative being multiple screws. Even though the back doesn't screw down, nor do the crown or pushers, it still has a respectable 100m water resistance. I wouldn't swim, hot tub or shower with it, but you can be confident that it will survive a heavy rain and everyday encounters with hand washing without worrying.

Numerous reviews of chronographs containing the ETA 7750 mention "rotor wobble." It's not really a wobble. The rotor on most current automatic watch movements will wind the watch in both directions. Originally, the first auto-wind mechanisms in the mid-1920's could not make a complete rotation. There were bumpers to prevent it. These are referred to as "bumper wind" movements by collectors now, and one could feel the rotor hitting the bumpers, at least occasionally. The auto-wind mechanisms were improved in the 1930's to allow full 360 rotation eliminating the bumpers, but they only wound the watch in one direction and freewheeled in the other direction. Eventually several different types of mechanisms were designed to allow winding in both directions. The most elegant and simplest of these was created by Seiko, called the "magic lever." While the huge majority are bi-directional winding, there are a number of movements still made that only wind in one direction. The ETA 7750 is one of them. Other notable uni-directional movements include the Miyota 8000 family, the new Miyota 9000 family (which surprised me), and the ETA 2001-1, a reduced size movement based on the ETA 2892A2 design. A characteristic of the unidirectional wind is freewheeling in the other direction. Occasionally, rapid or sudden wrist motion will set the rotor moving in the non-winding direction with more energy than normal, and without any winding resistance it will freewheel rapidly. While it doesn't cause any harm as the rotor arbor and bearings are designed for it, one can hear and sometimes feel this when it occurs. This is the "wobble" that isn't a wobble, but rotor freewheeling.

The lume is surprisingly bright and bold, especially on the main hands, given that it's neither a tool nor a sports watch. That was a pleasant surprise. The other surprise was the small rectangular strip of lume on the chronograph central seconds hand. I wouldn't expect lume on the small timekeeping sub-seconds hand as it wouldn't be very legible at arm's length. I came to the conclusion the chronograph central seconds lume is to at least let you know the chronograph is still running and measuring elapsed time in dim light or darkness. The ETA 7750 hour totalizer can accumulate up to 12 hours. It's entirely possible someone might be timing a very long event starting in daylight that continues into the night.

Overall, the Tissot T-Trend Quadrato auto chronograph is a unique one in a world of overwhelmingly round dial chronographs. It's very solid and well built with a robust feel that gives confidence in its durability. It's definitely not fragile. While maintaining a bold and edgier Tissot style, it doesn't have a tool or sports watch appearance, which allows it to wear well with semi-formal social and business attire (i.e. coat and tie).

Eat your heart out, Walter White. I don't need a Monaco.
I've got a Quadrato!

Bulova’s Swiss Made Collections, Accutron Name and Logo, and Accu-Swiss logo: 
Prior to August 2014, Bulova had used the Accutron name for its top tier Swiss Made watches. The tuning fork logo was prevalent, but it was used even more so in the Accutron line, which included the mostly mechanical and most expensive watches. There were named collections within the Swiss Made Accutron line, each with their own unique case, bracelet and dial styles. Among them were the Curacao, Gemini, and the Corvara reviewed here. In August 2014, Bulova announced it was changing the Accutron label and its tuning fork logo usage. The Accutron name would only be used on high accuracy quartz precisionist movement watches with the label “Accutron II” to distinguish between these and the Accutron labeled watches that preceded them. “Accutron” alone would no longer be used. In addition, the tuning fork logo would only be used with the “Accutron II” labeled watches, and would not be used on any others. The Swiss Made collections that had been labeled “Accutron” would now be labeled “Accu-Swiss” with “Accutron” and the tuning fork logo removed from their dials, crowns, case backs, movement rotors, bracelet, presentation boxes and all other materials associated with them. The “Swiss Made” marked Accu-Swiss are just now finding their way into retail channels. It’s apparent Bulova is attempting to emphasize its Precisionist quartz line in its marketing with the Accutron II label and tuning fork logo. Bulova’s overwhelming market demographic is North American in which quartz is the overwhelming technology and mechanical watches are a very tiny niche.
Bulova named some of its Accutron collections after geographical regions. Corvara is a very small resort town in South Tyrol, an autonomous province in northern Italy that was part of the Austro-Hungarian Empire prior to the end of WWI. Corvara is known for the Alta Badia ski resort, a regular stop on the Alpine Skiing World Cup schedule, and the annual single-day Maratona dles Dolomites (Dolomites Marathon), an amateur bicycle race with 9000 cyclists that climbs seven high altitude passes in the surrounding Dolomites. It’s definitely not for the casual cyclist; the Giro d’Italia (the Italian “Tour de France”) uses much of its 86 mile route. I suspect the Accutron Corvara’s graphic design may have been inspired by ski tracks on Alta Badia’s ski runs.

Pinstripes dominate the Corvara and its unique octagonal case, from its bezel, across the dial, and through the center links around the bracelet. Prominence of the dial pinstripes depends on lighting angle. The lumed tips on the skeleton broadsword hour and minute hands prevent them from being lost visually on the dial regardless of lighting. The seconds hand has a tuning fork tail, a nice design detail. The wide integrated bracelet has equally wide 17mm center links. Under 10X magnification the fixed bezel appears to be a separate piece attached with real screws, but I have not tried to loosen any of them (doing so would risk marring their slots). The Integrated bracelet attaches between the lugs with its 17mm wide center link. The sides of the first outer links align with the lug sides. This gives a continuous, smooth visual flow, in addition to the pinstripes, from case to bracelet. Pinstripe surfaces of case and bracelet are brush finished in the direction of the pinstripes. Smooth top and side surfaces on the case and bracelet have a high polish mirror finish. Strap lovers would be frustrated with the case and lug design. A custom made strap would have to be created specifically to fit the case and lugs in much the same manner as the bracelet does. The 42mm case length, and even more important the 50mm lug-to-lug length might worry those with smaller wrists. Whether a larger watch head fits a smaller wrist depends considerably on the lug and bracelet design. The lugs curve downward with the bracelet end link between them falling away at a steep angle. The watch appears visually large, but the lug design combined with a 12mm case thickness make it wear smaller than some 40mm watches with traditional straight lugs. It fits me without any problem or appearing too large for my 7 inch (18cm) wrist.

Build quality is impeccable with great attention to precision fit and finish. Aspects of the design show attention to small practical details. The slight curvature and AR coating on the sapphire crystal greatly mitigates reflections from its surface which could be an annoyance, particularly with a black dial. It is so slight that I did not notice it until measuring the case dimensions. Case and bracelet have ample radiusing on edges and corners. This produces a smooth, softer and pleasant feel from the stainless steel on the wrist.

The butterfly deployant with twin pushbuttons works much smoother and easier than the snap type that uses an interference fit closure.

Power plant under the dial is the venerable 25j 28.8kph high-beat ETA 2824-2 workhorse. There’s nothing exotic about this ETA movement, but there doesn’t need to be. It’s a precision made, high reliability and very durable movement with a proven track record.

Lume is bright and nicely applied to all the hour markers, except at the 12, making orientation obvious. Marker at the 3 is truncated by the date window. The semi-skeleton hands have slightly brighter lume at the tips to make them stand out from the hour indices.

The standout features of the Corvara are its pinstripes, unique octagonal case shape, excellent materials and build quality with a very robust ETA movement, and attention to small details that make it comfortable to wear and practical to use. Bulova’s Swiss Made line, formerly Accutron, now called Accu-Swiss, is a sleeper among the mid-tier watch brands. They’re in a class with Longines, Rado and Union Glashuette. Rated to 100m water resistance without a screw down crown, this is a casual sports watch that could easily transition from a morning on the golf course to a 3-piece pinstripe suit for a business meeting in the afternoon without looking out of place. With some perseverance, models such as this Corvara can be found NOS (Brand New in Box, Old Stock) on the Internet for a fraction of their original “street” price.
Bracelet sizing note:
Removable links do not have the common split pin. They have a solid pin with center notch and mating sleeve with notch that fits into the center links. Drifting them out requires a drift small enough in diameter that it can fit into the center sleeve without binding. Most link pin drifts are too large; I made one of my own specifically for these. In addition, when removing the pin and pulling the links apart, take care not to lose the sleeve as it will fall out of the center link as soon as you pull the links apart. It's small and you don't want to be searching for it on your floor, especially if it's carpeted! If in doubt about dealing with this type of link fastener, take it to a reputable jeweler with its own in-house repair shop. They'll know exactly what these are as it's a standard fastener, but not nearly as common as the split pin.

About Xezo:
Xezo is a small micro-brand company in Texas that makes and sells men’s accessories: pens, sunglasses and watches. Their designs are inspired primarily by architecture and history. The watches are designed by Xezo and built to specification by a private label watch company in Lengnau, Switzerland, hence the “Swiss Made” label on the dial. Xezo makes all its watches (and its sunglasses and pens) in limited edition production runs, typically 500. While a case design may be reused, the dial and possibly the movement and its features will be different. Not that well known in watch collector circles, Xezo sells directly online through its web site, and puts some of their products on eBay (under Xezo), Amazon (also under Xezo), and Overstock.

An architecturally inspired design, the curved case pays homage to 1930’s era Art Deco rectangular tank watches in an updated larger contemporary size. The columns on each side and the rows of small windows at the top and bottom are inspired by the columns and porch in the ancient architecture of the 405 B.C. Erechtheum Temple on the Greek Acropolis. "2001" is the year Xezo was founded. The curved case is unique with two outrigger columns on the left and right side with the crown located in the gap on the right side, providing it with protection. See-through windows at the top and bottom represent the temple’s porch. As with the 1930’s rectangular curved cases (e.g. the Gruen Curvex), the curvature allows its 48mm length to conform to the wrist better. It easily fits my 7-inch (18 cm) wrist. Back is a rectangular snap down with sapphire display window allowing view of the entire movement. 20mm width bracelet attachment using standard spring bars is concealed just under the case ends. The crown is large enough, and the case and column thin enough, that it’s easy to operate when not wearing the watch.

Dial is a two layer, with the upper one separated from the lower by a silver oval. The oval contains minute and seconds tick marks, with 10 minute Arabics just inside the oval. Unobtrusive small lume dots for each hour are also on this ring. Outer, upper layer contains the hour indices, a combination of Romans, Arabics and narrow lines extending to the dial edges. Texture is a subtle guilloche, oval basket weave that changes appearance with lighting and light angles on the dial. Lower layer inside the oval is smooth without texture, and contains the small 10 minute Arabics, model name and framed date window. Date wheel is black with white numerals to match the dial.

Bracelet is very high polish, mirror finish slightly curved panels with twin pushbutton butterfly clasp. Removable links are fastened together with standard “split pins” and the links have arrows on the underside showing the direction for removal (insert in opposite direction). Two half-links are provided on each side of the clasp, which helps with more precise sizing adjustments. An interesting design, the curved panels have no gap between them. Their curvature allows them to conform to the wrist without having to flex much at the joint between the links. The same leather strap mounted on the BA model (leather strap only) is included in the watch box. A signed deployant is mounted on the strap. That’s a big plus for the BAS model as buying the Xezo Architect bracelet for the BA later would cost a lot more than the price difference between the BAS and BA.

The ETA 2000-1 movement is an 8¾’’’ (19.4mm) downscaled version of the 11½‘’’ (25.6mm) ETA 2892A2. It is designed for use in smaller watches that cannot accommodate larger 11 ½’’’ movements. With the same 3.6mm thickness as the 2892A2, it also allows for thinner cases than the 4.6mm 2824-2. The 2000-1 has many of its big brother’s attributes, with the notable exception of a unidirectional auto wind that eliminates the space required for a bidirectional mechanism. Found more often in women’s watches, this movement’s smaller size allowed for an 8mm thick narrower case with two outboard columns and a dial with a date window inside its oval.

The standout features of the Architect 2001 are its unique Art Deco architectural design, unique mirror finished paneled bracelet, case and bracelet curvatures to conform to the wrist, and a movement that allows a thinner watch in keeping with its style. Dial and hand lume are camouflaged by the oval ring and hand design. Build quality is excellent with top drawer materials, and precise fit and finish work.

The Xezo Architect 2001 contemporary size and design elements combine to create a watch that can be worn with informal (business suit) to formal evening attire (white tie) with ease. It’s the watch you want when the mondo wrist wart diver, military or aviation tool watch you normally wear looks out of place when dressed up to the nines. This is my second Xezo and it’s a high quality, well-made watch.

I have no affiliation, association or financial interest with Xezo, or any of their distributors or dealers.

From the manufacturing date, this is obviously not a new watch and I've owned it for several years. It was found languishing as "new old stock" in the original box with tags a few years ago in the Internet store-front of a German watch dealer. I had been very patiently searching for a good watch with an ETA 7001 inside at an attractive price for several years. What I had been finding was either decidedly not my style or was priced higher than I wanted to spend.

Aristo is a German company in Pforzheim, one of several traditional German watchmaking regions. They're joined at the hip now with Vollmer, having merged under the same ownership and management. Vollmer is a maker of upmarket metal watch bands, also located in Pforzheim. The U.S. Vollmer distributor sells watches under that branding as well (very similar to Aristo in style). Some watchmaking has remained in the region, but it's not nearly what was there prior to WWII, or after the Japanese quartz onslaught. German mechanical movement and watchmaking didn't survive nearly as well as the Swiss did. There has been some growth in recent years, but it's been very slow. Aristo's main products for some years now have been aviation and aviation related watches, with some maritime, u-boat and marine watches. In addition, they currently offer several models in the style of vintage auto gauges, and some general military field watches. They're generally the contemporary standard to larger men's sizes (standard to large for watch brands other than Android or Invicta). The company owner also had a penchant for thin dress watches, creating his 7001 models in 2003. They didn't last more than a couple years in their collection, perhaps because dress watches of their size were so different from the Aristo norm. It was followed by a similar, slightly larger line for a couple years.

The ETA 7001 was designed by Peseux and put into production in 1971. Peseux was folded into ETA during the huge collapse and consolidation of Swiss movement and watch companies in the 1980's as the Japanese quartz Juggernaut nearly wiped them out. The 7001 is one of the movements to survive the drastic reduction in watch movement calibers, no doubt due to its unique 2.5mm thinness in a mid-size 10.5''' (23.3mm) diameter. Compare that to the 3.6mm, 11.5''' (25.6mm) ETA 2892A2, or the even thicker 4.6mm ETA 2824-2. One can argue that at 2.5mm, it's the thinnest standard mechanical caliber in current production available to watch makers (assemblage brands buying ebauches and whole movements versus manufactures making in-house movements).

There are thinner mechanical watches and movements, but the movements are in-house and proprietary (i.e. not available to other watch companies). The current record holder I'm aware of is the VC 1003 manual wind movement, at a mere 1.64mm (VC = Vacheron Constantin). It is a significant evolution of the 2.94mm VC 1001/1002 which were derived directly from the thicker JLC 818/819 (JLC = Jaeger-LeCoultre). If you want the 36mm diameter, 4.13mm thick VC 1003 powered watch, currently the thinnest mechanical on the market, you'll have to pony up about $25,000 USD for a Vacheron Constantin Historiques Ultra-Fine 1955. The rest of us proletarians will have to settle for 1.87mm thicker watches like this 6mm Aristo, which, by the way, boasts a seconds hand Vacheron Constantin jettisoned in creating their VC 1003 movement to squeeze it down further. As thick as it is by comparison, I haven't met a shirt cuff yet this Aristo won't fit under!

The 1.5mm thick Vollmer Milanese band is a good match-up for the thin watch head. It works well aesthetically with the shorter lugs, without the unduly large and unsightly gap watch heads with longer lugs create when straight end bands are put on them. The crown is also proportional to the watch head and its onion style shape provides a good grip for winding and time setting in spite of its smaller size. The coin edge bezel matches the crown knurling and Milanese band. It's a combination of function and harmonious aesthetic that shows thoughtfulness in the complete design.

In spite of their narrow width, Aristo put some lume down the center of the bayonet hour and minute hands. It's only about 1/3rd their width, but it shows up quite brightly. It's not a Seiko Monster beacon, but it does glow sufficiently for a while in dim lighting. One might wonder why no lume around the hour indices. A lume dot large enough to make it reasonably visible would clutter the dial. I've not had a problem discerning the hour and approximate minutes without hour index lume (the time above is approximately 1:50).

Most ultra-thin watches suffer from a two dimensional appearance, as if they were printed onto a strip of plastic, mylar or paper. It starts with plain flat enamel dials with ultra-narrow flat stick hands, and continues with smooth flat bezels surrounding them. The strap is typically very thin and flat with no texture. Their stark plainness is not very interesting visually. The Aristo has a textured, coarse basket weave dial, very slightly raised hour indices, along with a raised ring around the seconds sub-dial and around the inner dial separating the basket weave from the hour indices. The combination of dial textures, coin edge bezel and onion crown with the Milanese band give it visual interest and depth, in spite of its extreme thinness, and their subtlety maintains a simplicity of style.

There are formal and semi-formal occasions when the large sports or tool watch isn't an appropriate match for the attire. A smaller, thinner and less conspicuous dress watch is called for. It's why I have a few formal watches. This Aristo is one of them.

I have no affiliation, association or financial interest with Aristo, or its sister company Vollmer, or any of their distributors or dealers.
