[VIDEO] Grand Seiko Redefines Accuracy - Again: Introducing the 9RB2 U.F.A. Spring Drive Caliber
2022: the Kodo constant force tourbillon. 2023: the Tentagraph hi-beat mechanical chronograph. 2024: the 9SA4 manual wound, hi-beat, dual-impulse escapement caliber, and Kodo Daybreak. It’s easy to forget that Grand Seiko has brought the proverbial heat to Watches & Wonders every year since the fair started, unveiling something that one could call “revolutionary” for the brand, if on varying scales. Well, it’s looking like 2025 will continue the trend with the introduction of Spring Drive Caliber 9RB2, the first caliber with U.F.A., or Ultra Fine Accuracy, designation. Before proceeding, there are two important concepts to understand: Spring Drive and Grand Seiko’s history with acronyms (which, if you know, feel free to jump two paragraphs ahead). Starting with the former, the elevator pitch, which I will take from our article dedicated to the topic is “Spring Drive combines the best of mechanical watchmaking and the best of quartz timekeeping to create a state-of-the-art caliber that lacks the weaknesses inherent to both of these movements.” A bit deeper, Spring Drive movements use the energy stored in a traditional mainspring to drive their proprietary “Tri-synchro” regulator, which replaces the classic lever escapement. It consists of a glide wheel, the rate of which is controlled by an electromagnetic brake, and is essentially regulated by an integrated circuit with a quartz oscillator. The result is a mechanical movement with quartz-like accuracy and...

Up Close: Citizen Caliber 0210 “The Citizen”
Citizen launched its flagship mechanical watch, the Caliber 0200, two years ago. Despite being better known for high-end quartz watches – including the most accurate ever – the Japanese watchmaker managed an impressively executed three-handed sports watch, with an equally outstanding new movement. Now the model finally receives a mechanical upgrade with the Caliber 0210, which incorporates a date along with subtle improvements to the external design, while retaining the excellent case and bracelet that define the model. Initial thoughts The Caliber 0210 indicates the brand’s interest in further developing this excellent model – encouraging for fans of the model like myself. Despite the Caliber 0210 looking much like its predecessor, it is actually a substantially different watch in tangible terms. Ordinarily the addition of a date would be a no-no for a purist enthusiast, but here the date is integrated well in terms of dial proportions and (re)design. The appealing attributes of the Caliber 0200, and now the Caliber 0210, clearly mark the two out as watches conceived for a niche audience, namely enthusiasts who appreciate quality – and are able to distinguish this from the competition (Grand Seiko to state the obvious). However, this target audience often prefers the purity of a three-hand watch without a date. At the same time, this audience comprehends the substantive upgrades in the Caliber 0210 beyond the date – amongst them the improved case constructi...

This 1932 Bulova White Prince jump hour / direct read dress watch is truly rare, and this example is in superb condition. I used to collect these 1930’s Deco Bulovas and this has to be the nicest one I’ve ever seen. The hour, minute and seconds are shown on rotating discs through the viewports cut into the case.

Grand Seiko Introduces the Caliber 9S 25th Anniversary SBGH311 and SBGR325
When Grand Seiko (GS) made its return in 1998, the inaugural SBGR001 model was powered by the 9S55, the first modern-day GS calibre. Now the brand is marking the 25th anniversary of the 9S movement family with a pair of limited editions. The Heritage Collection Caliber 9S 25th Anniversary Hi-Beat 36000 SBGH311 and the Heritage Collection Caliber 9S 25th Anniversary SBGR325. The Hi-Beat SBGH311 has a patterned dial, while the more affordable SBGR325 has a dial with a brushed finish. Both are modelled on the original model of 1998 and sport the same 37 mm case. SBGH311 (left) and SBGR325 Initial thoughts With their 37 mm cases and clean styling, the new 9S pair hark back to the GS watches made from the late 1990s to mid 2000s. That is unsurprising since they are meant to commemorate the first model with the 9S movement, which made its debut in 1998. The Hi-Beat SBGH311 does have a fancier pattern dial, but one that is relatively subtle in its shades-of-grey texture. As a result, they will appeal to anyone who wants a smaller, simpler GS watch. Another upside of the relatively simpler execution are the prices, which place the pair amongst the most affordable self-winding GS watches. The SBGH311 is US$6,600 and the SBGR325 about 20% less. SBGR325 Old-school size The SBGH311 has a textured dial in silvery grey inspired by clouds that’s matched with a blued-steel seconds hand. And the “GS” emblem is gilded in a nod to the fact that this is an anniversary edition. Not...

Citizen Introduces the Caliber 0200 “Japanese Armor”
A year ago, Citizen debuted its first all new, high-end mechanical watch in decades, The Citizen Caliber 0200. A wristwatch par excellence, the Caliber 0200 was so good that it was one of our tops watches of 2021. Now Citizen is following up with the Caliber 0200 “Japanese Armour”, the first limited edition of the model that’s available globally. Topped with a black ceramic bezel and textured dial, the samurai-inspired Caliber 0200 has a low-key aesthetic that still distinguishes it from the all-steel models. Initial thoughts Even though production hasn’t yet caught up with demand – there’s still a waiting list for the watch – the Caliber 0200 is still a niche product, just because it is a high-end, mechanical offering from a brand better known for its solar-powered or quartz watches, and mostly affordable ones at that. So a limited edition makes sense, since the small run will boost desirability and create buzz worldwide (Citizen did launch a 50-piece limited edition last year that was sold only in Japan). That said, the new edition is still very much a restrained design that’s almost monochromatic. It’ll be one of those watches that are recognised only by those in the know. Interestingly, both the new limited edition and the standard model stick to the same palette – grey, silver, and black – with the difference between the two being the quantity and intensity of each colour. On the limited edition, black becomes the dominant colour thanks to the ...

The Nomos Metro Gets an Ice Blue Color Scheme and a Brand-New Mechanical Caliber
Earlier this year, I got a whole new appreciation for the Nomos Metro after sitting down with its creator, Mark Braun. The collection first came into the Nomos catalog back in 2014 and debuted the brand’s proprietary swing escapement system, which was developed over seven years with the Fraunhofer Institute and TU Dresden. Form was equally important to function in the original design, featuring a galvanized and silver-plated dial with a soft white color punctuated by black, red, and green markings in an arrangement that subtly played with asymmetry. Over the past 12 years, the Metro has gone on to take many other forms – some ditching the asymmetry by removing the power reserve indicator and shifting the Nomos logo to 12 o’clock and others ditching the white dial for full color alongside versions in rose gold as well as special editions for select markets. Today, we get the next evolution with the Metro Date Power Reserve Ice Blue. True to the collection’s DNA, this new incarnation offers new details both aesthetic and technical, including a brand-new mechanical caliber.With the latest addition to the Metro lineup, we see Nomos continue to use this collection as a launch point for new technical advancements. It marks the first model in the Nomos catalog to house the new hand-wound caliber DUW 4701, which offers a patented quick-set date and a power reserve of up to 52 hours. This entirely new movement continues the story of mechanical innovation that began with the...

Introducing: The Nomos Glashütte Metro Date Power Reserve Gets A New Caliber (Live Pics)
What We Know If you asked me to pick a watch from the catalog that best represents the small but mighty German brand Nomos Glashütte, I'd probably choose the Metro Date Power Reserve. Sure, it's not the distinctive Tangente, nor is it a simple Club Campus. But I think the Metro Date Power Reserve embodies so much of what makes the brand special to me—a beautifully considered, minimalist design by designer Mark Braun, a splash of color to make it interesting, a quirky power reserve indicator, and an in-house manually wound movement with the finishing you'd expect from the brand. That's why I bought mine a few years ago, and I've enjoyed it ever since. However, unlike many other watches in the lineup, the Metro Date Power Reserve is a tricky model to recommend to friends, especially those just starting out in this dangerously addictive space. That's because for all that the watch delivers, it has its Achilles' heel in the form of a non-quickset date. Yes, that means that if you haven't worn the watch in a while and the date is off a bit, you'll need to keep moving the hands back and forth past midnight to advance the date every single time. If you're fifteen days out, it gets tedious, and there's no way around it except to accept that your watch shows the wrong date. Luckily, after more than a decade in production, the model gets a new refresh. Today, Nomos brings a new in-house caliber, DUW 4701, to power the new generation of Metro Date Power Reserve. Most importantly, ...

Hands-On: the Wolbrook JetFlyer and the New Jeambrun PS6402 Automatic Chronograph Caliber
I’d like to think I am a bit of a movement nerd. Not in the sense of knowing all of the technical attributes (actually, I wish I knew more there), but rather about what movements are on the market from the major suppliers. Hand me a watch, even with a complication, and I can probably tell you what movement it has in a matter of seconds (assuming it’s mechanical) by the positioning of the hands, complications, rotor bearing, etc. So, last fall, when I was handed a prototype of a new chronograph by Wolbrook and, upon seeing the dial, realized I had no idea what movement it had, my interest was piqued. The watch was the Wolbrook Jetflyer, which I have since had the opportunity to spend more time with. An extension of the French brand’s proven line of tool dive watches based on vintage models, the Jetflyer is their first foray into mechanical chronographs. As the name suggests, the Jetflyer is not meant as a “dive” chronograph, but rather as a pilot’s, though that’s largely semantics, as there are a lot of overlaps in design language (and the WR is 100m). I’ll get back to the particulars of the design, because what really stands out is the movement. $845 Hands-On: the Wolbrook JetFlyer and the New Jeambrun PS6402 Automatic Chronograph Caliber Case Stainless Steel Movement Jeambrun PS 6402 Dial Mattte Black Lume X1 Super-Luminova Lens Domed Sapphire Strap Leather or Bracelet Water Resistance 100m Dimensions 38 x 46mm Thickness 14.3mm Lug Width 20mm Crown Screw-d...

Zenith Reimagines Its Caliber 135 For The 21st Century
The year 2025 marks 160 years since the founding of Zenith in Le Locle, Switzerland, back in 1865. As watchmaking brands are wont to do, Zenith is commemorating this milestone by putting forward a watch for the occasion that’s representative of its storied history, as well as its own contemporary identity. Now, as Watches & Wonders 2025 kicks off, we are clear on how the brand aims to celebrate the occasion, and its chosen vehicle is a new collection inspired by Zenith’s own founder, complete with an update on its storied Caliber 135, which breathes fresh life into an old favorite movement. These are the conditions in which the rising star of the G.F.J. collection joins Zenith’s constellation. At the tail end of the 19th century, the mounting competition within the watch industry brought about a new standard of gauging the accuracy of movements, and watchmakers began employing observatory trials to signal to customers that their products were as accurate as possible. This was also at a time in which highly accurate timepieces were necessary for successful marine navigation. Before the COSC certification standards that are so rigidly defined today were coded, individual movements would be sent to observatories, where they would undergo testing procedures, as well as competitions for chronometry prices. Zenith details that it had been routinely entering chronometry trials as early as 1897. And, because a bit of healthy bragging is appropriate with brag-worthy achieveme...

Yema Introduces a New Skin Diver with their Micro Rotor Caliber
French watchmaker Henry-Louis Belmont established Yema in 1948 and quickly became known for manufacturing ultra-capable tool watches. By 1954 their production reached 130,000 watches and by the mid 1960s they were selling over 400,000 watches annually in 55 countries. Their motto “Time of Heroes” became their official slogan, and their watches were particularly suitable for diving, car racing, and military expeditions. Today, Yema is experiencing a resurgence and is introducing a new modern interpretation of their iconic Skin Diver. The Skin Diver Slim CMM.20 is not just another pretty face. Beneath the beautiful dark grey dial beats their in-house Calibre Manufacture Morteau 20 movement (CMM.20). It is rated for accuracy at -3/+7 seconds a day, has a power reserve of 70 hours, and is extra slim due to its micro-rotor. The watch measures 39mm in diameter, 47mm from lug-to-lug, and only 10mm tall to the top of the double-domed sapphire crystal. Despite being relatively thin, it is water-resistant to an impressive depth of 300 meters. Adding to its vintage styling is a dark grey, faded bezel insert covered by sapphire glass. Its lume pip, along with all the lume on the dial and markers, has that aged radium look, which complements the design very well. The watch comes mounted on a new slimmer Yema Scales bracelet, which integrates better with the Skin Diver’s slimmer profile. The screw-down case back offers a transparent view of the movement, featuring a black ALD (ato...

Depancel Introduces their First Série-R Watch with an Automatic Chronograph Caliber
Depancel has carved out a nice little niche for themselves making highly specific automotive and racing inspired watches. These watches are frequently geared directly at watch collectors who are already steeped in car culture, with colorways inspired by classic racing liverys and case designs that emulate specific vehicle designs. Their square shaped watch, the Série-R, might appear somewhat derivative of another famous square watch connected to the racing world, but it has its own thing happening that sets it apart just enough. And this one, surprisingly, is the first chronograph in the Série-R collection. Previous iterations of the Série-R have primarily been the home of a calendar complication with an execution that is chronograph-like, featuring subdials at 3, 6, and 9 for the calendar indicators. The new Série-R, in a “Tangerine” colorway and limited to 300 pieces, could have been easily predicted by Depancel fans. We get effectively the same layout as the calendar, but we’ve entered race mode with a three register chrono. The new Tangerine colorway looks great, with a blue base dial with a sunray finish in the interior circular section and vertical ridges outside to fill the square. Orange and white accents figure prominently throughout, with a bold stripe down the dial’s left side, crossing the 9:00 subdial. The case might appear like a standard square at a glance, but there’s a little more going on. The shape is meant to evoke a radiator grille,...

Grand Seiko’s First Limited Editions of 2023 Celebrate the 25th Anniversary of the 9S Caliber
It’s an often repeated mantra around here: every year is an anniversary year. And if a watch brand is going to be successful in today’s hyper competitive market where, frankly, a lot of brands are offering products that are remarkably similar to one another, they need to differentiate themselves. And looking at a calendar, and figuring out how many years it’s been since “X” accomplishment or “Y” watch was first released is (usually) a decent runway for explaining what makes you special. To that end, Grand Seiko is embarking on what will apparently be a year of celebrating the 25th anniversary of the Caliber 9S, a movement which has become foundational to Grand Seiko in the decades since its debut. The Caliber 9S has become a broad family of movements over the years, as Grand Seiko has continuously refined the caliber, including adding GMT functionality. Grand Seiko has used the 9S movements as a platform for their MEMS engineering techniques, which allow for insanely tight tolerances in movement making for certain key components, and you could probably argue that 9S movements represent the most traditional watchmaking currently practiced by the brand. Today, 9S movements are universally known to be reliable and rock solid high frequency calibers that often perform even better than the specs would indicate. Most recently, the 9S served as the springboard for the creation of Grand Seiko’s next generation Hi-Beat movement, the 9SA5. While it might not be t...
