Omega Resumes Production Of The Caliber 321 Movement
Based on the Lemania 2310 - a movement that would serve as a base for watches like the Patek Philippe 3970 - the original caliber 321 stands as the spirit of the "true" moon and pre-moon watches. As a column-wheel chronograph, it's also highly coveted by collectors due to the historical significance and purported superiority as well.

ETA 2824: The History and Legacy of a Legendary Workhorse Caliber
The ETA 2824 caliber has been a presence in the world of mechanical wristwatches for more than 50 years, helping the Swiss watchmaking industry forge a path through the Quartz Crisis and serving as the engine for hundreds of three-handed timepieces from an array of brands, large and small. While it is a rarity here in the 21st Century, its legacy can still be seen across the horological world - from the proliferation of similar movements by makers like Sellita to the increasing ubiquity of the ETA 2824’s souped-up successor, the Powermatic 80. Read on to learn everything you need to know about the ETA 2824. A (Very Brief) History of ETA Nearly everyone that follows the wristwatch industry has heard of ETA, and most of those have probably worn a watch with an ETA movement, but few are likely aware of the Swiss movement maker’s long and convoluted history. We generally trace its origins back to the formation of the historical watchmaking firm Eterna, in 1856 in the Swiss town of Grenchen. But in reality its roots reach even deeper. Eterna is perhaps most famous today as the maker of the Kon-Tiki dive watch, and it is currently owned by the Hong Kong-based Citychamp Watch and Jewellery Group. Originally however, the firm was a manufacturer of ébauches - unassembled movements for sale to outside watchmakers - and was named “Dr. Girard & Schild” for its founders, Dr. Joseph Girard and Urs Schild. Renamed Schild Frères by the next generation of owners, the compan...

Studio Underd0g Introduces the Third Generation of the 01SERIES Chronograph
I had the privilege of writing about the last Studio Underd0g 03SERIES Salm0n release for Worn & Wound in September. Serendipitously, Studio Underd0g was in Montreal the following week with the RedBar traveling road show. It was a real treat to see and handle their watches in person finally. They even had one of their Pizza watches and their Moser collaboration. The latter was quite exquisite, as was the new Salm0n, but part of me hoped that Studio Underdog wasn’t moving upscale, leaving behind what got them there in the first place: affordable, whimsical chronographs that make you smile when you look down at your wrist. When I learned that Seagull had announced a new minimum order quantity of 10,000 units for their ST-19 series movements, I became concerned about Studio Underd0g’s most popular model, the 01SERIES. This worry was heightened by the brouhaha that followed the collaboration with Moser and the decision to use Sellita-based movements in their 03SERIES. Fear not, as Studio Underd0g has successfully contracted Seagull to create an exclusive and enhanced version of their caliber called the ST-1901B. This reaffirms their commitment to providing mechanical chronographs priced under $1,000. For those unfamiliar with the history of the ST-19 column-wheel chronograph movement, its origins are Swiss. In 1961, Venus sold its machinery, tooling, and blueprints for the Venus 175 caliber to the Tianjin Watch Factory. They then upgraded the original 17-jewel movement to ...

A Week In Watches, Episode 63: Geneva Watch Days Special
In the special edition of A Week In Watches, Zach Weiss and Blake Buettner sit down together to discuss some of the most interesting new releases from Geneva Watch Days, and more. From blacked out Doxas, to kind of blue De Bethunes, and a Eucalyptus Ressence, there were plenty of new watches to appreciate, including the joint Only Watch submission from H. Moser and MB&F;. You can view more of our Geneva Watch Days coverage right here, and keep an eye out for more yet to come. Geneva Watch Days didn’t give us the only new releases last week, though. One of the biggest surprises, and a welcome one at that, was the new Seiko ‘Alpinist’ GMT Prospex references, which brings their 6R54 GMT caliber into the beloved field watch collection. It makes a whole lot of sense in this platform, even if it is a ‘caller’ style GMT, so we’re thrilled to see it makes its way over. This episode of A Week In Watches is sponsored by our friends at Shinola. To commemorate 10 years of American design and manufacturing, Shinola Detroit is proud to share this video that reveals the company and its employees as a team that can carve a distinct pathway forward with their own sense of, as they say, “timeless American design.” This cinematic video gives an insider glimpse of their watchmakers assembling timepieces, soaring views of the Detroit headquarters, and shares perspective on the past decade as well as Shinola’s aims for the future.

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 ...

Watches & Wonders: Roger Dubuis Debuts an All-New Perpetual Calendar Caliber Alongside a Sporty Version of its Excalibur Biretrograde Calendar
Roger Dubuis’ latest releases at Watches and Wonders are steeped in the brand’s history. For the occasion, the maison introduces two complicated pieces – a perpetual calendar and day-date calendar – each in the brand’s patented biretrograde display. Prior to founding his namesake maison, Mr. Roger Dubuis was a prolific watchmaker for several brands, from Patek Philippe to Longines. One such project came in 1989 when he and fellow watchmaker Jean-Marc Wiederrecht collaboratively pioneered and patented their famous biretrograde display, which reworked the traditional concept and made it more streamlined. This approach eased assembly and improved the stability and readability of the hands on the ecliptic retrograde counters. Soon after, the pair engineered a double retrograde perpetual calendar module, which was notably used in a timepiece for Harry Winston. A year after the brand’s official founding, Roger Dubuis introduced its own biretrograde display timepiece and later the perpetual calendar complication in its iconic Sympathie and Homage collections. Today, we see the next evolution of these concepts highlighted in a rather modestly sized 40mm version of its Excalibur line. The Excalibur Biretrograde Perpetual Calendar is notably powered by an entirely new movement: the RD850. Here, the maison builds upon the work set forth four decades ago with a self-winding caliber built from 435 components in-house at Roger Dubuis’ Geneva manufacture. A key functional i...

Watches & Wonders: the A. Lange & Söhne Saxonia Annual Calendar Returns with a New Case Size and Caliber
A. Lange & Söhne had one of my, and many others’, favorite releases at Watches & Wonders 2025. It wasn’t a super complication and had no bells-and-whistles. Rather, it was simple and small. The 34mm 1815 three-handers in white or rose gold exemplified confident, understated luxury like no other watches at the fair. For 2026, Lange has brought back a watch that had been out of production with a new movement and in a new, smaller size, following suit from last year’s release. Unlike the 1815s, these feature one of the less common complications in the Lange catalog: the annual calendar. The Saxonia Annual Calendar was a very cool watch. It combined its eponymous complication with Lange’s signature outsized date and was powered by a since-retired “Sax-0-Mat” three-quarter-rotor automatic movement. These funky movements were featured in the Langematik watches and represented Lange’s first foray into automatic calibers. In addition to a distinctive look, they featured a hidden complication: zero-reset seconds, meaning that when the crown was pulled out, the seconds hand would jump to zero. In 2011, the Sax-O-Mats began to be replaced by central rotor calibers with up to 72 hours of power reserve, an increase from 46 hours, but the zero-reset seconds disappeared. Though comprising many different calibers, most of Lange’s currently in-production automatics have a central rotor. I am unsure when the previous generation of the Saxonia Annual Calendar went out of pro...

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...

Horage Debuts the K3, an All New Antimagnetic Caliber, and the Decaflux, an Affordable Everyday Sports Watch
The independent brand Horage has produced some of the most genuinely interesting watches of the last several years. They’re a bit of a tough brand to pin down. Depending on how you discover them, you could mistake them for a brand obsessed with links between watches and photography, or one of a handful of small indies doing interesting things with tourbillons and other watchmaking tech for quite a bit less money than you’d typically expect. But the thing that links all of their products together is a desire to come up with creative solutions to long standing watchmaking problems and to do so in a way that doesn’t leave anyone out of the experience. Accessibility and approachability are as vital to Horage as their love-it-or-hate-it design language, often embracing an ultra contemporary sensibility. Two new announcements from Horage over the last week or so perfectly illustrate their commitment to quietly pushing horological boundaries. First came the introduction of their new K3 movement. Over the last several years, most of Horage’s big movement developments have come with some high end features and represent big swings for the brand. The tourbillon, of course, is arguably the centerpiece, but they’ve also introduced a micro-rotor caliber as well as a fascinating tool that allows for the periodic electronic regulating of that very movement. But the K3 is a comparatively simple idea, a high quality movement made from advanced materials at a relatively low cost....

Norqain Launches the Independence Skeleton Chrono with the New 8K Flyback Caliber
Norqain has just unveiled what is certainly their biggest release of the year, and quite possibly their most ambitious release since the debut of the Wild One two years ago. The new Independence Skeleton Chronograph expands on the design language we saw take shape with the Wild One, and introduces a new, skeletonized, flyback chronograph mechanism. The new watch is conceived as something of a statement piece, meant to highlight what the brand thinks of as their independent spirit, and launches in two variants that illustrate where a full collection of watches powered by this new caliber could potentially go. The movement at the center of this release has been dubbed the 8K Manufacture Calibre, and features flyback functionality, a tool that was first developed for chronographs used by pilots to time flight related intervals. Flyback functionality allows a running chronograph to be reset to zero instantaneously without first stopping it, so it’s a useful tool for anyone that needs to time multiple intervals in rapid succession (it has gained wide adoption in sporting contexts through the decades). The execution of this particular movement appears to have all of the hallmarks of a solid, modern chronograph movement, including a power reserve stretching to 62 hours, as well as a column wheel. The 8K caliber is also chronometer certified. It’s also worth noting that the 8K movement was developed in partnership with Manufacture AMT, a division of Sellita known for creat...

Photo Report: Assembling Caliber 9SA4 at the Grand Seiko Boutique
I’ve always had a fascination for peeking behind the curtain. Whether it was tearing apart broken electronics, rebuilding car engines, or opening the caseback of my first Seiko, I’ve always wanted to see and know how things work. As I’ve gone deeper into the horology rabbit hole, I’ve become more interested in the physical process of assembling a movement. While I can watch any number of YouTube videos, there’s something special about seeing it done in person, especially when you get to watch a Grand Seiko Watchmaker at work. Last week, I was invited to Grand Seiko’s boutique for a live assembly of their new 9SA4 movement, a high-beat, manually wound high frequency movement featuring Grand Seiko’s proprietary dual impulse escapement and 80 hours of power reserve. If you’d like to learn more about the 9SA4 and how it was created from the 9SA5, Zach Kazan covers that in detail here. This event was hosted at Grand Seiko’s Madison Avenue boutique (we celebrated the grand opening of this boutique in March, click here for the recap article) which features a gorgeous open concept main level, and an intimate lower level they’ve dubbed “The Cellar”.

You’ll also find various items of cultural significance from the towns surrounding the Grand Seiko Studio Shizukuishi, which inspire the design o...
