Grand Seiko’s First Limited Editions of 2023 Celebrate the 25th Anniversary of the 9S Caliber Worn & Wound

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...

Grand Seiko Introduces the Spring Drive 5 Days Caliber 9RA2 SJX Watches
Grand Seiko Introduces Aug 24, 2021

Grand Seiko Introduces the Spring Drive 5 Days Caliber 9RA2

Having introduced a new design language along with the all-new, automatic 9SA5 last year, Grand Seiko is now doing the same for the Spring Drive. The watchmaker has debuted a pair of Heritage Collection Seiko 140th Anniversary Limited Editions, the “Minamo” SLGA007 in steel and the “Tree Rings” SLGA008 in rose gold. Both are powered by the 9RA2 that’s part of the family of latest-generation Spring Drive movements first seen last year in the Grand Seiko Diver 600 m SLGA001. Just 5 mm high, the slimness of the 9RA5 means the pair of new models are the thinnest Grand Seiko Spring Drive watches to date. Initial thoughts The new models are essentially Spring Drive versions of the self-winding Heritage models launched last year (including an ultra-luxe platinum version and the more recent “White Birch”). That’s a good thing for two reasons. One is the intrinsic appeal of the design, which is vintage inspired and appealing, packaged in a case that’s a good size and easily wearable. And the other is the increased consistency in styling between Grand Seiko’s Spring Drive and automatic models, doing away with the confusing distinction between movements and designs. The “Minamo” SLGA007 in steel But that’s also the downside for the buyers of the limited-edition models (either these or the automatics), since the design has been replicated as a standard-production watch with the automatic movement, and the same will surely be done for the new 9RA2 Spring Dr...

Watches & Wonders: Roger Dubuis Debuts an All-New Perpetual Calendar Caliber Alongside a Sporty Version of its Excalibur Biretrograde Calendar Worn & Wound

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 Worn & Wound

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...

Grand Seiko Adds a New Dress Watch with the 9SA4 Caliber to the Collection, Plus a New Tentagraph

Almost as soon as Grand Seiko released the SLGW002 and SLGW003 at Watches & Wonders 2024, we started to wonder what this new class of manually wound dress watch from one of our favorite brands might look like in different variants. This seemed like a natural platform for expansion, and we figured it was just a matter of time before we saw some alternative dial options and new metals. In the year and a half or so since Grand Seiko introduced these watches, and the 9SA4 caliber powering them, things have been quiet on the manually wound dress watch front. That is, until this week, when we finally got a peek at the new SLGW007, Grand Seiko’s first new launch with this case and movement since the big debut at Watches & Wonders last year.  While the most obvious update on the surface here is certainly the new dark blue dial, it’s actually the case itself that really has my interest. The SLGW003, you’ll recall, was crafted from Grand Seiko’s Brilliant Hard Titanium. This is a very cool material, for sure, but has a niche appeal in a classically styled dress watch like this thanks to its ultra light weight and the associations we all have with titanium and tool watches. The SLGW007 is in stainless steel, and I’m incredibly curious to see how this might change the character of the watch on the wrist. One would certainly expect it to be a bit heavier, but I imagine the finishing will also have a slightly different, perhaps more traditional look to it, at least in the con...

Horage Debuts the K3, an All New Antimagnetic Caliber, and the Decaflux, an Affordable Everyday Sports Watch Worn & Wound

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....
