Is the new Norqain Adventure NEVEREST GMT 41mm better than the Tudor BBGMT?

I first encountered Norqain in the metal at the COUTURE Watch & Jewellery show in Las Vegas. I had heard of the brand prior, and one of the headlining aspects of their watches are their manufacture calibers developed with Kenissi – the same movement developer that Tudor, Chanel, and Breitling use.

With hope on the horizon, and borders hopefully beginning to open, the relevance of GMT and world timer complications is bit by bit returning. Heck, if you are like me, a part of an international team, than the GMT complication does come in handy even now when coordinating Zoom calls. Regardless of circumstance, it is … ContinuedThe post INTRODUCING: The Horage Supersede aims to deliver unprecedented value with new K2 micro-rotor GMT caliber appeared first on Time+Tide Watches.

Grand Seiko Introduces the Spring Drive 5 Days Caliber 9RA2 SJX Watches

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...

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...

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...

Yema Introduces a New Skin Diver with their Micro Rotor Caliber Worn & Wound

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...

Collective Horology Introduces their Latest Limited Edition, a Collaboration with Montblanc Featuring a Gorgeous Minerva Caliber

Collective Horology, the private watch club/independent brand retailer/producer of thoughtful limited editions, is back with their latest release in an ongoing series of collaborations. This time, they’re working with Montblanc, tapping into the brand’s association with the historic Minerva manufacture, maker of some of the most important chronograph calibers in the history of watchmaking. The 1858 Minerva Monopusher Chronograph “Blue Arrow” P.05 is a high end “What if…?” hypothetical come to life, and a great showcase for a truly special movement. As with all Collective limited editions, this one is something more than a reissue or a tweaked colorway. It exists to tell a specific story about the brand in a way that can often only be done from the outside.  According to Collective, the seed of inspiration for the P.05 came from Eric Wind, or more specifically a watch in his case at the 2022 Windup Watch Fair. That year, Eric brought a Minerva stopwatch to the show, and it reminded Collective founders Gabe Reilly and Asher Rapkin of Minerva’s sporting roots, opening up a series of entirely new design possibilities. The 1858 Monopusher Chronograph that Collective and Montblanc came up with drew on the sportier design cues from that stopwatch, including the colors, finishing techniques, and the case material (robust stainless steel, of course). The end result is a chronograph that has many key vintage inspired design elements that are core to Montblanc and Mi...

Lorier Updates their Hydra and Hyperion Lines with New Watches Featuring the Miyota 9075 “Flyer” GMT Caliber

A few years ago, one of the most discussed topics on watch forums, Instagram, and indeed in the Worn & Wound office, was the huge opportunity and desire among enthusiasts for a new crop of affordable GMTs with local jumping hour capability. For a time, it seemed that small watch brands could not keep up with demand for so-called “caller” GMTs with independently set 24 hour hands, but these watches are in fact massively inconvenient for travel, even though, in most cases, they were marketed and sold as watches tailor made for crossing time zones. A watch with an hour hand that reads local time and can be jumped quickly without hacking the movement is the ultimate in terms of travel functionality (with or without the ability to track home time, in my opinion), and there was a time not too long ago where it was thought that a watch with this feature deployed by microbrands in watches under $1,000 might be nothing less than a paradigm shift in the hobby. Well, we’re fully there, folks. The Miyota 9075 exists, and has been popping up in new watches from some of our favorite small brands for the better part of a year, and now Lorier has dropped it into a pair of GMT equipped watches, finally making them the dedicated travel companions many hoped they could be.  The Hyperion is what Lorier describes as “the archetypal GMT,” fitting a well established mold of classic travel watches by Rolex and others. It has deep vintage vibes, with a red and blue 24 hour bezel, gilt a...
