INTRODUCING: The Audemars Piguet 2021 Royal Oak Chronographs powered by in-house AP caliber 4401

We all know the “Holy Trinity” manufacturers can be called out at times for being on the slower side when it comes to product evolution. To be honest, that’s for a good reason, too. The pursuit towards perfection has to be careful and calculated, and each of the brands have to ensure their watches live … ContinuedThe post INTRODUCING: The Audemars Piguet 2021 Royal Oak Chronographs powered by in-house AP caliber 4401 appeared first on Time+Tide Watches.

Seiko Remembers Legendary Japanese Explorer with Prospex 6105 Remakes

Legendary for being the first man to reach the North Pole solo, Naomi Uemura (1941-1984) was an explorer who notched up several expeditionary feats before disappearing in 1984. Amongst his achievements was a solo, sled-dog run from Greenland to Alaska in 1976 – a two-year, 12,500 km journey – in preparation for climbing Vinson Massif, Antarctica’s highest peak. It was on this trip that Uemura wore a Seiko ref. 6105, the “turtle” diver launched in 1970 that has since become one of Seiko’s best known dive watches thanks to the distinctive case shape. Uemura disappeared in winter 1984 whilst descending the Denali – after successfully reaching the peak – never to be seen again. February 2020 would be his 80th birthday had he lived. To commemorate his life, Seiko has introduced the Prospex The 1970’s Diver’s Modern Re-interpretation modelled on the ref. 6105 worn by Uemura and available in two variants, the limited-edition SLA049 and the regular-production SLA051. The Seiko ref. 6105 of 1970 worn by Uemura during his 1976 solo sled-dog run Initial thoughts Seiko loves limited editions – a trio of Prospex models for its 140th anniversary was just announced – and the limited editions are often facelifts of existing models. To an extent, that remains true. The new SLA049 looks very similar to the SPB183 – nicknamed the “Captain Willard” by enthusiasts after the character who wore on in Apocalypse Now – that was released late last year. Like the...

Seiko Introduces the Diver’s Watch 55th Anniversary “62MAS” and “6105”

Seiko is marking the 55th anniversary of its first diver’s watch with remakes – yet again. The Prospex 1965 Diver’s Re-creation SLA043 modelled on the 62MAS 6217, while the Prospex 1970 Diver’s Modern Re-interpretation SPB183 takes its cues from the 6105-8110. Initial thoughts Seiko is certainly not short on diver’s watches: it introduced the 55th anniversary trilogy in March, as well as a green-dial LX diver a few months later. This pair feels like two watches too many, especially since they aren’t that different from watches launched before. 1970 Diver’s Modern Re-interpretation SPB183J1 (left), and 1965 Diver’s Re-creation SLA043J1 It’s a given that both possess all of the intrinsic appeal of Seiko dive watches – solid construction, excellent case finishing, and a robust movement. The two watches also enjoy strong historical legitimacy given Seiko’s immense track record in dive watches. But not only does there seem to be too many Seiko limited editions, both are not quite as afforably priced as Seiko dive watches once were. They are still reasonably priced, but no longer as compelling. 62MAS The 1965 Diver’s Re-creation SLA043 is a remake of the first-ever Seiko dive watch, the 6217 “62MAS” of 1965. Like earlier 62MAS remakes, this is larger than the original at 39.9 mm in diameter. Notably, it is slimmer than the remake from the diver’s watch trilogy launched earlier in the year, because this is powered by the 8L35 running at 4 H...

An Omega fan responds to the release of the Omega Speedmaster Caliber 321 (and addresses the 20K elephant in the room)

Putting on my Speedmaster Professional 50th anniversary this morning, I couldn’t help but reflect and smile on the huge announcement from Omega. The decade has just begun and Omega dropped a bombshell with the announcement of the Omega Speedmaster Caliber 321 in stainless steel.  By now, you would have read that this particular watch was … ContinuedThe post An Omega fan responds to the release of the Omega Speedmaster Caliber 321 (and addresses the 20K elephant in the room) appeared first on Time+Tide Watches.

Seiko SLA033 Prospex Diver - A Tribute To The 6105

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.

New: Omega re-introduces the Caliber 321

Now, more than 50 years after the last Calibre 321 was produced, Omega is bringing the iconic movement back. Known forRead More

Hands-On: The Patek Philippe Celestial Ref. 6105G (Plus Technical In-Depth)

We're on the eve of one of Patek Philippe's biggest events every few years: the October 2nd to the 18th presentation of the brand's Watch Art Grand Exhibition in Milan. On Monday, I'll be flying there for a preview of the exhibition, so stay tuned for stories from that trip coming in the near future. Another story, which has been waiting in the wings and in progress for some time now, was a hands-on look at two of the most surprising (and potentially divisive) releases from Patek this year: the Cubitus perpetual calendar and the Celestial ref. 6105G. While all eyes were on the Nautilus's 50th anniversary, I thought Patek Philippe had a very interesting Watches & Wonders, at least from the perspective of bold releases and brand strategy. Truthfully, they could have done just about anything with the Nautilus, and those lucky enough to get a watch would have been happy. The Celestial alone was a wristwatch with a complication only four other brands have created. But just take a look at the two watches above and the two below. While I didn't get to see the ref. 7047G in person, it raised eyebrows for the very unusual blue tire tread-style dial (à la ref. 6007G) and remarkably strong orange accents and luminous hands and dial placed on a minute repeater that retails north of $570,000. It was perhaps so aesthetically surprising that it distracted people from the fact that Patek was honoring its past with a Calatrava-cased minute repeater reminiscent of the unique ref. 3652 and ...

Insight: the Compliant Mechanism Inside the Patek Philippe Celestial 6105G

The standout piece from Patek Philippe at Watches & Wonders 2026 was certainly the Celestial Sunrise and Sunset Ref. 6105G-001. The astronomy-oriented watch was a decade in the making and compared to its more conservative predecessor, the ref. 6102, the new model benefits from a complete makeover, both aesthetically and mechanically.  Hidden within the 47 mm white gold case is an unusual component that didn’t get the attention it deserved at launch: a butterfly-shaped compliant cam-and-rack mechanism. The system is used for the sunrise/sunset indicators and proves Patek Philippe’s almost savant-like mastery of compliant micro-mechanics.  The Celestial ref. 6105 is pictured showing a sunrise of around 8 AM, and a sunset time of about 7 PM. Note the date ring pulls double duty as the sunrise/sunset scale. Fixing something that may be broken Although still quite rare compared to other complications, there are more sunrise/sunset watches on the market than seemingly ever before. They mostly follow the same basic construction: a cam that works with a follower. As the year progresses, the cam slowly turns, displacing the follower. In pairs, such systems are used to show both the sunrise and sunset times, which synchronously vary throughout the year.  So why fix something that doesn’t appear to be broken? Or more specifically, why use an elaborate compliant system when a basic cam and follower is a fixture in classical watchmaking? European patent EP3740821B1 granted to ...

Patek Philippe’s Celestial Ref. 6105G Blasts Off

Patek Philippe updates its star chart “Grand Complication” for the third time with the Celestial Sunrise Sunset Ref. 6105G. The ref. 6105G adds the time of sunrise and sunset – cleverly integrated into the date scale – and a daring new design with a formidable, space-age lug-less case in white gold that’s 47 mm across. The ref. 6105G also introduces a novel way to account for the transition between summer and winter time, adding a corrector that shifts the sunrise and sunset scales, solving a significant shortcoming of astronomical watches for users in Europe and the Americas. Initial thoughts I’ve long thought that Patek Philippe’s greatest strength, other than its massive industrial investments, was its remarkable design diversity. Today brands seem to pursue a unified design language across all of their watches. And while this result is a strong visual identity for the brand, it is extremely limiting. Patek Philippe has no such limits, and the brand has about two dozen different case styles in the current collection, and hundreds in its back catalog. While this leads to its fair share of design misses, at least to my sensibilities, it can also lead to striking successes. I’m sure many will disagree, but I see the new Celestial as the latter. A wristwatch with the time of sunrise and sunset is long overdue from Patek Philippe, and this watch adds the ability to adjust those indications to account for daylight savings time. This addresses the complication...

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...

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, ...

Introducing: Atelier de Chronométrie's New Chronograph Caliber Is A Stunning Return To The Past

What We Know If you're following artisanal watchmaking with all the flash and hype of the independent space, you're forgiven for missing Barcelona-based Atelier de Chronométrie. Their watches don't often show up on social media, largely because they are entirely bespoke, one-off commissions based on the various architectures they offer. But we've been covering them since 2016, and the product (and potentially their clients' tastes) has gotten better and better. Outstanding, in fact. That's how I'd frame their new AdC16, the company's first two-counter chronograph. If you don't like the design, that's fine—you can customize it however you like—but top-down, movement-to-specs, the watch is really attractive to a vintage lover like myself. Atelier de Chronométrie allows customization of the case and dial, as well as finishing on the movement (a variation of which they are going to share soon, based on this movement), but in this case, they've made a really nice, compact, 36mm Calatrava-style case that is reminiscent (with the dial) of a Vacheron Constantin 4072. The case is two-tone yellow gold and steel and has a black galvanic gilt-style dial (though not actually done the original way, as the press release states; more likely pad-printed), with yellow gold applied markers and hands. The kicker is really the movement. The base design is the venerable Valjoux 23, but they've redesigned the shape of several bridges and levers while trying to keep the entire gear train fe...

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...

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...
