Introducing: Three New Patek Philippe Nautilus References Celebrating The Watch’s 50th Anniversary

The Patek Philippe Nautilus returns in three new references that lean into the model’s archetypal design. They feature thin cases, clean dials, and a familiar architecture to celebrate 50 years of the Patek Philippe Nautilus. All three use the ultra-thin caliber 240, now with a commemorative mini-rotor engraving that pays homage to the model’s 1976 […] Visit Introducing: Three New Patek Philippe Nautilus References Celebrating The Watch’s 50th Anniversary to read the full article.

With the introduction of the Cubitus collection in late 2024, Patek Philippe established a new design language built around a square case with rounded corners and an integrated, sporty-leaning aesthetic.

The only sense of nature you can experience when spending days on end in Geneva’s Palexpo event center is by handling Grand Seiko novelties. Yes, we sometimes joke about the plethora of nature-inspired dial designs that the Japanese brand releases. Still, they’re most welcome during Watches and Wonders.

TAG Heuer Rethinks the Chronograph SJX Watches

TAG Heuer Rethinks the Chronograph

Sure to be among the most talked-about releases of Watches & Wonders, TAG Heuer has just unveiled the Monaco Evergraph. The openworked Monaco marks the debut of the calibre TH-80, one of the most advanced chronograph movements on the market. The Evergraph’s movement is notable for several reasons, but the most surprising is the use of an innovative compliant structure to simplify the chronograph mechanisms. Initial thoughts Beginning with the relaunch of the TH-Carbonspring last year, TAG Heuer has been on something of a road to redemption. Not long ago it seemed like the brand’s brightest days might be behind it, but the Evergraph provides further evidence that TAG Heuer has been retooling to become a new leader in technical innovation. The famous Breitling-Heuer-Buren Calibre 11 - one of the first automatic chronograph movements to hit the market back in 1969 - debuted in a Monaco, and so it’s fitting that the new TH-80 movement is first glimpsed through the transparent dial of the Monaco Evergraph. In more ways than one, the Evergraph pays proper hommage to original Heuer Monaco while remaining decidedly future-oriented.  It is also great to see the TH-Carbonspring literally front and centre on the dial side, proof that TAG Heuer is finally delivering on the promise of carbon hairspring industrialisation.  Even before digressing into the distinctive mechanics of the new cal. TH80-00, any chronograph aficionado will greatly appreciate the particular crown and...

Watches & Wonders: Grand Seiko Finally Gives Us a Medium Sized Dive Watch, and it Includes a Spring Drive Powered U.F.A. Movement

If you were take a poll of Grand Seiko enthusiasts and collectors to ask them what they thought was missing from the brand’s catalog, I have a feeling a significant portion of respondents would tell you the same thing: a great dive watch. Grand Seiko has, of course, been making divers for years, and a lot of them have been objectively outstanding and well liked by certain pockets of the Grand Seiko community. But they’ve never had a diver that’s really caught fire in the way that something like the Snowflake has – there’s no icon in their dive watch range. I think most would agree that this is at least in part because to this point the brand’s dive watches have always been on the chunky side, and not really a viable competitor to the Submariners and Seamasters of the world in terms of their wearability.  Grand Seiko seeks to change that at Watches & Wonders this year, with the rather ambitious release of the new Spring Drive U.F.A. Ushio 300 Diver. This new 40.8mm High-Intensity Titanium dive watch uses a new Spring Drive movement featuring the same tech as last year’s 9RB2 Spring Drive caliber, which boasts an accuracy rate of plus or minus 20 seconds per year.  There are really two notable things about this watch. First, there’s the movement, Caliber 9RB1, which has the same U.F.A (Ultra Fine Accuracy) designation as the 9RB2 introduced last year. The 20 second annual accuracy rate is, according to Grand Seiko, the most accurate wristwatch movement powe...

Open Or Closed? The Gerald Charles Masterlink Perpetual Calendar Gives You A Choice

Okay, that subtitle is half right. The Masterlink design, with its typical “smile” at 6 o’clock, is not new. But instead of trying to fit a traditional round QP movement into the case, Gerald Charles chose to build a shaped one. The Gerald Charles Masterlink Perpetual Calendar is so handsome that, apart from a closed-dial […] Visit Open Or Closed?

Gagà Laboratorio’s New Aqualab Pulls Off A Tricky Design Brief

When I heard Gagà Laboratorio was launching its first dive watch, the Aqualab, I was skeptical. The brand’s distinct identity made me question how it would translate into a sportier, tool-oriented direction. That’s a testament to the uniqueness of its design language, not a criticism of its existing watches. The Labormatic, for example, always struck […] Visit Gagà Laboratorio’s New Aqualab Pulls Off A Tricky Design Brief to read the full article.

Hands-On With The IWC Ingenieur Perpetual Calendar: A Brilliant New Evolution

The IWC Ingenieur Perpetual Calendar brings one of the brand’s most celebrated complications into its modern integrated sports watch design for the very first time. I take a closer look at what makes this latest evolution of the Ingenieur such a compelling release. What We Love: Compact proportions for a sports watch with Kurt-Klaus’s perpetual calendar design Beautifully executed case and dial finishing Stainless steel makes it more wearable and accessible What We Don’t: No micro-adjustment system on the bracelet clasp Limited strap versatility due to the integrated bracelet design No precious metal option at launch for those wanting a more luxurious take Overall Rating: 8.8/10 Value for Money: 8.5/10 Wearability: 8.5/10 Design: 9/10 Build Quality: 9/10 The Ingenieur has always been one of IWC’s most compelling designs, blending Gérald Genta’s signature aesthetic codes with the brand’s own sporty heritage and technical edge. I’ve been fortunate enough to review quite a few models from the Ingenieur range, which gives a good sense of how the overall collection sits across various sizes and complications. During Watches & Wonders 2025, arguably, one of the biggest shifts to the Ingenieur collection in modern times. The Swiss luxury watch manufacturer presented the Ingenieur in a 41.6mm case, with none other than a perpetual calendar complication sitting inside. The IWC Ingenieur Perpetual Calendar is the first of its kind, released during Watches & Wonder...

John M. Flaux Presents the Architectural La Villa d’hOro Clock

ACHI member and clockmaker John-Mikaël Flaux unveils the first clock in a new series, the Renaissance-inspired La Villa d’hOro. Fashioned as a tribute to the romantic city of Venice, the clock has an exposed movement and three dials, making it a rather practical piece of horological art.  Initial thoughts Table clocks represent a niche category, even within the already niche realm of mechanical clocks. They lack the both the sobriety of large standing clocks and the convenient portability of watches - whether built for the pocket or the wrist. That said, this middle ground arguably makes them more attractive to a certain type of collector. Many modern artisanal clock producers take inspiration from science-fiction, popular culture or the automobile world. John-Mikaël Flaux went for a very different aesthetic with his La Villa d’hOro. Taking from his own experience exploring cities, the artisanal clockmaker decided to launch a small series of city and architecture inspired clocks, the Villa Tempus series.  The first model, the La Villa d’hOro, takes its inspiration from the insular Italian city of Venice. Mr Flaux cites the landmark Doge Palace as the core architectural inspiration. The idea behind the La Villa d’hOro is to be reminiscent of Venice without actually emulating any specific part or building of the floating city.  In many ways the La Villa d’hOro manages to capture the old world charm Venice, which has been mostly kept almost intact to this day...
