Introducing: The Zenith G.F.J. Calibre 135 Double Signed With Naoya Hida & Co.

Zenith’s caliber 135 continues its revival within the brand’s modern lineup with a new version. After the restored vintage-powered editions from 2022 and the following G.F.J. releases in 2025 and 2026, the brand now adds a special, limited collaboration with Naoya Hida to the collection. This time, the focus shifts toward Japanese independent watchmaking. The […] Visit Introducing: The Zenith G.F.J. Calibre 135 Double Signed With Naoya Hida & Co. to read the full article.

Introducing: The Seiko Astron GPS Solar Dual-Time Chronograph In Crystal Green And Crystal Pink Summer “Flavors”

Shortly after Seiko released four revamped Astron GPS Solar Dual-Time Chronographs for its 145th anniversary, the Japanese brand drops two fresh new summer “flavors.” No, they’re not pistachio and raspberry ice cream —although, come to think of it, matcha (green tea) and sakura (cherry blossom) ice cream would make more sense — but instead, Crystal […] Visit Introducing: The Seiko Astron GPS Solar Dual-Time Chronograph In Crystal Green And Crystal Pink Summer “Flavors” to read the full article.

First Look – The Double-Signed Zenith G.F.J. Calibre 135 with Naoya Hida & Co.

When Zenith, celebrating its 160th Anniversary, revived the Calibre 135 in 2025 with the launch of the G.F.J. collection, the manufacture brought back one of the most important precision movements, a calibre that dominated observatory chronometry competitions throughout the 1950s and remains the most awarded movement of its kind. Taking the story in an unexpected […]

Introducing: The Zenith G.F.J. Calibre 135 Double Signed with Naoya Hida & Co

What We Know Today, Zenith introduces a new "Double Signed" program for its Calibre 135-powered G.F.J. collection, and its first entry in this series is a collaboration with a Japanese independent that might not require all that much introduction around these parts—Naoya Hida. The evolution of the G.F.J. line has not taken all that long, with its origins starting in 2022 with the Zenith Caliber 135 Observatoire Limited Edition, where ten Calibre 135 movements from the 50s were restored by Kari Voutilainen and introduced in watches done as a triple collaboration between Zenith, Voutilainen, and auction house Phillips. Just three years later, the Calibre 135 was revived as a modern caliber for a line called the G.F.J. (after Zenith's founder Georges Favre Jacot). In just a little over a year, we've seen three small runs of this watch introduced in different stone-dial and metal combinations—platinum with a lapis lazuli dial, tantalum with an onyx dial, and an upcoming yellow-gold GFJ with a bloodstone dial. In the meantime, this new Double Signed concept with Naoya Hida takes the G.F.J. in a very different visual direction. The hefty 39.15mm platinum case, with a thickness of 10.5mm and a compact lug-to-lug of 45.75mm, remains the same as other G.F.J. models. But that dial is unabashedly Naoya Hida, constructed out of solid silver with the distinctive hand engraving coming from the hand of master engraver Keisuke Kano, the man responsible for the hand engraving across al...

Insight: the Compliant Mechanism Inside the Patek Philippe Celestial 6105G SJX Watches
Patek Philippe Celestial 6105G Jun 2, 2026

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 ...

Introducing: The Aria Manufacture Chronometer From Formex Hodinkee

Introducing: The Aria Manufacture Chronometer From Formex

What We Know The last time I covered something from Formex was over a year ago, when the brand released a highly finished, full-ceramic sports watch, complete with a ceramic bracelet and even a ceramic micro-adjust clasp, at an unrivaled price point. Today, the brand continues its upmarket trend with a brand-new watch design called the Aria. The Aria takes the form of a broad, integrated-bracelet design in full grade 5 titanium. The 40mm case feels broader than normal, thanks to an impressively thin case height of 6.9mm, even though the lug-to-lug is still quite reasonable at 45.45mm. While the silhouette gives a smooth look, there's quite a bit of contrasting finishing going on here, with brushing of the titanium case and bracelet links done entirely by hand. Though the styling certainly leans towards its identity as a bold sports watch, there's a lot of subtlety in the design, for example, with the individual bracelet links being slightly curved or the extra dimensionality of the layer of titanium peeking out from each link's milled-out spaces. The clasp includes Formex's proprietary micro-adjust system, which provides extra space on both sides of the bracelet by pulling or pushing each side. There are three dials for the Aria: "Selva Green," "Ardesia Grey," and "Denso Blue." All three have a certain muted look to the hue, matching the slightly darker nature of titanium. Dimensionality is achieved through contrasting indices in rose-gold coloring, set on applied raised p...

Introducing: Oris Celebrates Its Birthday With The 2026 Hölstein Edition Hodinkee

Introducing: Oris Celebrates Its Birthday With The 2026 Hölstein Edition

What We Know Every year on June 1, Oris celebrates the founding of its brand by releasing watches named after its hometown. This time, they're doing so with 250 numbered pieces based on the brand's new Artelier watch. The new version features small seconds, a 120-hour power reserve, the Caliber 401 movement, and an interesting retro-futuristic style. The new Oris Hölstein Edition 2026 has a stainless steel case measuring 39.5mm by 11.1mm, a 45.5mm lug-to-lug, and 30m water resistance. The dial is light grey with a subtle fumé effect from its shape, with a brighter subsidiary seconds dial in a mirror finish and a small red seconds hand. That silver, domed dial and claw-style hour markers make the watch feel a bit like a throwback to the late 1960s, but with modern specifications. The hour and minute hands have Super-LumiNova. As a bonus, the movement (while not COSC-certified) has an accuracy of 3/+5 seconds per day and is highly anti-magnetic. It's also automatic winding. The caseback uses a special laser treatment that engraves the Oris Bear, features the words "Hölstein Edition 2026," and produces a mirror-like, iridescent rainbow finish. To steal the description from one of the greatest haircuts known to man, it's business in the front and party in the back. The watch retails for CHF 3,800. What We Think Oris has been doing these limited editions, as far as I can tell, since 2020, and each one has been anything but traditional. Obviously, the Oris bear often plays a ...

Kollokium Introduces the Projekt 02 Variant C Worn & Wound

Kollokium Introduces the Projekt 02 Variant C

In the span of just a few short years, Kollokium has gone from a nearly secret insider side project with a hard to discern future to a fully fledged brand. When the Projekt 01 first came on the scene, it was a bit of a mystery to most what the founders (Manuel Emch, Barth Nussbaumer, and Amr Sindi) had planned, or even if they had planned anything at all. There was a one-off quality to that initial drop that seemed to communicate it could all be abandoned at any moment.  Honestly, the watch industry probably needs a little more of that energy – watches that exist outside of a business plan and represent an artistic vision more than a marketing ploy. But credit to Kollokium for being smart about the way they’ve managed expectations and continue to move the ball forward across several subsequent releases since the Projekt 01. In addition to new colorways for that original design, they’ve introduced an entirely watch (not so creatively called the Projekt 02) that builds on the design language introduced in the first piece and deepens the complexity pretty significantly. They’ve just announced the latest Projekt 02, Variant C, and it’s the latest chance for collectors to get in on one of the most interesting new designs in indie watchmaking.  As a refresher, the Projekt 02 is defined by a dial built on a series of stacked plates (over 60 of them) in different shapes and sizes that when fully assembled resemble a three dimensional topographical map. The terrain of t...
