Serica Introduces the 8315-3 Golden Green Travel Chronometer

French microbrand Serica has toiled since 2019 to create an aesthetic that makes their watches instantly recognizable—rounded design elements with precise proportions, even wildly varying models like their field watch, diver, and stadium-shaped Parade contain unifying hallmarks: carefully considered dial balance, 1970s-esque styling, and prominent bezel designs all signal a Serica timepiece. Over the past seven years, they’ve continued to refine their watches from a mechanical standpoint, too, introducing complications and added robustness to withstand tool watch duties. The 8315 line of GMT models is perhaps their most function-forward design, first debuting in 2022. Like most Serica watches, it favors a cleanly balanced dial, meaning no date function—ideal for a travel watch, which is the intended use of the 8315, earning it the “Travel Chronometer” name. Now, Serica unveils a slick new colorway for the popular model: Golden Green.  The 8315-3 Golden Green doesn’t purport to be a grand deviation from the Travel Chronometer formula. In fact, it bears the same internals and basic design as its line-mates, primarily the Swiss chronometer-certified Soprod C125 automatic movement, which allows for 42 hours of power reserve and 200 meters of water resistance. This movement powers the GMT hand and “caller” GMT function. This gives it a simpler use case than the more complicated local jumping “flyer” GMT seen in watches like the Tudor Black Bay GMT; basicall...

Introducing: Fredrique Constant Manufacture Classic Perpetual Calendar Burgundy Limited Edition (Live Pics)

What We Know Last year, Frederique Constant released its classic perpetual calendar with a new movement, the FC-776, and eighteen months later, the brand is releasing a burgundy edition of its Manufacture Classic Perpetual Calendar, limited to 100 pieces. As Mark wrote when the previous edition was released right before last year's Watches and Wonders, the watch "has been one of if not the premiere affordable mechanical perpetual calendar on the market," and with the burgundy edition, the brand is offering a limited edition option to the collection. The polished stainless steel case measures 40mm by 12.25mm and has an anti-reflective convex sapphire crystal, 50 meters of water resistance, and an engraved case back carrying the individual edition number. The sunray-finished dial shifts from deep wine tones to brighter reflections, with a Côtes de Genève pattern on the counters. The day sits at 9 o'clock, the date at 3 o'clock, and the month and leap year at 12 o'clock. The moonphase at 6 o'clock runs against a midnight-blue background with laser-engraved stars. A chemin de fer minute track, applied faceted hour markers, and polished hands, and the fluted onion crown complete the dial. The Manufacture Classic Perpetual Calendar Burgundy Limited Edition, comes on a black alligator strap with a folding buckle and includes a second strap in burgundy alligator with an easy-open deployment clasp. It is priced at $12,995, limited to 100 pieces, and is available now. What We Thin...

In Partnership - From The Source : NORQAIN's Ben Küffer Talks Us Through the Expanded Wild ONE Collection

Challenging conventions is part of NORQAIN's DNA. For CEO Ben Küffer, that aim to "redefine what a Swiss mechanical sports watch could be" has been instrumental to the brand's success. For its latest release, the family-owned Swiss brand announced three new models in a first for the brand: grade 5 titanium. The Wild ONE Skeleton Titanium 39mm and 42mm reimagine the brand's signature sports watch, incorporating grade 5 titanium into the watch's top plate with the bottom retaining NORQAIN's signature NORTEQ carbon-fiber-composite.The result is a rich visual contrast and lightweight construction. "Titanium certainly has a future within NORQAIN," Küffer says, "but only where it adds something meaningful to the design and performance of the watch." Each possesses a distinct identity, with the 39mm—limited to 400 pieces—opting for a grey palette based on titanium's muted character, featuring light yellow dial accents and Super-LumiNova for technical performance and legibility. The 42mm, by contrast, opts for a slightly bolder coloring with mint green details for a bolder visual presence. Both are powered by the skeletonized in-house NK26/1 automatic movement, a COSC-certified chronometer with a 65-hour power reserve. The star of the new collection, however, is the all-new Wild ONE Meteorite Titanium 42mm. The Meteorite takes the brand's flagship watch and incorporates Grade 5 titanium and an anthracite iron meteorite dial, combining contemporary high-tech design with ancie...

In-Depth: 200 Odd Years of Hacking Tourbillons

Conventional wisdom holds that stopping a tourbillon for precise time setting — “hacking” in watchmaking parlance — is a difficult endeavor given the constant rotation of the cage. The hacking tourbillon wristwatch didn’t arrive until 2008, courtesy of the A. Lange & Söhne Cabaret. In fact, hacking of any sort remained a rarity until the last few decades — ironic, since the primary function of the seconds hand has arguably evolved from a way to assess accuracy into an indicator that a watch is running. Some brands are still in the process of adding stop-seconds features to their basic calibres, and hacking remains scarcer still in wristwatch tourbillons, appearing with regularity only in the last two decades. But building for the waistcoat pocket, historical watchmakers have been stopping tourbillons for almost as long as they’ve been building them, and developed a number of solutions for this problem along the way, each stopping the tourbillon, or merely the seconds, in a different way. Breguet – stopping the seconds without stopping the watch Almost 225 years ago to the year, the French Ministry of the Interior granted Abraham-Louis Breguet (1747 – 1823) a patent for his most famous creation, the tourbillon, a clever way to improve a watch’s marks during accuracy testing. For a mechanical watch to keep the same time across all vertical positions, the “balance complete” — comprised of the balance, staff, roller, collet and balance spring — mu...

H. Moser & Cie.’s Off-Grid Bares All SJX Watches
Breitling Aerospace debuted more than Sep 23, 2026

H. Moser & Cie.’s Off-Grid Bares All

Following last year’s Streamliner Alpine Mechanics Edition made for the Alpine F1 team, H. Moser & Cie has just released its second smartwatch, this time with a unique take on the genre. The Off-Grid offers a streamlined set of programmed complications designed to occupy in the space between a mechanical watch and a smartwatch. In doing so, the Off-Grid eschews common functions like health tracking and notifications, allowing its full feature set to be accessed with or without a smartphone connection. The offline theme explains its most unusual complication, a built-in dictionary of 10 words in each of 21 different languages. Initial thoughts At first glance, the 1980s-style ana-digi display may feel more at home in a G-Shock or Seiko ‘Arnie’ than a Swiss luxury watch, though Moser is hardly the first Swiss brand to give the format a go. The Breitling Aerospace debuted more than 40 years ago, and Omega later introduced the ana-digi Speedmaster X-33 in 1998. But unlike the aforementioned, Moser’s choice to put the module on show beneath a semi-open-worked dial is a unique approach and reveals the brand’s mechanical watchmaking instincts. With the Off-Grid, Moser is trying to find the middle ground between mechanical and electronic watchmaking that offers the benefits of both worlds but without all the downsides — like constant notifications and fast-draining batteries. The “Off-Grid” moniker sums up the effort, both in terms of its autonomy and its conceptua...

Insight: Screw-Down Showdown SJX Watches
Omega Speedmaster Moonwatch Sep 22, 2026

Insight: Screw-Down Showdown

Mechanical movements attract most of the technical interest in watchmaking, but considerable engineering also goes into keeping them dry. For an everyday watch, the waterproof construction of the case and crown is central to its reliability, yet the way these components keep water out is often misunderstood. Screw-down crowns and case backs are widely regarded as the best way to seal a watch. But the choice is not always straightforward. On a hand-wound watch, for example, a screw-down crown must be unscrewed and tightened regularly, adding an extra step to winding and potentially compromising the threads. The Omega Speedmaster Moonwatch, on the other hand, features a conventional crown and is rated to 50 m. Even so, some owners remain wary of exposing it to more than an occasional splash. So the question is, how much protection can a conventional crown provide, and what does a screw-down construction add? To understand the distinction, we take a closer look at the crown, its tube and the gaskets that form the seal. As a disclaimer, this discussion concerns modern watches with seals in good condition; vintage watches and those long overdue for service should be checked for waterproofness prior to contact with water. A common misconception The actual waterproofness of a joint relates to the uniformity of the seal pressure. In this case, “waterproofness” is used broadly as the ability of a mechanical joint to keep water from seeping in under normal functioning conditions...

Introducing the Apiar Carbon1.0 OG

Think about where we are in watchmaking in 2026. You could argue, pretty reasonably I think, that the problem of chronometry has basically been solved. We have access to mechanical watches that are accurate to seconds per month, and quartz watches that are accurate to seconds per year. There are advancements around the edges (Grand Seiko’s new U.F.A. movement comes to mind, the most accurate watch powered by a mainspring, accurate to 20 seconds per year), but it’s hard to imagine an advancement in timekeeping at this point that would actually be meaningful in our daily lives. For movement geeks, sure, shaving off seconds here and there will always be a fun new development, but for many we’ve reached a point of diminishing returns, where all that really matters are bragging rights by the brands (and those matter a lot – big marketing campaigns are built around them).  So where do the advancements come from in the years ahead? Many people with a lot more experience in this industry than me have discussed materials science as the next big step for watch brands, and we’ve certainly seen a lot of alternative materials used in cases and movements over the last few years. Once you go beyond the traditional steel, titanium, and precious metals that watch cases are normally made from, you open yourself up to manufacturing and creative options that are typically encountered across other industries, like the aerospace sector and medical manufacturing.  The UK based brand ...

Timex Celestial Opulence Automatic TW2T86300 Review: Beautiful Design, but Mind the Scratches

When shopping for a women’s automatic watch, finding something that steps outside of traditional designs without becoming overly complicated can be a challenge. The Timex Celestial Opulence Automatic (TW2T86300) is a watch that attempts to strike that balance. It draws inspiration from the night sky and pairs it with a traditional mechanical movement.   However, as many owners quickly discover, its eye-catching design comes with a practical drawback that you should be aware of before making it your daily timepiece. The Appeal of the Celestial Opulence Design Let’s talk about the best part of the Timex TW2T86300: the way it looks. I am really drawn to the design of this watch, specifically the combination of black and gold. The watch features a gold-tone stainless steel case paired with a deep black dial. It’s a classic color combination that works with almost everything in my wardrobe. Whether I’m just wearing jeans and a t-shirt or dressing up a little bit for an evening out, the black and gold colorway manages to fit right in. It looks rich and warm, but the black keeps it grounded so it doesn’t look cheap or overly bright. The dial is where the “Celestial” name comes into play. It has a night sky theme, featuring small stars and Swarovski crystals acting as the hour markers. I usually don’t like crystals on watches because they can look tacky, but here they are small enough that they just look like distant stars catching the light. Another cool detail ...

Frederique Constant Highlife Moonphase Date Sep 2, 2026

Introducing: Frederique Constant Highlife Moonphase Date And Classics Moneta Handwinding

What We Know At Geneva Watch Days this year, Frederique Constant introduces two new references that continue to build on the momentum the brand generated at Watches and Wonders. The Highlife Moonphase Date adds a moonphase complication to the Highlife collection; the Classics Moneta Handwinding is the first mechanical movement in a collection that launched in 2024 with a quartz movement and added a solar version earlier this year. Together, the two references display the range of what the manufacture builds in-house, from a complicated moonphase module to a hand-wound caliber developed exclusively for the brand. The Highlife Moonphase Date measures 39mm and comes in two dial colors. The rosé champagne dial uses a sunray finish that radiates outward from the moonphase window at 6 o'clock rather than from the center, with gold and copper tones set against a blue moon disc. The night blue dial uses a lighter sunray finish closer in tone to its own moon disc, with a red "31" marking the final day of longer months.  The moon disc is rendered with grey shading and surface relief rather than a flat metallic disc. Both versions use applied, mirror-polished, lume-filled indexes and hands. By comparison, the Classics Moneta Handwinding measures 38.5mm and comes in a single dial color: a smoked salmon-tone gradient that darkens to black at the edges, with applied mirror-polished hour markers, two dauphine hands, and a small seconds sub-dial at 6 o'clock. The Highlife Moonphase Date...
