Reinventing The Micro-Rotor: Renaud Tixier Makes A Mechanically Innovative Debut

Some 25 kilometers north of Geneva, on the shore of the city’s eponymous lake, lies the town of Nyon. This is the place that Renaud Tixier, the latest Swiss independent watch brand launching today, calls its home. It’s the latest collaborative effort between Dominique Renaud - the renowned watchmaker and co-founder of Renaud & Papi […] Visit Reinventing The Micro-Rotor: Renaud Tixier Makes A Mechanically Innovative Debut to read the full article.

Revolution and Sinn Team Up for a First of its Kind 155 Chronograph Worn & Wound
Sinn Team Up Mar 18, 2024

Revolution and Sinn Team Up for a First of its Kind 155 Chronograph

Our friends at Revolution have launched their second limited edition collaboration with Sinn, following up on 2019’s 155 Bundeswehr “Dark Star,” a collaborative effort with both The Rake and Revolution publications. Here we have another 155, this time in a notably darker, and tougher configuration, but still paying tribute to the very roots of the German watch brand. The 155 chronograph, for many Sinn collectors, represents the true beginnings of the brand, and this release captures that spirit while adding some of the contemporary twists you’d expect from a collaboration partner like Revolution. It’s all very enthusiast focused, and should really speak to hardcore Sinn fans.  Before we get into the details on the new release, an introduction to the 155 is probably in order to fully contextualize the limited edition. Beginning in 1967, the 155 Bundeswehr chronograph was made exclusively for the West German Federal Defense Force. Beginning in the 1980s, Helmut Sinn began selling issued Bundeswehr watches that had been decommissioned under his own brand name. This practice helped to bolster Sinn’s reputation in watch communities that care about military provenance, tool watch history, and classic design, and laid the groundwork for what Sinn would come to represent to many, makers of no-nonsense, practical tools with true military bona fides. The 155 itself is a ruthlessly simple affair, with a two register chronograph layout and bi-directional 60 minute bezel d...

Baltic Launches Limited Edition Hermétique References Inspired by Glaciers Worn & Wound
Baltic Launches Limited Edition Hermétique Mar 14, 2024

Baltic Launches Limited Edition Hermétique References Inspired by Glaciers

Whether you’re thinking of Titanic or the majestic vista of Mont Blanc, there is no denying that glaciers have long held the fascination of the human psyche. In a way, their calming, serene presence belies the danger that can exist on one of these masses of ice – and, in a way, this juxtaposition is a perfect jumping-off point for a watch design. Like, for instance, what Baltic has done with their Hermétique Glacier collection. Coming in both a White and Black reference, the Hermétique Glacier is both meticulously crafted and finely designed to elegantly represent the essence of les glaciers. Starting with the dial, both the White and Black versions draw inspiration from the ethereal beauty of glaciers to create a stamped pattern that emulates the various textures of a glacier’s surface. Super-Luminova® BGW9-coated hour appliques and “syringe” hands ensure effortless readability, even amidst dimly lit environments. Ostensibly a field watch, Baltic reinforces the notion of “form and function” when combining a beautifully designed watch with its 150-meter water resistance, double-domed sapphire crystal, and use of 316L stainless steel for the case. Despite its rugged capabilities, the Hermétique Glacier maintains an elegant profile, with the case measuring a mere 10.8mm in thickness and clocking in at 37mm. The watch runs on a calibre 9039 movement, a self-winding movement with a 42-hour power reserve developed by the Japanese manufacturer Miyota. Various s...

Hands-On: the Nodus x Raven Trailtrekker

“Whoa, this thing is cool” is what I found myself speaking out loud upon opening up the box for the newest collaboration between Nodus Watches and Raven Watches - two forces in the microbrand community that have a solid history of putting out some really great watches. The real question is, what happens when these two team up? Is this the initial meeting of superheros that eventually leads to the Avengers of the watch space? I’m in no place to make that call, but what I can confidently comment about is how this watch looks and feels on the wrist. But like any good saga, we could use a little back story.  Nodus Watches are a team based out of Los Angeles, CA with a focus on providing premium timepieces that are durable and innovative, while supporting the rest of the watch community. Whether you’re attending one of their Intersect events that brings smaller brands and their customers together across the US, or checking out their other collabs as part of their Design Lab, there’s a lot to like about Nodus. Raven Watches is based out of Kansas and their timepieces are inspired by travel, adventure, and photography -- making for rugged, versatile timepieces that are built for the long haul. The inspiration behind the TrailTrekker is the perilous journey that many heartlanders from the midwest made from Kansas to California, the home states of each brand. Let’s take a closer look at this noteworthy collab. Case The 39.5mm case is perfectly proportioned for my 6...

Up Close: Louis Vuitton Voyager Flying Tourbillon Plique-à-Jour SJX Watches
Louis Vuitton Voyager Flying Tourbillon Plique-à-Jour Mar 13, 2024

Up Close: Louis Vuitton Voyager Flying Tourbillon Plique-à-Jour

A watch that exemplifies the ambitious vertical integration of Louis Vuitton’s watch division, the Voyager Flying Tourbillon Poinçon de Genève Plique-à-Jour combines a skeleton tourbillon movement with a plique-à-jour enamel dial. Transparent and akin to stained glass, plique-à-jour enamel is rare in watchmaking, with only a handful of brands having accomplished it. But this specific form on the Voyager tourbillon, which goes without any backing under the dial, is even more uncommon. Because there is no base for the dial, the transparency of both the dial and the movement is maximised. Initial thoughts The original version of this watch, essentially identical but without the enamel dial, was launched in 2016. Louis Vuitton didn’t get much attention as a watchmaker then, though I liked the watch, particularly the slim profile and open-worked movement made by La Fabrique du Temps (LFT). The quality of the watch indicated Louis Vuitton was going places as a watch brand. Louis Vuitton has come a long way since then as a watchmaker. It now boasts several automaton wristwatches, the Rexhep Rexhepi RR01 collaboration, and its own prize for independent watchmakers. Appropriately enough, the Voyager tourbillon has been enhanced, reflecting the substantial expansion and development of LFT since 2016. The movement, dial, and case are all made in-house at LFT, reflecting Louis Vuitton’s impressive manufacture that now rivals some of the most prominent names in haute horlog...

Seiko Presage Cocktail Time Guide

In their relatively short tenure on the international market, Seiko’s Presage “Cocktail Time” watches have already established themselves in the minds of many enthusiasts as one of the watch industry’s very best value prospects in the realm of automatic dress watches - boasting in-house movements, high-end finishing, and the colorful dials that lend them their nicknames, each inspired by concoctions from Japan’s world-famous high-end cocktail bars. Here is a guide to the Seiko “Cocktail Time,” with highlights and milestones from the modern collection. Happy Hour in Japan Seiko served up the first round of its “Cocktail Time” watches exclusively to customers in Japan. The first of these  “JDM” (Japan Domestic Market) models debuted in 2010 and carried the Reference number SARB065. Now discontinued (and accordingly in high demand by collectors), this watch (above) and its siblings, the SARB066 and SARB068, featured 40mm cases in stainless steel, which were fairly thick at 13.3mm high. The movement inside the cases was Seiko’s Caliber 6R15, with bidirectional automatic winding, a 50-hour power reserve, and an impressive resistance to magnetic fields of 4,800 A/m.  Unlike the many Presage models that followed, the originals were not nicknamed after specific cocktail concoctions but simply for different styles: the SARB065 with its ice-blue dial was “Cool,” the SARB066 with a pale, cream-colored dial was “Dry,” and the reddish brown dial of t...

The Case for Quartz Luxury Watches: Featuring F.P. Journe, Grand Seiko, and Accutron

When starting out on a watch journey, one of the first questions to consider is the choice between quartz and automatic watches, with the perception that mechanical watches are "better" and more expensive, while quartz watches are entry-level and lower quality. While this may hold some truth, luxury brands also produce high-end quartz pieces that are equally impressive from a technological standpoint.

It had a good run: Voyager 1 was launched 46 years ago, and captured scientifically important images of Jupiter and Saturn, and famously turned its camera back home to snap the famous “pale blue dot” image of earth. As Voyager 1 left the gravitational pull of the sun, it continued to send data back to NASA, but that stopped sometime in November of last year, and it seems increasingly likely that the probe is simply adrift in space, capping decades of important research. The sheer distance Voyager 1 has traveled (and will continue to travel, whether it’s transmitting data or not) is simply mind blowing, and the longevity of the mission leaves an emotional void among those who care about this kind of research just as much as a scientific one.  A Highly Anticipated New Lens from Sony According to a recent post on sonyalpharumors.com, a new first of its kind lens will s...

Arken Launches their First Limited Edition for British Watchmakers’ Day

As an avid lover of tool watches, there aren’t many brands that have caught my attention in the last few years quite like Arken. Part of the explosion of small independent watch brands coming out of the UK, Arken has been on my mind since the release of their first watch, the Instrumentum, in 2021. The Instrumentum was followed up by the Alterum last year and now Arken is releasing their first-ever limited edition; a new variant of the Alterum inspired by the Year of the Dragon - a popular source of inspiration over the last few months with everyone from Hublot to JLC getting in on the action. In technical terms, the Alterum Year of the Dragon is the same watch we were introduced to last year, and which is now starting to pop up on people’s wrists as delivery gets underway. The Year of the Dragon comes in the same 200m water-resistant 40mm grade 2 titanium case and is equipped with the same modified Miyota 9015 movement as the standard production variant (all of which you can read more about in Thomas Calara’s post introducing the watch back in June). The dial of the Year of the Dragon is where the differences between this limited edition and the standard model start to show themselves. The Year of the Dragon opts to replace the frosted black and anthracite dials of the standard release with a more exciting deep red, three-dimensional, textured, “blasted dragon scale” motif. I’ve never seen a dial quite like this before, and while the name alone would be enou...

Roger W. Smith and His Unique Series 1 Made for British Watchmakers’ Day

British Watchmakers’ Day is nearly upon us. Tomorrow, March 9, watch lovers from across the UK (and across the world – our own Zach Weiss and Blake Malin will be in attendance) will descend on Lindley Hall in Westminster to celebrate all that British watchmaking has to offer. The event is run by the Alliance of British Watch and Clockmakers, and was conceived to raise awareness and money for the Alliance, which works to support watchmaking in the UK by fostering ties between its trade members.  Roger W. Smith, the famed independent watchmaker who famously apprenticed for George Daniels, was an early Alliance member and one of the group’s most vocal supporters. He’s taking part in British Watchmakers’ Day this year alongside many of his colleagues in the Alliance, and he’s particularly excited about the diversity and the representation from a new generation of watch brands that will be present. “The vast majority of our trade members are outside of traditional horology,” Smith told me in an interview. “That’s very exciting to me, it means we’re going to have lots of innovation, lots of ideas, and new stories taking place.”  One of those new stories is a watch Smith himself will be presenting at British Watchmakers’ Day, which is loosely organized around participating brands bringing limited edition pieces to sell for one day and one day only at the fair. For Smith, this presents a challenge and an opportunity. His watches are largely made by hand...

Explained: Barrels, Mainsprings, and the Trade-off Between Power Reserve and Energy SJX Watches
Mar 8, 2024

Explained: Barrels, Mainsprings, and the Trade-off Between Power Reserve and Energy

Every mechanical watch employs at least one mainspring barrel as its energy source. When a watch is wound, the coils of the mainspring tighten, storing potential energy which is then slowly released through the gear train to the escapement. The mainspring is enclosed in a toothed barrel, essentially a drum covered by gear teeth. As a result the barrel is often considered to be the first wheel of the going train.  Although one is the norm, two or even more barrels can be employed, typically to generate more energy. Double barrel movements usually feature two mainsprings kinematically linked in one of two ways: in parallel or in series. The number of mainsprings, energy stored, and power reserve are illustrated with equations (1), (2), and (3): As described by equation (1), the energy of a single barrel E is a function of its torque, angular discharge velocity and running time (autonomy). Linking two identical barrels naturally means having twice the energy, so 2E. By convenient association, equation (2) exploits the available energy to double the torque sent to the gear train, while equation (3) takes advantage of the total energy by doubling the running time.  Parallel barrels The parallel arrangement of barrels embodies equation (2), which delivers twice the torque, increasing the energy available to run the movement (but not increasing the running time). Here two barrels unwind at the same time on a centre pinion connected to a second mobile of the going train. An embo...

Louis Erard Watches: How the Regulator King Became an Indie Darling Teddy Baldassarre

Louis Erard Watches: How the Regulator King Became an Indie Darling

Louis Erard is one of those Swiss watch brands that may have registered on your radar only recently - earning both enthusiast buzz and critical acclaim in the past few years thanks to its very high-profile partnerships with indie watchmakers whose own timepieces might otherwise be unattainable. How did Louis Erard, which actually traces its origins all the way back to the Great Depression, manage to finally find its niche in the 21st Century? Family Foundations Born in 1893 in La Chaux-de-Fonds, a historical hub of Swiss watchmaking, Louis Erard discovered his horological vocation early. In the early 1900s, he began plying his trade as a watchmaker for several of the town’s workshops, and in 1929 founded a watchmaking school where he served as instructor. At the same time, Erard started a watchmaking business with a partner named André Perret, originally as an “assembler” of complete timepieces for third parties using parts supplied by independent artisans. By 1931, the partnership was dissolved and Erard became a producer of watches under his own eponymous brand name. The company grew in the following decades, with Erard’s two sons, René and Jean-Louis, joining in 1945. Among the company’s milestones during this early period was helping to develop the now-legendary Valjoux 72 chronograph caliber. In 1956, Louis Erard, which still used third-party movements in its own watches, advanced to the next stage of horological prestige, starting production of it...
