Introducing – The Arnold & Son UltraThin Tourbillon Onyx Edition

Arnold & Son’s UTTE – Ultra Thin Tourbillon Escapement – debuted at Baselworld 2013, powered by the ultra-thin 2.97mm hand-wound calibre A&S;8200. Recognised as the world’s thinnest tourbillon wristwatch, the title was stolen from Arnold & Son just one year later with Bulgari’s 1.95mm Octo Finissimo Tourbillon. Still remarkably thin, Arnold & Son’s Ultrathin Tourbillon […]

Hands-On: The New Porsche Design Chronograph 1 All Titanium Numbered Edition

The Chronograph 1 is Porsche Design’s champion by some margin. In fact, you could probably make a case for it as a candidate for the top 100 most influential watches of all time. Why? Well, for starters, launched in 1972, it was the first all-black watch, which started a lasting trend. Second, the design language, […] Visit Hands-On: The New Porsche Design Chronograph 1 All Titanium Numbered Edition to read the full article.

Sinn Introduces the 544 and 544 RS Ahead of their First Watches & Wonders

Sinn makes their Watches & Wonders debut this year. It’s kind of a big deal, or should be, in our community, and honestly it’s not being talked about enough. Watches & Wonders is the premier trade show in our industry, but unlike Basel World (where Sinn was well represented before that show’s demise) it’s not a full representation of the watch industry. It’s selective, and focused primarily on luxury brands that are part of large luxury groups, and primarily Swiss luxury brands at that. This year’s show expands in a meaningful way with the addition not just of Sinn, but of Credor (a Japanese brand) and Audemars Piguet (technically independent, and inarguably one of the most important brands in our industry commercially). But Sinn feels like ours, they are an enthusiast staple through and through.  Sinn has announced a small series of novelties ahead of Watches & Wonders, and we’ll be bringing you coverage of all of them after we get some hands-on time with the watches next week. But today we’ll focus just for a moment on what is likely the most straightforward, tool oriented release of the bunch, and maybe of the entire Watches & Wonders event this year, the 544 and 544 RS. I’m not a huge fan of the “Go Anywhere, Do Anything” tag that often gets lumped in with watches like this, but that, I think, is truly what we are looking at here. The 544 is a completely new offering from the brand, but collectors will likely notice that the case seems derived fr...

The Hamilton Fontainebleau “Day ‘N Date” 6004: The Potential Catalyst for an Innovative Case Design Renaissance

I feel that the contemporary watch market has a noticeable lack of fun, exciting, and unique watch case designs. Brands have put a major emphasis on dials made from rare materials or composed of intricate designs recently, but very few companies have put time into producing cases that offer a special experience for the wearer. Round and tank-styled timepieces are, and will forever be, the norm within the watch industry. However, this gap in the modern market gives collectors a chance to look back into vintage catalogs to familiarize themselves with fads and stylistic ventures of previous horological eras. With this in mind, I’d like to take a trip back to 1968 and examine the creation of the Hamilton Fontainebleau series, specifically the 6004 “Day ‘N Date” reference, to exhibit just how innovative case design can truly be. It’s typically an overlooked piece of the design formula, but when a watch features a case profile unlike any other, it certainly stands out among the pack. A Brief History of Fontainebleau and the 6004 In 1966, the patents for Hamilton designer Ulrich Nydegger’s new case were published. A couple of years later, the first few Fontainebleau models hit the market and garnered a decent amount of popularity. It wasn’t until 1969’s Fontainebleau Chrono-Matic chronograph, however, that the line would see a substantial amount of press and recognition for its innovative design. The collectibility of the Chrono-Matic model continues to increase o...

Announcing – The Naissance d’une Montre 4 “Le Carrousel” Project and the Birth of Bonniksen

Few initiatives in modern watchmaking genuinely place craft above product. The Time Æon Foundation is one that looks to safeguard and transmit traditional handmade techniques at the highest level. Its Naissance d’une Montre series has become the best expression of its mission, not just watches, but workshops of knowledge, where historical methods are relearned, applied, and […]

Introducing – Ressence Unveils the Type 11 Powered by its First Proprietary Movement

Since its founding in 2010 in Antwerp by Belgian industrial designer Benoît Mintiens, indie brand Ressence has positioned itself as a design-led watch studio that literally rethinks how time is displayed on the wrist. Animated by Ressence’s Orbital Convex System (ROCS), time circles around the dial like planets orbiting the Sun, using highly graphic and […]

Ressence Debuts the Type 11, with the All New In-House RW-01 Movement

For as long as we’ve talked about Ressence, part of the discussion has always been about how clever they are for producing such an ingenious and unique system for time telling, all built on top of a standard, off-the-shelf ETA movement. Their patented ROCS module, which displays the time via a series of rotating discs rather than traditional hands, is a complicated piece of engineering that has always lived alongside a caliber that is rather ordinary. For me, and many others, this was always part of the charm of a Ressence watch, and underscored the idea that watchmaking is a broad discipline and that with some creativity even a simple ETA movement can be turned into something extraordinary.  That changes a little today with the introduction of the Ressence Type 11, featuring the all new RW-01 movement, the first in-house designed Ressence movement. Designed specifically to power the ROCS, the RW-01 is an integrated, automatic caliber that appears to be an improvement in just about every way over previous movements found in Ressence watches.  First and perhaps most notably, this movement has a 60 hour power reserve, which can be monitored on the dial via ceramic micro balls. For years, Ressence watches have featured power reserves that topped out at slightly less than the ETA movements they were based on due to the demands of running the ROCS module. But the RW-01 was designed from the ground up to work with ROCS, eliminating many of the compromises made with previous ...

Ressence Introduces First Proprietary Movement

Independent watchmaker Ressence unveils the Type 11, powered by a proprietary movement for the first time. The trailblazer of oil-filled mechanical modules, Ressence has so far relied on third-party base movements to power its eccentric creations. The Belgium-based watchmaker has finally taken the next step and developed its own calibre, dubbed the Ressence-Werk RW-01.  Initial thoughts  Ressence watches are instantly recognisable for their inventive and minimalist way of telling the time, using the patented Ressence Orbital Convex System (ROCS) to put a new spin on the classic time display. Using a clever arrangement of planetary gears powered by a base movement, Ressence has achieved an original functional design that remains unique to this day.  In terms of design, Ressence has an unmistakable, contemporary look, not unlike that of Apple. As a result, partnerships like those with industrial designer Marc Newson feel natural. The concept behind Ressence’s signature time display is the use of clear silicone-based oil which fills the hermetically sealed ROCS module to the crystal. The fluid medium cancels out total internal reflection, leading to the illusion that the turning disks sit right under the crystal itself. In this respect, Ressence dials can at times look like an OLED screen in a smartwatch. The Type 11 continues the signature streamlined minimalism of past Ressence models, but adopts a less complicated display. There are hours, minutes and seconds, arrange...

Most of you know the deal with Ressence watches by now. The highly original creations by Belgian designer Benoît Mintiens tell the time through an intuitive layout. The watches don’t use conventional hands; instead, they feature several eccentric satellites. Until now, the brand’s so-called Ressence Orbital Convex System (ROCS) was always powered by a highly […] Visit Ressence Enters A Completely Different Ballgame With The New Type 11 And Its First Fully Integrated Movement to read the full article.

Bonniksen Reborn with Handmade Le Carrousel SJX Watches

Bonniksen Reborn with Handmade Le Carrousel

Bonniksen makes its debut with the aptly named Le Carrousel, a 30-second carrousel wristwatch that will launch under the secondary banner of Naissance d’une Montre 4, which means it will be fully handmade. Le Carrousel’s completion date has not been announced, but good things take time, especially when made without the assistance of automated machinery. Left to right: Bonniksen co-founder and CEO Jason Chevrolat, Greubel Forsey CEO Michel Nydeggar, Bonniksen co-founder Maximin Chapuis, and David Bernard from the Time Æon Foundation. Initial thoughts It’s shaping up to be a big year for independent watchmaking, with a number of new and old names making their debuts. Bonniksen is among the latter, and looks to be a good-faith effort to do justice to the legacy of the inventor of the carrousel. While the rebirth of an old name is a familiar (if not tiresome) formula, one can’t help but appreciate the care with which the name of Bonniken makes its return. For one thing, the movement, which still exists only in sketches and models, is a true carrousel, built to co-founder Maximin Chapuis’ design after 5,500 hours of technical research. In other words, it’s not just an old name attached to an off-the-shelf calibre. The fact that it will debut as a Montre 4 in the Naissance d’une Montre project is another reason to take the effort seriously. If that weren’t enough, the brand has apparently been given the blessing of Bonniksen’s living descendants, which helps t...

Hands-on – The New, Blue-Toned Greubel Forsey Balancier 3 in Titanium

Greubel Forsey has always been synonymous with highly complex, intensely finished movements presented as three-dimensional mechanical sculptures. In recent years, the brand has explored a slightly more “restrained” yet modern approach with models like the Balancier S and, more recently, the Balancier 3 introduced in 2023. The time-only Balancier 3 retained the brand’s signature depth […]
