Albishorn Introduces their Latest “Imaginary Vintage” Type 10 Worn & Wound

Albishorn Introduces their Latest “Imaginary Vintage” Type 10

Albishorn is a brand based on one of the most tantalizing concepts that we’ve come across: vintage watches that never existed. I’ve thought about this conceit quite a bit since the brand was launched a few years ago. In some ways, it’s not so different on the surface from any other “vintage inspired” watch. The vast majority of them, after all, never existed. The Black Bay, for instance, takes inspiration from a great many vintage Tudor and Rolex watches, but it’s not a one to one recreation of anything – it never actually existed. But Albishorn is different. They place their watches in an imagined reality. Each one is its own “sliding doors” moment brought to life in watch form – a thought experiment about how things might be if they had turned out just a little differently.  The Type 10 is pitched as an imaginary ancestry to the Type 20, a very real watch that just about everyone reading this will be at least somewhat familiar with. Imagining a predecessor to the Type 20 also means imagining the infrastructure to create it, the timeline on which it would have been made, and even design details that might have been improved or altered in the later (and real) watch.  Today, Albishorn releases a new variant of the Type 10, which they’re calling the Type 10 Officer. Like previous Type 10s, this is a monopusher chronograph designed in the language of military issued watches. This one has a white dial, which the brand explains makes more sense for an Of...

Hands On: Chopard L.U.C. Grand Strike SJX Watches
Chopard L.U.C Grand Strike Dec 11, 2025

Hands On: Chopard L.U.C. Grand Strike

The 30th anniversary of the Chopard L.U.C. manufacture was one anniversary among many this year, but it will likely be remembered thanks to the Grand Strike, the most complicated watch in Chopard’s history and its first grande sonnerie. Building on the successful Full Strike minute repeater architecture and making full use of the brand’s patented sapphire gongs, the Grand Strike is a chronometer-certified two-train clock watch with a push-button minute repeater. In this context, the presence of the tourbillon is almost a footnote. Initial thoughts I can count on one hand the number of brands that have created their own grande sonnerie wristwatch. It’s one of the few things in watchmaking that’s proven challenging enough to still be rare, even in the days of computer-aided design (CAD) and advanced manufacturing technology like wire erosion. For this reason, the grande sonnerie has a towering cultural presence among watchmakers and collectors, looming above all other complications. For Chopard, the Grand Strike represents the culmination of 30 years of the L.U.C. manufacture, the brand’s haute horlogerie division. The first impression of the Grand Strike is one of extraordinary depth. There’s not much of a dial, save for the minutes scale etched on the inside of the sapphire crystal, and the small concentric sub-dials for the dual power reserve displays. This depth shrinks the watch visually, and it feels dense and compact despite its rather large 43 mm size and...

What is a Quartz Watch? Everything You Need to Know Teddy Baldassarre
Dec 10, 2025

What is a Quartz Watch? Everything You Need to Know

The advent of the quartz watch was the most disastrous event ever to befall the traditional luxury watch business, an existential threat that nearly toppled the watch industry as we know it. The invention of the quartz watch was among the most significant advances in the history of timekeeping and brought affordable wristwatches to the masses in a way that had never been seen before. These are the two main schools of thoughts on what the quartz watch has meant to the history of watchmaking, and both are essentially correct. As you contemplate whether to purchase a quartz watch, ponder the main differences between quartz and mechanical movements, and try to wrap your head around the various types of timekeeping technologies, let’s explore how quartz watches originated, how they evolved, and what their place is in today’s ever-changing watch world.  [toc-section heading="Quartz Movements Explained"] Unlike a mechanical movement, which stores its energy in a wound mainspring inside a barrel and releases it through a complex series of gears to move the hands, a quartz movement derives its power from a small electrical charge provided by a battery, which then passes through an integrated circuit that applies the charge to a tiny quartz crystal cut into the shape of a tuning fork. Thanks to something known as the reverse-piezoelectric effect, that tiny charge applied to the quartz tuning fork crystal causes it to vibrate at an incredibly high rate that dwarfs the output of ...

Laco Celebrates their 100th Anniversary with a Tribute to their Past

As I’m currently in the process of planning a 15-year anniversary, I can tell you one thing, Reader: it’s not easy finding a way to pack so much into only one measly day. I mean, does a single night out sharing a Caesar salad and a couple cocktails convey all the love, memories, and various milestones? Probably not. But it’s the thought that counts, right?  But, then again, maybe I’m just doing it all wrong. Take, for example, the German watchmaker, Laco, who is celebrating a much more impressive anniversary this year: their 100th. Instead of doing a two-for-one special at a chain restaurant (which is always my back-up plan), they released a watch to celebrate the occasion: the Edition 100, which is, in a way, a culmination of an ongoing mission from the brand, which has released five limited-edition releases in the past, each celebrating a key chapter in Laco’s history. For the Edition 100 specifically, the brand used the 1950’s as the springboard for the design, taking inspiration from an archival model. While the cleaner lines, slim bezel, and two-tone colorway might all read as Art Deco-adjacent, Laco’s contemporary design language, such as adjusting proportions for a more modern appearance, has filtered through to make a watch worthy of bridging the gap between the watchmaker’s past and present. The 38mm stainless-steel case is coated in a gold-tone IP, which, in turn, softens the black center of the dial and complements the champagne outer ring simul...

Down to the Wire: De Bethune’s In-House Hairsprings SJX Watches

Down to the Wire: De Bethune’s In-House Hairsprings

De Bethune plans to bring hairspring production in house, aiming to become one of the very few firms able to process alloy wire into a finished balance hairspring. This requires De Bethune’s new hairspring workshop to master wire drawing, rolling, cutting, heat treatment, and assembly. The rationale? “Externally produced hairsprings meet standards based on averages that do not enable fine adjustment of the dimensions to suit a particular balance wheel or its specific positioning in a calibre,” according to De Bethune. De Bethune’s “flat end curve” mated to a hairspring sourced from a supplier. Initial thoughts As De Bethune explains it, making its own hairsprings will allow the brand to tailor its hairspring to a specific balance or movement. Since its founding in 2002, De Bethune has presented itself as being on the cutting edge of chronometry, debuting a new balance design every year from 2004 to 2010. The brand was also quick to embrace silicon, and even briefly attempted a kilohertz magnetic oscillator system, Résonique. A new year, a new balance. Sometimes two new balances. Given De Bethune’s focus on chronometry, making its own hairsprings seems like a natural next step. However, there is a reason so few brands make their own hairsprings: the process is a difficult and demanding one that benefits greatly from economies of scale. For example, H. Moser & Cie. makes less than 4,000 watches per year, however, its sister company Precision Engineering claims...

The Urwerk UR-230 Goes Dark SJX Watches
Ulysse Nardin Dec 10, 2025

The Urwerk UR-230 Goes Dark

Urwerk’s latest satellite-display creation, the UR-230 Black Star, builds on more than two decades of the brand redefining the wandering hours complication. A concept first teased in the Harry Winston Opus 5 and later perfected in the UR-210, the retrograde-satellite display has become synonymous with Urwerk’s identity, and the Black Star demonstrates how far the idea has come. With a lightweight fibreglass-reinforced ceramic case, the Black Star is a 35-piece limited edition that looks to be the final instalment of the UR-230 series. Initial thoughts Urwerk didn’t invent the wandering hours display, but the brand deserves credit for dragging the complication into modernity in the late 1990s. While the brand has dabbled in watches with conventional hands, it’s still the satellite time display that carries the essence of Urwerk’s DNA. The UR-230 traces its roots back to the 2012 launch of the UR-210, which introduced the retrograde frame that travels with the satellite cube for hours. The concept for a retrograde hand paired with wandering hours dates back even further, to the 2005 launch of the Harry Winston Opus 5, which was also designed by Urwerk. While the concept has subsequently been elaborated with the UR-150 Scorpion, the UR-230 still looks strikingly advanced even after all these years. The latest black-and-yellow livery seems to be the flavour of the day, closely matching the brand’s recent collaboration with Ulysse Nardin. The signature detail of the...

In-Depth: Understanding Isochronism and Oscillators SJX Watches

In-Depth: Understanding Isochronism and Oscillators

The beginning of 2025 marked the 350th anniversary of the hairspring, the invention that made portable precision timekeeping possible. To commemorate the occasion, we published a series of deep dives covering the disputes around its invention, the evolution of spring materials over the years and the finer rules of forming Breguet overcoils. This final instalment examines isochronism. Some initial definitions and considerations A proper and universal definition of isochronism is: the property of an oscillatory system to maintain the same period of vibration despite variation in environmental factors. This implies that a vibrational system’s behaviour is inherent and external factors should not influence its frequency.  A few basic terms help frame the discussion. The period, measured in seconds, is the time taken for the oscillator to travel from one extreme position, through equilibrium, and back again. Frequency, measured in Hertz, is the inverse of the period; a system with a constant period can serve as a stable timebase. The amplitude is the distance swept by the oscillator from the equilibrium point to its extreme position. In practical terms, when saying that a sprung balance has an amplitude of 330°, it means the balance wheel rotates a full 330° in one direction from its equilibrium point before swinging back.  Figure I. Anatomy of a sinusoidal wave. In watchmaking parlance, isochronism means that an oscillator keeps the same period, regardless of its amplit...

Best Solar-Powered Dive Watches For Every Budget

While solar-powered quartz technology has been around for decades, it’s still a relatively new innovation in the centuries-old watch world. I wouldn’t say the solar-powered revolution has fully arrived (especially as contemporary enthusiasts continue to find appeal in the craftsmanship of mechanical calibers in an increasingly digital world), but the technology has undoubtedly become more reliable and refined in recent years. The convenience and ease of being able to charge up your watch in both natural and artificial light sources, as well as the security of the long-lasting battery life, actually lend themselves well to more high-stakes and tactical situations. Riffing on that theme, I’ve scoured the watch industry for the best solar dive watches on the market. Down below, you’ll find what I believe to be the most compelling solar divers out there for your reading pleasure, offered at a wide range of price points so everyone can get in on the fun.  [toc-section heading="Citizen Eco-Drive Promaster Dive Titanium"] Case: 44mm, Material: Super Titanium, Water Resistance: 200 meters, Caliber: E168 Solar, Price: $575 It was Citizen who truly revolutionized the genre of solar-powered watches in the '90s.
