Tokyo Retailer Shellman Celebrates Christiaan Huygens

In order to mark the spiral hairspring’s 350th anniversary and celebrate its inventor Christiaan Huygens (1629 – 1695), Japanese watch retailer Shellman presents a two-week exhibition event in Tokyo, The Origins of Time = Astronomy. Opening November 19 and slated to run through December 2, the Shellman exhibit is a collaboration with the Musée International d’Horlogerie (MIH) in La Chaux-de-Fonds, and showcases the larger extent of Huygens’ work, from horology to optical observation devices. Themed around the Dutch scientist credited with building the first pendulum clock and with inventing the hairspring, the exhibit also explores larger fields of horology, with a focus on astronomy and modern independent watchmaking. Original drawings showing early attempts at making a sprung balance. Beyond his practical applications in horology, Huygens left marks on many other scientific fields, from geometry to physics and astronomy. He notably discovered Saturn’s largest moon Titan and cemented the wave theory of light propagation. One could say that he was interested in the celestial bodies as much as he was in understanding motion and measuring time here on Earth. In his honour, the exhibit leans on the astronomical theme as well.  The exhibition is accompanied by a selection of special watches available for sale. Visitors will have the chance to acquire the world’s smallest wristwatch planetarium, the Planetarium Christiaan Huygens Limited Edition, created by the Du...

Viridian Starfall: Orient Star’s M34 F8 Date SJX Watches

Viridian Starfall: Orient Star’s M34 F8 Date

Among Japan’s best-kept secrets, Orient Star occupies an intriguing middle ground between tradition and technology. Its latest creation, the Orient Star M34 F8 Date Green, captures that duality perfectly by combining an old-school movement with state-of-the-art dial and escapement components drawn from the vast capabilities of its parent company, Seiko Epson. The result is a watch that feels distinctly Japanese in both spirit and execution. The M34’s new green dial is embossed with a hand-engraved stamp and coated with an optical multi-layer film that creates shifting hues without a trace of pigment - an effect more often associated with much costlier watches. Beneath its shimmering surface lies Orient Star’s enduring in-house F8 movement, which continues a lineage that dates back to 1971.   Initial thoughts The dial of the M34 immediately distinguishes it within its segment. Its engraved texture, embossed from a hand-engraved die, gives the surface a natural radiance, while the iridescent green tone - created through a PVD-applied optical multi-layer film - shifts fluidly under changing light. It’s a distinctly upmarket look that signals the depth of the Epson manufacturing ecosystem behind it. The case reflects that same industrial prowess, made entirely in-house within Seiko Epson’s facilities, using 316L stainless steel finished with Sallaz (more commonly known as ‘Zaratsu’) polishing to achieve distortion-free mirrored bevels. The 40 mm size and ...

Bulgari Octo Finissimo Review: The King Of Ultra Thin Watches

The Bulgari Octo Finissimo collection has been a presence in the larger luxury-watch universe for just slightly over a decade now, but its impact has been tremendous - blazing trails of ultra-thinness in watchmaking that few brands have attempted and fewer have even attempted to rival. Today, the Octo Finissimo, in its simplest and most complex iterations, is regarded by enthusiasts as the creative cornerstone of the Bulgari brand, which up until very recently has been known more for high-jewelry watches than ambitious, record-setting mechanical complications. Here’s how the Octo Finissimo became an icon in 10 short years - starting from the very beginning.  [toc-section heading="Bulgari History (1884-1934)"] Sotirios Voulgaris, the only survivor of 11 children from a family of silversmiths in the Greek town of Paramythia, was born in 1857 and learned the family craft from his father, making jewelry as well as sword sheaths and belt buckles. After Ottoman invaders set fire to the town in 1873, the family moved to the Isle of Corfu, where Voulgaris met the man who’d become his mentor, Macedonian goldsmith Demetrios Kremos. The two artisans decided to start a business in Italy, settling first in Naples, and eventually in Rome, where they opened their first shop in 1884. After just a few months, however, the partnership ended and Voulgaris - who had now changed his name to the more Italianate “Sotirio Bulgari” - opened up his own shop, which found success sel...

Review: the Jacques Bianchi JB300 Profonde X Deepsea.edc

Being surprised by a dive watch is a rare occurrence at this point in the watch industry, except for a few brands trying to break the mold. The formula is relatively simple. Take a large case, add a snappy bezel, give it a legible design language, and what you end up with tends to be a staple model in your collection. What that leads to, though, is a sea of look-alike options with slightly different specs and price points, leading to enthusiast banter over slight obscurities. However, for a watch to tweak the formula with considered, bold design choices and still win me over is a rare thing. That is why, with over 140 brands and thousands of watches on display, I found myself returning to the Jacques Bianchi booth all three days of the Windup Watch Fair in New York City to handle the JB300 Profonde X Deepsea.edc collaboration dive watch. Unfortunately, if you were not among the over 11,000 attendees at this year’s Windup Watch Fair in NYC and, furthermore, did not manage to squeeze into the Jacques Bianchi booth, your chances of seeing this watch in person are now slim to none. Within hours of officially launching the JB300 Profonde X Deepsea.EDC, all 150 individually numbered units have officially been sold and will be delivered to their excited owners in January of 2026. Given that reaction, it’s hard to imagine this being the last we hear of these two. The fever behind the collaboration came as no surprise to me, in part due to the specifications, but also the stori...

The Wild Watches of German Polosin SJX Watches
Nov 14, 2025

The Wild Watches of German Polosin

The Kopf watch is the brainchild of German Polosin, a self-taught independent watchmaker who left Moscow for Bristol, England, where he runs Horological Underground. Conceived in 2016 and still in (limited) production today, the Kopf watch embodies the belief that a watch should be a form of mechanical sculpture. Its design feels more cybernetic than classical, combining an anthropomorphic ‘face’ with a hinged, jaw-like crown guard, hammered metal surfaces, and tritium-lit eyes. While the Kopf’s aesthetic recalls science-fiction icons like The Iron Giant or Futurama’s Bender, its construction reflects a deeply traditional craft ethos. In terms of style, German Polosin is far removed from the biker or heavy metal aesthetics one might expect from the creator of the Kopf watch. Initial thoughts It’s been more than six years since I first saw the Kopf while visiting German Polosin, the Russian [now English] independent watchmaker, who was still working in Moscow at the time. I was impressed that from the outset, the concept behind the Kopf watch was to express the art of metalworking. In this respect, he shares similarities with another independent watchmaker, the Finn Stepan Sarpaneva, who drew inspiration from biker subculture for his own creations. Mr. Polosin conceives watches as mechanical sculptures, with their shape and finish reflecting their functionality: “I would love to see it finished like… a Beretta or a Desert Eagle.” Kopf watch – the aesthetic...

Review: the Debut Releases from Kiwame Tokyo

One of the most unexpected but delightful trends to emerge in watches over the last few years is the rise of the “Japanese Calatrava” style watch. Even if you haven’t heard this term thrown around, you probably know exactly the type of watch I’m talking about, as there have been several that have emerged relatively recently. The small dress watches made by Kurono Tokyo are an obvious example, and perhaps the genesis of it all. Brands like Kikuchi Nakagawa and Noaya Hida are also part of this conversation at the more luxurious end of the spectrum, and of course there are a variety of affordable watches that sit nicely in this category or are tangential to it, like Kuoe and Orient (which admittedly has been doing this for many, many years).  I like this trend because it feels like a small segment of the watch world is pushing back on the dominant force in watches over the last decade: the vintage inspired sports watch. I’m no hater – I own a few vintage inspired sports watches and can appreciate the good ones, but they are so ubiquitous it’s tough to see them as anything but generic. The simple Calatrava style watches coming out of Japan are of course similarly generic, but are a welcome flip side to the sports watch coin, and I like the idea that someone entering the hobby now might find themselves down a rabbit hole of small dress watches as opposed to Submariner-style divers. I’d be very curious what that collector has in their watch box five or ten years...

WU25 Panel: A Conversation with Bremont CEO Davide Cerrato

Windup Watch Fair 2025 NYC might be over, but we’re still experiencing the high. One of the most popular aspects of the fair is the live panels, where industry leaders and insiders can share insights and dialogue directly with collectors and enthusiasts. There was no better way to kick off the weekend than with Bremont CEO Davide Cerrato, who graciously sat down with Worn & Wound’s Sam Amis to discuss Cerrato’s unique perspective on the industry and vision for Bremont. There is also an audience Q&A; at the end. Enjoy the full video of the interview below, or read along with the following transcript. The following conversation has been lightly edited for brevity and clarity. Sam Amis: Thanks for being here, Davide. This is going to be fun. Davide Cerrato: Thank you for inviting me. Sam Amis: Let’s start with the classic first question: what’s on your wrist today? Davide Cerrato: Today I’m wearing a very special watch that’s dear to me-a new version of the Terra Nova Jumping Hour. We launched the first version at Watches and Wonders in bronze, limited to 100 pieces. It sold out in two and a half weeks. Now we’re releasing a 904L steel version. It perfectly embodies the bold design direction Bremont is taking. Sam Amis: Love it. If you haven’t seen this watch, it’s on display upstairs. I was admiring the vertical brushing on the dial-it’s beautiful. I’m wearing a Tudor FXD, which I got when my second son was born, so it means a lot to me. I know you...

Why Watches Use IIII Roman Numerals Instead Of IV Teddy Baldassarre
Nov 10, 2025

Why Watches Use IIII Roman Numerals Instead Of IV

Watches with Roman numerals on the dial are among the most stylish and classically elegant of timepieces, despite the fact that most of them have what we might today refer to as an egregious typo. Then again, it’s not really a typo if it’s intentional, right? And the use of a "IIII" in place of the standard Roman numeral "IV" is clearly a conscious decision, as it's been commonplace for centuries. In this article, we offer some possibilities as to why. As anyone familiar with the Roman alphabet knows - and nowadays that probably includes anyone who pays attention to Super Bowl advertising - the Arabic numerals 1, 2, and 3 are rendered, respectively, as I, II, and III, but the format changes with the numeral 4, which is rendered as “IV,” and 5, which is simply “V.” Without getting too bogged down in an ancient alphabetization lesson, the first three numerals after zero (and after 5) are additive, while the one before the next major character, representing 5, is subtractive: “IV” stands for 4 because it’s five (V) minus one (I). And yet, take a glance at just about any watch dial, or clock dial, for that matter, that uses Roman numerals to denote its hours and most often you will find not a “IV” but a “IIII” - the so-called “clockmaker’s 4,” which differs from the Roman numeral we’re familiar with today.  Making watches, as any aficionado knows, is one of the most meticulous, time-intensive, and detail-oriented pursuits in the world...

Les Must de Cartier: The Misunderstood Entry-Level Cartier

The Cartier of today is undeniably a symbol of luxury and has strategically manufactured that imagery. From its quintessential deep red boxes with gold filigree border to its looping cursive script, even before you get to the object itself, whether it be jewelry or a watch, the brand has carefully crafted the entire experience of its product to position it as such. But today, we’re taking a look at an anomaly in the maison’s past, for which Cartier descended from its luxurious heights to extend its hand to the mass market. Les Must de Cartier is representative of a pivotal time in the history of watchmaking, and its contrasting accessibility played a crucial role in the maison’s longevity and its ability to weather shifting market trends. Down below, I’ll be walking you through how Must de Cartier came to be, some significant design codes, how the line has reemerged after its discontinuation, and share some musings and philosophical ponderings about this strange chapter in Cartier’s history.    Les Must de Cartier Context From its relatively humble beginnings as a local, artisanal jewelry workshop in 1847, by the turn of the 20th century, Cartier had already established itself as a global luxury powerhouse, operating in London, New York, and Paris by 1909. Each independent branch of Cartier at this time was operated by a trio of Louis-François Cartier’s grandsons, and while they often collaborated, each location developed its own unique flair and catered to ...
