First Look - The New Watch Ho & Co. x Selten Jui, a Celebration of Community and Craft

Watches are built to tell time, but also to impress, and to connect. The Jui is a collaboration between Watch Ho & Co., a Hong Kong-based watch community and club founded by Jackie Ho, and indie brand Selten, and it belongs firmly in the latter category. Created to mark Watch Ho & Co.’s second anniversary, […]

Industry News - The Impact of the 39% U.S. Tariff on the Swiss Watch Industry, And The Reactions of A Major CEO, the Swiss Fed and an Analyst

On August 1st – also known as Switzerland’s National Day – the Trump Administration announced a 39% tariff on Swiss imports, coinciding with Secretary of State Marco Rubio publicly praising Switzerland… A political and economic shockwave has gripped the country for nearly two weeks. Rightfully so, Switzerland is heavily export-oriented, and the U.S. is one […]

Interview: Kari Voutilianen on Urban Jürgensen and Artisanal Watchmaking

Urban Jürgensen made its comeback earlier this year with an impressive line-up that includes the flagship UJ-1 Tourbillon. Much of the credit for the brand’s watches and watchmaking goes to Kari Voutilainen. Mr Voutilainen has imbued Urban Jürgensen’s watches with the high standards of quality synonymous with his own brand, resulting in watches that are equally exquisitely craft and steeply priced, but arguably worth it. Though best known for his eponymous brand, Mr Voutilainen is also co-chief executive of Urban Jürgensen (and also a minority shareholder). His fellow steward of the Danish marque that is now headquartered in Bienne, Switzerland, is Alex Rosenfield. While Mr Voutilainen is in charge of watchmaking, Mr Rosenfield leads marketing and branding. From left: Kari Voutilainen, Andrew Rosenfield, and Alex Rosenfield. Image – Urban Jürgensen Given the opportunity to speak at length with Mr Voutilainen, I could not refuse. We discussed the true nature of artisanal work, ranging from movement decoration to guilloche, the details of Urban Jürgensen’s movements, and more. You can find his insightful answers below. But interestingly, my conversation with Mr Voutilainen reminded me of the first time I met him, which was at Baselworld 2006 when he launched the Masterpiece Chronograph (with a special hairspring from what turned out to be a questionable supplier). Even two decades ago, well before he was famous, Mr Voutilainen was passionate about the same thing...

Five Mistakes I Made While Collecting Omega Speedmasters (And How To Avoid Them)

I bought my first Omega Speedmaster Professional in 1999. This is also when my Speedy collecting officially began. During those 25 years of buying (and selling) Speedmaster watches, I made my fair share of mistakes. This was mainly because, back then, there wasn’t as much information available as there is today. But I also made […] Visit Five Mistakes I Made While Collecting Omega Speedmasters (And How To Avoid Them) to read the full article.

The Op Art-Inspired Anoma A1 Optical is Not an Illusion

Anoma made its debut last summer and has just released its third model, the A1 Optical. Without departing too far from what made the previous models attractive and affordable, the latest variant features a CNC guilloché dial with a shimmering optical effect. For the design of the dial, Anoma founder Matteo Violet-Vianello was inspired by the works of Bridget Riley and Ferruccio Gard, instrumental figures in the optical art movement. There are two dial options for the Optical; copper and silver. The copper option is the livelier of the two and will inevitably be called a salmon dial. Alternatively, the silver-treated option gives the watch a distinctly black-and-white feel. Interestingly, the first 150 pieces in each dial finish will be delivered with a related artwork commissioned from optical artist Adam Fuhrer. After the first 300 pieces have been delivered, regular production (sans artwork) will commence. Initial thoughts It’s rare to find watchmaking at this price point that is distinctive enough to sell without a name on the dial, but Anoma is betting the A1’s pebble-like triangular case is a recognisable enough calling card to dispense with the branding. It was the right call, because the Optical is all about its dial and the shimmering optical illusion created by programmatic guilloché. In some ways the dial motif is similar in concept to the Bulgari Octo Finissimo Tadao Ando, but the triangular pattern and three-dimensional texture will result in a more engag...

Seiko Samurai Review: Smaller And Better Than Ever

Last year, we saw a trio of new Seiko Samurai watches that aimed to broaden the collection’s appeal within the Prospex family. It’s fairly well understood that the Samurai has been seen as the odd man out among the “Seiko with a nickname” family, but why exactly is that? Well, it doesn’t have that vintage heritage, having only debuted in 2004. Also, the second generation has been around since 2017, and since then, tastes have certainly changed. The 44mm-wide case is a little too big for today’s tastes, where conventional wisdom puts anything above 42mm safely in the “huge” category (the case has been pretty thick, as well) . And while models like the Turtle, SKX007, or Willard (or even Tuna and Arnie) have rounded cases, the Samurai’s case has a very sharp and almost aggressively angular design that, again, is not for everyone. Wisely, Seiko’s third-generation Samurai addresses that persistent case-size issue while giving the dial a refresh too. Fortunately, the angular case is a bit more refined, yet no less geometrical. Sorry, that’s just part of the Samurai’s identity. Seiko Samurai Case and Bracelet First off, yes - the new Seiko Samurai has taken design cues from the Shogun. If that makes it not a “true Samurai,” then so be it, but the end result is one good-looking watch. The case improves over that of the second generation in just about every meaningful way (the older case is still available alongside this new iteration). First off, it ...

Fratello EDC: Daan Shares His Everyday Carry Essentials From The North Face, Montblanc, Bellroy, Serengeti, And More

I am not entirely sure why, but back in 2022, I didn’t participate in the Fratello EDC (Everyday Carry) series. That’s great because it allows me to go all out this time. Some of the things I’ll mention today have been with me for quite a few years now, while others are more recent acquisitions.

Put on your breathing apparatus as the fascinating stories of these two watches are told by Colin Alexander Smith here.

A. Lange & Söhne Datograph Perpetual Tourbillon Reviewed by Tim Mosso: A Machine with Heart and Soul

The A. Lange & Söhne Datograph Perpetual Tourbillon lives up to its name. It has a date, a chronograph, a perpetual calendar, and a tourbillon. But it has more: this watch has character. Assigning human traits to a cold machine is a – romantic – fool’s errand, but it’s also irresistible in the presence of a masterpiece. A. Lange & Söhne’s warmest watch is more than a machine with a heartbeat. It has soul.

Bulgari “Beyond Time” Exhibition and a Singapore-Exclusive Octo Worldtimer

Bulgari has just opened Beyond Time in Singapore, which takes place in Paragon Mall from July 18 to August 10, 2025 and is open to the public daily. An exhibition dedicated to the brand’s watches and jewelled timepieces, Beyond Time also marks the launch of the Octo Roma Worldtimer SG60, a limited edition only for Singapore. The exhibition includes the record setting Octo Finissimo complications – some of the thinnest wristwatches ever made – as well as a watchmaking “masterclass” led by a watchmaker from Bulgari’s Neuchâtel manufacture. Singapore National Day The event coincides with Singapore’s 60th year of independence on August 9. For the occasion, Bulgari has created the Octo Roma Worldtimer SG60, a limited edition accented in white and red, the national colours of Singapore, with a case in black DLC-coated steel. Other goodies specific to Singapore’s National Day weekend include postcards by Singaporean artists, and personalised poetry verses. The Octo Roma Worldtimer SG60 is delivered on a pair of straps in red and black Located on the ground floor of the mall, the B-shaped exhibition space is inspired by the work of German architect Mies van der Rohe and his close collaborator, designer Lilly Reich. The exhibits are organised thematically, with the Serpenti and Octo collections each having a space of their own, but the complicated watches are the centrepiece. The complicated watch display showcases the brand’s accomplishments in pushing the bound...

SJX Podcast: Are Watches Too Expensive? And Discussing Bundling.

This week’s podcast starts with two hot topics – retail prices of watches and “bundling”, or having to buy one watch (or several) in order to get something desirable. The episode also includes several watches we covered recently, including the Vacheron Constantin “Tribute to the Celestial” and the Louis Vuitton Tambour Taiko Spin Time.

Catching Up on New Releases from Ming, Wren, Squale, and Doxa

Happy Saturday! Dive watch summer continues – we’ve noticed some fun new divers, all limited editions, come across the transom lately. New water ready releases from Doxa, Wren, and Doxa are profiled below. We’re also spotlight the latest from Ming – while not a diver, it has a stealthiness to it that feels appropriate for the season. Let us know in the comments what you think of these new releases, and what we might have missed. Wren Diver 38 Wren is back with their second watch, the all new Diver 38. The brand, founded by Wrist Enthusiast’s Craig Karger, launched last year with the Diver One, and the new piece is a scaled down, and perhaps more refined take on the original concept. The new version of the watch is smaller, coming in at, you guessed it, 38mm, and is just 10.7mm tall (the original was 41mm in diameter and over 13mm thick). The dial has a sandwich style design, in either a gradient seafoam green or aqua colorway. According to Karger, the goal here was to move Wren into a new category that “balances practicality, comfort, and refined execution.”  The Wren Diver 38 is available in date and no-date versions for $1,595. It runs on a ETA  2892 automatic caliber, and has 200 meters of water resistance. It’s mounted to a flat-link, stainless steel bracelet, and the ceramic bezel insert is fully lumed. Another nice touch: the rotor is skeletonized in the shape of a wren. More information on the Wren Diver 38 can be found on the Wren website here. Mi...

Insight: Hairspring Materials and Evolution Part I

The invention of the hairspring was among the greatest breakthroughs in horology, since its inception suddenly made mechanical timepieces portable, transforming clocks into watches. This not only marked the start of precision timekeeping, but also set mankind upon the long road to perfecting the accuracy of mechanical watches, arguably the most sophisticated pieces of kit on Earth at the time, when such precision was paramount for fields as varied as navigation, warfare, and astronomy. The hairspring turned 350 years old in 2025 and we’re marking the occasion with a series of stories on the topic, including the story of the spiral hairspring and also the importance and evolution of the overcoil. Now we turn to temperature compensation and metallurgy in a two-part story covering the evolution of the hairspring materials up until metal alloys. More exotic materials and inventions will follow in Part II. Elasticity and thermal expandability  One of the fundamental factors in hairspring function is ambient temperature, simply because metal alloys expand or contract uni-directionally with a change in temperature. As a result, watchmakers used calorimetry, the science of temperature effects, and material science, specifically metal alloys, to their gain in advancing hairspring technology. The equation below shows the relation between the initial length of a metal strip L0, measured at a given temperature and the final length LT after a certain change in temperature.  The equ...

SJX Podcast: Urban Jürgensen’s Revival, Breguet’s Birthday, and Spring Auctions

SJX and Brandon Moore kick off episode seven of the SJX Podcast with the relaunch of Urban Jürgensen (which includes a tribute to Derek Pratt’s Oval pocket watch), discussing why this time might be different. Also on the docket is a recap of the spring auction season, which included strong prices for hot names in independent watchmaking, though other “indies” waned, surprising showings from hitherto esoteric clocks and pocket watches, and some value buys with out-of-vogue timepieces. Lastly, we recap Breguet’s 250th anniversary launches so far, which have met with a mixed reception, but demonstrate signs of life for a historic brand.

Introducing: The Ressence Limited Art Watch Type 8 × Daniel Engelberg

We all know Benoît Mintiens, founder of Ressence, doesn’t shy away from using multiple colors on his user-friendly spherical watches. The brand’s minimalist Type 8, however, has always had a more modest, single-color design - until now. In collaboration with German painter and sculptor Daniel Engelberg, Ressence presents us with the Type 8 DE1 in […] Visit Introducing: The Ressence Limited Art Watch Type 8 × Daniel Engelberg to read the full article.

The Lanco Alarm: Appreciating Langendorf’s Innovative and Overlooked Single-Crowned Mechanical Alarm

It’s no secret that the visuals of a watch are often why collectors pull the trigger on adding yet another piece to their collection. It could be a specific color, the inclusion of a certain desirable bezel insert, the symmetry of a double register chronograph, or many other aesthetic reasons. This isn’t to say that the movement and build quality are not also a part of this decision-making process, but one of the chief reasons many of us love to collect is for the joy we feel putting one on wrist, potentially matching it with an outfit, and gawking at it throughout our busy days. What I wish to do here is move away from this mindset and instead appreciate how mechanical ingenuity can produce the same amount of excitement and allure. This Lanco Alarm watch may seem relatively lackluster at first glance. A simplistic silver case and dial with very few flashy or notable design choices, it could be easily mistaken for dozens of watches and brands who sold timepieces in the 1960s and 70s. Its most interesting characteristic is perhaps what’s most unremarkable on any other vintage dress piece: the use of a single crown.  By the 1960s, brands like Vulcain, Jaeger-LeCoultre, Poljot, Girard-Perregaux, Citizen, Bulova, and Helbros had released their own alarm watches, many of which utilized movements made by outside movement manufactures like A. Schild and Venus. The common denominator between these models and movements was the two crown layout: one typically adjusted and wou...

Ressence and Ahmed Seddiqi Celebrate 75 Years With A Sand-Filled TYPE 9 S75

Louis Erard and Konstantin Chaykin Unveil a Third Round of their “Time Eater” Collaboration

Louis Erard and Konstantin Chaykin, the only Russian member of the AHCI, have teamed up once again for a new batch of their hit “Time Eater” collaboration. It’s been about two years since their first collaboration, which was an immediate hit for both parties and sold out quickly. A follow up limited edition came a few months later, this one much darker in tone, both in terms of the dial and case, and also the mood of the piece- that bloodshot eye really leaves an impression. For their third release, Chaykin and Louis Erard have returned to their original idea, offering a pair of watches that fans of the original who might have missed out will likely be quite interested in taking a look at when they go on sale in a few days.  The fact that this collaboration exists at all is one of the things we like most about Louis Erard as a brand. They’ve really found a niche in developing limited edition projects with interesting collaborators both in and outside of the watch industry. A watchmaker like Konstantin Chaykin, who has risen to prominence in recent years with his “Wristmons” series of watches, makes watches that are likely out of reach for most collectors. But through Louis Erard, Chaykin, along with watchmakers like Stefan Kudoke and Vianney Halter, brings his design ethos down to earth, making it approachable to enthusiasts who admire his work but would never be able to spend tens of thousands on a single piece. Together with Louis Erard, Chaykin has essentia...
