Space Time: Seiko’s Star-Powered Astron GPS SJX Watches

Space Time: Seiko’s Star-Powered Astron GPS

In the run-up to the holidays, Seiko facelifts its high-spec, multi-function quartz watch with the Astron GPS Solar refs. SSJ039 and SSH187 - limited editions of its satellite-linked models. While not available in stores until January, the new references make their public debut almost exactly 56 years to the day when the original Astron, the world’s first quartz wristwatch, was launched on December 25, 1969. Initial thoughts Despite pioneering efforts to develop quartz watches in Switzerland, and the commercialisation of category-defining products like the Swatch, the alpine nation has tended to lag a step behind its rivals from the land of the rising sun when it comes to quartz technology. As quartz watches matured and the underlying technology became commoditised, much of the Swiss watch industry redoubled its focus on mechanical watches, seemingly content to cede quartz leadership to brands like Seiko and Citizen. For their part, the dominant Japanese brands have continued to develop quartz watches with conscientious enthusiasm, bringing solar charging, radio frequency and satellite-based connectivity, and ultra-precise oscillators to maturity. In that context, the Seiko Astron is the embodiment of more than half a century of quartz leadership, and combines several of the brand’s strengths in two distinct limited edition models. Though the four-figure prices may come as a shock to buyers more familiar with offerings from brands like Apple, Garmin, and Casio, the A...

Omega Speedmaster MK40 Review: A Colorful Cult Classic Teddy Baldassarre

Omega Speedmaster MK40 Review: A Colorful Cult Classic

When you think of the Omega Speedmaster, the first thing that comes to mind is likely the brand’s golden child, the Speedmaster Moonwatch Professional. It’s a modern grail with its NASA connection, and its intertwined history with the Moon landing and space exploration is its calling card. But today, we’re looking at a different Speedmaster that has been eschewed from Omega’s current lineup. One that’s a little more playful, a little more unconventional, than the brand’s well-established Moonwatch Professional formula: the Speedmaster Mk40. Down below, I’ll be breaking down the history, context, and all the aesthetic oddities of the watch, all of which work together to create one of the most compelling non-Moonwatch Speedmasters of all time, in my humble opinion.  [toc-section heading="Some Speedmaster Context"]  Image: S.Song From first glance, the Speedmaster Mk40 that made its debut in the ‘90s defies all the utilitarian, tool-watch-oriented austerity that is the key DNA of the Moonwatch Professional, from its functionality to its experimentation with color, shapes, and typography. But the Mk40 is part of a short-lived and often forgotten legacy of Omega’s experimentation with the Speedmaster formula, before things were so rigidly codified as they are today. It is also important to note that the moniker “Mk40” itself is a completely enthusiast-driven nickname, which Omega itself has never officially used (the brand denotes the different models wi...

Longines Sector Dial Review: Trendsetting Vintage Style Under $3,000 Teddy Baldassarre

Longines Sector Dial Review: Trendsetting Vintage Style Under $3,000

The Longines Heritage Classic Sector Dial has, in its relatively short time on the market, set itself apart from the rest of the Swiss brand's vintage-inspired Heritage series with its combination of retro charm, understated dimensions, and minimalist aesthetics, all at a very approachable price point, Here is a closer look at the watch, with a brief foray into other recent timepieces that just might have been inspired by its success.  [toc-section heading="A Bit of Longines History"] Longines was founded in 1832 in the Swiss Jura town of Saint-Imier by Auguste Agassiz and two partners. Agassiz (above, left) became the sole proprietor in 1846 after both partners, attorneys by trade, retired from the watch business, and shortly thereafter, he brought his nephew, an enterprising economist named Ernest Françillon (above, right), into the company. It was Françillon, in 1867, who moved all of the firm’s various watchmaking disciplines - which were scattered throughout dozens of independent workshops called établisseurs - under one roof, to a factory that was situated in a scenic area called “Les Longines” or “The Long Meadows,” thus giving the company its now-familiar name.  In 1889, Francillon registered the famous Longines logo with a winged hourglass - today the world’s oldest unchanged, active logo according to the World Intellectual Property Organization (WIPO). Among Longines’ many milestones under Françillon’s management were the company’s ...

Best Luxury Watches For Women Teddy Baldassarre

Best Luxury Watches For Women

There comes a time in every watch-loving girl’s life in which she’s ready to take the plunge into the pool of luxury. To ascend from the endless eBay lowballing and bidding on eBay watches under 100 bucks, and start stashing away cash to save up for the big purchase. For the “future heirloom” watch that haunts her dreams. While that day has yet to come for me, I have amassed an ever-growing wishlist of pieces that might one day be my first, big watch splurge – once I stop dipping into the proverbial piggy bank, that is. Below, I have gathered what I believe to be the best luxury watches for women available today.  Before we get into the fun part, I want to state first that I like to think of luxury as a state of mind. There are going to be some pretty “pie in the sky” watches on this roundup, which, no matter how frivolous I dare be, I will probably never be able to go into a store and purchase. But what we can distill from these extravagant, top-tier luxury watches is certain design codes, case shapes, and aesthetic choices that catch our eye, and bring us closer to finding a more reasonably priced option. If you, like me, cannot drop thousands of dollars on a watch without bringing shame and ruin upon yourself and family, think of this as digital window shopping. I have thrown some pieces on the list that are a little more reasonable as well, which to me, capture the essence of luxury and have made me feel luxurious while trying them on, in pursuit of maki...

Orion Watches Founder Nick Harris on Growing His Brand Through Adversity Worn & Wound

Orion Watches Founder Nick Harris on Growing His Brand Through Adversity

I’m going to go out on a limb and guess that most of you reading this right now won’t know the name Nick Harris. Don’t worry, I’m not calling anyone out; if you weren’t a dedicated Seiko modder on the right forums at the right times, it’s not a name you’re likely to have come across. Nick, despite being an accomplished watchmaker and avid enthusiast, just isn’t as well-known as the brand he created, Orion Watches. It’s not a huge surprise. As enthusiasts, we tend to have a better memory for brands and watches than we do for people (how many of us have pulled some variation of the classic, “I can’t remember his name, but he had that great vintage Sub”), and that tendency easily extends to brands, even small ones. It’s easy to forget that many of the brands we talk about on Worn & Wound, and so many of the watchmakers that get us excited, aren’t really “brands” in the typical sense. Many of our favorite brands aren’t machines operating with marketing departments, state-of-the-art production facilities, and overflowing C-Suites. What we broadly call “brands’ are usually the result of the passionate work of one, or maybe two, dedicated creators, their brand names and logos serving more as a personal maker’s mark than as an identifier for a sprawling and impersonal corporate structure. The consequence here is that it can be easy to conflate these small one-man shops with their more established brethren. That can make it particularly diffi...

Patek Philippe’s Grand Exhibition Returns to Europe in Milan

Patek Philippe has just revealed details about the Watch Art Grand Exhibition Milan 2026, which is set to take place in October 2026. The event marks the seventh edition of the brand’s large-scale public exhibition series, and its return to Europe following the most recent instalments in Tokyo, Singapore, and New York. The biggest yet With a display area covering 2,540 square metres, the exhibition will be the largest Watch Art event organised by Patek Philippe to date. As with previous events in the series, the exhibit will feature immersive replicas of the brand’s Salon on Geneva’s Rue du Rhône, the manufacture at Plan-les-Ouates, and the Patek Philippe Museum, all constructed under the dome of the Palazzo delle Scintille, now known as CityOval. For a taste of what’s in store, the Patek Philipe website still hosts an immersive experience of the 2022 edition in Tokyo. The exhibition will showcase the brand’s entire current collection, alongside a dedicated Rare Handcrafts selection comprising dome clocks, pocket watches, and wristwatches, with around 500 pieces in total on display. Artisans will also be on hand to demonstrate techniques like miniature enamel painting, cloisonné enamel, hand engraving, wood marquetry, guilloché, and gem-setting. As is customary for Watch Art exhibitions, the Milan event will see the launch of several limited-edition watches across different segments of the collection. The 2023 Tokyo exhibition, for instance, included a Rare Ha...

Albishorn’s Type 10 Officer Takes Flight SJX Watches
Dec 15, 2025

Albishorn’s Type 10 Officer Takes Flight

The Albishorn Type 10 Officer is the latest expression of the brand’s “imaginary vintage” philosophy, reworking the familiar codes of the mid-century military chronograph through the lens of a hypothetical Type 20 predecessor. Conceived by founder Dr Sébastien Chaulmontet, the cream-dialled Officer pairs its distinctive, parchment-like textured dial with a proprietary monopusher movement derived from a re-engineered Valjoux 7750 architecture, combining COSC-certified performance with thoughtful ergonomic and aesthetic refinements at a price that undercuts many conventional aviation-inspired chronographs. Initial thoughts Military aviation-inspired watches are a cornerstone of the luxury watch market, but most pay homage to specific historical references like the famed Type 20 of the 1950s. In contrast, the Albishorn Type 10 proposes to ‘recreate’ a hypothetical Type 20 predecessor. The cream-dialled Officer takes this idea further, suggesting a “missing link” is the aesthetic development of the military chronograph, with a lighter-coloured dial for open-air usage away from the front lines. When the Type 10 debuted with black and green dials, I was a bit skeptical of the texture, which reminded me of asphalt. The Officer’s dial features a similar texture, but the off-white colour transforms the look. To my eye, the new dial looks like vintage German etching paper, which is an appealing texture that suits the theme of the watch. Inside, the Officer is as com...

Watches, Stories, & Gear: Spielberg’s Mysterious New Film, PlayStation Watches, and More

“Watches, Stories, and Gear” is a roundup of our favorite content, watch or otherwise, from around the internet. Here, we support other creators, explore interesting content that inspires us, and put a spotlight on causes we believe in. Oh, and any gear we happen to be digging on this week. We love gear. Spielberg’s Mysterious Sci-Fi Film   View this post on Instagram   A post shared by Amblin Entertainment (@amblin) Steven Spielberg has a new, still untitled, original UFO movie coming out next year, and we aren’t talking about it nearly enough. A new sci-fi film from the director of ET, Close Encounters, AI, Minority Report, etc should be a very big deal, and it still might be once people start wrestling with the idea of Spielberg returning to this genre. Very little is known about the movie – the plot has been kept completely under wraps. But it stars Emily Blunt, filmed in New Jersey and the Hudson Valley, was written by David Koepp (a frequent Spielberg collaborator), and this week, the first bit of marketing started to hit. In a handful of cities, large billboards with the June 12 release date, an evocative image, and the words “all will be disclosed” began to appear. We love a mysterious campaign, and the idea that a new, and apparently quite major, Spielberg movie is 6 months away and we know nothing about it is tantalizing.  The Year’s Best in GPS Watches The watch world is full of little niches, and rabbit holes within rabbit holes.

My Father’s Longines HydroConquest GMT, Two Years On (Owner’s Perspective)

The Longines HydroConquest GMT is one of Longines’ most modern references, but has it stood up to two years’ worth of my father’s ownership standards? Let’s ask him! Purchasing Expectations: A utilitarian watch, fit for my dad’s lifestyle Clever micro-adjustment system A Flyer-style GMT, helpful for international travel Ownership Reality: Some design elements we disagree with Durability of the rubber strap Can you see the date? Overall Rating: 8.5/10 Value for Money: 9/10 Wearability: 9/10 Design: 8/10 Build Quality: 8/10 When it comes to dive watches, very few can genuinely be called underrated. It’s a thoroughly complete subgenre of horology, filled with some of the most iconic collections in watchmaking history. Submariner, Fifty Fathoms, Seamaster, Aquaracer, Black Bay… these are just a few names that define the dive watch enthusiast’s vocabulary. But more often than not, the price-to-performance ratio is heavily skewed. These collections carry not only cultural weight but a sense of luxury as well, and their prices rarely reflect their intended purpose. Tangentially, I told a friend earlier this year that I believed Submariners are the most mistreated watches in history: built to withstand extreme pressures, yet typically left to gather dust in a safe. Diving Into The New Longines Hydroconquest GMT 43mm One dive watch that avoids this fate is the Longines HydroConquest. Luxurious yet fairly priced, high-performance without pretension, it has consis...

Photo Report: Central Europe’s Watch Fair – Micro Praha 2025

Editor’s Note: In addition to being a writer and member of the international watch media community, Bhanu Chopra is also the co-founder of Micro Praha, a regional watch fair in Prague, which just celebrated its third year. We asked Bhanu to share his thoughts on the evolution of the event, as well as some photos from this year’s festivities. Regional watch fairs have been around for several years, but their focus remained mostly mainstream brands and few independent brands. I remember visiting Vienna Time and Munich Time in the mid-2000s, and seeing Lange & Sohne and Habring booths in the same hall. Three years ago, Ondrej Vislocky and I, two watch enthusiasts and friends, took the initiative to create a micro brand watch fair for the Central European region. Prague happens to be in the very heart of Central Europe with easy access to Germany, Austria, Slovakia, Poland, Italy, and even the Nordic countries. It also happens to be the city where we live. We are big fans of micro brands, so we wanted to bring our enthusiasm to Micro Praha. The U.K. has a very active micro indie scene with fairs throughout the year. There are watch fairs in Germany, France, Italy, and Poland, but the participation remains very regional. Micro Praha brings together brands from around the globe. This year 82 brands participated, representing 24 countries, including Germany, France, Italy, Poland, the U.S., Canada, Puerto Rico, Finland, Singapore, Taiwan, Sweden, the U.K., and Czech Republic....

Sơn Mài The use of lacquer in Asia stretches back thousands of years to ancient China and Japan, but Vietnam also developed its own unique branch of the art called sơn mài. Initially used as a protective material for everyday items like furniture, religious artifacts, and even architecture, it gradually transitioned from a primarily functional practice to an artistic one. During the Lý and Trần Dynasties, between the 11th and 14th centuries, the use of sơn...
