Seiko Pours a “Root Beer” Prospex LX GMT
Seiko has introduced the Prospex LX GMT SNR058, a luxury-leaning sport watch inspired by the constellation and intended exclusively for the US market. Executed in Zaratsu-polished titanium with Diashield coating, it pairs a richly textured gradient dial with a Spring Drive GMT movement more commonly associated with Grand Seiko. In doing so, the SNR058 blurs the line between Seiko and its grander cousin, inviting comparison not on branding, but on tangible quality. Initial thoughts According to Seiko, this US-exclusive special edition evokes the North America Nebula in the Cygnus constellation, named for its resemblance to the continent. It is, presumably, a coincidence that the dial also recalls a frosted glass of root beer; arguably a more recognisable symbol of the US market than any nebula. Regardless, either reading feels apt for a United States-only edition. On paper, the Prospex LX line blurs the line between the Seiko and its grander cousin. The collection holds up well next to similar watches from Grand Seiko, pairing a more assertive, utilitarian aesthetic with a more cohesive bracelet design. Branding aside, it also presents stronger value proposition thanks to its Diashield-coated titanium case and bracelet; the equivalent models from Grand Seiko come dressed in heavier stainless steel, which scratches (but can also be refinished) more easily. The Prospex LX GMT also benefits from a toolless micro-adjustment system for the bracelet, something increasingly sought...

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...

Omega Co-Axial Movement Explained: A Radical Invention
What is a Co-Axial Movement? More specifically, what is the now-famous Co-Axial Escapement that has become a standard feature on most all Omega watches? In short, it's both a radical concept by one of the modern era's most revered watchmaking geniuses and the culmination of a Swiss watch brand's longtime dedication to improving watchmaking accuracy. Here is the story of Omega's co-axial movements. [toc-section heading="Early Omega Movements"] While it is best known these days for its signature watch models, like the Speedmaster “Moonwatch” and the James Bond-worn Seamaster, Omega has also been a pioneer in movement-making since nearly the beginning. The company was founded in 1848 by 23-year-old watchmaker Louis Brandt (with family, above) in the Swiss village of La Chaux-de-Fonds. Originally called La Genérale Watch Company, and eventually renamed Louis Brandt et Fils after Brandt’s sons joined the business, it originally produced key-wound pocket watches from parts supplied by local artisans, After the growing company moved from La Chaux-de-Fonds to the more bustling town of Bienne, in the Swiss Canton of Bern, it pioneered a series of industrial watchmaking techniques and also began making its own in-house movements. The first one, called the Labrador, launched in 1885 in a now-legendary series of pocket watches. Nearly a decade later, in 1894, came the company’s chef d’oeuvre, the 19-ligne Omega Caliber, which was notable at the time for its enviable acc...

Breguet’s Magnificent Magnetic Expérimentale 1
Breguet concludes its 250th anniversary with the brand’s most forward-thinking watch, the Expérimentale 1 that boasts a magnetic, true constant force escapement. Equipped with a frictionless escape wheel and pallet lever driven by magnetic forces, the movement runs at 72,000 beats per hour, or 10 Hz – arguably making the Expérimentale 1 the ultimate Breguet chronometer. Impressively innovative with its use of silicon, magnets, and clever teeth geometry, the limited edition watch also marks the start of the Expérimentale line, a collection that will serve as a platform to debut new complications, technology, and designs. Initial thoughts While some might have been expecting an updated Sympathique, Breguet instead surprised with perhaps the most advanced wrist-borne mechanical chronometer in modern watchmaking. Taking cues from Abraham-Louis Breguet’s own “constant force” escapements, Breguet today harnessed the power of permanent magnets and unique teeth geometry to built a genuinely friction-less, constant torque escapement. In fact, the new escapement appears to be the only truly frictionless and constant force escapement on the market today. Magnets have been employed in escapements in the past, but this approach was historically unreliable. Breguet appears to have discovered the right formula for a magnetic escapement. Several functioning prototypes were on show at the launch event. Moreover, Breguet chief executive Gregory Kissling explained that the ma...

Complicated Collectors: Gerd Ahrens
In the autumn of 1948, at Galerie Fischer’s auction house in Lucerne, a young Swiss watchmaker secured Lot 155, a Breguet pocket watch, No. 4763, circa 1848, with a straight-line club-tooth lever escapement. The case, fitted later by E. Brown at George Daniels’s suggestion to employ original movements and parts held in stock, aligned with his purpose. For most collectors, such a purchase might not have represented a pure Breguet. But for Gerd Ahrens, it was something altogether different: the first sentence in what would become a four-century narrative of mechanical ingenuity. Gerd Ahrens in his shop office on Schwanenplatz 7 around 1955. Image – Gerd Ahrens Foundation: a life built on wheels and springs Gerd Ahrens was born on September 18, 1920, in Hamburg, Germany, at a time when mechanical watches represented the pinnacle of portable precision. His father, Otto Ahrens, born in 1877, had already established himself as a highly respected watchmaker. Otto’s path, however, would be marked by the upheavals of the twentieth century. Before World War I, he had operated a successful shop in Paris and had built connections throughout the watchmaking centres of Inner Switzerland. The evidence of his skill was tangible: Otto personally built ten pocket watches, demonstrating not just commercial acumen but genuine mastery of the craft. Then the war came. Otto was forced to close his Paris shop in 1914, and the conflict left him penniless. A trained craftsman of the highest...

Highlights: Complicated Patek Philippe at Christie’s Hong Kong
Christie’s Hong Kong returns this autumn with an extraordinary offering of rare and important Patek Philippe watches, headlined by a ref. 1518 in yellow gold. The auction is defined by two major private collections, most notably Part 2 of The Chronicle Collection - the successor to this spring’s successful first chapter. From neo-vintage rarities to heavyweight modern complications, the sale presents one of the of the most interesting Patek Philippe selections of the season. Lot 2225 – Patek Philippe Ref. 3979HJ Minute Repeater The story of Patek Philippe’s mastery of the modern minute repeater begins in 1989 with the launch of the ref. 3979 and the calibre R 27 PS. Launched to commemorate the brand’s 150th anniversary, the ref. 3979 was the brand’s first automatic minute repeater, and its first wristwatch to feature a silent centripetal governor, which was still novel at the time. According to the serial number, the present lot was the 47th ref. 3979 to be made, out of approximately 100 units produced over a nine year run. Further distinguishing the current lot is its classical enamel dial, which was a relatively uncommon configuration for this reference. The compact 33 mm yellow gold case is a love letter to classical dress watches. The case itself was made by Ateliers Rèunis, the brand’s own case maker, and was manufactured in the building that now houses the Patek Philippe museum. Today, more than 35 years after its launch, the cal. R 27 PS is still am...

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.

Hands On: Breguet Four-Minute Tourbillon No. 1890
In the coming weekend, one of the most important watches of this auction season will go under the hammer at Sotheby’s Breguet’s 250th anniversary thematic sale November 9 – Breguet no. 1890, a pocket watch with tourbillon and natural escapement made by the firm by Breguet while Abraham-Louis Breguet himself still helmed the company. The gilt dial with a regulator-style layout might seem familiar – the recent Classique 7225 reproduces this dial design. In fact, Breguet no. 1890 isn’t the only watch in this style; it belongs to a series of pocket watches all equipped with a four-minute tourbillon and échappement naturel from the early 19th century that were among the finest watches of the time. Breguet built just eight four-minute tourbillons with natural escapement, all of which thankfully survive, and only three with gold dials. King George III ordered the most famous example – almost identical to this watch – during the Napoleonic wars. For context, that would be like Churchhill (who owned a Breguet himself) ordering an A. Lange & Söhne watch during the Second World War. As such, it was signed Recordon, Breguet’s London agent, to disguise its French origins. Whirling About Regulator Almost 225 years ago, the French Ministry of the Interior granted A.-L. Breguet a patent for his most famous creation, the tourbillon – a clever exercise in lateral thinking.

Ahead of Its 50th Anniversary Year, Raymond Weil Introduces the Toccata Heritage Capsule Collection
Watches & Wonders can be a blur of new releases in and of itself. So, when a brand asks if you want to preview some upcoming introductions for the year ahead, it can start to make your head spin. However, at my Raymond Weil appointment this past spring, I relinquished. The brand had a small display of archival pieces in a vitrine at their booth, and its Chief Marketing Officer Jeremie Bernheim assured me the reveal would be worth viewing alongside the mini museum of vintage designs. What he shared with me was a new capsule within Raymond Weil’s Toccata collection drawing from the retro models and aptly named Toccata Heritage. Today, this collection comes to you in nine styles, each more beautiful than the next, and with the option of either quartz or mechanical, manually wound movements for the first time. If you have followed Raymond Weil through any point of its nearly 50-year history, you know the brand loves to play with shape and case architecture. The existing Toccata collection explores this with a combination of rectangular and round models. For the new Toccata Heritage capsule, the maison has refined this design language even further. Here, you have a shape the brand simply calls oval, but in my humble opinion, this description does not do the case justice. The case design of the new Toccata Heritage models is decidedly not the harsh, egg-shaped oval profile you might associate with other watch brands. Instead, it takes the structure of the current rectangular m...

Zenith Defies Gravity (Again) to Mark 160 Years
Zenith’s 160th anniversary celebration continues with the Defy Zero G, a sapphire-cased watch equipped with the brand’s latest generation, gimbal-like “Gravity Control” escapement module. Available in either clear or deep blue sapphire – both with a lapis lazuli dial – the 46 mm anniversary model is a literal showcase for the innovative cal. 8812 S, which features a gimballed escapement platform that keeps the balance wheel in a horizontal position at all times. Originally developed in 2008 and refined in 2018, the Zero G mechanism is a modern homage to Zenith’s legacy in competitive chronometry and marine navigation. Initial thoughts Today, the Zenith brand is synonymous with the El Primero chronograph movement, launched back in 1969. But outside of that, the manufacture has always been a major force in Swiss precision watchmaking. For decades the brand regularly took home the top prizes at chronometry trials from Neuchâtel and Teddington. Zenith already paid tribute to its past success in competitive chronometry with the G.F.J. cal. 135, which also features a lapis lazuli dial, but it’s reassuring to see the brand made time to bring out one of its more recent developments for its anniversary year. While the days of chronometry trials are long past, Zenith has still managed to make a name for itself when it comes to the accuracy of wrist-worn timepieces - at least theoretically. Back in 2008 the brand unveiled a curious mechanism, with the escapement fu...

Grand Seiko Introduces the SLGB005 “Violet Dawn”
Earlier this year at Watches & Wonders, Grand Seiko revealed the SLBG003, which turned out to be one of the most impressive watches of the whole show. Housing the new 9RB2 Spring Drive caliber, the UFA (Ultra-Fine Accuracy) movement is certified to an almost incomprehensible +/- 20 seconds per year, or roughly 3 seconds per month. That makes it, according to Grand Seiko, the most accurate movement powered by a mainspring. It’s a truly impressive horological achievement. Of course, as soon as a brand like Grand Seiko introduces an entirely new platform like the UFA, enthusiasts are on pins and needles waiting to see what comes next. It’s not that we can’t appreciate what we have in front of us, but particularly with Grand Seiko, we know that variants are coming in the form of new dial options and case materials. If you had asked me in the Spring when we’d see the first derivation on the UFA line, I probably wouldn’t have expected to see a new watch so soon, but last week Grand Seiko dropped the Evolution 9 Spring Drive UFA SLGB005, nicknamed the “Violet Dawn” for its deep purple dial. It’s always interesting to see what new watches in a new sub-collection come to pass, not just for what it says about where the line is going, but perhaps where it’s not. The SLGB005, like its predecessor, is what we’d probably call a small-medium size by today’s standards, measuring a conservative 37mm. Unlike the titanium SLBG003, however, this watch is clad in a st...

Audemars Piguet’s Royal Oak Chronograph RD#5, a Thin Watch with Tall Ambitions
Audemars Piguet (AP) reinvents the chronograph with the Royal Oak “Jumbo” Extra-Thin Selfwinding Flying Tourbillon Chronograph RD#5. Inside the titanium and palladium BMG case – standing just 8.1 mm high – is the cal. 8100, a new take on the chronograph mechanism that employs spring-loaded racks to gather and store energy. The RD#5 is the fifth and final instalment in the “RD” series of watches that underline the impressive technical know-how of AP, particularly its Le Locle manufacture that evolved from Renaud & Papi (APRP). Conceived with the goal of creating a chronograph that is extra slim and easy on the fingers, the RD#5 boasts exceptionally light and comfortable pusher feel, an instantaneously-jumping minutes counter, and an exceptionally slim profile (thanks in part to peripheral winding), all while remaining amenable to industrial-haute horlogerie manufacturing. It’s one of the most technically interesting debuts of 2025, and we explain AP’s new take on the chronograph in detail below.

Grand Seiko’s UFA in Steel for the First Time
Grand Seiko unveils a second model in its Ultra Fine Accuracy (UFA) collection, the Evolution 9 Spring Drive UFA SLGB005. Featuring a violet-black dial inspired by Shinshu winter sunrises and powered by the latest generation spring drive technology, it represents everything Grand Seiko does best. Limited to 1,300 pieces, the 37 mm SLGB005 is made from the brand’s proprietary Ever-Brilliant steel, an especially hard-wearing alloy that’s making its debut in the Evolution 9 Spring Drive line-up. Initial thoughts The Spring Drive UFA SLGB003 “Ice Forest” was arguably one of the most important releases of this year, finally delivering a long-awaited mid-sized Grand Seiko Spring Drive, complete with an adjustable clasp and tightened accuracy rating. The SLGB005 feels like a worthy counterpart in another metal, quantifiably excellent inside and out. The SLGB005 retains the nearly perfect proportions of its titanium sibling at 37 mm in diameter and 11.4 mm thick, in a slightly heavier Ever-Brilliant steel case. Though Grand Seiko has used this material in the past, it’s the first time it’s been used for a Spring Drive watch in Evolution 9 guise, and also the first to be made at Shiojiri. This is a new colour of an existing dial pattern. Grand Seiko’s dial work is always excellent, especially the hands and dial furniture, which are finished to unusually high standards. The Spring Drive movement remains the same and excellent. While not mechanical, I’d argue that Spr...

Grand Seiko Goes Gold
Grand Seiko has unveils three gold Spring Drive models with the new 9RA2 movement, the Japan-only Heritage Collection SLGA030, SLGA027 and SLGA028, in rose, white, and yellow gold respectively. The new collection benefits from a slimmer case, a longer power reserve, and some new dials to go with the satisfying heft of a full 18k gold bracelet that weighs in at almost 200 g. SLGA030 in rose gold. Initial Thoughts While mostly unknown outside Japan, a trio of gold Spring Drive models in 44GS-style cases on full gold bracelets were a staple of the domestic Grand Seiko catalog for nearly a decade, powered by the cal. 9R15 that was once the brand’s finest automatic Spring Drive movement. While identical to the cal. 9R65, save for a gold medallion on the rotor, Seiko set aside the best performing quartz timing packages for these special movements. The earlier generation of all-gold models, from left to right: SBGA364, SBGA361, and SBGA362. Grand Seiko has decided that now is the time to refresh the line with the upgraded cal. 9RA2, while preserving the heavyweight gravitas and luxurious bracelet of its predecessor. I have anticipated these watches since the second generation of Spring Drive movements launched in 2020; it took five years, but the result meets my expectations, though I would have liked a gold winding weight to match the case material. Selling watches on full precious metal bracelets in this segment is a mark of a strong brand. Gold prices and luxury margins bein...

The 15 Best British Watch Brands (2026)
While Switzerland is regarded today as the world leader of watchmaking, Great Britain can lay claim to a wealth of horological milestones throughout its history as well. From Thomas Mudge’s development of the lever escapement in 1755 to John Harrison’s invention of the marine chronometer in 1759 to the innovations of clockmaker Thomas Tompion and his protegé George Graham in the areas of science and astronomy, England was an undisputed leader in timekeeping throughout the 18th and 19th centuries. The 20th century brought the decline of the British Empire and, with it, British watchmaking, as nations like Switzerland, Germany, and (for a while) the United States stepped in with modern mass-production techniques while the Brits held fast to traditional, artisanal methods. The United Kingdom essentially ceased being a major producer of timepieces by the end of World War II, but as the 21st Century dawned, a handful of entrepreneurial Britons have made great strides in bringing high-end watchmaking back to their native land, establishing new brands - and in some cases, resurrecting old ones - to make watches that appeal to today’s discerning enthusiasts in the U.K. and across the world. Whether the focus is military-style tool watches, avant-garde complications at approachable prices, or ultra-high-end pieces for well-heeled collectors, each brand boasts an identity that is proudly British and at the same time distinct from its peers.

Insight: Hairspring Materials and Evolution Part II
Part I of our story on the evolution of hairspring materials covered temperature compensation along with the development of the first specialised balance spring alloy, Elinvar. The story brought us to the 1920s, when scientist and horologist Charles-Edouard Guillaume (1861-1938) finished his work on nickel-iron alloys and watchmakers begun embracing Elinvar springs paired with mono-metallic balances. In this second part we turn to newer hairspring alloys, like the now-ubiquitous Nivarox. Then we look at today’s landscape and the future, touching on research done by the Swatch Group with alternative, niobium-based alloys and also the specialised but obscure Seiko SPRON 610 hairspring. Lastly we discuss silicon springs, which are growing more prevalent across a range of timepieces. Elinvar’s weaknesses Elinvar was by far the greatest breakthrough in self-compensating alloy hairsprings at the time. Guillaume considered Elinvar good enough and not needing further improvement - unsurprisingly since he was its inventor - but other watchmakers and engineers continued to experiment with iron-nickel compounds because Elinvar’s inherent properties made it a good, but imperfect, material. Even though the alloy behaved predictably with temperature changes, its physical properties were not ideal to begin with. Elinvar was a soft metal, which posed its own suite of problems for spring applications. The importance of softness in terms of hairspring performance is not related ...

Five Lightweight Knives Perfect for Summer EDC
Just over a month ago, several of our contributors, myself included, penned an article about our favorite summer watches. While we each had a personal preference and strong reasoning behind our choices, it got me thinking about my summer EDC, and how it changes as temps begin to rise. Throughout winter and spring, I tend to carry larger pocket knives, but I find myself reaching for lighter options as the temperature and humidity increases. While they’re just as capable as anything else, these lighter blades carry more comfortably in shorts, and I even forget I’m carrying them sometimes. With this in mind, I thought it might be a good idea to list out some of my favorite summer EDC knives and why I reach for them. Before we dive in, let’s look over the parameters I used to select these knives. I think one of the most ambiguous qualities that I’ll talk about is “lightweight”. While there isn’t a set standard and everyone is likely to have their own opinions, I’m using 2.5 ounces (70ish grams for my metric friends) as my max weight. As I’d come to find out while verifying the weight of my included knives, many of the staple EDC options fall under this weight! Using this weight also prevents me from sneaking in some of those heavier knives that I enjoy so much. Secondly, the knife has to be safe to carry in your pocket. While a single utility blade is very lightweight, having an exposed, sharp edge in your pocket just seems like a terrible idea. Along these l...

Typsim Makes Watches for the True Watch Nerd
Typsim, the Seattle based brand run by Matt Zinski, has been on my radar since the spring of 2023, when I met Matt at the Windup Watch Fair in San Francisco. Typsim was not exhibiting at this show, but that’s frankly sometimes my favorite way to meet a brand owner. The young, hungry brands that show up just to be there, and maybe don’t have a fully baked idea quite yet, are sometimes the most interesting ones to track. To be fair, I think Typsim was pretty well baked by the time I found out about them – my lack of knowledge before 2023 can be chalked up to my own blind spots and the simple fact that nobody can keep up with everything. Matt’s background is in architecture, and the stated goal of his brand is to create watches with a clarity of design and thoughtfulness that you’d associate with a well conceived building. The first watch he showed me that day in San Francisco was the diver, called simply the 200M, which honestly felt like a fairly generic (though very well made) vintage inspired dive watch, except for one thing: it makes use of an exclusive lume compound that promises to patina with time. That little detail has been stuck in my head ever since, and I think it unlocks something about the appeal of the brand. Matt is both a genuine watch nerd and a true tinkerer, someone willing to experiment and shoot for details that, realistically, only matter to a very small handful of super nerds, like me, and like Matt, and, I’m sure, like his customers. ...
