Rolex Watches For WWII POWs And The Great Escape

World War II wreaked havoc around the globe. Many millions died, and at times, it must have felt like the end of the world as nations committed everything to defeating their enemies. Rolex also lent a hand in a small way by providing timepieces to prisoners of war (POWs). As a graduate history student, I […] Visit Rolex Watches For WWII POWs And The Great Escape to read the full article.

Purnell Escape II Double Tourbillon: Double Triple-Axis Spherical Tourbillons At That!

Complicated haute horlogerie doesn’t get much better than twin triple-axis spherical tourbillons as found in the Purnell Escape II Double Tourbillon. And while in some cases less is more, here more is definitely more. The tourbillons are mesmerizing in part thanks to their high rotation velocity; they make full revolutions in respectively 8, 16, and 30 seconds. What is behind this masterful piece of high watchmaking?

Up Close: Purnell Escape II Double Tourbillon

Given that the tourbillon was invented for the pocket watch, adapting Abraham-Louis Breguet’s invention for the wristwatch opened the floodgate for tourbillon innovations in the beginning of the 21st century – the golden age of the tourbillon, perhaps technically but surely commercially. In fact, many watchmakers have gone far beyond the traditional concept of a tourbillon since English watchmaker Anthony G. Randall invented the double-axis tourbillon in 1978. But as the years passed, tourbillons evolved into elaborate constructions seemingly just for the sake of visual complexity. And there have been so many of them. For this reason, exotic tourbillons now seem dated, with sophisticated or truly interesting technical solutions being hard to come by. Potter and Purnell But the latest development in tourbillons is one of the most intriguing of recent times: maximising the visual effect of a tourbillon regulator not just by multiplying the axes of rotation, but speeding them up with the use of a specialised escapement invented two centuries ago by Albert H. Potter, a highly regarded American watchmaker based Geneva. The full potential of the Potter escapement was recently realised when it was combined with a carrousel outer cage in the MB&F; LM Thunderdome, the world’s fastest rotating triple-axis tourbillon. But the concept was first applied, arguably in a more elaborate manner, in the Spherion tourbillon of Purnell – which was developed by the same watchmaker behin...

Conversations: American Watchmakers Jason Lu and Zach Smith of 1776 Atelier

The 250th anniversary of the founding of the United States did not escape notice from the nation’s fledgling watch industry. To mark the occasion, 1776 Atelier released the Liberty 250, a watch credibly claimed to be more than 90% US-made. The brand’s most American-made and technically ambitious watch to date, the Liberty 250 also illustrates the difficulty of building a complicated mechanical product without an established domestic supply chain. Its HP 917 movement is the product of extensive iterative development, incorporating newly manufactured components, a free-sprung balance and a markedly more elaborate finishing programme. We sat down with the brand’s co-founders, Jason Lu and Zach Smith, to unpack the 90% figure, discuss the challenges of manufacturing watches in the United States and understand what the Liberty 250 means for the future of the brand and American watchmaking more broadly. The Liberty 250 is the most American-made product yet from Atelier 1776. The interview was edited for length and clarity. Brandon Moore (BM): Why start a watch company in the United States, particularly given the limited domestic supplier network and the additional cost involved? Jason Lu (JL): Because this is where we live, and this is where we wanted to build it. The United States was founded on ingenuity, and American watchmaking has a remarkable history. The fact that much of the former infrastructure no longer exists does not mean it cannot be rebuilt in a new form. Th...

Assembled By Me: Inside Studio Underd0g's Watch Assembly Experience

In 2020, watches became a real escape for a lot of us. Instagram, Facebook groups, even Clubhouse (who remembers that?) were thriving, and for me, watches had become more than a 9-5 as I fell deeper into those communities. It's where I first came across a guy on Facebook talking about a watch he'd designed that was 'inspired by a watermelon'. Every time it appeared, the comments filled with feedback as he gauged whether people were actually interested. They were. And now, six years later, that man, Richard Benc of Studio Underd0g, has just opened the doors to his very own watch assembly workshop here in the UK called 'The D0ghouse'. Roughly 45 minutes by train from Central London, the building in Maidenhead is a fusion of creative interior design and legitimate horological assembly, and anyone can experience the process first-hand. For £700, Studio Underd0g will sit you at a watchmaker's bench and guide you through the assembly of your own watch. What they're offering isn't a tour or just a showroom (they have that on-site, too), but a set of tweezers, a loupe, and an opportunity to experience the Underd0g, hands-on. That alone makes The D0ghouse worth the journey, but having just completed the experience myself, what I didn't expect was how much it would adjust my understanding of what this six-year-old brand has actually become. The Unassuming Townhouse From the outside, The D0ghouse is simply a Victorian townhouse on Park Street, the same address that Benc's friends an...

Doxa Introduces the Long Awaited Sub 200 T.Graph II

Doxa is one of those watch brands where the lore is kind of hard to escape. Every release is the subject of intense enthusiast discussion as the watches are contextualized through a complex history. There’s real mystique to the brand, which I think largely stems from the fact that Doxa’s dive watches were always true enthusiast products, made for actual divers as tools of their trade. This sets them apart from Rolex, Omega, and many other Swiss luxury houses, not because they didn’t also make tools for real divers (they certainly did), but because they also focused their attention on more mainstream pursuits. Doxa, at least in the public imagination, 50+ years on, did not. They’re seen as a brand for purists, and still appreciated by them to a great extent, even if they sometimes do something that’s a little on trend. There’s perhaps no watch in their catalog with more lore attached to it than the Sub 200 T.Graph, a chronograph version of the Doxa’s iconic Sub 200 diver. This watch was briefly released in a very limited way all the way back in 2019, and, ever since, collectors and fans of the brand have been clamoring for a non-limited edition. This week, Doxa has given the people what they want, with the introduction of the Sub 200 T.Graph II.  The new Sub 200 T.Graph II is, at least on the surface, exactly what you’d expect a modern, permanent version of the T.Graph to be. It is sized down just slightly from the 2019 limited edition, with a 42mm case in ...

Photo Essay: Patek Philippe Rare Handcrafts 2026 Honours the Power of Nature

As Watches & Wonders drew to a close, Patek Philippe opened its annual exhibition of Rare Handcrafts at its salon on Rue du Rhône. It was a peaceful escape from the hustle of the Palexpo, and the perfect setting to view several dozen pieces from the new collection, ranging from Dome Clocks to wristwatches and pocket watches. The exhibition is open to the public until May 9th. Attendance is free, but visitors must register in advance online. Dome Clocks Among the prevailing themes of this year’s collection, the power of nature featured prominently. The Dome Clock ref. 20202N-001 “Magma” is the perfect example. The organic composition is almost shocking in its simplicity and minimal palette of just five colours of transparent enamel — and just seven more used for miniature painting. The volcanic depiction is undeniably violent in a way that creates a pleasing tension with the controlled techniques employed to create it, including silver leaf paillonné and a needle technique for creating the lifelike look of the volcanic rock, outlined with more than 23 g of gold wire. Of course, fired enamel has a lot in common with magma. In short, this choice of molten medium contributes to the authenticity of the work. The glowing lava is mirrored on the dial with 12 large baguette-cut sapphire hour markers totaling about 3 cts. Like the other Dome Clocks featured, the Magma is powered by an electrically wound 17’’’ pocket watch movement that offers a look into the firm...

Orient Star’s M34 F8 Skeleton is Space-Age Tech

Orient Star marks a milestone with the M34 F8 Skeleton Hand Winding 75th Anniversary, combining the brand’s technically adept, manually wound skeleton calibre with a novel, laser-engraved meteorite pattern in a maximalist open-worked package. The M34 F8 Skeleton also stands out for the tech inside the mechanical movement: proprietary silicon escape wheel with a novel, optimistic geometry that helps the M34 punch above its weight from a technical standpoint. Initial thoughts Last year, Orient Star launched the brand’s first manually wound moon phase – made of mother-of-pearl no less – for fans of understated, formal watches. Now celebrating its 75th anniversary, Orient Star has cast aside restraint to mark the occasion with something for a more maximalist breed of collector. The new skeleton has a blacked-out case and bracelet and an open-worked version of its top-of-the-line F8 movement. Notably, the movement plates are bridges, which are exposed front and back, are decorated with a laser-etched meteorite motif that is impressively detailed. This skeletonised anniversary limited edition also features the latest technology from its powerhouse parent company Seiko Epson, including a silicon escape wheel with an especially advantageous design. While silicon is increasingly common in the watch industry, it is used primarily for hairsprings. This puts Orient on the list of short brands with a proprietary silicon escape wheel that includes blue-chip names like Patek Phil...

Holiday Lookbook: Cabin Couture Essentials with Bremont’s Supermarine 500m Polar

The Bremont Supermarine 500m Polar feels tailor-made for a holiday escape to the woods, starring an icy dial that echoes fresh snow, paired with the sort of rugged dependability you want when you’ve traded city noise for crackling logs and cold morning air. Its crisp, high-contrast aesthetic is unfussy and calming, the visual equivalent of that first deep breath you take after settling into a quiet, wood-paneled retreat. Whether you’re strumming a guitar by the fire or stepping out for a morning hike through frost-covered pines, the Supermarine 500m Polar is exactly the kind of companion you want on your wrist. Its 43mm case crafted from corrosion-resistant 904L stainless steel shrugs off bumps from thrown-together gear and cabin chores, while the robust 500 meters of water resistance gives you the confidence to take on whatever the terrain and weather decide to throw your way. This is a tool watch in its element… comfortable, capable, and never demanding attention.   The post Holiday Lookbook: Cabin Couture Essentials with Bremont’s Supermarine 500m Polar appeared first on Worn & Wound.
