Marathon Celebrates America’s 250th with a Limited Edition Pilot’s Navigator Worn & Wound

Marathon Celebrates America’s 250th with a Limited Edition Pilot’s Navigator

As many are likely well aware, 2026 marks the 250th anniversary of the signing of the Declaration of Independence, and as we approach the 4th of July, there are going to be a lot of reminders of America’s big birthday. The watch industry, as we know, loves an anniversary, and Marathon has gotten in on the act with the new edition of their Navigator pilot’s watch with a handful of patriotic nods to America’s founding.  Marathon has been supplying the Department of Defense and various branches of the United States military with MIL-SPEC watches for many years, and the Pilot’s Navigator in particular has special resonance within their collection as it was originally developed in partnership with Kelly Air Force Base in San Antonia, TX in 1986. It’s a signature watch for Marathon and directly tied to the Canadian brand’s longstanding relationship to the American military, so it serves as a natural canvas for a limited edition.  Various aesthetic features of the new Anthracite Stainless Steel Pilot’s Navigator have been inspired directly by the U.S. flag and the Star Spangled Banner. According to Marathon, the anthracite stainless steel case (coated in black ion-plating) is inspired by the line “the twilight’s last gleaming” in the national anthem. Similarly, the single red tritium tube at 12:00 is a reference to “the rockets’ red glare”. Lastly, a “1776” stamp can be found on the dial just under 12:00. It’s circled by stars, and a visual refer...

Marathon Expands the Anthracite SAR Collection Worn & Wound

Marathon Expands the Anthracite SAR Collection

Like the now-ubiquitous diver and pilot styles, the mil-spec field watch is experiencing a moment in the sun. The appeal is easy to understand: much like how the original Willy’s Jeep took to post-war civilian life by offering cheap, rugged, and reliable transportation, the military-styled field watch offers significant toughness while keeping functionality simple and usable for everyday telling. Put simply, it’s a romantic promise of adventure and bravado, scaled down to wristsize. Canadian watchmaker Marathon has been making mil-spec timepieces since WWII, and has offered tactical variants like the 41mm Anthracite GSAR for those looking for that covert ops image; the new 46mm Anthracite Jumbo Day/Date, and the 36mm Anthracite MSAR Auto straddle that original model in the Anthracite lineup, and offer further complications for the enthusiast audience. The two new models in the Anthracite Search and Rescue (SAR) Unit borrow heavily from their 41mm predecessor in both styling and construction. Both feature a 316L stainless steel case with titular Anthracite finish, a uni-directional bezel, a screw-down crown, and tritium gas tube and MaraGlo luminous numerals, hands, and markers. Visually, the watches look very similar; Marathon’s legible and surprisingly un-aggressive typefaces keep the white numerals crisp and clear against the black dial. The overall styling is complicated but not visually distracting, an important aesthetic facet for a field watch.  On the 46mm mo...

The Wild Watches of German Polosin SJX Watches

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...

IWC Releases a Titanium Mark XX in Petronas Colors Worn & Wound

IWC Releases a Titanium Mark XX in Petronas Colors

IWC holds a special place in my heart. One of my first “ultra-performance” sports watches was an IWC Aquatimer GST on a matching titanium bracelet. This was a 2000-meter water-resistant dive watch that featured a push-down locking unidirectional bezel and a mix of Luminova and tritium luminescence. This was in the late 1990s, and shortly after, I was tasked with reviewing their new IWC TZC UTC Pilot Watch, reference 3251. This model featured a sublime 5-piece bracelet with a push-button easy link removal system still in use today. It also had a display opening on the dial indicating a second time zone. Over the past twenty years, I have had the opportunity to get to know many IWC watches. Last year, one of their releases particularly caught my attention. While their pilot series has generally been quite conservative, they have recently experimented with different dial colors, but nothing like this release. As a Mercedes F1 team sponsor, IWC released a Petronas-AMG-themed Pilot Chronograph featuring bright Petronas green dial accents. This was a 41mm version of their standard day-date chronograph featuring their in-house caliber 69385 automatic movement in a grade 5 titanium case. For 2025, IWC has released the Mark XX Mercedes-AMG PETRONAS, essentially a time-and-date version of their previously issued chronograph. This one also features a grade 5 titanium case, but this time with a solid case back. Dimensions are 40mm across the case, with a slender height of only 10....

Marathon Introduces a New Steel Navigator with an Automatic Movement

If you want immediate Watch Nerd cred with something coming in at around the $1,000 price point or less, there are a handful of options for any budding (or experienced) watch enthusiast. Seiko, of course. G-SHOCK, too. And you can have your pick from many great microbrands, including Lorier, Baltic, and Brew, and too many others to name. If your tastes veer toward the tactical, however, and you happen to be a lume connoisseur, Marathon is (somehow) still under the radar, makes a high quality, well designed watch that just about anyone who has been around the horological block will appreciate. Their newest release, an automatic version of their 41mm Steel Navigator, takes a classic Marathon silhouette and gives it an automatic movement.  Marathon has been manufacturing timing instruments of all kinds for various militatires since the 1940s, and the Navigator case, with its familiar asymmetrical shape, will scream “issued military watch” to many collectors. The original Steel Navigator traces its roots to the 1980s, when it was developed in partnership with Kelly Air Force Base for use by pilots. Everything about the design is function first – this is a pure tool watch if there ever was one. It’s got a 12 hour bezel for foolproof tracking of a second time zone, a two-tiered hour track with a 12 and interior 24 hour scale, a 41mm case crafted from stainless steel without a polished surface in sight, and, maybe most notably, an array of tritium tubes on the dial and h...

Porsche Design Chronograph 1 Gets Titanium Carbide Case Worn & Wound

Porsche Design Chronograph 1 Gets Titanium Carbide Case

The Porsche Design Chronograph 1 is among the great original chronograph designs to which the rules around aging just don’t seem to apply. Whether it’s the original and its many variations, or the modern reinterpretation, which we reviewed here, the Chronograph 1 is a benchmark when it comes to balancing form and function between the dial and case. Since re-introducing the Chronograph 1 in early 2022, a celebration of the watch’s 50th anniversary, Porsche Design has slowly been filling out the collection with interesting variations, largely in line with special releases from Porsche. This latest edition takes a different approach, recalling their past as a military watch, but with a civilian friendly nomenclature: Utility.  The newest addition to the Chronograph 1 collection recalls details from military watches of the ‘70s, with many of the small details represented in a slightly altered manner, from unit insignia, to the tritium marking “3H” circled in red – each are repurposed to create a new, more inclusive platform called Utility. Further still, this is more than a visual exercise as the biggest feature of the new watch is the use of titanium carbide for the case, a material developed and patented by Porsche Design. The material is touted as tougher and lighter than what we presume is the titanium variation of the watch, with a titanium glass bead blasted finish on its exterior. The light gray, matte appearance is uniform with contrasting crown and push...

Ball Engineer Hydrocarbon Original 40mm Hands-on Review

What we like: Great looking watch with solid engineeringExcellent fit and finishComfortable on the wrist What we didn’t : Crown guard may feel fiddly for day-to-day useSharpish edges on the claspNot the easiest watch to change straps Overall rating: 8.125 /10 Value for money: 7.5/10 Wearability: 8.5/10 Design: 8/10 Build quality: 8.5/10 First things first. Let’s all get our minds out of the gutter and leave the crude, juvenile schoolyard jokes behind. We’re better than that. Aren’t we? Yes, I get that jokes about balls are just too easy and we should all rise above it and move on to more sophisticated humour. Probably. Ball watches may not be front of mind for the vast majority of us considering a watch purchase, but it really shouldn’t be overlooked… once you get past the name… Yes, I know what I typed just in the previous paragraph. But it’s just too easy. As the size of your balls, all the best quality of the watches are hidden, away from prying eyes. But once you dive deeper you’ll see that perhaps these inner qualities are worth a second glance. Or three. To be honest, much like the rest of you, I’ve not given the Balls a second glance. Even though I’ve known about the brand for a long time, the only thing that I knew about them was their glow-in-the-dark capabilities, thanks to their tritium gas tube technology. Other than that, to me, they were just another brand utilising reliable workhorse movements from ETA/sellita, but not much else stood o...

Introducing the Blancpain Fifty Fathoms No Rad SJX Watches
Blancpain Fifty Fathoms No Rad Mar 16, 2021

Introducing the Blancpain Fifty Fathoms No Rad

Blancpain’s iconic dive watch introduced in 1953, the Fifty Fathoms was named after the maximum depth then considered to be safe for divers, about 91 m. The Fifty Fathoms also claims the title of being the first purpose-built dive watch, though Rolex contends that its Submariner came first. Produced in a great many iterations, the Fifty Fathoms has become highly collectible in good number of variations, including those bearing the “No Radiations” logo – used in the early 1960s to indicate that radioactive radium was no longer used for the luminescence of the dial. That watch has now been revived by Blancpain as the Tribute to Fifty Fathoms No Rad, a limited edition that channels the spirit of the 1960s original, but executed in modern-day Blancpain quality. An example of the vintage Fifty Fathoms “No Radiations” Initial thoughts A staple of Blancpain’s line up, the Fifty Fathoms has been revived in various guises over the last few years, with the latest “No Rad” being the latest of several vintage remakes. The abundance of Fifty Fathoms limited editions – all similar but slightly different – have diminished its uniqueness somewhat, but the “No Rad” is nonetheless compelling. For one, the design has some provenance: the vintage “No Radiations” is a rare watch that’s exploded in value on the secondary market. And the “No Radiations” dial is quaint and quirky, but also historically significant in the transition from radium to tritium, c...

H. Moser & Cie. Introduces the Vantablack Black Hands SJX Watches

H. Moser & Cie. Introduces the Vantablack Black Hands

On April Fools’ Day last year, H. Moser & Cie. published a doctored image of a watch with an all-black dial missing hands, a riff on its watches with blacker-than-black dials. The hoax watch turned into something of a hit, which has led to the latest trio of limited editions, the Vantablack Black Hands – which will also be available online directly from the brand. All three watches – ranging from a stainless-steel base model to a limited-edition tourbillon – feature dials coated in Vantablack, a high-tech coating that absorbs almost all incident light – making it extremely and almost absolutely black – matched with black-coated hands. Because the coating on the hands is more of a dark grey, and also glossy, the hands do actually stand apart from the dial, appearing to be suspended in nothing because the dial is so black. The Endeavour Tourbillon with the reflection being on the crystal, rather than the dial Venturer Vantablack Black Hands XL in steel Invented by a spin-off from the University of Surrey in the United Kingdom, Vantablack is made up of carbon nanotubes arranged vertically, like a surface covered in really fine fur. The carbon nanotubes absorb 99.965% of incident light, resulting in a surface that resembles a deep, dark hole, which is an quirky and strangely appealing finish for a watch dial. Even though other substances are even blacker than Vantablack – with the record held by an MIT invention from 2019 –  Vantablack is the best-known...

Panerai Introduces the Luminor Marina Carbotech PAM 1661 SJX Watches

Panerai Introduces the Luminor Marina Carbotech PAM 1661

Three years ago, Panerai introduced the LAB-ID Luminor 1950 Carbotech 3 Days PAM 700, an experimental watch boasting carbon-based innovations inside and out, including ceramic bridges and plates that do away with jewelled bearings as well as a dial coated in carbon nanotubes giving it an absolute black finish. But the LAB-ID was truly experimental, and word has it that only a handful were sold and the planned 50-piece run was never completed. But no doubt due to the popularity of the LAB-ID’s design – and unpopularity of the €50,000 price tag – Panerai has just announced the Luminor Marina Carbotech 44 mm (PAM01661). It’s essentially a smaller, simpler LAB-ID, featuring a case in the same material, as well as blue lume on the dial and hands, but with a straightforward automatic movement without any of the bells and whistles found in the LAB-ID. The Luminor Marina Carbotech 44 mm Depth rated to 300 m, the case is made of Carbotech, a carbon fibre-reinforced polymer produced by compressing thin sheets of carbon fibres at high pressure with a high-end polymer (PEEK), explaining the wave-like appearance of the material. The result is a material that is light and strong, explaining why the large, 44 mm case weighs just 96 grammes, less than half the same case in steel. The LAB-ID of 2017 The watch has a standard Panerai dial, but in the colours of the LAB-ID. Like most Panerai dials, it has a “sandwich” construction, where the hour markers are cut-outs that r...
