Why I Bought A Third-Generation Omega Seamaster Planet Ocean 600M Over The New Version
Recently, I bought an Omega Seamaster Planet Ocean 600M with a 43.5mm all-brushed steel case and a sandblasted gunmetal-gray dial. This purchase came after the launch of the fully revamped Planet Ocean. With the fourth generation’s sharper facets, redesigned bracelet with polished center links, slimmer profile, and importantly, no helium escape valve (HEV) at the […] Visit Why I Bought A Third-Generation Omega Seamaster Planet Ocean 600M Over The New Version to read the full article.

Seiko Marinemaster SJE101 Review: Divisive But Wears Like A Dream
The Seiko Prospex Marinemaster SJE101 1965 Diver’s Modern Reinterpretation is definitely a mouthful, but it’s definitely with purpose. Part of the higher-end Seiko Luxe family, the SJE101 evokes two icons - the 62MAS and Marinemaster - but can it live up to those lofty expectations? The answer, as you can imagine, is mixed. What’s for sure, though is that this is a uniquely wearable Seiko Prospex dive watch that measures less than 40mm and has some really impressive finishes. That said, the Marinemaster title carries a lot of expectations with it, and there has been a fair share of discourse about whether it lives up or not. Seiko Marinemaster Context What exactly is the big deal with the Seiko Marinemaster? Let’s take a look at how it came to be such a lauded name in the diver category. The first watch in the collection was actually the Seiko Marinemaster Quartz SBCN005, aka the Transocean from 1999. This was a 44mm-wide titanium watch that was highly functional with barometric pressure measurement and barometric trend display. A year later in 2000, the Marinemaster SBDX001 was released, boasting 300 meters of water resistance and no helium escape valve. The Marinemaster family would continue in production until about 2018, when it began to disappear in favor of the larger Prospex family. But about five years later, the Marinemaster would come back in the form of this collection. More than a couple of people have asked whether this is “really a Marinemaster...

Deeper, Further, Faster: Why do Some Dive Watches have Helium Escape Valves?
Humans have long had a fascination with the depths of the ocean, striving to go ever deeper, ever further, and ever faster by pushing the limits of the human body, technology, and advancing modern science. But like all things, we are often faced with limits. And the helium escape valve was invented to push one of those limits as watchmaker Ashton Tracy explains.

Tudor Pelagos 39 Review
Back in 2012, Tudor unveiled its action-ready diver, capable of surviving depths up to a whopping 500 meters (that’s over 1,640 feet) with the Pelagos. To achieve that extensive depth rating, for many, the necessary tradeoff came with the 42mm sizing that the Pelagos debuted, which is the caveat made with the inclusion of a helium escape valve to make the case more secure in deeper diving excursions. In the years since its release, Tudor has riffed upon the Pelagos in various ways, even including teaming up with the French Marine Nationale to create the FXD extension on the line, and recently, throwing in a GMT complication into the mix. And let's not forget this year's Pelagos Ultra. But we are gathered here today to take a good, long look at the Pelagos many asked for, with the more versatile-sized Tudor Pelagos 39. Despite listening to the audience and essentially delivering what they ordered on a silver platter, the Pelagos 39mm has largely remained in the shadow of the brand’s golden child, the Black Bay 58. When comparing the two, there’s a lot of common ground between the two watches on the surface: they’re of comparable size (the Pelagos 39mm is actually .1mm slimmer), identical levels of water resistance at 200m, and the price difference between the two is under $1,000, which doesn’t seem incredibly significant given the Pelagos 39mm is all in Titanium, which always more costly. So, what is the secret sauce that the Black Bay 58 has that the Pelagos lack...

Tudor Pelagos Ultra Review
The Tudor Pelagos has consistently been something of "the other watch" in the broader Tudor lineup, sitting in the shadow of the Black Bay. It is also decidedly more modern in its design and is intended as Tudor’s more contemporary, dive-ready tool. What started as a 42mm mode then morphed into a watch in varying sizes, lug construction, and case construction. In 2025 it now sits as a somewhat diversified collection of its own. Is it a Black Bay in terms of scale and breadth of the collection? No, it is not, but it is also no longer a one trick pony. That concept is no more evident than in the Watches & Wonders 2025 release of the Pelagos Ultra, a 43mm riff on the Pelagos theme that aligns it more closely with the Rolex Deepsea than the Sea-Dweller or Submariner. This is a big, brash, and burly dive watch, intended for a very specific segment of the watch world. If you thought the Pelagos FXD was specific, the Ultra turns the dial up to 11. Case So as I mentioned above, the case is made from the traditional (for a Pelagos) titanium material, a combination of grade 2 and grade 5 to be specific. The side of the case opposite the crown features a discreet helium escape valve. The case may seem big from the specs alone, but the 52mm lug-to-lug makes it such that it isn’t a behemoth. The case thickness is a proportional 14.5mm and due to the overall size, you will be looking at a lug width of 22mm. The bezel insert is made of a matte titanium housed in a titanium bezel. The...

Omega Unveils Seamaster Planet Ocean Worldtimer
Omega’s latest is an unusual combination of a 600 m-rated dive watch with a Cottier-style world time. The Seamaster Planet Ocean Worldtimer shares the oversized ceramic case of the Planet Ocean Deep Black, but is the first model in the collection to incorporate a world time complication. Initial thoughts While the Worldtimer makes a bold statement, a US$14,800 price tag and substantial case dimensions may limit its appeal – particularly for those with average-sized wrists. Still, it offers a somewhat paradoxical and oddly specific combination of features, so someone seeking a world time watch ready for saturation diving, there are few other options. Of the two available colourways, I would choose the low-key grey edition for its greater versatility compared to the turquoise version. Worldtimer Offered with either turquoise or grey accents, the new Planet Ocean is housed in a black ceramic case measuring 45.5 mm in diameter and 17.4 mm in thickness. Signature Seamaster case elements, including twisted lyre lugs, a helium escape valve, and “Broad Arrow” hands, complete the design. The standout feature the world time complication with a cities disc and 24-hour ring. At the centre is a titanium disc displaying a view of the Earth from the North Pole, with continents and colours rendered with varnish and laser engraving. A 24-hour ring in transparent hesalite is shaded in black and white to denote night and day. The chapter ring for the hours is embellished with a honey...

Micro-Brand Digest: A Selection of Cool Divers, a Dial Made from a Demolished Bridge, and a Young (Very Young) Watchmaker to Keep an Eye On
Welcome to the Worn & Wound Micro-Brand Digest, a semi-monthly roundup of all the new micro-brand news we’re following, from concepts that show promise, to Kickstarter launches to restocks, and everything in between. Small independents, and affordable micro-brands spurred the creation of Worn & Wound over 10 years ago, and they still drive our enthusiasm in a big way. Here’s what’s caught our eye this month. If you’ve come across a project you think qualifies, hit us up at info@wornandwound.com for inclusion. Supra Rub Having grown up in the south of France, surrounded by fishermen, sailors and divers, Supra Rub’s founder was frequently regaled by stories of unusual journeys and adventures. Epic tales of freedom and the courage to face the seas. That is when he noticed that all these men had one thing in common: a reliable, robust, and well-worn watch on their wrists. He understood then that not all watches could withstand these hostile environments and that is how his two passions were born. The Sea and the world of watches. With the creation of his brand Supra Rub, he is merging these two passions to offer his inaugural watch, the Aurora, named after his grandfather’s fishing boat. More than the sum of its parts, the Aurora is quite the dive watch. Made entirely of 904L stainless steel, which has higher corrosion resistance than standard 316L. It features a flush mounted automatic helium escape valve; it is water-resistant to 300m and has a ceramic unidirecti...

Nubeo Introduces a Collection of Fun, Colorful Divers with Impressive Specs
Nubeo is a brand that takes its inspiration from both sea and space in tribute, in function and in design. Their latest dive watch is named after the Ventana remotely operated vehicle. This scientific submersible is rated to a depth of over 1700 meters, and for 30 years and somewhere north of 4,100 dives it is the most experienced and enduring ROV in the world. This diver sure looks the part and with 1000m of water-resistance, it can also do the part. The perfectly round stainless steel case is a whopping 50mm in diameter, but similar to everyone’s favorite Japanese dive watch nicknamed after a delicious sandwich fish, there are no lugs. The strap directly attaches to the watch underneath each side, in a hooded fashion. Therefore, despite its girth, just about anyone should be able to wear it. All of the Ventana variants feature a deep wave patterned dial, with a flush helium escape valve at 9 o’clock and, believe it or not, a captive bezel held in place by large screws. The extra-large hands and indices, along with the oversize bezel pip are filled with a copious amount of lume. Powering the Ventana is the automatic, Seiko built, NH35 movement, and all come on a specialized, thick silicon strap, ready for action. Finishing the year with a bang, Nubeo has introduced 4 new colorways, each limited to 400 pieces. First there is the Basalt Grey, for those that prefer a more conservative look. Its bezel insert is a half-half split of black on top and, as the name implies, g...

Review: the Circula DiveSport Titanium
Roughly 20 years ago, I was tasked by my editor and Baume & Mercier to review the latter’s latest, toughest tool watch. I know what you are thinking. Baume & Mercier and the words “tool watch” do not go together. Well, for a brief period, the appropriately named Capeland XXL was just that. This was a large titanium dive watch, with a striking yellow patterned dial, with oversized hands and a helium escape valve. It was such a departure from their norm and boy, was it a super cool watch. Fast forward to today and I have another super cool titanium, yellow dialed diver to review, the Circula DiveSport. Circula has been around since 1955, founded by the current owner’s grandfather Heinz Huber. Based in Pforzheim, Circula shares a hometown with Aristo, Laco and Stowa, as well as renowned case maker Fricker GmbH. Circula has been rejuvenated as of late, with Cornelius Huber now at the helm. Their previous models leaned heavily on classical designs from yesteryear and just like the Capeland XXL, the new DiveSport is a departure from the norm. From the design to the materials, this one is fully modern and has its sights on the future. The DiveSport’s multi-faceted grade 2 titanium case measures 42mm in diameter, with a lug-to-lug length of only 48.5mm and it is 13.4mm slim (+0.5mm with the crystal). Why did he say slim, you may be asking, as 13.4mm does not sound that thin. It is if you consider the 500m depth rating! Also, when you combine the 133g weight (with 2 l...

Zodiac and Huckberry Introduces a Wildly Capable LHD Super Sea Wolf Pro-Diver with a GMT Hand and HEV
If you were tuning into our feed at the beginning of the year, we published an article where the entire Worn & Wound editorial team gave their predictions for what they thought would happen in the watch industry in 2023. Given the growing amount of watches with a GMT complication we saw released towards the latter part of the year, I started my portion of the article with a bit of an obvious take – 2023 will be the Year of the GMT. And so far, it has been. I’ve written about six different GMT’s since we’ve crossed over into the new year and I don’t expect that to trend in the other direction any time soon. In addition to my soft ball of a prediction, I did “hope” to see more options with a slight change to the GMT format this year, where a dive watch design is put first, and then the travel component second. A Diver-GMT, if you will. Well it seems that Zodiac has gotten that memo. The latest addition to the Diver-GMT space is the Zodiac LHD Pro-Diver GMT. Zodiac has taken their core professional dive watch with the Super Sea Wolf Pro-Diver, switched up the crown placement, added a fourth hand to track a second time zone, and added a helium escape valve for good measure. The Zodiac LHD Pro-Diver GMT is all business. Usually we’re used to seeing fun dial and bezel color combinations from the brand, but this new release is entirely the opposite. Aside from the splash of color from the orange accented GMT hand, water resistance rating on the dial, and the tri...

Omega Introduces the Planet Ocean Ultra Deep 6000 m
Omega has just taken the covers off a slew of new watches for 2022, but the standout is doubtlessly the Seamaster Planet Ocean Ultra Deep 6000 m. The Ultra Deep began with a trio of experimental Ultra Deep watches that completed a 12-hour dive strapped onto the exterior of a submersible, reaching 10,935 m, or 35,876 ft, the deepest any human or watch has ever dived according to Omega. The experimental watch – which was rated to 15,000 m – has evolved into the commercially-available Ultra Deep, which is Omega’s capable dive watch. While having half the depth rating of the experimental model, the Ultra Deep 6000 m is much more wearable with a diameter of 45.5 mm, similar to that of a Planet Ocean 600 m, albeit with a case thickness of 18.12 mm. The experimental watch, on the other hand, was almost 28 mm thick. And needless to say, the Ultra Deep is a saturation diver’s watch, but one constructed impermeable to gases, explaining the lack of a helium escape valve. Initial thoughts Omega’s top-tier dive watches have always been thick, but the Ultra Deep takes it to the next level. With its enormous case, the Ultra Deep is probably not very wearable, but that’s an integral feature of a dive watch like this. It is so overbuilt that it doesn’t really make sense, but that’s what makes the Ultra Deep cool. While the technical achievement of the depth rating is impressive, the Ultra Deep is notable for more than just raw numbers. Among its novel features is O-Megast...

Hands-On: Bell & Ross BR 03-92 Diver
Launched two years ago with a steel case, the BR 03-92 Diver took the signature aviation inspired design of Bell & Ross (B&R;) into the sea. It was a proper dive watch that combined the iconic square case with a 300m depth rating and a rotating bezel. At Baselworld this year, B&R; unveiled two new iterations of the BR 03-92 Diver, with cases in bronze and matte black ceramic respectively. Though fundamentally identical, each is drastically different from the other in look and feel. The road to the deep But first a quick recap of B&R;’s past dive watches. Though the brand is today best known for its military aviation watches, B&R; got its start making watches (which were essentially rebadged Sinn timepieces) for professionals in various spheres, from bomb disposal engineers to deep sea divers. One of its earliest dive watches was the Hydromax (also known as the Hydro Challenger) of 1997. It was a compact, round watch with a quartz movement boasting a ludicrous depth rating of 11,100m, thanks to a case filled with transparent fluorinated oil that was incompressible. A decade later, the brand was producing its own watches and unveiled the BR 02, a tonneau-shaped dive watch with a 1000m depth rating, internal rotating bezel and helium escape valve. Then came the BR 03-92 in 2017, the most logical expression of a dive watch for a brand driven largely by military-inspired design. Crucially, bona fide square watch cases are inherently more difficult to seal against ...

In-Depth: Orient Star’s Smart Silicon Escape Wheel
While silicon mechanical movement components have swept across Switzerland, adoption has been slow within the Japanese watch industry, stymied by Swiss patents and professed concerns over the material’s durability. To this day, it remains the unlikely domain of Orient Star, a small brand with priority access to Seiko Epson’s massive industrial base. This positions Orient Star to capitalise on consumer demand for increasingly long power reserves, without sacrificing performance. Thanks to an ultralight and geometrically efficient escape wheel with a patented design, Orient Star is able to deliver a 70-hour power reserve without resorting the same counter-productive trade-offs to balance energy made by some Swiss peers – here’s how it was done. A silicon wafer of escape wheels. Image – Seiko Epson The quest for longer power reserves Recent consumer demand for longer power reserves has sent the industry’s engineers scrambling for ways to increase the autonomy of existing movement platforms. A movement’s power reserve is dictated by the length of the mainspring, which unwinds at a constant rate. That is why using a chronograph doesn’t cause a watch to run down faster – usually. Of course, you need to find somewhere to fit that extra length of mainspring while maintaining the movement’s dimensions, such as by thinning out the barrel walls, narrowing the inner barrel arbour radius, or, reducing the thickness of the mainspring. However, while decreasing the ma...
