A History and Guide - How to Use a Dive Bezel

John Scott Haldane had a problem. Britain’s Royal Navy had commissioned the Scottish physiologist to find a solution for a unique problem facing their divers: decompression. Known since the mid-19th century, decompression sickness (DCS) posed a serious risk for divers and laborers working in pressurized environments, such as caissons. It was his job to develop a set of decompression tables for safe diving operations. It boils down to how gases act under pressure. When breathing a gas mixture at depth - for the sake of simplicity, we will say compressed air, or approximately 78% nitrogen and 21% oxygen, with the rest being inert gases - the oxygen is used up by the body, and the nitrogen is absorbed into the bloodstream. This build-up will dissolve as it is effectively off-gassed, as it does when each of us breathes here on the surface. Enter pressure. Should a diver undergo a rapid change in pressure, such as by ascending too quickly, the nitrogen will separate from the blood and form bubbles in the tissues and joints. The resulting pain has a habit of contorting its victims, giving DCS its more readily-known nickname of “the bends.” John Scott Haldane had a problem.

Bulova Jet Star Review: Retro Design Meets Cutting-Edge Precision

The Bulova Jet Star is one of those watches that leaves no room for doubt as to the decade from which its distinctive design originates. Revived in 2023 to commemorate the original's 50th anniversary, in a trio of diverse colorways, all the modern Jet Star models vibe “‘70s throwback” in a major way, with their unconventional, turtle-shaped cases and boldly colorful dials. However, they’re also very avant-garde in ways that their predecessors simply weren’t able to be, particularly in their use of Bulova’s high-frequency Precisionist calibers, their elevated level of finishing, and the almost three-dimensional degradé effect enhancing their dials. Scroll down for a closer look at each of the 50th anniversary Bulova Jet Star watches. Bulova Jet Star Case And Bracelet The modern Jet Star case is more angular and multifaceted than the curvilinear “turtle” shape of its 1970s predecessor. Strictly speaking, the case is octagonally shaped and topped with a round bezel that hugs the domed sapphire crystal. Measuring 40mm in diameter, approximately 45mm lug to lug, and 12.5mm thick, it boasts an array of polished and brushed finishes that accentuate those multiple, subtle edges and surfaces and lend the Jet Star an air of luxury in addition to its unmistakable retro charm. The lugs themselves are relatively short, with a 20mm lug width to accommodate the bracelet (on the two steel versions) or strap (on the gold-tone model and the steel limited edition). The crown...

Rolex Ventures Into Cutting-Edge Atomic Timekeeping

In a surprising move from the conservative watchmaker, Rolex has quietly set up Rolex Quantum SA, a new entity dedicated to atomic timekeeping, the most precise form of timekeeping ever invented by man. Rolex chief executive Jean-Frederic Dufour will sit on the board of Rolex Quantum, with engineer Fabien Droz serving as director of the venture. With Rolex Quantum, the watchmaker plans to develop and sell atomic clocks, conceivably for industrial or scientific purposes. Being somewhat removed from the core Rolex offering of wristwatches, the atomic clocks will be developed separate from the main Rolex brand. The new venture strengthens the brand’s ties with CSEM (Swiss Center for Electronics and Microtechnology), the Swiss technical institute most famous in watchmaking for having developing silicon component for watch movements. The venture will benefit from Rolex’ broad industrial research and development capabilities, while also leveraging CSEM’s experience with atomic timekeeping. The establishment of Rolex Quantum was first reported by Swiss newspaper Arcinfo. Neuchâtel timing Despite the cutting edge nature of its work, Rolex Quantum will be located on historic grounds, namely on the same street as the Neuchâtel Observatory, which is current home to CSEM’s atomic timekeeping laboratory. The location also has historical resonance as the city has long played a role in watchmaking and chronometry over the years. Abraham-Louis Breguet was born there and the obs...

Doxa Adds a Steel Bezel to the SUB 200 Diver

Doxa added a GMT to their collection for the first time in years to much fanfare recently (we covered it here). This watch got quite a bit of press and stirred considerable interest within the enthusiast community, but to my mind it was only the second best watch the brand showed us when we met with them in Geneva last month (that’s second out of two, just to be clear). I’m not sure what it is, exactly, but I’m a little over the whole “put a GMT on it” approach to product development that the industry has been stuck in for the last few years. Do we really need the ability to track two or more time zones on every watch? And should we really be doing it with movements that perform this function almost by accident and are nearly impossible to use correctly if you’re actually traveling? I’m trying not to be a hater, really I am, but every time I see a new GMT equipped watch that’s just a riff on an existing diver or chronograph, as if a GMT complication is just an extra side on a barbecue platter, I ask myself what it is that we’re doing here, really.  A new version of the Doxa SUB 200 was the other watch Doxa was showing in Geneva last month, although it was embargoed until last week, so I couldn’t come out of that meeting with the blistering hot take that it actually makes a lot more sense as a watch than the SUB 250T GMT, which to me feels like something ChatGPT might invent if you asked it to think of Doxa watches that don’t yet exist. This SUB 200 i...

Timekeeping at the Edge of the World: Four Watches Across Iceland

Iceland is a place of extremes: glaciers, geothermal hot springs, and black sand beaches shaped by volcanic fury. It’s also a place where time seems to slow down and I thought it was ideal for reflecting on both nature and time spent with family-shaping memories I'll never forget. Watches were also part of the journey, of course. And as I prepared for the trip, the exercise behind choosing which timepieces to bring was something I deeply enjoyed. Now that I'm back, I just wanted to reflect on those choices and how they played a role in my first trip outside the US since the COVID era. I needed it, and it was awesome.

The New Casio Oceanus Pays Tribute to the Deep Blue Sea with Spiral-Cut Sapphire Bezel Anchored by Hardened Titanium Case and Bracelet

The Oceanus might be the last thing you think about when you hear the brand name, Casio. Their elevated range of watches aren’t built with the familiar tough resin case accompanied by a soft urethane band and a digital display. Instead, Casio has elected to encase the Oceanus with titanium paired with distinguishable features that stray away from the utilitarian feel while still integrating their technological know-how in a more analog fashion. In short, this concept is what Casio refers to as, “Elegance, Technology”. The four latest additions include a limited reference and three regular production models that harness the dynamic cerulean hues of the ocean packaged in a coated titanium case and equipped with a suite of familiar features. Like the Manta S500 Series, the Oceanus OCWS6000SW2A takes the bezel and uses it as a canvas to uniquely represent the various features of the ocean. This limited production model in particular displays the movement of the ocean with a spiral-cut sapphire bezel representing the crest and trough of a traveling wave. The blue gradient of the bezel also gives the impression of the continuous motion of the ocean. Although masked by color, the sapphire bezel still allows light to penetrate through, powering the solar panel fixed beneath. As mentioned above, the case is constructed out of titanium and coated with a carbide treatment giving a powdery, sandblasted effect across the non-polished areas. Another distinguishable feature of the ...

Ollech & Wajs’ Astrochron S Combines a 500 WR Dive Chronograph with a Compass Bezel and Regatta Counter

If I had a time machine to visit any point in history, my adventurous spirit would punch in the year 1969. This was already a period rich with daring exploration, technological innovation, and historical achievement that inevitably led to the culmination of the Space Race with NASA putting a man on the moon. But that wasn’t the only “high stakes” race going on at the time. Watch brands all over the world were jockeying for position to see who could make the most robust tool watch for explorers foraying into the most extreme conditions including the unknown depths of the ocean, mountainous death zones, and of course, outer space. Ollech & Wajs was one of the brands that were most certainly in the mix with their own multi-functional triple register chronograph aptly dubbed the Astrochron. The Astrochron’s distinctive multi-scale display made it a popular choice among engineers and scientists in NASA’s research and development lab including Chief Rocket Scientist, Werner Von Braun, or otherwise known as the “father of space travel.” Equipped with a rotating 12 hour bezel, tachymeter scale on the dial, chronograph timer, and a slew of other attractive tool watch features, the Astrochron found its way onto the wrists of sportsmen, pilots, and ship officers alike. Recently, Ollech & Wajs has decided to revisit the design and one glance will confirm that this isn’t your original 1967 Astrochron. With the new refresh, Ollech & Wajs’ already capable multi-function...
