Watch Bezels: Every Type Explained

If you’re new to your appreciation of fine watches, you have undoubtedly read a lot of references to and heard a lot of opinions about watches’ bezels. It is somewhat of an esoteric term but it describes something very simple and essential. The bezel is the front part of the case (often but not always ring-shaped) that frames the dial and secures the crystal. Bezels can be made of the same material as the case middle and/or the caseback, but can also be made of a different material. Here we run down the various types of watch bezels you’re likely to encounter. Polygons and Exposed Screws Watch cases, of course, are not uniformly round, which means that bezels, the front-facing parts of those cases, can also be found in a variety of shapes - sharply squared or rectangular, like the Cartier Tank and Jaeger-LeCoultre Reverso (above); softy cushion-shaped, like the Panerai Luminor and Vacheron Constantin Historiques American 1921; oval-shaped, like the Breguet Reine de Naples and other luxury ladies’ models; tonneau (“barrel”-shaped), like the Hublot Spirit of Big Bang and many Richard Mille models; and a host of others that combine elements of these and other polygonal shapes.  The shape that has proven to be the most popular and influential is the octagon: eight-sided bezels have proliferated ever since Audemars Piguet launched the Royal Oak (above) in 1972, and watchmakers have also dabbled in other unconventional shapes: the sharply faceted bezel of the Zeni...

Omega Introduces the Constellation Gents’ 41 mm with Ceramic Bezels

One of the longest-lived models in the Omega line up, the Constellation with its characteristic “claw” bezel made its debut in 1982 as the Constellation Manhattan. Still looking like a 1980s design many years after that, the collection was face-lifted this year and given a smart new look that retained all of the key elements but with tighter, more modern lines. Now Omega has just taken the covers off the flagship men’s model, the Constellation Gents’ 41 mm that features an unusual combination of a metal case, polished ceramic bezel, and an integrated strap or bracelet. Initial thoughts Offered in a variety of striking dial and bezels combinations – with the red gold and blue ceramic being the most striking – the latest Constellation is the most noteworthy of any recent model. Despite the number of iterations, each model has a cohesive look with all the elements complementing each other. My favourite is undoubtedly the steel version with a irregularly textured dial thats adds visual appeal and intricacy compared to its counterparts with simpler dial finishes. Regardless of iteration, the new Constellation also has a slightly sporty look that is appealing, unlike earlier attempts at a sporty Constellations – like the chunky Constellation Double Eagle – that fell flat. Overall its a good-looking but affordable luxury-sports watch in steel And it does look much better in 18k gold, but then it costs three times as much. Shiny ceramic What makes them special a...

Yet despite many decades of looking up to aviation for clues, very few modern pilot watches can actually assist pilots in flight procedures. Most are stylistic […]

Seiko Adds New Seiko 5 References with Compass Bezels

Every watch enthusiast has gotten the question from a newly watch-curious friend: “what should be my first real watch?”  Of course, designating any watch as “real” over another is a bit silly, but the sentiment remains. For newbies to the horological hobby, there are few “first” watches better than any model from the ever-expanding and always-iconic Seiko 5 lineup. From skin divers to field watches and way beyond (especially if you look at vintage…), there’s a Seiko 5 for everyone, and not just new fans, either. Most serious enthusiasts can attest to having a 5 in their collection, or at least having owned one (or many) in the past. So, when Seiko comes out with a new 5 entry, it’s hard not to be excited, and four new Seiko 5 Field models have arrived to continue that tradition. The HDB006, HDB007, HDB008, and HDB009 bring a lot of the hallmarks of Seiko 5 field watches, including wearable dimensions at 41mm in diameter and 13.2mm in thickness, strong LumiBrite coating on the hands, indices, and bezel markings, and trademark Seiko robustness and reliability thanks to the 4R36 caliber automatic movement, which provides 41 hours of power reserve, a stop second hand function, and a day/date complication. While none of these features are particularly remarkable or innovative, they prove the everlasting utility of a field watch as an everyday timepiece. The new HDB00- models do have an extra party trick up their sleeves in the form of a simple compass on the ...

A Charming Tribute to the Analog Life: Introducing the Xeric Omnigraph Automatic

Somewhere, in a drawer lined with yellowed graph paper and sharpened No. 2 pencils, there’s a circular slide rule waiting to be understood. It belonged to a grandfather who spent his life chasing the elegance of equations-someone who could balance a checkbook in his head and chart a rocket’s trajectory on a napkin. For the person who inherited that drawer-and the curiosity that came with it-the new Xeric Omnigraph Automatic feels less like a watch and more like a reunion.   Before computers, before calculators, before “Hey Siri, what’s 38 times 72?”-there was the circular slide rule. It wasn’t just a tool; it was a visualization of thought, an instrument for those who found beauty in precision. Xeric’s Omnigraph takes that analog intelligence and transforms it into a timepiece where mathematics itself becomes the design language.     The post A Charming Tribute to the Analog Life: Introducing the Xeric Omnigraph Automatic appeared first on Worn & Wound.

Laco Introduces the Atacama Quartz UTC, a True Tool No Matter How You Slice It

Doomsday preppers and the most hardcore of watch collectors are in for a real treat. German watch manufacturer Laco is doubling down on the success of its Atacama.2 by introducing the Atacama Quarz UTC. It’s a more affordable and focused watch with a new trick up its sleeve: GMT functionality. Primarily known for their excellent pilot watches, Laco has collaborated closely with German soldiers, firefighters, and other action-oriented professionals to hone their “Squad and Sport” timepieces. It only takes a glance to understand. You can learn a lot about this watch in its name. It’s still an Atacama, which means it shares the same PVD-coated treatment, date complication, rubber strap, unidirectional bezel, and matte dial as the Atacama.2. But now it’s powered by quartz, “Quarz” in German, and features an independent GMT – or UTC – hand. The new watch is 46mm in diameter, but the Ronda 515 GMT quartz movement inside has enabled Laco to slim the watch down to 10.5mm with a “contact area” of just 34mm. This is also in part due to the conical shape of the case, allowing the watch to feel much smaller and comfortable on the wrist than its maximum diameter may suggest. The use of black PVD-coating and generous amounts of lume on the hands, dial, and bezel result in a watch that is supremely legible to its wearer while remaining subdued to would-be onlookers (or enemies). The crown at twelve o-clock is integrated into and protected by the articulating lugs. D...

Track Time With Three New Seiko Chronographs - Now In The Windup Watch Shop

There’s a place in any watch collection for a solid chronograph. There’s something so fun about having a little stopwatch on your wrist to track time. Even if you’re not using the commonly-seen tachymeter bezel to calculate speed, you’ll find yourself using it for countless tasks throughout the day. It can be really handy to know how long that meal’s been on the stove, or how long you’ve been letting that french press sit. Today, we have three new chronographs in the shop from Seiko. Two of the three feature quartz movements, while the other features a convenient and reliable solar chronograph.

Color Rules the Day with the New Art Dial Detrolas from Shinola

With generative AI slop permeating even our most sacred of artistic spaces these days (don’t Google “AI in museums”, it will ruin your day), any honest-to-god expression of creativity can feel like a breath of fresh air. Watches can be a great escape in this regard, and watchmakers, from industry heavy hitters like Swatch to beloved microbrands like Fears, have recently released pieces inspired by aesthetic movements to bring a little bit of artistic integrity to your wrist. Detroit-based watch brand Shinola is throwing their hat in the multi-colored ring with two new vibrant models in their Detrola collection, inspired by the annals of American midcentury art, and at a price point that should appeal to many. Let’s take a gander.  The Detrola line is Shinola’s premier “pop” collection, featuring colorways that are a little bolder than the usual fare. With a clean field-dress design ethos, each Detrola watch comes in at 41mm in case diameter, making them ideal for everyday wear. Materials vary across the lineup, and the two new Color Theory models both feature polished cream TR90 resin co-molded with a stainless steel core. A thickness of 9.72mm keeps the watches slim on the wrist, and while the longer lugs add a bit of presence, giving the models a 45mm lug-to-lug width and allowing for 20mm straps. It’s a simple silhouette that allows the dial design to set the pace aesthetically, which works in the Color Theory models’ favor.  Each of the two models s...

A Majestic Journey Through Clocks & Watches Made for Royalty: King Philip II of Spain and the Rise of a Dynasty that Ruled by the Clock

From the imposing astronomical clocks of Tudor England to the exquisite pendant watches of Victorian Britain, timekeeping has long been a symbol of power, prestige, and technological marvel within Europe’s royal courts. This new series explores the fascinating evolution of clocks and watches crafted specifically for royalty, tracing how these intricate masterpieces reflected the tastes, ambitions, and innovations of monarchs. Through the lens of craftsmanship, artistry, and historical significance, we reveal how these royal timepieces marked the passage of dynasties and empires. King Philip II (1527–1598) inherited a globe-spanning empire from his father Charles V and, after 1580, also ruled Portugal. A devout champion of the Counter-Reformation, he centralised government, built the vast monastery-palace of San Lorenzo de El Escorial, and presided over Spain’s political zenith. His court prized scientific instruments and clocks as emblems of order and piety. Philip was part of the great Habsburg dynasty and the son of the Holy Roman emperor Charles V. From time to time, the emperor wrote Philip secret letters, impressing on him the high duties to which God had called him and warning him against trusting any of his advisers too much. Philip, a very dutiful son, took this advice to heart. During his reign the Spanish empire attained its greatest power, extent, and influence, though he failed to suppress the revolt of the Netherlands and lost the ‘Invincible Armada’...

Reviewing The Longines HydroConquest 42mm Edition

With all the talk around the new Longines HydroConquest models, we thought it best to see for ourselves what the fuss was about. What We Loved The classic dive watch look The sliding micro-adjustment on the clasp Solid build quality What We Didn’t The longer lugs make it wear a little larger than the specs suggest The Bezel action could be a little smoother The sliding micro-adjustment could have 5 mm more worth (but I’m nit-picking here) Overall Rating: 9 / 10 Value for Money: 9.5/10 Wearability: 8.5/10 Design: 9/10 Build Quality: 9/10 Recently, Longines announced the new HydroConquest collection, and there was a fair bit of talk about the new pieces within watch circles. After all, the brand released a good-looking 300m dive watch in two sizes, several colour ways and two bracelet configurations, and all for A$3,375 or A$3,550 depending on the bracelet chosen. So, it was a watch we just had to check out in person. For this review, I’ll be testing out the 42mm model on the more traditional three-link bracelet, and in the blue colourway. Mario will be tackling the 39mm model in ice blue on the mesh bracelet in a week or two, as it does wear differently and is worthy of its own spotlight. And for the photo shoot, why not take the watches down to the beautiful Manly Harbour and the Manly Boathouse? It is a great backdrop given the pedigree of the Longines HydroConquest. Initial Thoughts I’ll admit, I was not sold initially on it. Why? Well, let’s address the el...

Watches & Wonders: Tudor Introduces the Black Bay 54 Blue

Tudor continues to expand their Black Bay 54 collection at this year’s Watches & Wonders with the Black Bay 54 “Blue”. Since the launch of the original Black Bay 54, the diver has settled into a role as a favorite among enthusiasts for its slender, compact proportions. The original release was a straightforward black dialed, black bezel affair, and last summer saw the surprise launch of the “Lagoon Blue” reference that re-characterized the watch as a fun, more jewelry oriented diver than we would have expected. A diver with a blue dial and bezel is frankly something expected in a dive watch lineup these days, so this release is not so much a surprise, but it’s interesting to see how Tudor executes on a dive watch standard.  In terms of specs, there are no big surprises here, and this edition of the 54 follows those that have come before. The case in stainless steel measures 37mm in diameter and has water resistance to 200 meters. It runs on the same MT5400 movement, which is COSC-certified and has a silicon balance spring and 70-hour power reserve. It’s available on both a rivet style three link bracelet or a rubber strap.  The blue dial is very, very blue. Tudor refers to it as “sapphire blue” and in the bright lights of their booth at Palexpo the sunray finishing and almost purple-ish hues are quite prominent on the dial. It’s very saturated, and I think even in less intense lighting it will have a lot of presence. If you compare it to other blue wa...

The New Ming 37.11 Odyssey Adds a GMT Complication to their Popular Dive Watch Form Factor Worn & Wound
Ming 37.11 Odyssey Adds Nov 10, 2025

The New Ming 37.11 Odyssey Adds a GMT Complication to their Popular Dive Watch Form Factor

The latest from Ming is a continuation of their incredibly popular diver lineup, the current incarnation of which began with the 37.09 “Bluefin” and was later followed up with the 37.09 “Uni”. Both of those watches very effectively made use of a dual crown system (one for time setting, one for rotating an internal bezel that is not really a bezel at all), streamlined proportions, and Ming’s expertise in using sapphire and lume for both decorative and functional purposes. The new 37.11 Odyssey is an expansion of the ideas found in the Bluefin and Uni, with an added GMT feature and the option to spec the watch on the absolutely insane Polymesh bracelet. When we had our meeting with Ming earlier this year at Geneva Watch Days, this was the watch that brand founder Ming Thein was wearing on his wrist. I’ll be honest, the Polymesh bracelet kind of stole the show in that presentation, overshadowing the Odyssey just a little, but that’s simply because the Polymesh was a legitimately novel creation, while the Odyssey is something a little more familiar. That’s not a slight, of course. One of the things that makes Ming such an impressive brand is the way a clarity of design runs through each new watch they make, always in conversation with earlier pieces. That’s what helps you identify a watch as a Ming, but it can also mean that certain releases don’t create that vibrational spark of interest that really gets you excited.  That said, the Odyssey is an objectiv...
