What is a Chronometer Watch? A Guide to Ultra-Precise Watches

When a watch touts on its dial that it is a "Chronometer" or an "Officially Certified Chronometer" or even a "Superlative Chronometer," what exactly does that mean? How does a chronometer watch differ from a watch that does not make that claim? For that matter, a newbie to the timepiece game might ask, what is the difference between a watch with "chronometer" on the dial and a watch with "chronograph" on the dial? In this comprehensive guide, we attempt to answer all of your burning questions about chronometer watches and what sets them apart. [toc-section heading="The Chronometer Throughout History"] Our original, classical definition of a chronometer can be traced back to the golden age of seafaring exploration in the 18th Century, when ships required the use of a highly accurate onboard clock that enabled their navigators to determine longitude in order to avoid the perils of running aground or veering hopelessly off course. The man credited with developing the first of these “marine chronometers” was legendary British watchmaker John Harrison; his invention facilitated the celestial navigation used at the time by navigators at sea to determine their ship’s position in coordination with a sextant. Marine chronometers, which were essentially highly accurate clocks mounted on gimbals inside wooden boxes, were among the first portable timepieces and were instrumental in the global seagoing trade that helped build our modern, interconnected world.

The Next Generation of the Omega Seamaster Planet Ocean is Here Worn & Wound
Omega Seamaster Planet Ocean Nov 19, 2025

The Next Generation of the Omega Seamaster Planet Ocean is Here

You have to give credit where it’s due: Omega teased a big update to their Seamaster Planet Ocean, and they delivered. The collector community will surely debate every aspect of the new fourth generation Planet Ocean, but this is not an iterative change or a minor tweak. It’s a fairly radical rethinking of the style and aesthetic of Omega’s premier professional diving watch, and when you put an early version of the Planet Ocean next to the new gen, it’s honestly hard to see the connection between them. Not impossible, but by “iconic dive watch” standards, which keeps stalwarts like the Submariner and Fifty Fathoms looking much like the watches that they started life as, this is a different kettle of fish entirely.  We’ll start with the case, because that’s really where the heart of the Planet Ocean’s rethinking really comes into play most clearly. The knock on the Planet Ocean, since its inception, has always been that it’s overly thick. Of course, being that this is a pro diver with double the water resistance of most other consumer oriented divers, a little heft is to be expected. Still, the general proportions of previous Planet Ocean cases were always a cause of consternation among a subset of die hards.  The new watch measures 42mm in diameter and is 13.79mm thick, a significant reduction over the previous Planet Ocean’s 16.1mm case height. The new case also benefits from a flat sapphire crystal and a new titanium caseback, both of which ought ...

TAG Heuer’s Latest Monaco is an Impressive Achievement in Additive Manufacturing

Dubai Watch Week is upon us, and TAG Heuer is using it as a launching pad for for a new version of what is objectively one of the most impressive watches they’ve ever made. The Monaco Split-Seconds Chronograph Air 1 builds on the Monaco Split-Seconds that was introduced at Watches & Wonders in 2024. That one, you’ll recall, had a movement fashioned largely from titanium and weighed in at just 85 grams. The retail price at the time was a head scratching CHF 135,000, but it was also an incredibly impressive caliber and feat of engineering. Rattrapante chronographs like this are indeed quite rare, and certainly one with a caliber made of titanium is unheard of and adds additional layers of complexity to whole endeavor.  The new Air 1 version of the watch is still 85 grams, but it achieves that weight even with new solid gold components in the case. The design of the case, still in the iconic Monaco square, has been substantially reworked and inspired by design and manufacturing processes that are part of the Formula 1 landscape. The case has effectively been hollowed out, with intricately skeletonized case flanks designed to maximize the weight to performance ratio. TAG Heuer achieves this through a process they refer to as Selective Laser Melting (SLM). This is an additive manufacturing process that is typically applied in aerospace, medical, and automotive manufacturing, and like other forms of 3-D printing it’s essentially a cheat code in achieving otherwise impossi...

Hands On: A. Lange & Söhne’s Saxonia Thin Onyx is German Formal SJX Watches

Hands On: A. Lange & Söhne’s Saxonia Thin Onyx is German Formal

One of the last launches of 2025 for A. Lange & Söhne, the Saxonia Thin Onyx is a riff on the brand’s most affordable and simplest watch. It’s only modestly different from the standard model – the dial is onyx stone while the case metal isn’t part of regular production – but the Saxonia Thin Onyx stands out. The watch is almost the dictionary definition of a formal-wear timepiece: flat, two hands and minimal colour or embellishment, so much so it blends into conventional Western formal dress. In fact, this is one of the strongest offerings in the formal-dress-watch segment because it is stark, elegant, and priced well. Initial thoughts Lange tend towards the high end of the price spectrum simply because of the brand’s focus on complications and quality. And the brand has also raised retail prices significantly in the last few years. So an affordable-ish Lange that isn’t a run-of-the-mill watch is a good thing. The Saxonia Thin Onyx is exactly that. While it is based on Lange’s entry-level dress watch, a fine but no frills timepiece, the onyx edition is different in look, feel, and materials. It’s available in two metals not offered for the regular production – platinum and Honeygold – and the dial is of course onyx, a mineral stone used sparingly (so far) in limited editions. At 6.2 mm high, the case is half the thickness of a Datograph and sits flat against the wrist. Though the case is 40 mm rather than the smaller size offered for the standard mod...

When A Watch Brand’s “Entry Point” Is The Best Option

There’s a small, stubborn truth that keeps resurfacing whenever you walk into a boutique, scroll pre-owned listings, or stare at your wrist: the best daily watch is often the one that sits at a brand’s “entry point.” Big Swiss maisons spend years distilling their DNA into a watch that captures the soul of the brand […] Visit When A Watch Brand’s “Entry Point” Is The Best Option to read the full article.

What Is A Fluted Bezel On A Watch? Teddy Baldassarre

What Is A Fluted Bezel On A Watch?

If you’re new to the watch-collecting hobby, you’ve undoubtedly seen or heard references to watches with fluted bezels, but what does that description actually mean? Are fluted bezels a feature of sports watches or dress watches, of watches for men or for ladies? Are they designed for practical use or purely as an aesthetic touch? As is common in the world of watches, the answers to all of these questions are not as simple as you might think.  Before getting into the fluted type in particular, let’s get really basic and review what a watch’s bezel is and what it’s for. As we explore in more detail here, a bezel is the front part of a watch’s 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. They can also be thin or wide; stationary or built to rotate in either one direction or both; purely decorative (i.e., set with diamonds) or utilitarian in nature (i.e., inscribed with a scale for some type of calculation). Fluting is defined as “a groove or set of grooves forming a surface decoration,” so a fluted bezel is one that features this type of grooved or ribbed texture on its top surface. Initially, as with most every element of a watch, a fluted bezel design was designed with a practical purpose in mind: the grooved surface made it easier for a watchmaker to screw the bezel tightly into the case to...

The Yema Navygraf is the Latest Diver to get the Mother of Pearl Treatment Worn & Wound

The Yema Navygraf is the Latest Diver to get the Mother of Pearl Treatment

There is something about mother-of-pearl that seems to be catching watchmakers’ eyes lately. While I highly doubt it has to do with the fact that “Mother of Pearl” is a phenomenal drag name, I can’t totally rule that out as a possibility. Instead, more likely, it has to do with the ease in which adding the iridescent substance onto an existing design gives it new personality without really reinventing the wheel. Case in point: Yema’s Navygraf Pearl. Undoubtedly, the Navygraf is a handsome watch. But, like a drag queen, sometimes it’s hard to describe something as both “handsome” and “pretty” simultaneously. At least, that was my first impression of this French-made watch. Using the classic dive watch model, like the Navygraf, and inlaying mother-of-pearl seemed, in a way, incongruous to the steely, masculine athleticism of the silhouette. But, upon examining the bezel and dial a little more closely, I’m more inclined to think this is less of a gimmick and more of a thematic appreciation for the beauty and sport that the ocean provides (unfortunately, I’m only speculating – the press release was more focused on the technical specs of this Navygraf). So, what are the specs? This is a thinner Navygraf variant, equipped with a micro-rotor caliber CMM.2, meaning that the 316L stainless steel case measuring 39mm, only clocks in at 9.75mm thickness. The CMM.2 caliber also promises around 70 hours of power reserve, making it suitable for any diving trips ...
