A Closer Look At COSC’s New Excellence Chronometer Certification

Contrôle Officiel Suisse des Chronomètres (COSC) is the largest Swiss independent testing facility for watch movements. Founded in 1973, this non-profit foundation aims to guarantee the precision of Swiss watches through a neutral, independent, and rigorous method. Watches with movements that passed the tests can be called “COSC-certified chronometers,” accurate to within -4/+6 seconds per […] Visit A Closer Look At COSC’s New Excellence Chronometer Certification to read the full article.

COSC Upgrades Standards to Certify More Than Timekeeping

Interesting news just out of Contrôle Officiel Suisse des Chronomètres (COSC), the venerable Swiss chronometer testing body, which has just announced a major revamp to its testing to honour the COSC’s standard’s 50th anniversary. Excellence Chronometer, COSC’s new and improved certification program, goes beyond the ISO 3159 norm that has defined its tests for decades. Instead of just testing movements, Excellence Chronometer will require completed, cased watches to run within -2/+4 seconds a day, as well as pass wear simulation and magnetism tests. Initial thoughts While COSC remains the primary chronometer testing body in Switzerland, thanks largely to Rolex, its protocols have been due for an update for some time now. With the rise of alternative and in-house precision testing programs, the standard chronometer certification can sometimes feel left behind. Rolex’s own Superlative Chronometer certification first requires a COSC certificate, but then makes sure the watches run at -2/+2 seconds per day after further in-house testing. The METAS Chronometer program also requires the standard COSC certificate, but guarantees a regulation of 0/+5 seconds per day and a great resistance to magnetic fields. Seeing that COSC slowly updates and imposes more stringent criteria is a good sign, but it may still not be good enough. With the rise of advanced internal certification programs, it looks like some brands submit their models to COSC testing just to make sure they can...

The COSC Introduces the New Excellence Chronometer Certification

The Contrôle Officiel Suisse des Chronomètres (COSC, the body responsible for certifying watch movements as Swiss chronometers) has just announced a new chronometry standard that will be rolled out over the course of 2026. The news comes at a time when the COSC has some competition for timekeeping certifications, most notably the METAS certification (which first requires a watch movement to be COSC certified) used by Omega and Tudor, as well as other certifications provided by the brands themselves.  The new COSC certification is being framed as an additional level of certification that will accompany the familiar “Certified Chronometer” tag that is seen on the dials and paperwork of millions (literally) of watches that have been put through the COSC paces over the years. The new “Excellence Chronomenter” certification provides an additional layer of guarantee of reliability that goes beyond simple accuracy. As a refresher, COSC certification certifies the movement is working at an optimal level, not a fully cased watch. To achieve a Certified Chronometer certification, a movement must show average accuracy of -4 to +6 seconds per day over a 15 day period, tested across 5 positions and 3 temperatures.  The Excellence Chronometer certification tightens the accuracy threshold from a spread of 10 seconds in total to 6 (-2 to +4 seconds per day). It also adds metrics for magnetic resistance and power reserve verification in fully cased watches. According to the COS...

In-Depth – L’Atelier Bernard, the Extraordinary Story of Two Young Belgian Watchmakers in Fleurier and their “Owl” Watch

Hitting the road to Fleurier, the discovery of L’Atelier Bernard was not what I expected. Bernard is a rather dated first name – one you rarely hear anymore for young people in Europe’s French-speaking countries. So, when I pushed open the door of their workshop in Fleurier, I was expecting to meet two old Swiss […]

Hugues’ Accomplishment: The Story of Hugues Bürki

Nestled in the Jura Mountains, La Chaux-de-Fonds has been a cradle of Swiss watchmaking ever since its watchmaking school, the Technicum, opened in 1865. For aspiring watchmakers, the climax of their training was traditionally the creation of a montre école – or what’s known as a school watch. This is the story of Hugues Bürki, a Technicum alumnus, who built what would become a record-breaking school watch, and who would later make horological history as a movement engineer. Hugues Bürki. Image – author The Technicum The watchmaking school of La Chaux-de-Fonds was founded in 1865. In its early days, the school occupied rooms inside the modestly named ‘Technicum’, a local vocational-technical school. By 1885, the school’s own building had been inaugurated, yet the name Technicum stuck. In 1933, in the wake of the global economic crisis, the nearby watchmaking schools in La Chaux-de-Fonds and Le Locle were merged to form the Technicum Neuchâtelois. The Technicum in the 1960s. Image – author It demands attention that both divisions of the Technicum Neuchâtelois had a particularly strong focus on high-precision chronometry at the time compared to other watchmaking schools in Switzerland, which specialised in other domains, such as the construction of complications and traditional finishing techniques. In fact, some of the innovations in chronometry we associate with brands like Longines can actually trace their roots to the Technicum Neuchâtelois, including...

Hands On: Audemars Piguet Neo Frame Jumping Hour

Having celebrated its 150th anniversary in 2025, Audemars Piguet (AP) has kicked off 2026 with a slate of new models, including one of the most complicated watches in its history. But it was a simpler watch that that generated the most buzz at the glamorous launch event in the Swiss alps: the Neo Frame Jumping Hour, which is both a new watch and the beginning of a new collection that replaces the [Re]master series. The Neo Frame is a regular production wristwatch in 18k rose gold inspired by the Pre-model 1271, a historical AP reference from 1929. Though rooted in the Art Deco era, the Neo Frame is an eminently modern watch with a novel case and dial construction and the brand’s latest-generation automatic movement. Initial thoughts The name Audemars Piguet is nearly synonymous with that of its signature product, the Royal Oak. While many brands would probably trade their entire catalogues to have a single hit like the Royal Oak, AP has sought to diversify its product line up with the introduction of collections like the Code 11.59 and the short-lived [Re]master series. Despite these efforts, the Royal Oak family remains AP’s commercial engine, making the introduction of a new collection, anchored by a rectangular jumping hours watch, especially notable. The jumping hours complication seems to be enjoying renewed interest among collectors, which makes release of the Neo Frame feel timely. But up close and on the wrist, it doesn’t look or feel like anything else on t...

Breitling Launches First Titanium Navitimer in New Aston Martin Collab

Breitling announced today that it has become the Official Watch Partner of  British luxury carmaker Aston Martin and the Aston Martin Aramco Formula One racing team. The multi-year global partnership, which marks the Swiss watchmaker’s return to the high-octane world of F1 motorsports after many decades, kicks off with a wristwatch milestone: the Breitling Navitimer B01 Chronograph 43 Aston Martin Aramco Formula One Team, which is no less than the first timepiece in the iconic Navitimer series with a case made of lightweight titanium.  The two world-renowned companies have some ties throughout their prestigious histories. Breitling, while it has not been as visible in the racing world over the years as brands like Rolex and TAG Heuer, was an early contributor to motorsport timing. In 1907, Léon Breitling, who had founded his eponymous watchmaking firm in 1884, invented a device called the “Vitesse” (French for “speed”), a mechanical chronograph capable of measuring speeds up to 250 miles per hour. Its utility and precision spurred the Swiss police to adopt it for speed enforcement, which led to the world’s first speeding tickets. Just six years later, in 1913, Lionel Martin and Robert Bamford drove their hand-built automobile to a defining victory up the treacherous Aston Hill, giving their company a name and kicking off a long tradition of making cars built for both performance and luxury. The paths of the Swiss high-horology house and the British marque cr...

Affordable Vintage: the Longines Grand Prize

Longines is a storied and well-respected Swiss watch manufacture that formed in 1832 and has continued uninterrupted to this day. From the first wrist chronometer in 1911, to groundbreaking flyback chronographs in the 1930s, to the world’s first hi-beat wrist chronometer in 1959, Longines holds their own in the watchmaking world.  My favorite period for watches is the 1950s through the 1970s and Longines was one of the top accessible brands during that time. In 1954 Longines began a marketing strategy of product families, launching the Conquest line of watches. In 1957 they introduced the Flagship line, adding to what would become a large group of watch families, many of which are still made today. Other lines that came later include the Admiral, the Ultra-Chron and the Grand Prize. The Grand Prize line was named in honor of the multitude of watchmaking awards and honors that Longines had accumulated over the decades. It was a relatively short-lived family, produced from about 1958 to 1964 according to my research. I have found that the majority of Longines watches produced during these decades were all fairly equal in quality and craftsmanship, with most of the differences in the families being design related. The Conquests were rugged and sporty, on par with the early non-diver Omega Seamaster watches. The Flagship series were dress watches, while the Admiral line was a mixture of both. The Grand Prize family were pretty much all thin, elegant everyday type dressier w...

The 9 Most Accurate Watches for the Precision-Obsessed

Fundamentally, mechanical and quartz movements do the same thing: they both tell thetime. But the ways in which they both do it couldn’t be more different. Not to get into acomparison guide here, but in a nutshell: a mechanical watch is powered by a mainspringthat’s either wound by hand or automatically through wrist movement. Energy is releasedthrough a complex system of gears, an escapement, and a balance wheel that beats steadily back and forth. There’s no battery, just centuries-old engineering refined to an art form. These watches aren’t the most accurate, but accuracy isn’t really the point. Craftsmanship, tradition, and the emotional connection are. Quartz watches, on the other hand, are powered by a battery and use an electrical current to make a quartz crystal vibrate at 32,768 times per second. That vibration is incredibly stable, which is why quartz watches are vastly more accurate and require far less maintenance. They’re practical, reliable, and often more durable for everyday use, as well as being notably more affordable. Neither system is inherently “better,” though. Mechanical watches speak to passion and heritage, while quartz prioritizes precision and convenience. Ultimately, it’s less about the movement inside and more about what you want your watch to represent on your wrist. [toc-section heading="Next-Level Accuracy"] Some watches measure accuracy in seconds per day, others by seconds per month. Butthere also exists a small group of t...

He might not have been a watchmaker by training, but Raymond Weil (1926–2014) did start an eponymous watch brand. Remarkably, he did so at the age of 50 in 1976. The timing is defiant.

Industry News: Sellita Introduces the SW200-2 with 65 Hour Power Reserve

There’s a “don’t change it if it ain’t broke” mentality in Swiss watchmaking. Progress is slow, and it often seems that there’s a general distrust of change. An example of this is in the mechanical movements that power most of our watches. Chances are, you have at least one watch with an ETA 2824 or a movement based on the 2824 in your collection. If you’re like me, you have several. For Swiss-made watches of a certain price point, they are the standard. They are “workhorses” that, while not the most feature-rich, offer reliability and serviceability. And part of the reason for that is that the design has been around, largely unchanged, since the 1970s (the 2824-2, which is the current standard, was released in the 80s). That is, until 2013, when ETA launched 80-hour movements based on the 2824-2. First debuted in a Tissot as the Powermatic 80, ETA nearly doubled the 2824’s power reserve by slowing the escapement’s frequency from 28,800bph to 21,600bph, introducing synthetic components, and increasing the mainspring’s capacity. The biggest update to the 2824 format in a generation (though they no longer use that numbering), as ETA is part of Swatch, these movements gave the group’s catalog of brands under Omega an unexpected edge in the market, but were not available to third-party brands, thus limiting their overall impact. The ETA 2824 featured in a Sinn 556i In 2003, Sellita began supplying movements to third parties as a response to Swatch’s...
