Burgess Clock B, The World’s Most Precise Pendulum Clock, Is Made To A 250-Year-Old Design By John Harrison, Longitude Prize Winner And Inventor Of The Marine Chronometer - Reprise

Two-hundred fifty years ago, Longitude Prize-winning clockmaker John Harrison made clocks losing just one second per month. But that wasn't enough for him: in his later life, Harrison claimed that he could make a wall clock with a then-unheard-of-precision of just one second over 100 days! And 250 years later, it turns out he was right.

COSC Upgrades Standards to Certify More Than Timekeeping SJX Watches

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...

Behind the DIN 8330 Standard for Pilot’s Watches

Standards and certifications in watchmaking were primarily developed for chronometry, as well as to reassure the buyer that their watch had been thoroughly tested to a certain level of accuracy. The standards we see most often in the technical specifications are COSC, METAS, and other company or regional chronometry certifications. In modern watchmaking, other key standards like the ISO 6425 dive watch standard, which was developed in the 1990s and followed by watch companies, also come into play. These standards were largely based on various military set standards for watches; however, since each military set their own requirements, there was not one universally followed standard. The International Organization for Standardization (ISO) published specific requirements and testing procedures for a watch to be officially designated a “Diver’s watch”. While there is no ISO standard for pilot’s watches, there are specific requirements set by militaries around the world. One of the most well-known standards is from the WWII German pilot’s watch known as the “Beobachtungsuhren” or “B-Uhren.” B-Uhren pilot’s watch standards are well documented and are still followed by many watch companies to this day. In March 2012, Sinn lead an initiative in collaboration with the Faculty of Aerospace Technology at the Aachen University of Applied Sciences to create TESTAF – Technical Standard for Pilot Watches. TESTAF was developed so that a pilot’s watch meets all mod...

The Top 5 Dive Watches for Beginners Under $1,000

Dive watches possess a sort of primordial appeal. Dating back to the 1950s, they were invaluable tools for early divers to monitor their dive time. But what makes a dive watch a dive watch? It varies depending on who you ask, but the International Organization for Standards (ISO) 6425 standard provides a perfect starting point. Per ISO, a dive watch must: a) be water-resistant to at least 100, b) possess a method of tracking dive time, c) must show that time in resolution of no larger than minutes over the span of an hour, plus a litany of other tests to achieve ISO 6425 certification. In today’s Chronicle, we’re doing a deep dive into our picks for the five best dive watches for a new enthusiast. Dive watches possess a sort of primordial appeal.

Pros: Graduated shades of intense blues on the dialA real joy to see the redesigned calibre 899 on the case back ISO 6425 complaint proper ‘diving’ watch  Cons: Some may not be fans of the screw-in internal Bezel 42mm case size will wear large on wrists smaller than 6.5 inchesSome may find it pricey  Overall Rating: 8.1/10 Value for money – 7.5/10Wearability – 8/10Design – 8.5/10Build Quality – 8.5/10  Reference : 9068180 Late last year in October 2020, Jaeger-LeCoultre introduced the Polaris Mariner for their Polaris collection.

With the latest Polaris Mariner Date model, the alarm and sound transmission mechanisms have been left out for the Memovox model, with the Mariner Date being the simple yet classic diving...
