While that may be true, some of today’s most prestigious watch brands still want to highlight the quality of their watches’ mechanical excellence and fine workmanship with their very own certificates the Patek Philippe Seal, introduced in 2009, is a great example.Īlthough that brand’s highly sought-after timepieces have been stamped with the most elite and oldest quality hallmark in haute horlogerie, the Geneva Seal, which is exclusively for timepieces produced within the canton of Geneva, Patek Philippe apparently felt a need to differentiate itself by creating a new seal that goes even beyond those strict requirements. With many quality seals and chronometry certificates in existence, one might think that in modern times there is no need for yet another testing method or hallmark.

In order to qualify for the Chronofiable test, the watch movement has to have first earned a C.O.S.C. The tests are conducted in accordance with the DIN 8319 standard under the auspices of the state offices for weights and measurements of Thuringia (LMET) and Saxony (SLME).Īpart from the chronometer-testing institutes, there are a handful of other facilities including Chronofiable (which forms part of the Qualité Fleurier) its main job is to test the reliability of serially produced watches in strict and rigorous procedures such as shock and water resistance and forces exerted on components like the winding stem or pushers. Initiated by German jeweler and watch manufacturer Wempe, here the entire encased watch (not only the movement as with the C.O.S.C.) is tested in the state-of-the-art laboratories installed the ancient Glashütte observatory. There is another chronometer-testing facility based in Glashütte, Germany. Interestingly, the millions of chronometer certificates issued each year account for only three percent of Switzerland’s annual watch production. Rolex is by far the institute’s biggest customer, submitting the largest numbers of mechanical movements for certification, followed by Omega, Breitling, TAG Heuer, and Panerai.

(Contrôle Officiel Suisse des Chronomètres), headquartered in La Chaux-de-Fonds.īased on the ISO 3159 norm, this testing facility has certified billions of Swiss watch movements since its inception in 1973. The most important and famous one today is Switzerland’s C.O.S.C. In the nineteenth, twentieth, and twenty-first centuries, expert institutions were founded to test and certify the quality of the wristwatch’s precision. For thousands of years, watchmakers and scientists have striven to improve the accuracy of mechanical devices, from the first sundials and giant clocks in medieval churches to the marine chronometers crucial for navigation in the seventeenth and eighteenth centuries and wristwatches that once served as medical and scientific tools. Precision and chronometry have been the holy grails of horology since its beginning.
