Watch certifications

All watch connoisseurs are concerned about certifications, as they should be. Certifications are a guarantee of quality and precision. They reflect the excellence, knowhow and passion of Swiss watch manufacturers. Would you like to know more about watch certifications? Here you go.

COSC certification

In 1973, five watchmaking cantons (Bern, Geneva, Neuchâtel, Soleure and Vaud) and the Federation of the Swiss Watch Industry decided to found the Official Swiss Chronometer Testing Institute, also known as the COSC. This independent control body grants certificates of excellence exclusively to Swiss watches.

To earn this certification, a watch undergoes performance-related testing. The average daily rate, the difference between rates in horizontal and vertical position, and the variation in rate depending on temperature are all fundamental criteria to earn this certification. Many major brands have their models regularly certified by the COSC, including Rolex, OMEGA, Tissot and TAG Heuer.

OMEGA METAS certification

In 2015, legendary watchmaker OMEGA unveiled its first Master Chronometer (METAS) certified watch, the OMEGA Globemaster Co-Axial Master Chronometer. This certification can be obtained by all Swiss watches, in addition to COSC certification. It ensures excellence in terms of performance and resistance to magnetic fields.

This certification, granted in addition to COSC certification, is open to all Swiss watches. It guarantees an unprecedented level of performance in terms of precision and resistance to magnetic fields.

A watch is rigorously tested to earn METAS certification. Indeed, it must withstand a magnetic field of up to 15,000 gauss. It must also have superior power reserve and water resistance. These tests take place over the course of 10 days. At the end of this time, if a watch passes the tests, it will receive METAS certification. Such certification is a way to dispel many concerns about the proper functioning of a timepiece.

There are still other certifications. If you would like to learn more, feel free to ask us for advice about certifications directly at our shop.
