Omega Master Chronometer – the new Swiss official certification for horological excellence.

Last year in December Omega held a press conference in Geneva together with the Swiss Federal Institute of Metrology (METAS) to announce a new watch certification process that will now become active in the year 2015. The Omega Globemaster Master Chronometer and the Omega Ploprof Master Chronometer are the first watch to be tested and approved according to this new process, which, in addition to measuring the performance of the watch in daily wearing conditions, ensures that it functions properly when exposed to even very strong magnetic fields of 15,000 gauss. This is not an Omega only test, any other watch brand can submit its watches for these METAS-approved tests in order to receive Master Chronometer standing, a label that at once makes a statement about the quality of not only the mechanical movement but also of the watch itself.

These eight criteria are measured during the METAS certification process:

The function of the movement during exposure to a magnetic field of 15,000 gauss
The deviation of the running time of the watch in six positions
The deviation of the running time of the watch between 0 and 2/3 power reserve
The function of the watch during exposure to a magnetic field of 15,000 gauss
The deviation of the average daily precision of the watch after exposure to a magnetic field of 15,000 gauss
The average daily precision of the watch in tests replicating daily wearing conditions (six positions, two temperatures)
The power reserve of the watch (autonomy – functioning without winding)
The water resistance of the watch (tested in water)

So before the Omega-watch (or any other) is exposed to the magnetic field and its performance is measured according to the criteria approved by METAS, the movement must pass the tests established by the Contrôle Officiel Suisse des Chronomètres (COSC).

Along with their watch, customers will receive a certification card that includes an identification number, which they can use to see how their watches performed on each test. This documentation is proof that the watch has been certified by METAS.

The Omega Globemaster, and all the others following, will have to perform within a tolerance of 0 and + 5 seconds per day during and after exposure to a magnetic field measuring 15,000 gauss in order to receive its Master Chronometer designation.

Everything is transparent! You will be able to see the testing at Omega and you will have access to all the data concerning your watch through a new data base.
