Introducing the Omega Globemaster Co-Axial Master Chronometer

The Globemaster is the world's first certified Master Chronometer. The timepiece represents Omega's most advanced mechanical movement combined with a design inspired by early Constellation models with their fluted bezel and distinctive pie-pan dial.

In December of 2014, OMEGA held a press conference together with the Swiss Federal Institute of Metrology (METAS) to announce a new watch certification process that will become active in 2015. The Globemaster is 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 strong magnetic fields of 15,000 gauss. Any watch brand can submit its watches for these METAS-approved tests in order to receive Master Chronometer standing.

The eight criteria that are measured during the certification process are:

1 The function of the movement during exposure to a magnetic field of 15,000 gauss

2 The deviation of the running time of the watch in six positions

3 The deviation of the running time of the watch between 0 and 2/3 power reserve

4 The function of the watch during exposure to a magnetic field of 15,000 gauss

5 The deviation of the average daily precision of the watch after exposure to a magnetic field of 15,000 gauss

6 The average daily precision of the watch in tests replicating daily wearing conditions (six positions, two temperatures)

7 The power reserve of the watch (autonomy functioning without winding)

8 The water resistance of the watch (tested in water)

The Omega Co-Axial Master Chronometer calibre 8900/8901 is a METAS-certified, 39-jewel bidirectional self-winding movement with silicon balance spring (Si14) that beats at 25'200 A/h (3.5 Hz), and anti-magnetic >15'000 Gauss.
