Master
Chronometer

Behind the elegance of every Master Chronometer timepiece is the highest level of testing: 8 tests over 10 days, to ensure superior precision and magnetic resistance. We’ve raised our standards. You can too.

Raising
standards

Inside this timepiece are the revolutionary components that guarantee the highest standards of performance. From the Co-Axial escapement for long-lasting precision, to the silicon balance spring for superior anti-magnetism, OMEGA has conquered every challenge that matters.

Discover the 8 tests

To achieve the Master Chronometer title, all movements and completed watches must face 8 stringent tests, which have been set by the Swiss Federal Institute of Metrology (METAS). As shown below, these examinations guarantee the highest standard of precision, performance, and magnetic resistance in the Swiss watch industry. Only perfectly functioning timepieces that pass every test will earn the certification.

  1. Function of movement during magnetic exposure

  2. Function of complete watch during magnetic exposure

  3. Chronometric performance: magnetised and demagnetised

  4. Chronometric precision day-to-day

  5. Deviation of chronometric precision in six positions

  6. Isochronism

  7. Power reserve testing

  8. Water resistance

Double certification

For OMEGA, the COSC “chronometer” certification is just the beginning. With 8 additional Master Chronometer tests, we go beyond the industry standard. You can view the Master Chronometer results of your watch by entering its certificate number online.

Master Chronometer Watches

When OMEGA introduced its METAS-approved testing in 2015, the Globemaster was the first watch to emerge. Since then, the brand has subjected more and more of its mechanical timepieces to the stringent 10-day process.
