COMPREHENSIVE INDEPENDENT CERTIFICATION AND HIGH STANDARDS

METAS Master Chronometer certification is comprehensive and covers the main functional characteristics of a watch including precision, resistance to magnetic fields, waterproofness and power reserve. Its standards are incredibly high, starting with precision. In order to qualify, a watch must be able to function within a 5-second range of variation each day (0 +5), that is to say 5 seconds less than the Official Swiss Chronometer Testing Institute (COSC) (-4 +6) carried out on a single movement and a second less than TUDOR's internal standard, which is applied to the brand's models with a Manufacture Calibre (-2 +4).

CRITERIA AND TESTS FOR METAS CERTIFICATION

All the tests and prerequisites leading to Master Chronometer certification, which the Black Bay Ceramic and the new Black Bay have achieved, are summarised below:

- Swiss Made
- Certification by the Official Swiss Chronometer Testing Institute (COSC)
- Precision at two temperatures, in six different positions and at two different levels of power reserve: 100% and 33%
- Smooth functioning when exposed to a magnetic field of 15,000 gauss and precision following exposure
- Waterproof to 200 m (660 ft)
- 70-hour power reserve
