Swiss Federal Institute of Metrology
It is an independent organization responsible for testing and certifying the accuracy, precision and quality of mechanical watches. This organization cooperates with watch manufacturers to conduct rigorous testing on watches to ensure they meet the Master Chronograph standards. Watches with the Master Chronograph certificate have been subjected to a series of tests, including an accuracy test by the Swiss Institute (COSC), followed by eight additional tests by METAS, the Swiss Federal Institute of Metrology. These tests evaluate various aspects such as accuracy Timekeeping, resistance to magnetic fields, water resistance and durability. The certification denotes exceptional performance and quality, and watches that pass these tests receive a 5-year warranty.
