COSC validation is a symbol of superior craftsmanship and reliability in chronometry.

The central system of a mechanical watch involves the mainspring, which supplies energy as it loosens. This system, however, can be susceptible to external factors that may impact its accuracy. COSC-validated movements undergo strict testing—over 15 days in various conditions (5 positions, 3 temperatures)—to ensure their resilience and reliability. The tests measure:Mean daily rate accuracy between -4 and +6 secs.

For timepiece enthusiasts and collectors, a COSC-validated timepiece isn’t just a item of tech but a testament to enduring quality and accuracy. It represents a timepiece that:Presents outstanding reliability and accuracy.

Longines, for instance, offers collections like the Archive and Soul, which feature COSC-certified mechanisms equipped with advanced materials like silicon equilibrium springs to boost resilience and efficiency.Historical Context and the Development of Timepieces

Since the formal establishment of Controle Officiel Suisse des Chronometres in 1973, the certification has become a benchmark for evaluating the precision of luxury watches, sustaining a tradition of excellence in horology.Conclusion
