 Creation of the COSC
 
Founded in 1973 in its current structure, the COSC is a not-for-profit association. It was created by five watchmaking cantons (Bern, Geneva, Neuchâtel, Solothurn and Vaud) as well as the Federation of the Swiss Watch Industry. It encompasses the laboratories that had been established independently of each other from the late 19th century onwards.
