The Swiss Official Chronometer Control (Controle Officiel Suisse des Chronometeres, or COSC, in French). COSC is an independent association governed by the Swiss Civil Code.
Watch companies desiring the chronometer designation on their best pieces send movements to COSC. (COSC tests uncased movements; the companies case the movements after the tests.) COSC issues a performance certificate for each timepiece which successfully passes the tests.breitling watch
There are three COSC centers in Switzerland where watch companies send movements to be tested--in Geneva, Bienne and Le Locle.
Switzerland has been officially testing chronometers since 1878. COSC as it exists today was founded in 1973.
