COSC is a unique organisation that plays a significant part in the validation of the precision and subsequent quality of chronometric Swiss watches.

The existing organisation of COSC was established in 1973, its head quarters are based in La Chaux-de-Fonds. The Swiss Official Chronometer Control (COSC) is a non-profit association, working for the Swiss watchmaking industry. It was created by five cantons Bern, Geneva, Neuch√Ętel, Solothurn, Vaud, along with the Federation of the Swiss Watch Industry (F. H.).

Prior to 1973 more labs existed but independently. They were brought together by the 5 cantons to create a unified independent bench mark that would service the Swiss industry.
