COSC
A chronometer is a high-precision watch capable of displaying the seconds and
housing a movement that has been tested over several days, in different positions
and at different temperatures, by an official neutral body, the “Contrôle Officiel
Suisse des Chronomètres” (COSC). Movements which meet precision criteria,
established under ISO 3159, are granted an official chronometer certificate.
