COSC

Tissot markets COSC-certified watches, which means they are approved stopwatches. This certificate is issued by the COSC (Official Swiss Chronometer Testing Institute), which spends 15 days conducting a battery of extremely stringent tests on the movements to check their accuracy, anti-magnetism and resistance to impact.
