Official certification as a Swiss Chronometer is a distinct mark of quality, lending considerable prestige to the most accurate of watches made in Switzerland. Certina and the official testing institute, COSC (Contrôle Officiel Suisse des Chronomètres), share a common drive for precision. It was more than sixty years ago now, in 1955, that a watch from Certina first received the coveted certification as a chronometer. In the 1960s the brand produced a series of certified chronometer models featuring the Calibre 25-651 self-winding (mechanical) movement. These watches enhanced the brand’s already strong reputation for reliable precision, and Certina became a byword for Swiss made quality.
The industry-wide transition to quartz in the 1970s and ‘80s brought the release in 1982 of Certina’s first COSC-certified model with a quartz movement. Recent years have seen the DS Master Quartz (2010) and DS-2 Quartz (2013) certified, and today around half of all quartz watches in the Certina collection are certified chronometers. Since the highly precise ETA PrecidriveTM has become the standard movement for the brand’s quartz watches and easily meets the COSC requirements, it is a simple matter for Certina to ensure they are certified as Swiss Chronometers.
