Water resistant to a pressure of 30 bar
The water resistance of a watch indicates the maximum depth and pressure at which it continues to function. This Certina model has been tested to an amazing 30 bar (300 m). This is significantly more than in similar watches, many of which are water resistant to less than 10 bar (100 m) - a hurdle that all Certina timepieces easily overcome, thanks to the DS Concept.
Exact, more exact - chronometer. A chronometer is a watch whose precision has been officially tested and certified by an independent testing laboratory. This Certina model has been tested by the Contrôle officiel suisse des chronomètres (COSC), the official Swiss testing authority, and awarded the quality certificate.
