Certina kept pace with the times as well then as it does today - with its innovations, famous friends and involvement in some truly spectacular events and adventures. Certina’s international reputation as a sports brand has been founded on the DS Concept since 1959. This system makes the watches extraordinarily robust. There is a good reason why all the Certina collections bear the abbreviation DS in their name. Today the Double Security Concept is integral to all Certina models.
