The Double Security (Part 2)
Certina’s international reputation as a sports brand has been founded on the DS Concept since 1959. This system makes the watches extraordinarily robust. The secret of this Double Security (DS) system lies in the elaborate security features. The highly robust construction applies to all parts of the watch: scratch-resistant sapphire crystal, a complicated system of seals including seals on the setting stem and crown, and a reinforced case back. 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 – sporty, casual or elegant, ladies’ or men’s. This philosophy of utmost reliability is reflected in the symbol of the turtle shell, Certina’s brand logo which can be found on each timepiece.
