In 1959, Certina launched its DS "Double Security" concept, a revolutionary system that integrated a shock-resistant assembly, reinforced case and sapphire crystal, along with hermetic seals on the stem, crown and reinforced case back. With a Swiss team, the first DS-equipped Certina travelled to the top of Mount Dhaulagiri (Himalayas) in 1960, and successfully demonstrated the extreme resistance of the timepiece under the toughest conditions.
The new DS1 Automatic extends this early tradition of resistance and durability.
The case, in stainless steel, measures 39mm. It has an AR-coated sapphire crystal, a display back, and is water resistant to 100 meters.
Movement is the Swiss automatic ETA caliber 2824-2 with 25 jewels, 28,800 vph and a power reserve of 40 hours.
