A dive-oriented design built around a 40mm case in 316L stainless steel, 11.2mm thick, with a uni-directional rotating aluminium bezel. The black dial carries Super-LumiNova on both hands and indices, while a single anti-reflective sapphire crystal sits above. A screw-down crown and screwed case back contribute to the 300-metre water resistance rating. The solid-link stainless steel bracelet fastens with a deployment clasp featuring push buttons and a safety extension, lending the watch a secure, considered fit on the wrist.

Learn more about Certina

Adolf Kurth founded a watchmaking business in Grenchen in 1888 with his brother, and the family produced movements and complete watches under several names before settling on Certina — from the Latin certus, meaning sure — in 1938.

The house built its identity on shock protection at a time when a dropped watch usually meant a repair bill. The DS system, introduced in 1959, stood for Double Security: a reinforced case, a strengthened crystal, a screwed caseback with an O-ring seal, and a shock-absorbing mount for the movement. The turtle emblem that marks DS watches became the brand's signature.

The system was tested in public and in earnest. Certina DS watches accompanied the Swiss Dhaulagiri expedition to the Himalayas in 1960 and were worn on subsequent scientific and diving expeditions, including deep-sea work off the Mediterranean coast.

The company was among the founders of the General Watch Co consortium in 1971, which later folded into ASUAG and then the Swatch Group, where Certina sits today.

Its modern position is value-focused Swiss mechanical watchmaking: the DS Action and DS PH200M dive watches, the DS-1 and DS-2 dress and sport lines, and widespread use of the Powermatic 80 movement with its eighty-hour reserve. Certina has timed motorsport and cycling events, including a long association with the Dakar Rally.

Frequently asked questions, and things you should know about this watch

Can I swim with it?

Yes. At 300m it is rated for swimming, snorkelling and recreational diving.

Water resistance explained

Will the glass scratch?

Unlikely. Sapphire is second only to diamond in hardness and shrugs off everyday marking.

Sapphire, mineral and acrylic compared

Does it need a battery?

Yes. It is quartz, so expect a battery change every two to three years at a jeweller.

Quartz, automatic and solar compared

What size strap does it take?

20mm. Any strap of that width will fit, and on most modern watches quick-release bars make the swap a two-minute job with no tools.
