Stepping up in the same colour and case shape
The DS-7 line draws its shape from a Certina model of the 1970s, and the integrated bracelet makes that lineage immediately legible — the case and links flow into one another without a break, the way sport watches were built before the lug-and-strap became the default. At 39mm it fits a wide range of wrists without the retro proportions feeling oversized, and at under 10mm thick it sits closer to the wrist than most integrated-bracelet designs manage. The sunray blue dial shifts between grey and vivid depending on the angle of light, and the baton indices keep the face clean enough that the colour does the work. The butterfly clasp adjusts without tools, which matters on a bracelet this substantial — at 121g it is present on the wrist in a way lighter integrated designs are not, and the fit makes the difference between that feeling purposeful or merely heavy. The end-of-life battery indicator is the kind of detail that earns its place quietly: no sudden stoppage, just a change in the seconds beat to signal the battery needs attention before the watch stops keeping time.

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 100m it is rated for swimming and snorkelling, though not for diving.
Water resistance explainedWill the glass scratch?
Unlikely. Sapphire is second only to diamond in hardness and shrugs off everyday marking.
Sapphire, mineral and acrylic comparedDoes 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 comparedIs it a men's or women's watch?
Listed as unisex, and at this size it suits any wrist that takes the dimensions.
