The DS-7 brings a sporty look to the wrist, and may bring back memories for connoisseurs of historic watches. The design of the new product line is derived from a model from the 1970s, but has taken on a decisively modern appearance – with dynamic lines, fashionable details and optimal resilience.

Materials

Stainless steel

The 316L stainless steel which Certina uses for cases, bracelets and clasps, for instance, is extremely resistant, corrosion-resistant and hypoallergenic. It contains only a very small proportion of nickel, which is not released when worn and therefore does not trigger any nickel allergies.

PVD

PVD is the abbreviation for physical vapour deposition and refers to a modern coating method through which a material, for instance gold, can be transferred in a vaporised form, to a steel or titanium substrate. The result is as fine as it is durable. PVD is resistant, corrosion-resistant and very hard.

PVD

Super-LumiNova®

Super-LumiNova® (SLN) is a luminescent material with phosphorescent properties. In the dark, the SLN type BG W9 used by Certina emits the light stored as a blue shimmer. SLN does not damage your health in any way and is used in coatings on hands, indices and bezels. It progressively loses its phosphorescence in darkness, but automatically regains it under light.

Sapphire crystal

Sapphire watch crystal is made of aluminium oxide power (Al2O3) heated to over 2000°C. The resultant sapphire nugget is cut with great precision into fine slices, trimmed and polished. Sapphire is extremely scratch-resistant, shock-resistant and is very transparent. This is why sapphire crystal is an essential element in the DS Concept and is used by Certina in all of its models to protect the dials.
