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.
Aluminium is very neutral, hypoallergenic, corrosion-resistant and temperature-resistant. However, above all, it is extremely lightweight: three times lighter than stainless steel and around one and a half times lighter than titanium. These are some of the qualities used by Certina for manufacturing extremely lightweight cases and clasps. The brand uses anodised aluminium only. Not only does this extremely durable protective layer enable the material to be additionally hardened, it allows it to be produced in any colour chosen by the designers.
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 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.
