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.
This organic material, which Certina uses for particularly precious dials on women's watches, comes from the innermost layer of shell of some molluscs. Iridescent, shimmery mother-of-pearl is very brittle and must be processed with great care, which makes it even more valuable.
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.
