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 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.
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.
