Patented DAMEST® Coating
The black DAMEST® coating is, above all, responsible for combining the three qualities of extreme strength, scratch resistance and flexibility together as optimally as possible for the longevity of the watch and its resistance to scratches. DAMEST® is an abrasion-proof, 7 μm-strong multi-layer coating which sticks to the hardened casing in an optimal manner due to the ion implantation layer, which it uses as an anchor. Additionally, it reliably prevents any breakage in the casing due to a universal tempering of around 710 HV (hardness as per Vickers testing). The ice-tempered stainless steel thus constitutes a stable, shock-resistant background. At the same time, the combination of carrier material and casing in a multi-level structure ensures for a special kind of elasticity, which can compensate for knocks up to a certain point.
