The DA 34 BLACK version is provided with the extremely hard, 5-7 microns thick, multilayer DAMEST® coating.The foundation is the basic material made of martensitic stainless steel with a hardness of about 740 HV. An approximately 1.5 microns thick and 1500 HV hard ion implantation zone is formed as an intermediate layer, which functions as an anchorage of the multilayer coating on the base material. This special technology prevents the flaking of the black layer to a large degree.The black case and the dark dial form a uniform contrast against the red design elements and the red embroidery on the watch band.
