PVD is the abbreviation for “physical vapor deposition”. This is a method by which a wide variety of materials can be vaporized steel, aluminum, gold, silver, platinum, tin, nickel, chromium, copper and oxides. More precisely ion particles from the source material of the watch are exchanged through ones with “different color”.

PVD-coated materials achieve excellent coating properties

• High hardness, about 2 to 4 times the hardness of hardened steel
• Smooth surface
• The surface structure is maintained
• Good adhesion
• High density and homogeneity
