Physical Vapor Deposition (PVD) has been around for decades primarily in military applications original designed to decrease friction wear on metal parts. It bonds a micron thick layer of metal compounds to metal or other materials. Why PVD? First off the finish won’t wear off. It reduces wear of bracelets, crowns, bezels, etc.Adds a unique professional appearance to your timepiece and virtually eliminates reflective glare. As the deposition process is so flexible many industries have begun using the technology. Tooling for example on metal cutting lathes increases the life of all sorts of parts from the lathe bed to the cutting tools.

Because PVD reduces friction between metal parts less lubrication is necessary and temperatures are generally lower than without coatings. Though PVD coatings are typically only a few microns thick the molecules bond to the surface of the metal in such a way that they are very difficult to remove once applied. This long lasting resilience is what makes PVD so attractive for thousands of mechanical applications.
