What is the black coating on watches?
The black coating is diamond-like carbon
How are watches coated?
The coating is deposited by PVD, Physical Vapour Deposition
PVD is a process where a physical material is vapourised in a plasma. A chemical reaction takes place and tiny black particles solidify on the surface of the watch. The black diamond-like carbon is named because it has some diamond-like properties.
PVD stands for “Physical Vapor Deposition”. PVD is the chemical process where you bind tiny particles to a surface – in this case, watches. More specifically, the process bonds a small layer of metal compounds to the watch. The metals are vaporized, and in that way bound to the surface in layers, using a heated vacuum.
