![]() ![]() In our experience, it holds up well to daily wear and tear. In fact, a DLC coat typically uses the PVD process for application.ĭLC touts to be the hardest form of black coating ever to exist (equivalent to the hardness of sapphire). The result is a smooth and even coat – perfect for precision parts such as watches. (TAG, for instance, uses titanium carbide on their black-finish watches.) That material is then deposited on the case which forms a molecular bond to the metal surface. It is done by vapourising metal compounds to the watch case, layer by layer, in a heated vacuum. The second and perhaps most commonly used method is Physical Vapour Deposition (PVD). It involves blasting carbon onto the watch case and then supercooling it, resulting in a strong bond to the stainless steel/titanium surface. ![]() The first method is a coating: DLC, short for “Diamond Like Carbon. Sidebar: There are broadly 2 options to treat metals to achieve a black appearance, apart from using outright carbon itself. The titanium case is lightweight and offers a nice heft while on the wrist.
