That said, the durability of either methods depends on a variety of other factors such as quality of the bare metal itself and the application process. PVD coatings are technically less hard, but technological advancements have improved in toughness (and hardness) to withstand daily usage. 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.
