DLC stands for Diamond-like carbon. It is used for a huge range of purposes spanning many different industries, including aerospace, automotive, military and medical; and now, design-led applications. DLC leaves a beautiful, flawless finish, and is velvety and lubricious to the touch. It exhibits properties as slickness (very insusceptible to friction) and durability. It is also extremely scratch resistand and up to eight times harder than steel.
Being amorphous DLC can be applied to different finishes and it will adopt the same tacticle characteristics of the surface it is applied to (brushed or polished), resulting in a change of colour but retaining its finish. This allows to preserve the subtleties of the contrasting textures of a watch as well as leads to an aesthetically pleasing outcome.
