**DLC** stands for //Diamond-Like Carbon// and denotes a surface coating of watch cases.

===== Overview =====
A surface treated in this manner is blacker than [[ruthenium]] and more abrasion resistant than [[PVD]]. The DLC coating is popular because of its hardness, the deep dark color and its [[allergy|hypoallergenic]] properties. It combines the property of [[carbon]] in its adamantine modification (extremely hard, non-conductive, chemically languid) with that of graphite (the black elastic form of carbon).

The technically sophisticated DLC is applied in several thin layers with a high-tech vacuum process. The extremely low friction coefficient and the degree of chemical inertness give it excellent resistance to scratches, abrasion and corrosion as well as flexible hardness.

[[Breitling]] refers to DLC as "Blacksteel".
