DLC (Diamond-Like Carbon) is a particularly hard carbon coating that gives the case of the Ternos Professional Black Rock exceptionally high scratch resistance and durability. The deep black surface not only creates a striking look, but also reliably protects the watch from daily wear and tear - whether on land or under water. The elegant matt finish of the DLC plating emphasises the uncompromising design of the Black Rock and makes it the ideal companion for anyone who wants to combine maximum performance with stylish restraint.
