DLC (Diamond-Like Carbon) coating is a thin, diamond-hard film applied to watch components, offering exceptional scratch resistance and a distinctive black finish.
DLC (Diamond-Like Carbon) coating is an ultra-hard carbon-based film rated 7-9 on the Mohs scale, providing exceptional scratch resistance. Applied via PVD process, it creates a distinctive matte black or dark grey finish while being hypoallergenic and corrosion-resistant. Popular on tool watches and tactical pieces.
DLC is extremely durable and wear-resistant, lasting years under normal use. However, deep scratches or impacts can penetrate the thin coating (typically 1-5 microns), exposing the base metal beneath. Once damaged, DLC cannot be easily reapplied without returning to the manufacturer for professional refinishing.
No, polishing removes the DLC coating entirely. The coating is harder than polishing compounds but thinner than the base metal, so any abrasive polishing will wear through it. DLC watches should only be cleaned with soft cloths and mild soap—never polished or professionally refinished unless recoating.
