WATCHCASE TREATMENTS
THERE ARE TREATMENTS THAT CAN ELEVATE THE VALUE OF WATCHCASES:
PLATING
Gold plating is one of the most common treatments. It renders that gold-looking gleam to any metal, although it easily wears off due to daily use and rubbing.
PVD
Physical vapor deposition is applied by spraying in a heated vacuum. Besides being corrosion resistant, it can also imbue golden or dark metal hues.
DLC
Diamond-like carbon is a coating applied by blasting carbon on a metal surface. It’s more scratch-resistant and expensive compared to the other options here.
AR COATING
Anti-reflective coating is only used for the watch’s sapphire crystal. It reduces glare and reflection, since sapphire crystal is more reflective than glass.
