real PVD isn't a coating that wears off. It changes the surface to one that's harder than the original steel. That's why it's used for expensive drill bits, etc. By that definition, I wonder why certain "PVD" watches can get scuff rash, scratches, and dents as easily,or more easily than common steel cased watches. Maybe the manufacturers are using a technique similar to coating cheap outdoor furniture and not the pricey actual PVD equipment. In fairness, not every black watch has PVD mentioned in its' description; I think watch buyers are just assuming it is PVD or using an incorrect term.
