PVD coating. Someone have/has a rose gold or black (or other color) PVD coating watch. EDOX, Longine, Tissot, SEIKO quality level? SUN UV, chemistry, salt, sweat e.t.c. damage it for a time. And on the cheap watches specifically made from brass zinc e.t.c. with cheap PVD tech and a thin layer of PVD, it damage very quickly. How long does it hold up if watches are used each day? But, for example, in the office? If they are not used in the field, or building, engine repairing e.t.c. Particularly, I'm curious how EDOX PVD holds up during the years of use. Thanks.
