Physical Vapor Desposition is a process
that involves high temperature vacuum
evaporation or plasma sputter bombardment
rather than involving chemical reaction.
Mini e-beam evaporators can deposit
monolayers of virtually all materials with a
melting point of 3500 Celsius.
In laymen terms,PVD is much more
durable than electro-plating.
PVD still scratches and shows the base metal beneath the surface! As to gold on watches, nothing holds up to the old "gold filled" standard where the minimum was 70 microns (1/20) of an inch...now you know how minuscule and thin the much touted 5 micron PVD standard is.
And in response to another post which stated,"Pvd will hold up to normal watch wearing quite well."....that's the problem. Most of the Black or "stealth" PVD watches are supposed to be SAR type.
I confess....I, for the most part, dislike PVD watches because they do not hold up well under truly normal wear & tear.
These watches were not even meant for "normal wear"! Most of us have forgotten what "Normal wear & tear" is because we wear a watch for a couple of days or a couple of hours and then it goes back in the box for weeks waiting for it's next shot in the rotation. "Normal" wear & tear, to the average guy means putting the watch on and taking it off several year down the road while he does the yard work, fixes his car, plays football and cleans the pool!
It's not his "beater"...it's his watch!
