Here is a good write-up on PVD process:

It is supposed to make a watch less apt to corrosion. It's being used more frequently in diver's watches but has made it's way into fashion watches for the "black out" look.
Most PVD watches do not look as shiny black as s15driftking's. IMO the better looking PVD watches have a sort of sandblasted treatment done first. The one that s15driftking almost looks ceramic (which some watches have been made from and Rolex has been using ceramic in it's bezel's). Stuhrling's seems to have a few models which are made to look like other popular makers, Omega, Rolex, Breitling, Hublot, etc. So I can understand the comparison.
s15driftking is your quartz or automatic? And does the 53mm measurement include the pushers and crown? I ask because it does not look that large on your wrist.
