PVD is a general term encompassing many different type of coating, DLC is one of these types of coating.

For example, if we are talking about DLC, then DLC is the material and PVD is the process of applying it. Think of it as this: PVD is the brush, and DLC is the paint.

PVD (Physical Vapor Deposition) is the method used to deposit thin layers of material (e.g. DLC) by condensation of vapor in a high temperature and vacuum environment.

DLC (Diamond-Like Carbon) and ADLC (Amorphous Diamond-Like Carbon - a specific type of DLC) are vaporised coatings. DLC is done with the bonding of high energy precursive carbon rapidly cooled down on the surface. It is very similar to the process of making synthetic diamonds, meaning that the carbon coating has the same attributes as diamonds. They are extremely hard and very resistant to scratches, thus making the coated metal surfaces more durable. DLC is a very hard coating, but the thickness is also a factor. Generally speaking, the usual coating thickness is just 5 to 10 μm, or 0.005 to 0.010 mm.

Something more to keep in mind, the plating itself is only as good as the post-machine finish and cleaning of the underlying metal. There's also a lot of room for quality in the application itself. Properly done, even good old plating is amazingly durable while crappy DLC is still crappy DLC.

So as far as reps go.... who knows.... it really comes down to prep and method as traditional GP can be very durable as anything like the rep method of the above if its correctly applied...

There are so many variables .... its more a case of try and see... as we all know you could order 2 of the same watch from the same dealer & from the same maker and both could vary dramatically and even be both coated differently... in terms of durability, colour, strength etc etc
