Can't speak of the HBB as I've yet to own one, but I can speak of PVD coatings in general. I've own/owned a couple of gen PVD'd watches and I can definitely say that they DO scratch. When the scratch is deep enough you can see the SS. One bad thing about that is that you can't just touch up scratches on PVD coating. So unfortunately you're stuck with it. Of course, you could have it redone, but that would/'could be expensive.
