JoyComplex@kpbarbee definitely not an annoying question as I was concerned about that too. I put a small shelf on the inside of the cover that the bezel of the watch sits on. Since the bronze, silver, etc are softer metals than the anodised surface of the watch it shouldn't scuff it. I was thinking of going to a craft store and getting some felt with a sticky backing (and using a hole punch to make a few small felt discs) but so far after examining my watch I haven't noticed that I needed it. I may still do that in the future though.
JoyComplex@kpbarbee They are real metal. I put a link to my blog above that shows the finishing process I used to make the bronze look old.
JoyComplex@Kristinahatch Got the watch cover in raw bronze and it fits the Apple Watch really well. Some preliminary photos are show above.
