So this is a brand new watch but out of warranty? Hmmm... so it is several years old. Have you owned it the entire time and just now started to wear it and remove the plastic?
Just stating my opinion, I do not believe that watch left the AP Factory with those marks on the caseback. How they got on there, when and where, I can't speculate. I see other marks in the sand blasted bottom finish too. It seems to have been worn and scratched by someone.
