Given that you bought four Pateks from this AD last year, you are a VIP and it is unbelievable that this AD could have intentionally sold you a scratched-up watch.
Hence, I would give the benefit of doubt to the AD and expect an exceptional answer and solution. If your problem is not addressed to the fullest extent, then IMO you should take all means available to you for redress
Hope everything works out soon.
Cheers,
