meaning no one else wore the watch. Sometimes gold watches, which are a very soft metal can get an abrasion(s) from the plastic touching the watch, particularly if the watch moves a bit in the plastic or possibly if the sealed watch is handled, eg to show someone or for photography/inventory purposes, etc. 5976G is a heavy gold bracelet watch which can increase the possibility of a minor abrasion(s). So, I think it most likely your AD has not done anything untoward. That said, if the abrasions bother you I am confident Patek will take care of the issue by making the case perfect. If so, probably best that it is shipped back to you, packaged in a way to avoid a possible repeat of the issue. I hope everything works out for you and look forward to hearing how the issue is resolved.
