I was wondering if I am able to get a Rolex watch (Oyster) serviced if I do not have the box or the paperwork? It was my grandmothers watch which was passed down to me when she passed away. She purchased it about 20-25 years ago overseas in Asia and have since lost the paperwork and box. I want to get it serviced (she never got it serviced) so I can start wearing it. Would Rolex also add more links/chains if the watch is too small? I know I would have to pay extra but I do not have the pieces and one that watch alone.
