For a long time on my wishlist but now on my wrist. Serial: 24m. Bracelet is a 1171 and what I can find is that 663's are the endlinks which should fit. Imho the fit is pretty sloppy? Or do I miss something?
..The end links look bent out of shape some; .perhaps with a little tweaking- they will fit much better..
I believe the 633 endlinks are not a great fit as the 516 endlinks were better IMO. Those look like newer replacements as they are laser etched instead of engraved.
I would get a new set and start over - file them to fit and you can usually get a pretty tight fit - takes time and patience though. Cheers, Al
