This Tudor Sub is an easy 90%+ piece and is all original. It is a 63XXX serial, dating it to the early eighties. Serial and model are crisp between the lugs. The original tritium dial, hands and bezel pip have a lovely and even light patina. Trip-lock crown screws down perfectly and the bezel is smooth. Bezel insert has very minimal marking or wear. The original folded link 9315 bracelet with 380B end links is in great shape with minimal stretch, and will comfortably fit up to an 8" wrist. Clasp and dive extension are nice and crisp. Watch case has some surface wear consistent with age, and has never been polished. Bracelet also has a few surface marks but is in very nice shape. Original acrylic crystal is also in great shape. It has some very light marking...the sort of stuff that comes out with a few minutes rubbing with some polywatch. Watch comes with its original box, hang tag (With serial number matching the watch) and Tudor brochure...but no warranty papers.
