Here we have a complete clasp for a Rolex Oyster Bracelet #93150. This would have come on a 16610. These had the lined flip lock. The two lines running through the flip lock matches the clasp. These are getting very hard to find in any condition. This one is used, untouched, but still good and working as it should. It also has its complete diver’s extension. Please see pictures for real condition.
