Put a Rolex reference into the Rolex bracelet guide and it gives you the bracelet that reference actually wears, rather than every bracelet the model was ever offered with. You get the part number, the metal, the lug width and the clasp, and for many references how many links a full bracelet has and how many come out with a screwdriver.
It answers 623 references sold from 2002 on: the 188 in Rolex's price lists since 2022 and 368 more from 2002 to 2021, each taken from Rolex's own documents, plus the ones Rolex never printed a bracelet for, researched one at a time. For 78 older watches it also gives Rolex's own replacement bracelet, from the bracelet tables in Rolex's 2011 US price list.
It helps when you are checking that a watch for sale still has the right bracelet, or when you need a bracelet for a watch that came without one. Further down, the guide explains the seven Rolex bracelets and what the clasp codes mean. Vadim wrote it, and he has traded watches since 2017.
