By checking a particular serial number against this list you should be able to date a watch with reasonable accuracy.However, it is no quarantee as to when your watch was shipped from the factory.
From 1976 Rolex again started dating bracelets but this time with a letter to designate the year and number to designate the month of manufacture.So for instance, from the table below, we can denote that a bracelet stamped F7 was manufactured in July 1981. We offer a unique selection of watch accessories, watch winders, and horological books, as well as providing Expert Watch Repair and Restoration Services that are second to none.We also publish The Rolex Report, a series of critically acclaimed reference books used by thousands of watch dealers, collectors and enthusiasts around the world.If a bracelet has an additional ‘S’ stamped along with the year and date then it is a service replacement.
More recently with SEL (solid end link) bracelets Rolex have been stamping the part number, date code and Rolex crown into the inner part of the end link and so not visible without removing the bracelet. Thus spelling out the word "ROLEX" with the "O" being omitted, to help avert any possible confusion with the number "0".This sequence continued through November 1991, when a new numbering system was introduced utilizing the letters N, C and S, which took them through 1993.Coincidentally, the numbering sequence of any particular Letter from this system (e.g.V000001 to V999999), would in fact also be 1 million serial numbers, and worked well with this system.Furthermore, this list only applies to Rolex Oyster-cased watches, and should NOT be used for Tudor, or vintage non-Oyster Rolex watches.
