Explore case serial numbers, bracelet clasp codes, and model references. Choose a lookup below.
About the three databases
Case serial: * represents one variable character. Full serials must fit all fixed characters. Prefix matches require at least one overlapping fixed character. A suffix-only pattern is excluded when a short prefix provides no identifying characters.
Clasp code: searches exact codes. A clasp can be replaced and shared codes are common. Numbers such as 97200 and 78200 are bracelet references, not short clasp codes.
Model number: maps reference numbers to watch model names. Enter a full reference (including M127334 or M127334-0001), a numeric base such as 126610, or a model name. Partial reference searches show all matching entries. A model reference does not identify a replica factory.
The model database includes all 1,465 watch configurations in the official English Rolex sitemap retrieved on 17 October 2026, plus a broad historical index. It does not guarantee every historical, regional, prototype or off-catalog reference. These are reference lookups, not authentication registries. Case and clasp sources are community reports. Historical C+ and newer Clean Plus are kept separate. ONE is a reported ARF rebrand, but historic ARF codes are not automatically copied to ONE. Rich, RGF and RCF remain separate labels. Some code records are single-owner reports or disputed seller attributions; read the evidence notes. Exact specimen records describe one published watch, not every serial sharing its prefix. Crossposts of the same specimen are not independent corroboration. Historical repeated serials do not identify modern production. The factory directory includes historical parts labels as well as complete-watch labels. Letters O and I remain distinct from digits 0 and 1; try alternate readings manually where engravings are unclear.
