A model number can help identify the design, size, or generation of a watch, but it usually cannot tell you whether one specific example has been reported stolen. Many watches share the same reference. A theft check needs a number that distinguishes the individual piece.
Model reference and serial number do different jobs
The model or reference number helps a buyer compare the watch with a manufacturer's catalogue or a specialist's description. The serial number is assigned to a particular watch or component. Brands place serials in different locations, and some watches have separate case and movement numbers.
Do not assume that a number on a warranty card is the serial until you know what the field labels mean. Ask the seller to identify the number and provide a clear image of the engraving. Compare the number you search with the number on the watch itself.
If you only have the model number
Ask for the individual serial before sending payment. If the seller cannot provide it, arrange an in-person inspection with a qualified watchmaker or pause the transaction. A database search using a shared model reference could return no useful result or point to records for a different watch.
A serial search has limits too
Even with the correct serial, a no-match result means only that the searched records did not contain a matching report at that time. It does not verify authenticity, prove the seller owns the watch, or rule out a report in another database.
Find the Individual Watch Number
Use the serial on the watch, not only the reference shared by a model family.
