Serial numbers

Recording a watch reference number

A reference describes a model or configuration; a serial identifies an individual watch.

The first check

Is this a case serial, movement number or model reference? Write down the answer and keep the evidence with the watch's serial. If you cannot get a clear answer, pause before paying or transferring the watch.

What to do next

Keep both fields in your inventory and never substitute one for the other.

Keep the original photographs, documents and messages together. A record tied to the exact watch helps you resolve a later question about its history; a vague model description does not.

How to use a database result

Enter the serial exactly as it appears on the watch. If the search finds a reported loss, pause the transaction and follow the instructions attached to the record. If it finds no match, keep doing the other checks relevant to this decision. A clear search cannot rule out an unreported theft, establish ownership or authenticate the watch.
