People often receive several numbers after a theft and assume they are interchangeable. They are not. The watch serial is an identifier assigned to the physical watch; a police report or case number points to the record of an incident.
The watch serial identifies the item
A serial can help distinguish one watch from another when it is legible and correctly recorded. Copy it from a reliable source, such as the watch, manufacturer paperwork, or a service record that clearly refers to that watch. Do not substitute a model or reference number.
The report number identifies the case
The case reference helps police, an insurer, or another organization locate its file. It is not a global stolen-property identifier and does not identify the watch by itself. If a form asks for both fields, enter each in the correct place.
Keep them linked in your records
Save the report reference beside the watch's serial, photographs, description, and proof of ownership. When sharing the information, state which number is which. If the serial is uncertain, say so and ask the authority how to update the report once verified.
A database search by serial may return a separate status result. It does not replace a police report, prove a theft, or establish that a watch belongs to you.
Check the Watch Identifier
Use the physical serial for a status search and retain the separate case reference for follow-up.
