A listing for a Rolex Submariner may show a reference number, but a stolen-status search needs the serial for the specific watch. Ask for the serial before a deposit and make sure it belongs to the piece pictured.
Separate reference from serial
The reference identifies a Submariner model or variant. The serial identifies an individual watch or component. Read document labels carefully; a number on a card isn't automatically the number you should enter in a theft lookup.
Compare the number at inspection
At an in-person inspection, match the engraving to the number you searched and the paperwork. If the bracelet hides it, ask a watchmaker to reveal it safely. A seller's photo is useful only when you can confirm the same number on the watch you receive.
Interpret the result narrowly
A match means pause and verify the record with the service. A no-match means the searched records had no matching report at that time. Neither result authenticates the Submariner or proves ownership.
Keep the search result, listing, receipt, and any inspection notes together. That file will be more useful than a screenshot with no date or serial.
Check the Individual Submariner
Search the serial on the watch, not only the Submariner's shared reference.
