If you're considering a used TAG Heuer, find the serial on the actual watch before paying. A model name such as Carrera, Aquaracer, or Monaco doesn't identify an individual example for a theft-status search.
Ask for the serial and its records
Request a clear photo of the engraving and compare it with the seller's card, invoice, or service papers. If you can't locate the number, ask a watchmaker. Don't enter a reference number just because it's the only number in the listing.
Check before funds are released
Run a search on the verified serial and save the date. A match means pause and contact the service; a no-match means the searched records had no matching report at that moment. Neither result authenticates the watch.
Complete the purchase file
Get a receipt that records the serial, price, seller, and condition. If the watch you receive has a different serial, contact the seller or platform promptly; the earlier result does not transfer to a different piece.
