An auction catalogue can describe a watch's visible condition without confirming its ownership history. Before bidding, ask whether the house recorded the serial, compared it with the consignment documents, or searched for existing theft reports.
Read the lot terms before the estimate
Review the condition report, seller disclosures, buyer's premium, collection arrangements, and any return or dispute rules. Auction terms vary by house and sale, so use the current catalogue and ask the specialist about unclear wording.
Request the individual identifier
A reference number identifies a model family; you need the individual watch's serial for a theft-status search. If the number is withheld in the public catalogue, ask whether you can inspect it privately before bidding.
A database result doesn't change the auction contract
Run a search on the verified serial and save the result. A no-match is limited to records searched at that time. It does not authenticate the watch or override the auction terms. If a match appears, contact the house and provider before bidding; do not wait until after payment to raise it.
After a sale, keep the catalogue, invoice, payment evidence, and serial photos together. Ask the auction house for written confirmation of any checks it says it completed.
Resolve the Lot Details Before Bidding
Ask the auction house which serial and records its process covers.
