A trade can feel less formal than a sale, but both parties are transferring valuable property. Treat each watch as a separate item to verify and document.
Record each watch independently
For both pieces, note the brand, reference, serial, condition, accessories, and agreed value. Photograph the watches and compare serials with supporting documents before handover.
Run separate status and authenticity checks
Search each individual serial and retain the dated results. A no-match for one watch says nothing about the other. Arrange independent authentication and condition assessment when appropriate.
Write down the exchange terms
Identify both parties and watches, any cash difference, delivery or handover date, and what happens if a serial or status issue arises. Do not rely on a message that says only “trade accepted.”
If either party will not provide enough information to identify the watch, delay the exchange. A trade does not make a problematic serial disappear; it transfers the uncertainty to someone else.
Check Both Pieces
Run a separate search for each verified serial before agreeing to the exchange.
