Before buying a pre-owned luxury watch, ask the seller for the serial number, where they bought it, the original receipt, the box and papers, and the service history. Then check the watch against a stolen-watch register and get it inspected. A good seller answers all of these without hesitation.
Key takeaways
- You're buying the seller's story as much as the watch. Test it.
- Box and papers help, but only if every number matches the watch.
- A theft check and a physical inspection answer different questions. You need both.
The 10 questions
1. Can I see the serial number on the watch?
Ask for a photo of the number on the watch itself. You'll need it for a stolen-watch search and to match against the paperwork. A refusal ends the conversation.
2. Where and when did you buy it?
An authorised dealer, a brand certified pre-owned programme or a known pre-owned specialist is easier to verify than "it was a gift". Ask follow-up questions and see if the story holds.
3. Do you have the original receipt or proof of purchase?
A receipt or bank transaction ties the seller to the watch. It also matters for warranty: a new owner usually has to show the date of first purchase to claim.
4. Is it a full set, and do the numbers match?
"Box and papers" means the original box, warranty card and documents. Check the serial on each against the watch. Papers that don't match are worse than no papers.
5. Has it been serviced, and by whom?
Service records from the brand or an authorised centre add to the watch's history and show who's had it open.
6. Are all the parts original?
Replacement dials, hands or movements change the value. Ask directly, then have it checked. Mismatched parts are a known problem in pre-owned watches.
7. Has it been checked against a stolen-watch register?
Run your own search too. See how to check if a watch is stolen.
8. Can I have it inspected before I pay?
A qualified watchmaker or the brand's service centre can confirm what you're buying. Some brands run certified pre-owned programmes; Rolex, for example, authenticates eligible second-hand watches through its authorised retailers and adds a two-year international guarantee.
9. How do you want to be paid?
Use a traceable payment method. Pressure to pay in cash or rush the deal is a warning sign.
10. Does the watch have a digital passport or Shado module, and will you transfer it?
If it does, verify it before you pay. On a watch with a Shado module, tap it with the Shado app to see its registry status. The seller then starts the transfer in their app and you confirm it in yours. For an in-person sale, confirm the transfer before the watch changes hands.
Answers that should stop the sale
| Seller says | What it suggests |
|---|---|
| "I'll send the serial after you pay" | They don't want you to check it |
| "No receipt, it was a gift" (and no other history) | You can't trace where it came from |
| Papers with a different serial | The papers belong to another watch |
| "No time for an inspection" | They're relying on you not checking |
Frequently asked questions
Is a watch without box and papers worth buying?
It can be, but you're relying more on inspection and the seller's history. Expect to pay less, and check it harder.
Can box and papers be faked?
Yes. That's why the serial on the papers must match the watch, and why a physical inspection still matters.
What does a Shado tap confirm?
That the Shado module is genuine, its registry status, and whether a tamper has been recorded. It doesn't confirm that every part of the watch is original, and it never shows who the owner is.
