Technology can help answer two different questions about a pre-owned watch: whether its serial number has been reported lost or stolen, and whether the watch itself is genuine and in the configuration it claims to be. A database check can flag a report; it cannot certify authenticity or prove clear ownership. For that, buyers may need records, a reputable seller, and inspection by the brand or a qualified specialist.
What a watch check can—and cannot—tell you
Counterfeit detection and stolen-property screening overlap in resale, but they are not the same process. A stolen-watch search compares an identifier, usually a serial number, with reports held by a service. Authentication assesses the physical watch and its parts, construction, and provenance. A watch can be genuine but stolen, counterfeit but not listed as stolen, or altered in ways that make its identity or originality disputed.
| Check | Question answered | Typical evidence | Important limit |
|---|---|---|---|
| Lost-or-stolen database search | Has this identifier been reported lost or stolen in the records searched? | Serial number and registry records | A clear result is not proof of authenticity or ownership; reporting may be incomplete or delayed. |
| Brand or expert inspection | Is the watch genuine, and does its condition or configuration meet the stated claim? | Physical inspection, reference and serial details, and service or ownership documents | Authority and scope depend on the brand or specialist and the service offered. |
| Seller and provenance review | Is there a credible chain of ownership and a reliable route to recourse? | Seller identity, purchase records, service history, and applicable guarantees | Documents and digital records still need to be credible and linked to the physical watch. |
A serial number, QR code, NFC tag, blockchain entry, or certificate image is only as useful as the link between that record and the actual watch, the integrity and freshness of the record, and the authority of whoever verified it.

Enquirus: registration and search
Richemont announced Enquirus on 30 March 2023 as a digital platform intended to help address watch and jewellery theft. Owners can register items using brand and serial numbers, store documents in a digital vault, and report items lost or stolen; prospective buyers and industry partners can search the platform. Richemont said access was free for customers and industry partners. Its launch announcement cited more than 175 luxury watch brands pre-loaded and over 28,000 watches and jewellery registered as lost or stolen at that time. Those are historical launch-period figures, not current totals. Richemont’s Enquirus launch announcement.

The Watch Register: serial-number checks
The Watch Register describes serial-number searches for Rolex and other brands, use by law-enforcement agencies, and cross-border recovery work. It reports that 50% of watches it recovered were found within one year of theft and 35% within six months. These are the service’s own reported figures; the cited source does not provide an independent comparative evaluation. The Watch Register.
A match is a reason to pause the transaction and contact the database operator or appropriate authorities for guidance; do not assume that a search result alone resolves ownership. A no-match result only means that the search did not find a report in the records available to that service at that time. It cannot rule out an unreported theft, a delayed record, or an identifier that does not match the listing.

How buyers can check a pre-owned watch
- Start with the seller. Prefer an established seller with a clear returns process and verifiable business identity. Ask for the watch’s brand, model or reference, serial details, condition disclosure, and what recourse applies if its description proves inaccurate.
- Ask for supporting records. Request available purchase documentation, service history, and ownership information. Check that details are consistent with the watch and seller; a document or certificate image by itself is not conclusive.
- Use an appropriate lost-or-stolen search. Ask the seller for the serial number privately and check a relevant service where available. Do not post a watch’s full serial number publicly. A result applies to the database searched, not every registry or report worldwide.
- Arrange authentication when the stakes warrant it. Use the brand’s own program where available or a qualified independent specialist who can physically inspect the watch. Clarify whether the service assesses authenticity, originality of components, condition, or all three.
- Keep the transaction evidence. Retain the listing, seller communications, invoice, inspection findings, and any search result so there is a record of what was represented and checked.
Brand-run authentication: Rolex Certified Pre-Owned
Rolex Certified Pre-Owned is a brand-specific route rather than a universal watch-authentication system. Rolex says qualifying second-hand watches must be at least two years old, are authenticated in Rolex workshops, serviced and tested, and are sold by participating official retailers with a two-year international guarantee. Rolex states: “Only Rolex can confirm the authenticity of a Rolex watch.” That is Rolex’s statement about Rolex watches, not a claim about other brands or every resale transaction. Rolex Certified Pre-Owned.

Digital product passports are not a universal watch guarantee
EU Regulation 2024/1781 establishes a general framework for digital product passports, including provisions for unique identifiers and a registry. Product-group requirements depend on delegated acts. The regulation itself does not establish that every watch already has, or must already have, a digital product passport. A digital record should therefore be treated as supporting information, not as a substitute for checking the physical watch and the record’s source. EU Regulation 2024/1781.

How enforcement targets counterfeit sales
Technology is also used to disrupt listings and investigate distribution, rather than only to verify an individual watch. The Federation of the Swiss Watch Industry reported that 1,074,866 counterfeit-watch advertisements were removed from e-commerce and social-media platforms during 2024. It also reported 784 official counterfeit declarations in 2024, compared with 612 in 2023. These figures count enforcement outputs, not the total number of counterfeit watches sold worldwide. Federation of the Swiss Watch Industry, 2024 annual report.
A September 2026 U.S. Department of Justice announcement described a woman charged in a case involving counterfeit luxury watches imported from China and sales promoted through Instagram accounts. The release described undercover purchases at roughly $200–$300 per watch; the charge is an allegation, not a conviction. The example illustrates how online accounts can form part of a sales channel and investigative trail, but it does not establish how common such cases are. U.S. Department of Justice announcement.

- No database match: Treat it as one limited screening result, not proof that the watch is genuine or unencumbered.
- Digital record or code: Verify that it corresponds to the physical watch and comes from a source with authority to make the claim.
- Unclear authenticity or altered configuration: Pause and obtain a physical inspection before paying, especially where the seller cannot substantiate the listing.
