Independent examination

Know more about the watch.

Two ways to examine the evidence. A documented report with clear findings, scope and limitations.

Online photographic authentication

$100

A careful review of photographs, identifying marks and available documentation. Useful as an initial assessment or before committing to a purchase.

Visible case, dial, hands, crown and bracelet details
Reference and marking consistency
Written findings, image references and next steps

No physical examination or internal verification. Concealed parts and sophisticated alterations can remain undetected. A report may be inconclusive.

Request photo authentication

Physical / in-person authentication

$300

An examination of the watch itself, by appointment or approved mail-in arrangement, with a documented report.

External condition, identifiers and component consistency
Accessible movement examination when opening is authorized and safe
Recorded scope, findings, limitations and conclusion

Full disassembly, pressure testing, material assays, appraisal and repair require a separate agreement. Shipping and the optional kit cost extra.

Request physical authentication

Before you buy

A second look before a decision.

Send the listing, claimed reference, clear photos and purchase or return deadline. For a physical examination, we coordinate intake with the owner’s permission. Confirm our timing before relying on a seller’s return window.

Photo review cannot establish that a seller will deliver the pictured watch. We do not offer escrow or guarantee seller refunds.

What your report includes

A reference and date; watch or image identification; evidence and components examined; observed inconsistencies or replacement parts; tests performed, if any; limitations; and a reasoned conclusion with recommended next steps.

Possible conclusions include evidence consistent with the claimed identity, observed inconsistencies, or insufficient evidence. A compatible serial number is never enough on its own.

Prepare the evidence

Identify the brand, reference/model and known modifications.
Supply clear front, back and side/crown photos. Provide serials privately when relevant.
Tell us whether you own the watch or are considering a purchase, and confirm permission to share evidence.
Review the terms, then wait for scope, fee and timing confirmation.

Do not open a watch yourself to obtain a movement photo. A qualified watchmaker can provide one when appropriate.

An independent opinion, with defined limits.

We are not a manufacturer-authorized authentication center. The report does not establish legal ownership, stolen status, market value, water resistance or future condition. Historical dating and routine repair are separate from authentication.
