The four-point process
The case is opened and the calibre verified against manufacturer specification by an in-house watchmaker, checking finishing, serial consistency and service condition.
Every component is cross-referenced for period-correct parts, correct hallmarks and any sign of undisclosed replacement or refinishing.
Papers, warranty cards and service history are verified wherever available, and cross-checked against manufacturer production records.
Once a watch passes every check, it is issued a Wynder certificate and sealed for insured transport — only then does it appear for sale.
Why it matters
Counterfeiting in the secondary watch market isn’t a fringe issue — it’s the single biggest barrier to buying online with confidence.

Who does the checking
Our authentication team is trained across major manufacturer movements and combines hands-on watchmaking experience with the same market data used to price every listing.
Authentication happens entirely within Wynder’s own labs — no third-party inspection, no gaps in accountability.
Specialists are trained across the movements, materials and hallmarks of every major brand we list.
Each watch’s authentication record is retained, so provenance is never in question after the sale.
