How buying works
- Tell us your spec. Year, condition, box and papers: we quote against the typical ask for exactly that.
- Reserve it. Nothing is charged. We confirm the exact watch and send you its photos.
- Authenticated before you pay. An independent watchmaker opens it and the serial is checked against a stolen-watch register.
- Every dollar itemized. Our cost, prep, authentication, processing and margin, line by line.
