Before you buy

Check the seller's authentication process, ask for photographs of the actual piece (never catalogue images), and confirm what the price includes: box, dust bag where relevant, receipts, and any service history for watches.

Our own process

We combine machine analysis with manual expert review, and publish a condition report on every listing. Any piece proven inauthentic is refunded in full.

Frequently asked questions

Is second-hand luxury a safe purchase?
It is when the seller authenticates every piece, photographs the actual item and publishes a condition report. Those three points are the practical test.
