How should I read the price?
A retail reference comes from an identified external store. An ask is a seller’s requested price; a bid is a buyer’s offer. Neither proves a completed sale. An empty market estimate or history means that data is unavailable, not that the watch has no value.
How prices and market data work →What should I check before buying?
Confirm the exact reference, photographs of the actual watch, condition, service history, included box and papers, seller identity and total delivery cost. Check the manufacturer’s guidance before relying on the stated water resistance for a used watch.
