What does “Binding Bid” mean?

A binding bid commits the bidder to buy the watch if they win. Once placed it can't simply be withdrawn, and the winning bidder is expected to pay the final price on the stated terms.

Binding bids give sellers confidence that an auction result is real, not a number that disappears when the winner changes their mind. For bidders, it means doing the homework before bidding: studying the photos and description, the set and card date, shipping and payment terms, and any fees on top of the hammer price. Failing to honour a winning bid is treated seriously, and many auction platforms and dealer groups restrict or remove people who do it. The simple rule is to bid only what you are genuinely prepared to pay, rather than bidding high to scare others off.

Example: 'All bids are binding. The winner pays within 48 hours of the close.'
