Enter both watch values to see who owes cash and how much balances the trade.
If your watch is worth 8,000 and theirs is worth 10,000, you pay 2,000 cash on top of the swap to balance the trade.
1. Use realistic recent asking/sold context, not fantasy numbers.
2. Adjust for box, papers and condition before balancing cash.
3. Agree who ships first or use a trusted meeting method.
4. Write the final values and cash amount clearly.
How do you calculate a fair watch trade? Compare accepted values, then balance with cash.
Who pays cash in a watch swap? Usually the owner of the lower-value watch.
Should box and papers affect trade value? Yes — completeness changes fair value.
Is an even trade always fair? No, not if market values differ.
