Pawn refers to a way to give property to pawn institutions as collateral to obtain loans. Watches, as valuables, can be used as chess pieces. According to the regulations of pawn institutions, the pawn value of watches is usually a certain proportion of their market value, generally 50% to 70% of the market value. So you can pawn 3000 watches, and the amount of pawn may be between 1500 and 2 100.
