'wristwatch' originates from English, combining 'wrist' and 'watch', where 'wrist' refers to the joint connecting the hand with the forearm and 'watch' refers to a small timepiece.

'wristwatch' evolved from the combination of the words 'wrist' and 'watch' in the early 20th century as portable timepieces became more common.

Initially, it meant 'a watch worn on the wrist', and this meaning has largely remained the same in modern usage.
