Morphology

watch + key

The meaning 'a small key used for winding some mechanical watches' is directly and straightforwardly derivable from 'watch' (a timepiece) + 'key' (a tool for winding clock springs). This is a regular noun+noun compound meaning 'a key for a watch' — a compositional pattern common cross-linguistically — so a B1 learner who knows both constituents will readily infer the meaning.

Etymology

Watch key is a small metal key that fits into a square hole on a mechanical watch so you can turn it and 'wind' the spring. That's why the word means 'a small key used for winding some mechanical watches'.
