Stem
The stem connects the crown to the movement and allows the user to wind the watch, set the time, and adjust functions such as the date. It is an important part of the keyless works and must match the movement and crown correctly. Stems are often replaced when broken, worn, cut too short, bent, rusted, or missing.
