Crown The winding crown is a small knob or lever located on the side of a watch. It is used to manually wind the mainspring of the mechanical watch movement. The winding crown is also used to set the time and date on mechanical watches. It is typically located at the 3 o’clock position on the watch and is often decorated with small grooves or ridges for gripping. To wind the watch, the crown must be pulled out to an extended position and then rotated clockwise until the watch is fully wound.
