The element, sometimes positioned on the aspect of a timepiece’s case, is a knurled knob used to govern the arms and alter different features. It serves as the first interface for setting the time, date, and typically winding the mainspring in mechanical actions. Examples embrace adjusting the hour and minute arms, advancing the date show, or replenishing energy in a manual-wind watch.
This seemingly small element is essential for the performance of many timepieces. Its design influences the water resistance of the case and the convenience with which the wearer can work together with the watch. Traditionally, its growth mirrors the evolution of watchmaking itself, from easy winding mechanisms to extra advanced methods built-in with problems.
