Crown

A crown is the external control used to wind the movement, set the time, and adjust functions such as the date, depending on the watch. It also contributes to the appearance, usability, and water resistance of the case. Crowns are often replaced when worn, damaged, missing, difficult to operate, or no longer fitting the stem or case tube correctly.
