Crown

The knob on the side of a watch used to set the time or wind the movement.

Extended Explanation:
The crown serves as the interface between the wearer and the movement. Depending on the type of watch, it may be used for winding, setting the date, or adjusting additional functions. Screw-down crowns, commonly used in dive watches, provide water resistance. Iconic watches like the Rolex Submariner feature the brand’s patented Triplock crown system for enhanced protection.
