What is a watch crown?

A watch crown is a small, circular knob located on the side of a watch case that is used to set the time and date, wind the watch, and adjust other functions such as chronograph and alarm. The crown is typically made of metal and is engineered to be water-resistant, especially in diving watches. Some crowns are designed to screw into the watch case for added water-resistance. In addition, the size and type of crown depend on the watch model, style, and brand, and may be decorated with engravings or logos. The crown of a watch is an essential part of its function, and regular care and maintenance can ensure its longevity and prevent damage to the watch mechanism.
