The crown is used to wind a watch's mainspring, which provides the 'energy' and power to the watch's internal movement. The crown is used to set the time of the tonneau watch. The crown is used to configure additional components of a watch face like the world clocks or a lunar calendar
So, why is it called a "crown?" As it turns out, the term has royal inspiration, as the round, fluted shape of the winding knob reminded many of the crowns of European royalty, and the name "crown" stuck. Let's get it.
Crown classification
Ordinary crown: Pull out directly to adjust the time. For watches with a calendar, the first gear is for adjusting the calendar, and the second gear is for adjusting the time.
Screw-in crown: it is also called spiral crown. The crown is screw-locked, after turning the crown counterclockwise. Unlock it and you can use it normally. The screw-type crown can effectively improve the waterproof function of the watch, and the crown should be locked after operation.
Crown with shoulder guard: The crown has independent protruding shoulder-like design styles on both sides of the crown. Since the crown is the most vulnerable part of the watch, many sports watches will have a crown shoulder design to protect the crown from being damaged.
Crown with protective bridge: There is a bridge-type protective module on the outside of the crown. This type of crown is mostly used in diving watches, or some special models (such as Panerai), in addition to protecting the crown, there is also a compression crown to play a corresponding waterproof role.
