In watchmaking , the crown is a round piece that is turned to raise the watch or put it on time. It is part of the clothing of the watch and as such its design is sometimes very neat. The slice is generally fluted , to facilitate grip, and the back can be engraved with the brand logo.
It is screwed or pushed and adjusts by its barrel in the opposite direction on the winding stem which ensures its sealing.
A crown may be impermeable if its fastening is adjusted by its barrel in the middle part of the box.
