Abstract

A timepiece according to an embodiment makes it possible to rotate a crown even when the crown is locked using a non-design-restricting structure and comprises: an outer case having a built-in movement and a crown hole in a portion of the outer case that penetrates from the inside to the outside; a crown for operating the movement; and an engaged member connected to the outer case. The crown comprises: a shaft part that is inserted into the crown hole and connected to the movement; an operation part that holds the shaft part such that movement along the axial direction of the shaft part is possible and makes it possible to rotate the shaft part in the circumferential direction; and an engagement part that is disposed between the engaged member and the operation part, restricts the movement of the operation part in the axial direction when engaged with the engaged member, and rotatably holds the operation part whether or not engaged with the engaged member.

Description

technical field

[0001] The present invention relates to timepieces. Background technique

[0002] In the past, there were clocks with crowns. In such timepieces, the crown is connected to the movement via the stem. Then, the clockwork is driven by transmitting the rotational force generated by the rotation of the watch to the movement to wind up the mainspring of the movement. In addition, in such a timepiece, the crown can be pulled out, and the user of the timepiece can rotate the crown in the pulled-out state to perform time adjustment operations and the like.

[0003] In such timepieces, in order to prevent unintended operations by the user, some of the timepieces lock the crown on the case through a screw structure or the like to restrict the pulling out of the crown. However, whenever the user wants to wind up the mainspring, he needs to first unlock the crown and then rotate the crown, which sometimes feels cumbersome. Patent Document 1 describes a timepiece whose...
