Abstract
The rotary vessel is structured having a function movable generally vertical relative to a plane of a wristwatch case, and divided with a plurality of stop points in a movable range in a vertical direction, i.e. a stop point for securing stop stability of rotation and a stop point for rotating the rotary vessel. Due to this, in the case that the rotary vessel is in a rotatable state, rotation torque can be minimized.
