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.
Claims20
A watch case comprising:
- a case body;
- a bezel movably mounted on the case body for sliding movement between upper and lower stop positions and for rotational movement when the bezel is in the upper stop position;
- and a ring interposed between and extending circumferentially around the bezel and the case body, the ring having one or more first portions engageable with the bezel to prevent rotational movement thereof when the bezel is in the lower stop position, and one or more second portions engageable with the case body to prevent upward sliding movement of the ring when the bezel moves from the lower stop position to the upper stop position.
