1. A timepiece comprising:

a case member containing a movement of a timepiece;

a bezel rotatably provided in the case member, including an engaged portion;

a restrictor including an engaging portion which prevents the bezel from rotating when engaged with the engaged portion and allows the bezel to rotate when disengaged from the engaged portion, the restrictor being movable between a restricted position in which the engaging portion is engaged with the engaged portion and a release position in which the engaging portion is disengaged from the engaged portion; and

a holding mechanism which switchably holds the restrictor between a held state and a non-held state, the held state in which the restrictor is held in the restricted position, the non-held state in which the restrictor is moved to the release position,

wherein the holding mechanism includes two operation input units to which independent pressing operation forces are respectively applied, and a release mechanism which moves the restrictor by moving a moving amount independent from a moving amount of the operation input units to switch the restrictor from the held state to the non-held state irrespective of a continuance of applying the pressing operation forces once the pressing operation forces are concurrently applied to the two operation input units.

2. The timepiece according to claim 1 ,

wherein the restrictor is rotatable around a shaft, and

the restrictor is moved between the restricted position and the release position by being rotated around the shaft.

3. The timepiece according to claim 1 ,

wherein the release mechanism includes an elastic operation member containing an elastic member and having a pair of end portions biased by the elastic member to be axially extended, and an engaging members having engaging holes into which the pair of end portions are respectively fitted when the restrictor is held in the restricted position, and

the two operation input units are respectively placed on extension lines of the end portions of the elastic operation member.

4. The timepiece according to claim 3 , wherein each of the engaging members includes a taper on an edge of each of the engaging holes.

5. The timepiece according to claim 4 ,

wherein the case includes a pair of legs,

terminal ends of the elastic operation member are in direct contact with the pair of legs, and

the engaging members are separately formed from the pair of legs and attached to the legs respectively.

6. The timepiece according to claim 3 , wherein the restrictor is returned to the held state when the pair of end portions of the elastic operation member are respectively fitted into the engaging holes by receiving an operation force to move the restrictor from the release position to the restricted position.

7. The timepiece according to claim 1 , wherein the release mechanism includes a restriction-release biasing member which biases the restrictor to the release position when the restrictor is held in the restricted position.

8. The timepiece according to claim 1 , wherein the two operation input units are provided to receive the pressing operation force from a direction orthogonal to a moving direction of the restrictor.

9. The timepiece according to claim 1 ,

wherein the engaged portion includes a plurality of protrusions and depressions formed along a circumference of a bottom surface of the bezel, and

the restrictor includes at least one of convexes that engage with the depressions or concaves that engage with the protrusions.

10. The timepiece according to claim 1 , wherein the restrictor includes a release-state indicator which is at least partially hidden from view when the restrictor is in the restricted position and is viewable when the restrictor is in the release position.

11. The timepiece according to claim 1 ,

wherein the restrictor is placed in a position of the case member corresponding to 9 o'clock of the timepiece,

the two operation input units are provided on a 9 o'clock side of the timepiece and are separately arranged below and above the 9 o'clock position on the timepiece, and

the two operation input units are placed more inside the case member than a 12 o'clock-side end and a 6 o'clock-side end of the timepiece in plan view.

12. The timepiece according to claim 1 , wherein the release mechanism moves the restrictor in a direction to apart from the operation input units.
