The space 18 is formed to be longer than the axial length, that is, the slide length of the operation member 11. Thereby, the communication hole 19 is formed in a size that facilitates the flow of cleaning liquid such as water or detergent into the space 18.

Next, the operation of the wristwatch switch device 8 will be described.
The switch device 8 is provided at the inner end portion of the small diameter portion 12a of the shaft portion 12 when the operation member 11 is pushed out of the watch case 1 by the spring force of the spring member 16 in a normal state. The retaining member 14 contacts the inner peripheral surface of the case body 2.

  In this state, the outer end surface of the head portion 13 of the operation member 11 is located on substantially the same plane as the outer end portion of the housing portion 3 a of the exterior member 3 and is exposed to the outside of the exterior member 3. The portion protrudes outside the case body 2 and protrudes into the housing portion 3 a of the exterior member 3. Thereby, the volume of the space part 18 formed by the head 13 in the accommodating part 3a of the exterior member 3 is maximized. Further, in this state, the inner end portion of the small diameter portion 12a of the shaft portion 12 is separated from the switch portion 7a of the timepiece module 7, and the switch portion 7a is in an off state.

  In this state, when the head 13 of the operating member 11 exposed to the outside from the housing portion 3a of the exterior member 3 is pushed toward the inside of the watch case 1 against the spring force of the spring member 16, the head 13 The inner end surface approaches or contacts the outer surface of the case body 2, and the volume of the space portion 18 formed by the head portion 13 in the housing portion 3 a of the exterior member 3 is minimized.

The switch portion 7a provided in the watch module 7 is pressed. As a result, the switch unit 7a is turned on.

  Further, when the head 13 of the operation member 11 is pushed toward the inside of the watch case 1 against the spring force of the spring member 16, the head 13 is formed in the housing portion 3 a of the exterior member 3. The volume of the space 18 is gradually reduced. For this reason, the air in the space 18 is compressed, and the compressed air is discharged to the outside of the watch case 1 through the communication hole 19 of the cleaning path 17.

  As a result, when the head 13 of the operation member 11 is pushed toward the inside of the watch case 1, the compressed air in the space 18 in the cleaning path 17 passes through the communication hole 19 of the cleaning path 17. By being discharged to the outside of 1, the air pressure in the space 18 is maintained at substantially the same pressure as the atmospheric pressure outside the watch case 1. For this reason, the operation member 11 is smoothly pushed toward the inside of the watch case 1.

  Further, when the operation member 11 pushed into the watch case 1 is pushed out by the spring force of the spring member 16, the volume of the space portion 18 formed by the head portion 13 in the housing portion 3 a of the exterior member 3 gradually increases. growing. For this reason, the air in the space 18 is expanded. As the air in the space 18 expands, the air outside the wristwatch case 1 passes through the communication hole 19 of the cleaning path 17 and the space of the cleaning path 17. 18 is sent into.

  As a result, when the operation member 11 pushed into the watch case 1 is pushed out, the outside of the watch case 1 passes through the communication hole 19 of the cleaning path 17 as the air in the space 18 in the cleaning path 17 expands. Is sent into the space 18 of the cleaning path 17, so that the air pressure in the space 18 is maintained at substantially the same pressure as the atmospheric pressure outside the watch case 1. For this reason, the operation member 11 is smoothly pushed toward the outside of the watch case 1.

  By the way, when foreign matters such as mud and dust enter and adhere to the space 18 and the communication hole 19 in the cleaning path 17 provided between the inner end surface of the head 13 and the outer surface of the case body 2. By pouring a washing liquid such as water or detergent into the washing path 17 and washing it away, foreign matters such as mud and dust can be removed.

  That is, in order to wash away foreign matters such as mud and dust, for example, a cleaning liquid such as water or detergent is supplied from the upper outer end portion of the communication hole 19 a located on the upper side of the watch case 1 in the communication hole 19 of the cleaning path 17. Pour into the space 18. The cleaning liquid poured into the space 18 is discharged from the lower outer end portion of the communication hole 19 b located on the lower side of the watch case 1 in the communication hole 19 of the cleaning path 17.
