This completes the assembly of the watch. In this case, in the watch case 1 of the wristwatch assembled in this way, the exterior member 16 and the case body 15 are connected and fixed by the pin member 33, so when the exterior member 16 and the case body 15 are fastened together with screws, In comparison, it is possible to reduce the size, and the disassembly work, reassembly, and maintenance are easier than when the exterior member 16 and the case body 15 are fixed with adhesive or double-sided adhesive tape.

Next, a case in which this wristwatch is used will be explained.
In this wristwatch, in a normal state, each of the plurality of clock movements 12 of the clock module 7 moves the hands 12b above the dial 10 to indicate and display information such as the time. Information is viewed from the outside through the watch glass 6.

In this state, when the plurality of push button switches 5 are pressed, the mode of the watch is switched. That is, when the head 43 of the first operating member 40 is pressed against the spring force of the first spring member 41, the shaft portion 42 slides and is pushed into the small diameter hole 39a of the first through hole 39. It will be done. Then, the inner end of the shaft portion 42 is pushed into the lower case 17 and presses the contact portion 7c of the timepiece module 7 to operate the switch.

In this way, when the head 43 of the first operating member 40 is pushed and the shaft 42 slides inside the small diameter hole 39a of the first through hole 39, the first ~The outer peripheral portions of the third packings 44 to 46 slide in elastic contact with the inner peripheral surface of the small diameter hole portion 39a of the first through hole 39. Therefore, high pressure waterproofing between the shaft portion 42 of the first operating member 40 and the small diameter hole portion 39a of the first through hole 39 is achieved by the first to third packings 44 to 46.

That is, in this push button switch 5, heat resistance and chemical resistance are ensured by the first packing 44 made of fluororubber to prevent infiltration of liquids such as oil and chemicals, and the second packing 44 made of nitrile rubber has less permanent deformation due to compression. The packing 45 ensures abrasion resistance, durability, and slidability to prevent water from entering, and the third butyl rubber packing 46 ensures heat resistance and weather resistance to prevent the entry of gases such as water vapor. By preventing the watch glass 6 from fogging up, high pressure waterproofing can be achieved.

In this case, the plurality of packings 44 to 46 are arranged in the order of the first packing 44, the second packing 45, and the third packing 46 from the outer end side to the inner end side of the shaft portion 42 of the first operating member 40. It is located in Therefore, in the push button switch 5, the first packing 44 reliably prevents liquids such as oil and chemicals from entering, then the second packing 45 reliably prevents water from entering, and finally the third packing 46 This reliably prevents gases such as water vapor from entering, thereby preventing the watch glass 6 from fogging up. Thereby, the pushbutton switch 5 can be waterproofed to high pressure efficiently, reliably, and satisfactorily.

On the other hand, when operating the switch device 4 to adjust the time or the like, the second operation member 51 is first unlocked by the lock portion 52. That is, in a locked state where the male thread 52a of the cylindrical member 50 and the female thread 52b of the operating head 54 are screwed together, when the operating head 54 is rotated and the female thread 52b is separated from the male thread 52a, the male thread 52a and the female thread 52b are separated. The lock will be released.

Then, the operating head 54 is pushed out of the lower case 17 by the spring force of the second spring member 56, and enters the neutral state. At this time, even if the cylindrical shaft 54a of the operating head 54 slides, the connecting piece 55 does not move and maintains a stopped state, and the connecting piece 55 idles relative to the operating head 54. Rotation of the operating head 54 is not transmitted to the operating shaft 53. Therefore, in this neutral state, no corrections are made to the time or the like.

In this neutral state, the operating head 54 is further pulled out toward the outside of the lower case 17. Then, the cylindrical shaft 54a slides, and the connecting pieces 55 engage with each other within the cylindrical shaft 54a, and the connecting pieces 55 become in a state of rotating as the operating head 54 rotates. When the operating head 54 is rotated in this state, the operating shaft 53 is rotated by the connecting piece 55 to operate the timepiece movement 12 in the timepiece module 7. This allows the time etc. to be corrected.

Further, in this switch device 4, when the operating head 54 is pushed in and is locked to the cylindrical member 50 by the lock portion 52, when the operating head 54 receives an external impact, the cylindrical member The lower case 17 receives an impact via the shaped member 50, and the inner circumferential portion of the lower case 17 is pressed against an impact receiving portion 57 provided on the metal upper case 18.

Therefore, even if the operation head 54 receives an external impact, the impact is received by the impact receiving portion 57. As a result, the operating shaft 53 of the second operating member 51 will not be pushed into the watch module 7 due to impact, so even if the operating head 54 of the second operating member 51 receives an external impact, the operating shaft 53 will not be pushed into the watch module 7 due to impact. Damage to the clock module 7 can be prevented.

In this case, the shock receiving part 57 is provided on the lower surface of the upper case 18 corresponding to the second operating member 51, and is in contact with the inner peripheral part of the lower case 17 in the axial direction of the operating shaft 53, so that it can be operated. The axial deformation of the operating shaft 53 in the lower case 17, which has lower rigidity than the upper case 18, due to the impact received by the head 54 is suppressed. Therefore, the operating shaft 53 is not pushed into the timepiece module 7 by impact.

Further, the outer circumferential surface of the lower case 17 is provided to protrude outward from the outer circumferential surface of the upper case 18, so that when the operation head 54 receives an impact, the lower case 17 receives the impact and the lower case 17 The received impact is reliably and favorably received by the impact receiving portion 57 of the upper case 18.

Further, in this case, the cylindrical member 50 into which the operating shaft 53 of the second operating member 51 is slidably inserted into the second through hole 48 of the lower case 17 is arranged, so that the lower case 17 is connected to the upper case. Even if the rigidity of the second operating member 51 is lower than that of the second operating member 18, the second operating member 51 is held securely and well by the cylindrical member 50. Therefore, the operability of the second operating member 51 is ensured.
