Next, the structure and the like of the above-described external operation device 10 will be described.

The external operation device 10 has a structure as shown in FIGS. 2 to 5, and is provided in the case 2 around the center axis CL of the wristwatch 1. The external operation device 10 is for performing a movement operation of the movement 5 arranged inside the case 2, particularly, the contact spring 7 along the T direction.

The case 2 has a hole 2a. This hole 2a is formed along the center axis CL,
It connects the outside and inside. A hollow guide member 20 is fitted into and fixed to the hole 2a. As shown in FIG. 2, the guide member 20 is
The guide member 20 has a large-diameter portion 21 and a small-diameter portion 22. The inner diameter d1 of the large diameter portion 21 of the hollow or pipe-shaped guide member 20 is set to be larger than the inner diameter d2 of the small diameter portion 22.

The guide member 20 is firmly fixed to the case 2 by brazing or a heat fusion portion 2c or the like.
There is no rotation about L. The guide member 20 can be made of metal or plastic.

The external operation device 10 is called a button in the examples of FIGS.
Is the button axis (operation axis) 31 and the button body (external operation body)
32 and the like. The button shaft 31 can be made of, for example, metal or plastic, and has a button body 32.
Is made of metal.

The button shaft 31 has a shaft portion 33, a flange portion 34, a retaining ring 35, and a waterproof packing 36, as shown in FIGS. The waterproof packing 36 is the shaft 3
It is embedded in the middle of 3. The stop ring 35 is fixed to the distal end side of the shaft portion 33, and the shaft portion 33 is further extended from the state shown in FIG.
It stops so as not to move in one direction.

The flange portion 34 of the shaft portion 33 and the guide member 2
A spring 23 is arranged between the inner bottom surfaces of the large diameter portions 21 of the zero. This spring 23 moves the button shaft 31

The engaging means 38 is an engaging portion formed inside the grip portion 36a, and can be detachably engaged with an engaging means 39 formed on the outer peripheral surface of the large diameter portion 21 of the guide member 20.
The engagement means 38 and 39 are engaged by screws or bayonet or the like.

Since the button body 32 is exposed or exposed to the outside of the case 2, for example, a material such as gold, which is an expensive metal, can be employed, but the button shaft 31 is exposed to the outside. No ordinary relatively cheap metal or plastic can be used.

As described above, the external operation device (button) 10 as a button is constituted by the two members of the button shaft 31 and the button body 32. Since the material to be adopted can be appropriately selected, particularly, only the button body 32 exposed to the outside can be made of an expensive metal. Therefore, the cost of the external operation device 10 can be reduced.

Next, an example of operation of the contact spring 7 of the movement 5 by the above-mentioned external operation device 10 will be described with reference to FIGS.

FIG. 2 shows a state in which the engagement means 38 of the button body 32 is not engaged with the engagement means 39 of the guide member 20 and the lock of the button body 32 is released. In this state, the flange portion 34 of the button shaft 31 is

Thereby, the button shaft 31 can press the contact spring 7 of the movement 5 to make electrical contact with the contact 5 a of the movement 5.

The above-mentioned external operation device 10 includes the button body 3
2 and a button shaft 31. Accordingly, the button body 32 is exposed to the outside, so that it can be made of relatively expensive metal, and the button shaft 31 located inside can be made of inexpensive metal, plastic, or the like. Therefore, the material cost of the external operation device 10 can be reduced.

Further, even if the user drops the wristwatch 1 of this type, for example, and an external force is applied to the button body 32 exposed to the outside, the button body 32 and the button shaft 31 are separated from each other. Therefore, when the external force is applied to the button body 32, the external force is not directly applied to the button shaft 31. Therefore, the button packing 31 is not deformed by the external force at the waterproof packing 36. Therefore, the waterproof function between the button shaft 31 and the guide member 20 can be maintained.

As described above, by forming the external operation device 10 separately from the button body 32 and the button shaft 31, restrictions on strength, shape, and cost can be reduced. The button body 32 is an exposed portion of the external operation device 10 and also has a fixing function using the engagement means 38 and 39. On the other hand, the button shaft 31 has a contact sliding with respect to the contact spring 7 of the movement 5 and a waterproof function by the waterproof packing 36.

By changing the material and shape of the button body 32 appearing on the exterior of the case 2, design variations can be expanded, and the button body 32 can be made of an expensive metal such as 18K. . As described above, the button body 32 which is the outer peripheral portion can be fixed to the case 2 side or the guide member 20 fixed to the case 2 by using the engaging means 38 and 39 as described above. The shaft 31 is not affected by an external force, so that erroneous input of the contact spring can be prevented and waterproof processing can be achieved.
