By moving the first small needle 11a attached to the upper end portion of 15a and the second small needle 11b attached to the upper end portion of the second small needle shaft 15b above the second dial plate 10, respectively. , Configured to indicate world time.

Next, the operation of such a wristwatch will be described.
Usually, as in the first embodiment, the first timepiece movement 12 moves the hands 7 above the first dial 6 to indicate the current time. At this time, the second hand movement 13 causes the function hand 11 to move above the second dial plate 10 to indicate the time of the selected city among the cities in the world in world time. On the other hand, the liquid crystal display unit 30 electro-optically displays information such as time, date, day of the week, etc., and the displayed information is passed through the second opening 35 b provided in the first dial 6 and the watch case 1. Visible from above.

  In this case, the function hand 11 that moves on the second dial plate 10 moves below the pointer 7 that moves above the first dial plate 6. That is, as shown in FIG. 10, the second dial plate 10 is disposed corresponding to the first opening 35a of the first dial plate 6 in a state of being located below the first dial plate 6. Has been. As a result, the first small hand 11 a of the functional hand 11 moves in the first opening 35 a of the first dial 6 above the second dial 10. The second small hand 11b of the function hand 11 is above the first opening 35a of the first dial 6 located above the second dial 10 and below the hour hand 7a of the pointer 7. Move the needle.

  As described above, according to the watch module 2 of the wristwatch, the upper polarizing plate 32 of the liquid crystal display unit 30 disposed on the lower side of the first dial 6 that indicates the time by moving the hands 7 upwards, Since the second dial 10 is provided with a notch 32a, the structure of the liquid crystal display unit 30 and its circuit configuration are not complicated as in the first embodiment. The wristwatch can be made thinner.

  That is, in the timepiece module 2 of the wristwatch, the second dial plate 10 can be disposed in the notch 32 a provided in the upper polarizing plate 32 of the liquid crystal display unit 30. Even if the second dial plate 10 is disposed on the lower side, the upper polarizing plate 32 of the liquid crystal display unit 30 can be disposed close to the lower surface of the first dial plate 6, and thereby the first embodiment and the first embodiment. Similarly, the entire watch module 2 can be thinned, and the entire wristwatch can be thinned.

  Further, in the watch module 2 of the wristwatch, only the notch 32a is provided in the upper polarizing plate 32 of the liquid crystal display unit 30, so that the display electrodes of the liquid crystal display unit 30 do not increase or decrease as in the first embodiment. Since it is not necessary to change the electronic circuit, the structure of the liquid crystal display unit 30 is not complicated, and the circuit configuration of the liquid crystal display unit 30 is not complicated, and can be driven easily and satisfactorily by an existing electronic circuit. it can.

  Further, the timepiece module 2 includes the upper housing 3 in which the first dial 6 is disposed on the upper surface and the liquid crystal display unit 30 is disposed on the lower side of the first dial 6. Thus, as in the first embodiment, the first dial 6 and the liquid crystal display unit 30 are placed on the upper side in a state where the second dial 10 is disposed between the first dial 6 and the liquid crystal display unit 30. The housing 3 can be reliably and satisfactorily assembled, and thereby unitization can be achieved.

  In this case, the timepiece module 2 has a configuration in which the liquid crystal display unit 30 is provided in almost the entire area of the upper housing 3 and the second dial plate 10 is disposed on the liquid crystal display unit 30. 6 and the liquid crystal display unit 30 can be assembled in a compact manner.

  That is, the upper polarizing plate 32 of the liquid crystal display unit 30 is provided with a cutout portion 32 a in which the second dial plate 10 is disposed, whereby the second dial plate 10 is cut out of the liquid crystal display unit 30. Since it can arrange | position favorably in the part 32a, while being able to install the 2nd dial 10 compactly, thickness reduction can be achieved.

  In this case, when the second dial plate 10 is arranged in the notch 32 a of the liquid crystal display unit 30, the upper surface of the outer peripheral edge of the second dial plate 10 is the first opening in the first dial plate 6. The upper surface of the liquid crystal display unit 30 can be disposed close to the lower surface of the first dial plate 6 in contact with the lower surface of the inner peripheral edge of the portion 8a, whereby the second dial plate 10 is provided. In addition, the watch module 2 can be thinned.

  Further, in the timepiece module 2, the first dial 6 is provided with a first opening 35a to which the second dial 10 corresponds and a second opening 35b to which the liquid crystal display unit 30 corresponds. Therefore, the second dial plate 10 can be viewed from above the first dial plate 6 through the first opening 35a, and the time displayed on the liquid crystal display unit 30 through the second opening 35b. Information such as date and day of the week can be viewed from above the first dial 6.
