  Thus, according to this wristwatch, the train wheel block 6 having the chronograph function is composed of a plurality of train wheels, that is, a three-needle train wheel 15, a two-needle train wheel 16, a second hand train wheel train 17, and a date wheel. With the configuration in which the train wheel trains 18 are arranged in a planar manner, the thickness of the train wheel block 6 can be reduced, and a plurality of train wheel trains can be assembled in a planar manner, so that the assembly workability is good. . In addition, since the circuit board 7 is arranged on the lower side of the train wheel block 6 in which a plurality of wheel trains are assembled in a plane, the circuit board 7 does not need to be divided into a plurality of parts, and one circuit board 7 is attached to the wheel block. It can be easily overlapped and assembled to the row block 6, and the assembly workability can also be improved. Further, since the antenna 8 and the battery 9 are respectively disposed on the side portions of the train wheel block 6 and the circuit board 7 within the thickness range in which the train wheel block 6 and the circuit board 7 are overlapped, Even if the battery 9 is thick, the antenna 8 and the battery 9 can be incorporated in a compact manner. As a result, the entire watch can be made thinner.

  In this case, the train wheel block 6 includes a three-needle train wheel 15 in which three hands of the second hand 15a, the minute hand 15b, and the hour hand 15c are arranged on the same axis and moved by the first and second pulse motors 21 and 22, and the minute hand. 16a and an hour hand 16b are arranged on the same axis, and a two-needle train wheel 16 that is moved by the third pulse motor 23, and a second hand dedicated train wheel 17 that moves only the second hand 17a by the fourth pulse motor 24; By including a date wheel train 18 for rotating the date wheel 26 by the fifth pulse motor 25, a 3-needle train wheel 15, a 2-needle train wheel 16, a second hand train wheel 17, and a date The vehicle wheel train 18 can be driven independently, whereby any one of the train trains 15 to 18 can be changed between the time system and the chronograph system, and the time system and the chronograph system Can be freely changed and combined, this More time system and in addition to variations of a combination of a chronograph system become rich, it is more of a multi-function display.

  For example, as in the above-described embodiment, the second pulse motor 22 that moves the minute hand 15b of the three-needle train wheel 15, the hour hand 15c, the fourth pulse motor 24 that moves the second hand 17a of the second-hand wheel train 17, and The fifth pulse motor 25 that moves the date wheel 26 of the date wheel train 18 is driven as a time system, and the first pulse motor 21 that drives the second hand 15a of the 3-needle train wheel 15 and the second train wheel 16 of the needle train 16 are driven. The third pulse motor 23 for moving the minute hand 16a and the hour hand 16b, and the fourth pulse motor 24 for moving the second hand 17a of the second hand wheel train 17 can be driven as a chronograph system.

  Further, the first and second pulse motors 21 and 22 for moving the second hand 15a, the minute hand 15b, the hour hand 15c and the 24 hour hand 15d of the three-wheel train wheel 15 and the date wheel 26 of the date wheel train 18 are moved. A third pulse motor 23 that drives the five-pulse motor 25 as a time system and moves the minute hand 16a and hour hand 16b of the two-needle train wheel 16, and a fourth pulse motor 24 that moves the second hand 17a of the second-hand wheel train 17; Can also be driven as a chronograph system. Further, by driving the pulse motors 21 to 25 in combinations other than these, the time system and the chronograph system can be appropriately changed, and more multifunctional displays such as world time can be performed.

  Further, in this wristwatch, the 3-needle wheel train 15, the 2-needle train wheel 16, the second hand train wheel train 17, and the date wheel train train 17 are assembled to the main plate 19 and the train wheel bridge 20. The three-needle train wheel 15, the two-needle train wheel 16, the second hand train wheel train 17, and the date wheel train train 18 can all be assembled to the main plate 19 and the train wheel bridge 20 in a substantially planar manner. Since the three-needle train wheel 15, the two-needle train wheel 16, the second hand train wheel train 17, and the date wheel train train 18 operate independently, the three-needle train wheel 15, two-needle train wheel The wheel train 16, the second hand wheel train 17, and the date wheel train 18 can be individually incorporated, thereby further improving assembling workability.

  In this case, the date wheel 26 of the date wheel train 18 is arranged on the surface side along the outer peripheral portion of the main plate 19, and a part of the antenna 8, a part of the battery 9, and a part of the date wheel 26. Are overlapped at different positions in the plane direction, so that even if a part of the antenna 8 and a part of the battery 9 are overlapped at different positions in the plane direction on the date wheel 26 of the date wheel train 18 Among the blocks 6, the location of the date wheel 26 of the date wheel train 18 is the thinnest, so that the thickness of the watch module 3 is hardly increased, and the antenna 8 and the battery 9 can be incorporated in a compact manner. This also makes it possible to reduce the size of the entire watch.

  In particular, the 24-hour hand wheel 37 and the gear train 41 of the three-needle wheel train 15 are arranged on the surface side of the main plate 19, so that the locations of the 24-hour hand wheel 37 and the gear train 41 of the three-needle wheel train 15 are reduced. Since the thickness of the battery 9 can be reduced and a part of the battery 9 overlaps the 24-hour hand wheel 37 and the gear train 41, the thickness of the timepiece module 3 is hardly increased, and the battery 9 is made compact. It can be incorporated, and this can also reduce the overall size of the watch.

  Further, in this wristwatch, an intermediate receiver 38 for supporting a fourth wheel 31 which is a second hand wheel of the three-needle wheel train 15 is arranged between the main plate 19 and the train wheel receiver 20.
