As shown in FIG. 2, the intermediate wheels 44 are positioned symmetrically, and each is held in mesh with two 24-hour wheels 45. The 24-hour wheels 45 are also positioned symmetricall,y as shown in FIG. 2.
  • each 24-hour gear 45 makes one rotation.
  • the hour hand 12 of the main timepiece 10 is mounted on the barrel wheel 42 and makes one turn for 12 hours, as stated earlier.
  • each 24-hour wheel 45 makes one rotation for two rotations of the barrel gear 42, i.e., for 24 hours.
  • a back plate 50 is affixed to the time display side of a base plate 46 by screws 48.
  • the screws 48 are so shaped and dimensioned as not to protrude from the back plate 50 at the time display side.
  • Three round holes 52 are formed in the back plate 50 at symmetrical positions which are spaced a predetermined distance from the center of the timepiece.
  • six round holes 54 are formed in the back plate 50 at symmetrical positions radially outwardly of the holes 52 and spaced a predetermined distance from the center of the timepiece.
  • Each intermediate gear 44 has a shaft 44A rotatably received in the respective hole 52.
  • each 24-hour wheel 45 has a shaft 45A rotatably received in the respective hole 54.
  • a dial plate 56 is provided on the time display side of the intermediate wheels 44 and 24-hour wheels 45. Provided on the dial plate 56 are the previously mentioned 12-hour dial 18 of the main time piece 10 and the 24-hour dials and numerals of the auxiliary timepieces 20 ⁇ 30. The dial plate 56 is supported by a support ring 58.
  • a pin 458 is studded on the center of each 24-hour wheel 45 in such a manner as to protrude from the dial plate 56 at the time display side.
  • the hour hand 32 of each of the auxiliary wheels 20 ⁇ 30 is mounted on the tip of the respective pin 45B. Because the 24-hour wheels 45 rotate in the same direction as the barrel gear 42, as stated previously, the hour hand 12 of the main timepiece 10 and the hour hands 32 of the auxiliary timepieces 20 ⁇ 30 turn in the same direction as each other.
  • a machine body 62 including a battery and a motor, is interposed between the base plate 46 and a rear cover 60 in order to drive the barrel wheel 42 as well as the other components.
  • a crown 64 is located at the right-hand side, as viewed in FIG. 3.
  • the place name ring 34 can be turned relative to a case 66 by hand.
  • the dial plate 56 and a crystal 68 define a space therebetween.
  • the hour hands 32 of the auxiliary timepieces 20 ⁇ 30 and the hour hand 12, minute hand 14 and second hand 16 of the main timepiece 10 are turnable in the space between the dial plate 56 and the crystal 68 at respective levels which sequentially increase in this order.
  • the auxiliary timepieces 20 ⁇ 30 will be described more specifically with reference also made to FIG. 1.
  • the six timepieces 20 ⁇ 30 are respectively aligned with the 12.00, 2.00, 4.00, 6.00, 8.00 and 10.00 positions of the timepiece 10, as stated earlier. All the timepieces 20 ⁇ 30 display times on a 24-hour basis. Nearby ones of the hour hands 32 have a time difference of 4 hours.
  • the hour hand 32 of the timepiece 22 indicates a time 4 hours ahead of the hour hand 32 of the timepiece 20.
  • the hour hand 32 of the timepiece 24 indicates a time 4 hours ahead of the hour hand 32 of the timepiece 22.
  • the place name ring 34 has a circumference representative of 24 hours.
  • the hour hands 32 of the auxiliary timepieces 20 ⁇ 30 are conditioned such that, among the 24 hours on the ring 34, six different times sequentially incremented (or decremented) by each 4 hours are indicated by the timepiece 20 ⁇ 30.
  • the main timepiece 10 operates in the same manner as a conventional timepiece. Specifically, a driving force from the machine body 62 is transmitted to the hour hand 12, minute hand 14 and second hand 16, causing the timepiece 10 to display a time.
  • the auxiliary timepieces 20 ⁇ 30 are interlocked with the main timepiece 10. Hence, only if the timepiece 10 is set, the timepieces 20 ⁇ 30 are automatically set to the times sequentially incremented by each 4 hours due to the operation of the barrel gear 42, second intermediate wheels 44, and 24-hour wheels 42.
  • auxiliary timepieces 20 ⁇ 30 indicate times different from each other by 4 hours, and the timepiece 20 is coincident with the main timepiece 10 as to time. The timepieces 20 ⁇ 30, therefore, display times ahead of the time of the main timepiece 10 by each 4 hours.
  • the user of the timepiece turns the place name ring 34 until the place name associated with the time of the main timepiece 10 has been aligned with the auxiliary timepiece 20.
  • the mark " TOKYO" on the ring 34 is aligned with the timepiece 20.
  • the user can see the times of the places whose times are 4 hours, 8 hours, 12 hours, 16 hours and 20 hours ahead of Tokyo time (or 20 hours, 16 hours, 12 hours, 8 hours and 4 hours past of Tokyo time) on a real time basis.
  • the user should only read the time of the timepiece 28 with which the marks " PARIS" and " ROME" are aligned.
  • FIG. 5 shows how the hour hands of the main timepiece 10 and auxiliary timepieces 20 ⁇ 30 sequentially move.
  • the hour hands each sequentially moves as shown in (A) , (B), (C) , and (D) in this order.
  • the six hour hands move in an extremely interesting way as the time elapses.
  • the present invention is not limited to the embodiment described above, but it also includes the following embodiments.
  • the auxiliary timepieces indicative of the times of various places are arranged on a circle representative of 24 hours.
  • the times indicated by nearby auxiliary timepieces have a difference corresponding to the distance between the auxiliary timepieces on the circle.
  • the names of places are provided, in consideration of the time differences, on the place name ring whose circumference corresponds to 24 hours. This allows the times of various places to be easily read.
  • the auxiliary timepieces are automatically set. Once the place name ring is set, the times of various places can be read on a real time basis without resorting to any additional operation. The operation is, therefore, extremely easy.
  • the hour hands of the auxiliary timepieces move every moment, implementing interesting time display.
