Abstract

PURPOSE:To perform correction to obtain local time simultaneously in the case the time in each time zone of the world is displayed on a map, by specifying the gear ratio of train wheels which correct a display plate of 24-hour indication and an hour hand of 12-hour indication at the same time. CONSTITUTION:A winding stem 13 supported by a main plate 25 is pulled by one step. Then a setting wheel 16 provided on a rocking bar 15 is moved to a position (arrow A), where it is engaged with intermediate wheels 17 and 18 which are in turn engaged with gears 3 and 4, by a setting mechanism comprising a pin 14a provided in a setting lever 14 and an irregular groove 15a of the rocking bar 15. When a world map whose center is the north pole is displayed in the display plate 8. The gear ratio between the gear 3 and the intermediate wheel 17 and the gear ratio between the gear 4 and the intermediate wheel 18 are set as 1:1.5. Then the hour hand 9 and the display plate 8 are rotated at a speed ratio of 1:1.5. By providing a time differential correcting means, each local time can be readily read out. Under the normal hand operating state with the winding stem 13 being pushed, the setting wheel 16 selects the intermediate position between the arrows A and B, and the hour hand 9 and the display plate 8 are driven at the same speed.
