PURPOSE:To correct a time difference in a circuit, by using an operating circuit to calculate the time difference in a region indicated by the second hand and rotating fast a motor on a basis of the calculated time difference. CONSTITUTION:A second hand 1 and a minute hand 2 are driven by independent motors, and an hour hand 3 is driven through a row of wheels by the minute hand 2. Each time a crown 7 is pushed, the display mode is switched to the home time mode and the world time mode. In the home time mode, the second hand 1 indicates seconds of the current time at every second. In the world time mode, the second hand 1 indicates the position of ante meridiem time or post meridiem time in a designated city name and is stopped. When the crown 7 is pushed in after the crown 7 is pushed up to correct the second hand 1 to a desired city, the hour hand and the minute hand are corrected to positions for the time in the designated city by fast-forwarding, and the second hand is corrected to indicate ante meridiem or post meridiem time. |
