Abstract

PURPOSE:To achieve a quick time setting by separately operating time indication units at the quick shift driving with the driving and transmission made independent of each other for each indication unit. CONSTITUTION:A second hand driving stepping motor 1 runs once per 1sec to shift a second hand 8 by one gradation. A minute hand driving stepping motor 9 runs once per 1 minute to shift a minute hand 17 by one gradation per 1 minute. An hour hand 23 is turned with an hour shaft 22 through a gear 18 from a pinion 16. To shift the second hand 8 or the minute hand 17, the second hand driving stepping motor 1 or the minute hand driving stepping motor 9 is rotated quickly by operating a second quick shift switch or a minute quick shift switch.
