Abstract

PURPOSE:To make electronic time corrections possible by making a second display by an optical display element by equipping 60 optical display elements around a minute display when an indication hand provides the display. CONSTITUTION:In normal operation, indication hand 30 makes the hour-minute display, and analog display part 23 composed of 60 optical display elements provided around the indication hand provides the second display. For time correction, a hour and minute are selected by selection switch S2 and a difference in time between a stop time and correction time is set to duodenary counter 45 and sexagesimal counter 53 by set switch S1. Then, when the contents of shift register 35 reach ''0, 0, 0, 1'', AND circuit 58 outputs a signal of 8Hz to let indication hand 30 make a rapid advance. At this time, the signal of 8Hz is supplied to sexagesimal counter 37 and duodenary counter 38 and when the contents of sexagesimal counter 53 agree with those of duodenary counter 47, the shift register is set to ''1, 0, 0, 0'' for a reset to a normal clocking operation.
