Abstract

PURPOSE:To enable an easy and rapid correction of a time, by a method wherein through pulling of a crown, a second hand is moved to a 12 o'clock position, and the second hand starts to move forward 1 second after it is pushed back. CONSTITUTION:With a crown pulled, a reset switch 8 is opened, in case a hand- moving pulse is not generated from a pulse generator 19 for moving a pulse, an output of an NAND gate 11 is produced into a low level, and an AND gate 12 is closed to bring a 1Hz output from a frequency divider 7 into a nullity. Meanwhile, an AND gate 16 or 17 is opened by means of a 29-omission 30-raised-to-unit signal outputted to a signal line 28 from a divide-by-60 system up-down counter 20, and a given dividing output from the frequency divider 7 is selected. Simultaneously, an output of an AND gate 27 is controlled, down and up counting of the counter 20 is controlled corresponding to backing and forwading, and a second hand spins counterclockwise or clockwise to a 12-o'clock position to stop thereat. With a switch 8 opened by depressing a crown by an announcement of time, a 1Hz pulse is brought into a valid state 1 second after a gate 12 is opened, the hand starts to move again, and this permits the rapid and easy correction of a time.
