Abstract

PURPOSE: To set the time to be corrected arbitrarily to the time precision peculair to a particular watch, by storing the time to correct the wave and the interval thereof in an internal memory.
CONSTITUTION: In a crystal wristwatch with digital type permanent calender having wave time correction function, a CPU 10 providing all controls of the watch is furnished with an unlock terminal 11, a mode select terminal 12, a select terminal 13, and a set terminal 14. Under unlocked state, the wave correction mode is called by the mode select terminal 12, and the time and time interval for wave correction is successively set by the select terminal 13 and set terminal 14. The time standard wave entering from an antenna 18 is discriminated in a standard time signal wave discriminating circuit 21, so that a second counter 4 being placed in the reset state is started at the just time.
