Abstract

PURPOSE: To increase the accuracy of the ring time by securing the synchronization between the analog hands and the time counter when the hand setting is given for the analog-type watch and then giving the alarm tone via the time counter.
CONSTITUTION: With pull-out of crown 57, hand time detection synchronous means 58 operates, and time counter 60 is set to the same time of the hands through switch circuit 59. The alarm time is memorized in time memory circuit 62 with operation of selection and set buttons 24 and 25 each. The time memorized in circuit 26 is compared with the present time at sequence detection circuit 70, and then the memory circuit featuring the minimum time gifure is detected to be displayed 14 through decoder 64 as well as to be used as the comparison signal to be applied to coincidence circuit 63. Accordingly, when the coincidence is secured with the count value of time counter 60, alarm 67 is driven. At the same time, display mark 18 for the daytime and night is lit up by the hour digit of circuit 62.
