Abstract

PURPOSE: To achieve accuracy of alarm sounding time of a hands display watch, by setting the counter to generate alarm timing signal at every specified time by maching with the display of hands.
CONSTITUTION: When a set signal is applied to a terminal 7 by external operation at the moment the hand reaches 5, 10 or 15 minutes according to the set unit of the alarm time such as 5 minutes, 10 minutes, and 15 minutes, a unit counter 18 is reset, and the counting is started immediately, so that the alarm timing signal may be generated at every 5, 10, or 15 minutes. Thereby, at every specified time, FF 19 is set, and an AND gate 23 is opened by the set output of FF 19. At the time of opening of this gate 23, the protrusion of an unlocking wheel 2 and the hole in an hour wheel 1 are engaged, and the set output of FF 22 of which switch 4 is closed triggers an alarm driving circuit 13, so that the alarm sound is correctly emitted when the hands indicate the alarm time which has been set according to the set unit time.
