Abstract

PURPOSE:To announce the time to the user on the just hour and eliminate the user's inconvenience by letting buzzer sound be produced in a sounding member each time when a counter circuit counts pulses for 1 hour. CONSTITUTION:When the hands are set at 0 o'clock 0 minute 0 second and the circuit is started by depressing a winding crown 12, the counter 35 in an IC begins to count the pulse number having entered a motor 37 from zero in the reset state. When the counter 35 counts pulses of 3600, i.e., for 1 hour, sound is produced from a buzzer 19 corresponding to a sounding member 36. At this time, a switch SW-3 is ON and to prevent the alarm sound from being produced, SW-3, is turned OFF. The ON and OFF of SW-3 are made changeable by depressing a button 16. Displaying of whether alarming state or not is accomplished by letting a part of the movement being a display member appear in the hole 20a of a dial 20.
