摘要： An electronic alarm watch having an external operation device, which comprises a timekeeping section and an electronic calculator. The timekeeping section is composed of a quartz crystal oscillator connected to a first battery and providing a relatively high frequency signal to provide a low frequency signal, a counter circuit responsive to the low frequency signal to provide time information signals, a driver circuit providing driving signals in response to the time information signals, a time display section in response to the driving signals, an alarm time detection circuit connected to the counter circuit to detect an alarm time set by the external operation device, and an acoustic device responsive to an output from the alarm time detection circuit to generate a sound indicative of the alarm time. The electronic calculator is composed of a calculating section connected to the external operation device to perform calculation in response to input signals delivered from the external operation device, a calculator display section, and a booster circuit connected to second batteries to supply boosted output voltage to the calculating section and the calculator display section.
