Abstract

PURPOSE:To reduce the number of circuit elements needed in an electronic timepiece having analog and digital display units by using only the digital display unit to display the warning of running out of the cell power. CONSTITUTION:By the signal of 1Hz which has been divided down 12, time is displayed on an analog display unit 15 and a digital display unit 18. At the falling of the 1Hz signal, a stepper motor 13 is driven, and at the rising of the 1Hz signal, the cell voltage is detected 19. When the cell voltage has lowered below a given value, a display controller 17 turns the digital display unit 18 on and off.
