示形電子時計。 A display control circuit unit that includes a digital counter that counts second pulses from a frequency dividing circuit and outputs time information, an optical display unit that displays digital time information, and a storage unit that includes a hand position counter that counts hand positions. , a pointer that displays analog time information, and an arithmetic circuit section that includes a coincidence detection circuit that synchronizes the digital counter and the hand position counter, in which a drop in power supply voltage is measured. a control means for correcting at least the pointer to a predetermined reference position based on an output signal from the measurement circuit; and a control means for detecting that the power supply voltage has exceeded a reference value and outputting the result. and a power-on detection circuit that emits a signal, and when the power supply voltage exceeds a reference value, the output signal of the power-on detection circuit moves the digital counter and the needle position counter to the reference position of the pointer. 1. A composite display electronic timepiece characterized in that an analog display section and a digital display section are synchronized to the same reference time by resetting to corresponding contents.
