Abstract
An analog electronic timepiece comprises a system control circuit for outputting a control signal to each operable circuit in response to a signal from an outer input switch, a chronograph storing circuit for storing the value a chronograph measuring means by a lap control signal outputted from the system control circuit, a lap time calculating circuit to which a measuring data of the chronograph measuring circuit and a former measuring data stored in the chronograph storing circuit by a former lap control signal are inputted for calculating the time difference between the above two data and outputting a correcting drive signal if the hand requires a correcting drive as a result of the above calculation and a drive judging circuit to which a lap input signal, an interruption signal, and a correcting drive signal outputted from the system control circuit are inputted for outputting a data of the drive number if the hand requires driving.
