Abstract
Disclosed is an electronic timepiece, comprising: a second hand and a minute hand; a stepping motor which performs a stepping drive of the hands; a rotating body which includes a target section, and rotates with the second hand; a detection section which detects an existence of the target section; a detection control section which makes the detection section operate by every rotation period, to make the detection section detect the existence of the target section at a first timing and at a second timing; a hand position counter which counts estimated positions of the hands based on the number of drive times of the stepping motor; a counted value holding section capable of temporarily holding a value of the hand position counter; a counted value saving section which makes the counted value holding section hold the value; and a counted value correcting section which corrects the value.
