Abstract: An electronic timepiece includes a plurality of hands; a plurality of detection units that detect external light, arranged corresponding to the plurality of hands; and a control unit, wherein the control unit is configured to perform external light detection operations that respectively determine whether or not external light of a threshold value or more is detected at the plurality of detection units while moving the plurality of hands by a predetermined distance, respectively, and when there is a hand among the plurality of hands for which the external light detection operation detected external light and there is another hand among the plurality of hands for which the external light detection operation did not detect external light, perform the external light detection operation for said another hand again.
