An electronic timepiece includes a reception unit that receives satellite signals transmitted from positioning information satellites; a time information generating unit that generates an internal time; an automatic reception processing unit that activates the reception unit when predefined conditions are met to perform automatic reception processing, and performs simple time correction processing including acquiring time information from satellite signals received from one of the satellites, and, based thereon, correcting the internal time; and a manual reception processing unit that activates the reception unit via operation of an external member to perform manual reception processing, and performs simple time or high precision correction processing to correct the internal time, the high precision time correction processing including acquiring time and satellite orbit information from satellite signals received from two or more of the satellites, calculating a position of the timepiece, and correcting the internal time using the time information and the position. |
