Abstract:
An electronic timepiece includes a reception unit that receives satellite signals from positioning information satellites; a time information generating unit that generates an internal time; and a manual reception processing unit that activates the reception unit through operation of an operating member and executes a first or a second time correction processing to correct the internal time. The first time correction processing includes acquiring time information from a satellite signal received from one of the positioning information satellites and correcting the internal time based thereon. The second time correction processing includes acquiring time information and satellite orbit information from satellite signals from one or more of the positioning information satellites, calculating the position of the electronic timepiece, and correcting the internal time using the acquired time information and the calculated position. The selection of the first or second time correction processing is based on manual operation.
