ABSTRACT:
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; a manual reception process unit that starts operation of the reception unit and executes a manual reception process when an external operating member is operated; an automatic reception process unit that automatically operates the reception unit and executes an automatic reception process when a predetermined condition is satisfied; a simple time adjustment process unit that executes a simple time adjustment process to receive a satellite signal from one positioning information satellite by means of the reception unit, acquire time information from the received satellite signal, and adjust the internal time; and a high precision time adjustment process unit that executes a high precision time adjustment process to receive satellite signals from a plurality of positioning information satellites by means of the reception unit, acquire time information and positioning information from the received satellite signals and determine the location, and adjust the internal time to the time acquired based on the positioning result. The automatic reception process unit executes the simple time adjustment process by means of the simple time adjustment process unit when the automatic reception process executes, and the high precision time adjustment process unit executes the high precision time adjustment process only when the manual reception process is executed by the manual reception process unit.
