An electronic timepiece includes a reception unit that receives satellite signals transmitted from positioning information satellites; 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 such a process to receive a satellite signal from one positioning information satellite, acquire time information from the received satellite signal, and adjust an internal time; and a high precision time adjustment process unit that executes such a process to receive satellite signals from a plurality of positioning information satellites, acquire time 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 simple time adjustment process is executed when the automatic reception process executes. The high precision time adjustment process is executed when the manual reception process executes, after voltage detection of the battery is detected and if the so detected voltage is greater than a prescribed voltage. |
