An electronic timepiece comprising: a reception unit that is configured to lock onto a positioning information satellite and is configured to receive satellite signals from the locked positioning information satellite; a time adjustment unit that is configured to adjust internal time information based on the satellite signal received by the reception unit; a time display unit (22, 222) that is configured to display the internal time information; an illuminance detection unit that is configured to detect illuminance; and a reception control unit that is configured to control the reception unit, and includes an illuminance-based reception control unit that is configured to control the reception unit and to execute a satellite signal reception process when the illuminance detected by the illuminance detection unit equals or exceeds a specific illuminance threshold, and a scheduled reception control unit that is configured to control the reception unit and to execute a satellite signal reception process when the internal time information reaches a preset set time; wherein the illuminance-based reception control unit is configured to stop the reception process when a positioning information satellite cannot be locked onto within a first locking time when the reception unit is controlled and the reception process started, and the scheduled reception control unit is configured to stop the reception process when a positioning information satellite cannot be locked onto within a second locking time when the reception unit is controlled and the reception process started, characterized in that the second locking time is shorter than the first locking time, and in that the reception control unit is operable to select a first reception mode in which the illuminance-based reception control unit is operated and the scheduled reception control unit is stopped, and a second reception mode in which the illuminance-based reception control unit and the scheduled reception control unit are operated, wherein said reception control unit is further configured to switch control to the second reception mode when the reception process is not started within a specific time after starting control in the first reception mode, and is also further configured to stop the scheduled reception control unit when the reception process is started by the illuminance-based reception control unit after control is started in the second reception mode. a reception unit that is configured to lock onto a positioning information satellite and is configured to receive satellite signals from the locked positioning information satellite;
