摘要：An electronic timepiece efficiently acquires leap second information, reducespower consumption, and enables displaying the correct time. A GPS wristwatch has asatellite signal reception unit A that receives satellite signals, a power supply including a

solar panel and storage battery , a time information adjustment unit that keeps time, areception timing determination unit that operates the satellite signal reception unit A,receives a satellite signal, and acquires leap second information contained in the satellitesignal, and a reception determination unit that detects the remaining capacity of thestorage battery . When the remaining battery capacity measured by the receptiondetermination unit is greater than or equal to a specific value, the reception timingdetermination unit sets the reception frequency for receiving a satellite signal higherthan when the remaining battery capacity is less than the specific value.
