Abstract

An electronic timepiece efficiently acquires leap second information, reduces power consumption, and enables displaying the correct time. A GPS wristwatch 1 has a satellite signal reception unit 10A that receives satellite signals, a power supply including a solar panel 70 and storage battery 60, a time information adjustment unit 25 that keeps time, a reception timing determination unlit 24 that operates the satellite signal reception unit 10A, receives a satellite signal, and acquires leap second information contained in the satellite signal, and a reception determination unit 23 that detects the remaining capacity of the storage battery 60. When the remaining battery capacity measured by the reception determination unit 23 is greater than or equal to a specific value, the reception timing determination unit 24 sets the reception frequency for receiving a satellite signal higher than when the remaining battery capacity is less than the specific value.
