Abstract
An electronic timepiece can adjust the input terminal and suppress power consumption. An electronic timepiece has: a reception unit 8 that receives a satellite signal containing time information from a positioning information satellite; a power supply unit 4 having a battery that supplies drive power; a remaining capacity detection unit 5 that measures the remaining battery capacity; and a control unit 9 that controls satellite signal reception by the reception unit 8. The control unit 9 includes a timekeeping unit 91 that keeps time, a time adjustment unit 99 that adjusts the time kept by the timekeeping unit 91 based on the satellite signal received by the reception unit 8, and a prohibition period setting unit 93 that sets a prohibition period in which receiving a satellite signal is prohibited based on the remaining battery capacity measured by the remaining capacity detection unit 5.
