Abstract
An electronic timepiece and control method of an electronic timepiece prevent system shutdowns due to a voltage drop, and increase opportunities to acquire time information. An electronic timepiece 1 has a reception module 50 that receives satellite signals; a storage battery 24 that supplies drive power; a voltage detection circuit 74 that detects the voltage of the storage battery 24; a temperature detector 67 that detects temperature; a reception command unit that instructs receiving satellite signals; and a reception controller that executes a reception process to receive satellite signals in response to a command from the reception command unit. The reception controller executes the reception process when the detected battery voltage is greater than or equal to a threshold set for the detected temperature, and does not execute the reception process when the reserve power is less than the threshold.
