Abstract: Power consumption due to failed automatic calibration is suppressed. An electronic watch is provided with a magnetic sensor, a processor for performing calibration of the magnetic sensor and controlling two or more function modes, and an acceleration sensor for sensing movement of a user. The processor determines whether a state of movement sensed by the acceleration sensor is a calibratable state in which calibration of the magnetic sensor can be performed, performs discrimination of a function mode being executed among the two or more function modes, and performs the calibration of the magnetic sensor when (i) the state of movement sensed by the acceleration sensor is the calibratable state and (ii) the function mode is not a non-default mode, the non-default mode being a function mode executed in accordance with an operation by the user.
