Abstract

An electronic timepiece includes a detection axis calibration unit configured to execute first calibration processing of calibrating an axial direction and second calibration processing of calibrating a direction along a third detection axis, the second calibrating processing being executed after first calibration processing, a mode setting unit configured to set a first measurement mode when second calibration processing is not completed after completion of the first calibration processing, and set a second measurement mode when the second calibration processing is completed, a first azimuth calculation unit configured to calculate an azimuth, based on detected values of a three-axis magnetic sensor in two axial directions, when the first measurement mode is set, and a second azimuth calculation unit configured to calculate an azimuth, based on detected values of the three-axis magnetic sensor in three axial directions and a detected value of a inclination sensor, when the second measurement mode is set.
