An electronic watch includes a pointer; a stepping motor including a coil and configured to drive the pointer; a driving circuit configured to drive the stepping motor; an A/D converter configured to detect electromotive force generated in the coil due to an impact; and a CPU configured to control driving of the driving circuit. The CPU determines a direction in which the pointer is likely to be shifted, based on the electromotive force detected by the A/D converter, determines whether the pointer is shifted due to the impact, and upon determining that the pointer is shifted, corrects a position of the pointer in accordance with the direction in which the pointer is likely to be shifted.
