ABSTRACT:
An analog electronic watch of the present invention includes: a display unit (2) for displaying time with a position of a hand; a stepper motor (3) for driving the hand; a motor drive unit (4) for controlling driving of the stepper motor at a predetermined hand drive cycle at normal time; hand position detection means (5) for detecting a position of the hand; a hand position detection means control unit (6) for intermittently controlling driving of the hand position detection means (5) at a first detection cycle which is longer than the hand drive cycle; and a detection cycle changing unit (7) for instructing the hand position detection means (5) to change the detection cycle. When detecting a predetermined detection cycle changing condition, the detection cycle changing unit (7) changes a cycle at which the hand position detection means (5) detects a position of the hand, from the first detection cycle to a second detection cycle, while maintaining the hand drive cycle at which the stepper motor (3) drives the hand.
