Abstract:
1. An analog electronic watch including: a display device for displaying time with a position of a hand being driven; a hand drive device for driving the hand; a hand drive device control unit for controlling driving of the hand drive device at a predetermined hand drive cycle in a normal state; a hand position detection device for detecting a position of the hand; and a hand position detection device control unit for intermittently controlling driving of the hand position detection device at a first detection cycle longer than the hand drive cycle, the analog electronic watch comprising a detection cycle changing device for instructing the hand position detection device control unit to change a detection cycle of the hand position detection device, wherein upon detection of a predetermined detection cycle changing condition, the detection cycle changing device changes a cycle at which the hand position detection device detects a position of the hand, from the first detection cycle to a second detection cycle, while maintaining the hand drive cycle in which the hand drive device drives the hand.
