PROBLEM TO BE SOLVED: To make actual winding-up of a power spring correspond to the degree of winding of the power spring of an indicating hand without causing a difference. SOLUTION: The stored power display device mechanism is used for the movement of a time piece of the type that has a power source by means of the power spring. This mechanism has a frame, the stored power indicating hand, and a differential gear 30. The differential gear has a first input part connected with a gear rotated and driven when the power spring is wound, a second input part connected with a gear rotated and drive when the power spring is loosened, and an out part 36a connected with the indicating hand. The indicating hand can show a position of an arbitrary angle between two terminal position.
