ABSTRACT:
A timepiece having basic timepiece pointers, chronograph information pointers, a mechanical energy storage section, a train wheel, a power generator, and a control section. The basic timepiece pointers are rotated to indicate the standard time. The chronograph information pointers are rotated to indicate chronograph information. The mechanical energy storage section includes a mainspring. The train wheel is disposed between the mechanical energy storage section and the pointers, and transmits energy from the mechanical energy storage section to the pointers. The power generator has a rotating rotor connected to the train wheel, and generates electric power upon receiving the energy from the mechanical energy storage section. The control section is energized by the electric power produced by the power generator, and controls the rotation cycle of the rotor.
