Abstract:
1. A timepiece comprising: basic timepiece pointers being configured to rotate to indicate the standard time; secondary time information pointers being configured to rotate to indicate secondary time information other than the standard time; a mechanical energy storage section being made of a mainspring; a train wheel being mounted between the mechanical energy storage section and the pointers to transmit energy from the mechanical energy storage section to the pointers, the train wheel being configured to be continuously rotated by the mechanical energy storage section, the train wheel having a reversing mechanism being configured to select whether the energy in the mechanical energy storage section is transmitted to the secondary time information pointers; a power generator having a rotor being arranged in the power generator and mechanically interlockingly connected to the train wheel to rotate, and to generate power upon receiving energy from the mechanical energy storage section; and a control section being configured to control the rotation cycle of the rotor, being energized and driven by the electric power produced by the power generator, control section being configured to control the rotation cycle by adjusting the brake torque applied to the rotor, and to control the direction in which the brake torque is reduced when the secondary time information pointers are being driven.
