PURPOSE:To manufacture a high accuracy timepiece having durability extending over a long period of time, by providing a mechanical energy accumulating device and a mechanical vibrator driven by supplying energy from this accumulating device. CONSTITUTION:A titled timepiece has a mechanical energy accumulating device 9, and a transmitting system 10 and a governing system 11 of mechanical energy. Also, it is provided with a power generating device 12 for converting the mechanical energy of this governing system 11 to electric energy, an electronic crystal oscillator 13 to which energy is supplied from the power generating device, and an electronic circuit 14 by which an oscillating signal of the crystal oscillator becomes a source signal. Moreover, it has a control device 17 of a governing device of 12 for obtaining an output from power lines 15, 16 and the electronic circuit 14 outputted by the power generating device. The control device is a mechanical force transducer of electric energy, and a device for electromagnetic conversion, piezoelectric conversion, electrostatic conversion, etc. |
