Abstract
Abstract A power supply for a watch including voltage multiplying means or transforming means to increase the voltage of a power cell to a higher voltage capable of operating electrical and electronic devices used in watches requiring voltage higher than the conventional 1.5 volts. These include highly efficient quartz oscillators and dividing units, MOS integrated circuits, solid state indicating systems, crystals, piezoelectrical and electrostatic motors and piezoelectric alarm systems, and associated systems. A DC-AC converter or chopper is connected respectively to a voltage multiplier or transformer and the high voltage output therefrom is suitable for driving various types AC or DC systems used in watches. The use of a plurality of batteries or other undesirable structures is thereby avoided.
