Abstract
An electronic battery-powered watch including an oscillator followed by a chain of frequency divider stages, said chain being composed of two parts with an interface circuit between said two parts, said interface circuit multiplying by a predetermined amount the voltage of the battery and the amplitude of the pulses issued from the last stage of the first part of the division chain in order to feed and control the second part of the chain and the decoding and display circuits of the watch.
