Quartz controlled chronometer

Claim 1

A timepiece having time indicating means comprising: a quartz crystal oscillator having a high frequency output, a frequency divider for reducing the output of the quartz oscillator to a low frequency, a polarity changing driver connected to the divider for changing the polarity of the driving current after each driving impulse, the polarity changing driver comprising a first input line and a second input line, a first plurality of transistors coupled to the first input line such that rising potential on said first input line saturates said first plurality of transistors, a second plurality of transistors coupled to said second input line such that ground potential on the second input line cuts off said second plurality of transistors while the first plurality of transistors are saturated, and means coupled to each input line for producing a predetermined output pulse upon receipt of an input from the divider, and wherein, the means for producing a predetermined out-put pulse comprises a resistor-capacitor network connected across the first and second input lines, and, each plurality of transistors comprises a first transistor having its base connected to a particular input line and second and third transistors, the base of the second transistor being connected to the collector of the first transistor and the base of the third transistor being connected to the emitter of the first transistor.
