Frequency adjustment means for an electronic timepiece

摘要

An electronic horological instrument which includes a piezoelectric crystal oscillator and a counter such as a series of count-down circuits connected in tandem. The "effective frequency of the oscillator" is adjusted by inhibiting the oscillator pulses to the count-down circuits by means of a pulse inhibit circuit. The pulse inhibit circuit is readily programable to inhibit a desired number of oscillator pulses by means of a switch arrangement that includes multi-position detented pin switches.
