Electronic timepiece

Abstract

An electronic timepiece comprising a fundamental frequency oscillator, a plurality of frequency divider stages, a timekeeping mechanism and display, includes circuitry for resetting and setting selective stages of the divider and thereby adding or subtracting timing pulses which are delivered to the timekeeping mechanism. A non-volatile memory stores data which terminates whether a divider stage is to be set or reset. Additionally, a plurality of circuit elements are selectively inserted to modify the circuit of the oscillator and to provide frequency adjustment. External contacts are provided for the inputting of data to memory and for measuring timing rate against an external standard.
