Abstract

PURPOSE: To facilitate the enhancement of the accuracy of an electronic wrist watch and the reduction in its size and thickness, by providing a logical means or changing additional capacitances to speed up or down the time reference oscillator of the watch, which employs a constantly elastic meterial.
CONSTITUTION: The additional capacitances 3a, 3b of an oscillation unit 2a including the time reference oscillator 1 employing the constantly elastic material are changed or a switch 4a for altering the frequency division ratio of a frequency divider 4 is operated to produce an output 5 of desired frequency. The frequency of the oscillator is adjusted without deteriorating its proper frequency-temperature characteristic. This results in facilitating the enhancement of the accuracy of the watch and the reduction in its size and thickness.
