Abstract

PURPOSE: To make the pace measurement of a variable division type electronic watch possible by outputting electric signals of frequency data of a reference oscillator and set-value data of a variable division ratio.
CONSTITUTION: When a pace measurement mode is set by holding mode switch 20 at logic "0", variable division operation stops by gate 21. Simultaneously, a conditional terminal in a set state of a varialbe division ratio circuit among respective gates constituting set-signal generating circuit 9, e.g. gate 13 connected S3 turns ON to supply signal F3 to terminal D of display driver circuit 5. In this state, the waveform of signal F3 is detected by a detection microphone to measure the period, and consequently frequency accuracy when no variable division is done by reference oscillator 1 can be found while the set value of the division ratio can also be obtained from the frequency. Therefore, the pace of the variable division type electronic watch can be measured from two measured values.
