Abstract

PURPOSE:To improve timepiece precision by controlling the frequency determining method of a quartz oscillator on the basis of fixed data. CONSTITUTION:The time reference signal of quartz oscillator 2 is frequency-divided 4 to drive 6 hand system time display unit 10. The frequency of oscillator 2 is determined by changing capacity values by switch 12, which is controlled in time zones appearing alternately in terms of time on the basis of manual setting code 34 and also controlled in time zones appearing alternately in terms of time on the basis of the output of temperature sense oscillator 22. In this case, a coincidence between the code output and frequency division output is detected 16 and a coincidence between temperature compensation data in ROM28 and the frequency division output is detected 16. Additionally, the control signal of switch control circuit 14 is output in response to the frequency division output and coincidence detection output.
