PURPOSE: To enable optimum time indication according to conditions by providing a function of switching the contents of an analog indication section to the contents of a digital indication section.

CONSTITUTION: First and second time data separately outputted from first and second time counters 3 and 4 are supplied to an analog/digital indication decoder driver circuit 6 and a digital indication decoder driver circuit 7 through an analog/ digital indication switching circuit 5 to perform analog 8 and digital 9 indications. When an indication contents switch command is given with an external switch 11, the supply of the time data to the decoder drivers 6 and 7 is changed with an A/D control circuit 5 to vary the contents in the analog indication section 8 and the digital indication section 9.
