Abstract

PURPOSE:To realize a long life time of the battery for the watch which is capable of performing several time displays, by stopping temporarily the supply of the power or the driving pulse to the unnecessary display part. CONSTITUTION:The power is supplied to motor 10 performing the analog display, wheel train 12 and others from battery 14. At the same time, the power is supplied to the decoder performing the digital display, driver 18 and display 20 via switching circuit 22. When the display is not necessary at part 20, circuit 22 is cut off. Thus the power supply is stopped to the decoder, driver circuit 18 and part 20 each.
