Abstract
An electronic timepiece wherein a quartz crystal oscillator produces a timekeeping standard signal which is divided by a transformer means formed of silicon gate complementary MOS transistor elements. The output of the transfer means is applied to a drive circuit which in turn is coupled to a digital display formed of liquid crystal elements. Time correction is performed by two switches, one switch selecting the digit of the display to be corrected, the other correcting the number displayed at the selected digit.
