ABSTRACT:
An electronic timepiece wherein the timekeeping circuitry is formed of bipolar transistors and C-MOS transistors integrated on a single integrated circuit chip substrate is provided. The electronic timepiece includes timekeeping circuitry for producing timekeeping signals and a display device for displaying time in response to the timekeeping signals. At least a portion of the timekeeping circuitry is formed of C-MOS transistors formed on an integrated circuit chip substrate, a further portion of the timekeeping circuitry being formed of bipolar transistors formed in the same integrated circuit chip substrate as the C-MOS transistors.
