The utility model relates to a novel high-precision quartz clock which mainly comprises a clock chip, a CMOS integrated circuit, a stepper motor, a gear driving system, a pointer, a clock casing, a power supply and the like, wherein the CMOS integrated circuit consist of an oscillating circuit, a fractional frequency circuit and a driving circuit. As the clock chip is a real time clock chip and is characterized by high precision, stable and reliable work, simple periphery interface and the like, the clock chip is widely applied to various occasions needing higher precision real time clocks; the precision of the quartz clock time base is guaranteed by using the clock chip with the precise time source as the precise time source of the quartz clock. By testing, the travel time accuracy of the quartz clock adopting the clock chip is greatly increased, the error of the clock in a month is less than one second, therefore, the precise travel time of the quartz clock is realized and the quartz clock is an ideal timing device in daily work and life.
