    摘要: The invention relates to a timepiece device (1), in particular for a vehicle, comprising a control unit (2) for time keeping, which is synchronizable by a clock generator. Thereby the timepiece device (1) having at least two crystal oscillators built respectively by at least one crystal unit (3.1, 3.2), whereby a first crystal oscillator with a first crystal unit (3.1) and with a predetermined nominal oscillation frequency is suitable for use as the clock generator of the control unit (2) during a vehicle standby mode, and whereby the oscillation frequency of the first crystal oscillator is at least temporarily measured and adjustable by a second crystal oscillator with a second crystal unit (3.2) whose nominal oscillation frequency is higher than that of the first crystal oscillator.
    Further the invention relates to a method of operation of the timepiece device (1), whereby the oscillation frequency of the second crystal oscillator is compensated against the temperature by the software inside the control unit (2).
