摘要： A quartz crystal timepiece incorporating a vibrator unit is disclosed. The vibrator unit is hermetically sealed in a case on which a condenser is fixed and the condenser compensates the oscillating frequency of said vibrator unit to a predetermined center frequency by suitably selecting the capacitance of the condenser after measuring the natural frequency of the vibrator unit. Then there is no need to adjust each vibrator unit to the predetermined center frequency during assembling process.
