In a crystal oscillator for solid state wristwatches, the input of an impedance converter is connected to the output of a complementarily connected transistor amplifier which performs linear operation within its essential operating range, thereby stabilizing and decreasing output impedance of the amplifier on the average. The impedance converter includes one or more active elements such as MOSFET's, junction type FET's and bipolar transistors. A quartz oscillator is connected between the input of the complementarily connected transistor amplifier and the output of the output impedance converter.
