In an electronic timepiece having a quartz crystal controlled standard frequency oscillator and a device which temporarily imposes a heavy load on the battery when activated, means are provided for changing a value of a circuit constant in the oscillator circuit, such as capacitance or resistance, when the load device is activated. This change in circuit constant value serves to decrease the value of the minimum battery supply voltage below which the oscillator circuit ceases to function, thereby ensuring reliable operation of the oscillator circuit when the timepiece battery voltage drops due to current being supplied to the load device.
