Q. Is quartz a good clock?

Quartz clocks are more accurate than the greatest mechanical ones. The device utilizes a quartz crystal with a precise cutting that resonates at a predetermined frequency when an electric current is passed through it. In an electrical circuit the vibrations can be maintained indefinitely producing a signal with a constant frequency that can be used to keep time. Quartz watches and clocks are electronic timepieces that utilise an oscillator controlled by a quartz crystal. With the help of this crystal oscillator quartz clocks and timepieces are at least ten times more exact than their mechanical counterparts.
