The first reliable electric clocks kept time with synchronous motors geared to the alternating-current cycles of electric power. They were replaced by quartz clocks that rely on the steady vibrations of a quartz crystal for higher accuracy. The next improvement was the 'atomic clock', which provides extremely accurate time by monitoring the electromagnetic radiation of cessium atoms, and synchronizes household 'atomic clocks' by radio transmission.
