Early Bell Labs Crystal Oscillators

1927 to 1928

Crystal Oscillator - Quartz Clock

This modern clock uses an electronic oscillator controlled by a quartz crystal to keep time. Because of the very percise fequency of the crystal oscillator, these clocks are at least an order of magnitude more accurate than mechanical clocks.
