Precise Time-Keeping: The Crystal Oscillator, the Atomic Clock…
The first atomic clocks were rather large and bulky, but in 2004 a chip-sized atomic clock was introduced. It was low-powered and compact enough to be operable on battery powered devices. Atomic clocks are used in a lot of time-sensitive application requiring high precision. For example, world time is kept by several atomic clocks …
Atomic Clock: The Atlas of Our Time
Using Cesium-133 atoms, scientists and engineers have implemented atomic clocks in a variety of experiments and systems. Since the 1960s, atomic clocks proved to be more precise than other timekeeping methods and being so, the second, the fundamental unit of time, was defined in terms of the atomic resonance of cesium-133.

Timekeeping and clocks FAQs | NIST
The benefits of an atomic clock are that the resonant frequencies are natural properties (not human-made) and that they are very high frequencies, in the billions of Hertz. If an atomic clock was off by 1 Hz and the frequency was 1 GHz (1 billion Hz), then it would be off by one second in 31.7 years or, roughly, 86 microseconds (0.000086 s) per ...

How Do Atomic Clocks Work?
Working Principle of Atomic Clocks. In an atomic clock, the natural oscillations of atoms act like the pendulum in a grandfather clock. However, atomic clocks are far more precise than conventional clocks because atomic oscillations have a much higher frequency and are much more stable. There are many different types of atomic clocks, but they ...
