**Atomic Clocks: The Most Accurate Timekeepers in the World**

Atomic clocks are devices that use the frequency of atomic transitions to measure time. They were first developed in the 1950s and have since become the standard for international timekeeping. Atomic clocks are much more accurate than conventional clocks, as they can keep time with an uncertainty of less than one second in 100 million years.

One of the applications of atomic clocks is in wristwatches. Seiko, a Japanese company, has developed GPS-linked solar atomic wristwatches that can automatically adjust to the correct time zone by receiving signals from GPS satellites. These wristwatches are different from radio-controlled atomic wristwatches, which rely on radio signals from terrestrial atomic clocks. GPS-linked solar atomic wristwatches have the advantage of being able to work anywhere in the world, as long as there is a clear view of the sky.

However, even GPS-linked solar atomic wristwatches are not the most accurate timepieces in the world. That title belongs to chip-scale atomic clocks, which are miniature versions of atomic clocks that can fit on a single chip. Chip-scale atomic clocks have been developed by various research groups and companies, and they can achieve an accuracy of about one microsecond per year. Chip-scale atomic clocks have the potential to revolutionize many fields, such as navigation, communication, and cryptography.
