News on January 26th. At present, the common atomic watches on the market are generally synchronized with the international atomic clock through wireless signals to reduce time errors. And I found the most punctual “watch” in the world on a strange website called leapsecond.

A user posted that his brother-in-law Bill created the world’s first atomic clock watch, which is composed of an HP5071A cesium atomic clock and two “straps”.

The watch has an error of a few nanoseconds per day, is equipped with a 7-segment red LED screen, the battery can provide 45 minutes of battery life, and an AC charger is included.
