Atomic Timekeeping

There is accuracy, and then there is accuracy measured in multiple millennia. The watches of the Citizen Atomic Timekeeping collection use radio controlled technology to synchronize with an atomic clock, for a margin of error of just one second in 100,000 years. Powered by Citizen’s visionary Eco-Drive movement that converts any kind of light into energy to power the watch, storing the surplus on a power cell, with no need for regular battery replacement.
