What is Eco Drive technology?

One of Citizen's challenges: developing a technology that would ensure the watch would continue to run, anywhere in the world. In 1976, they invented the first light-powered analog quartz watch that runs exclusively on light. This technology, now known as Eco-Drive, can generate energy from any light source (artificial light, natural light, and even dim light) to keep watches running without ever needing to be replaced.

What is Radio Controlled Technology?

The radio-controlled system installed on the watch receives the time signal generated by an atomic clock transmitted via radio waves. The atomic clock and every Citizen radio-controlled watch are absolutely precise, with a tolerance of 1 second every 10 million years. To avoid interference with smartphones and other devices used throughout our busy days, Citizen radio-controlled watches receive radio signals late at night to adjust the time and date.
