What is Eco Drive technology?

One of Citizen's challenges: to develop a technology that would guarantee the constant functioning of the watch, anywhere in the world. In 1976, they invented the first light-powered analog quartz watch that works using only light as an energy source. This technology, now known as Eco-Drive, can generate the energy from any light source—artificial light, natural light, and even dim light—to keep the watches running without ever replacing the battery.

What is Radio Controlled Technology?

The radio control system installed on the clock receives the time signal generated by an atomic clock transmitted by means of radio waves. The accuracy of the atomic clock and of each Citizen radio-controlled watch is absolute, with a tolerance of 1 sec every 10 million years. To avoid interference with smartphones and other devices used during our busy days, Citizen radio-controlled watches receive radio signals late at night to adjust the time and date.
