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 operates using only light as a power source. 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 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 radio controlled Citizen clock is absolute, with a tolerance of 1 second every 10 million years. To avoid interference with smartphones and other devices used during our busy days, radio-controlled Citizen watches receive radio signals late at night to adjust the time and date.
