What is Eco Drive technology?

One of Citizen's challenges: to develop a technology that would ensure that the watch would always work, anywhere in the world. In 1976, they invented the first light-powered analog quartz watch that works using only light as a source of energy. 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 watch receives the time signal generated by an atomic clock transmitted by radio waves. The precision of the atomic clock and of every 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 set the time and date.
