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.
