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.
