Citizen Eco-Drive watches are powered by light, converting both natural and artificial light sources into energy. This energy is then stored in a special power cell, allowing the watch to function without regular battery replacements. A fully charged Eco-Drive can run for months, even in total darkness.
Eliminating the need for battery changes contributes significantly to environmental sustainability by reducing battery waste. This feature also offers unparalleled convenience for the wearer, as it removes the hassle and expense of periodic replacements. Eco-Drive technology, first introduced by Citizen in the 1970s, has continuously evolved, demonstrating a long-standing commitment to innovation and practicality in watchmaking.
