ECO-DRIVE TECHNOLOGIE
40 years of Eco-Drive
In 1976, CITIZEN developed the world's first analog, light-powered watch. We called the technology Eco-Drive. With Eco-Drive, our watches generate power even in dim lighting and run for months in the dark. We created watches with multi-functions; watches that are smaller, thinner and more beautiful; watches that everyone can relate to, even love. As a pioneer in lighting technology, we continue to explore new possibilities for the future of the wristwatch, making watches that inspire people everywhere.
What is Eco-Drive ?
Eco-Drive is a core technology from CITIZEN that generates power even in dim light and allows watches to run for over six months* even in the dark.
- No need to change batteries
Eco-Drive eliminates the hassle and expense of changing batteries regularly. - Generates energy even in dim light
Eco-Drive generates energy not only in sunlight, but also in indoor light. No need to worry about your clock ever stopping. - Runs for over six months in the dark.
One full charge is enough to keep most Eco-Drive models running in the dark for more than six months*. Some models have a runtime of 10 years.
Some models have a runtime of less than six months.
Sustainable
Approximately 4 million Eco-Drive watches are sold each year. This means that every year we save 4 million batteries that would otherwise have to be disposed of. Assuming that a battery is about 2.1 mm high , all these batteries create a tower 8,400 m high - almost as high as Mount Everest. In this way, we reduce a whole lot of waste and use natural energy instead.
