CITIZEN Eco-Drive:
Our proprietary light-powered technology
After releasing the world’s first light-powered analog quartz watch in 1976, we continuously
worked to improve the technology.
Our new, light-powered technology delivered high energy
efficiency and long running time. That’s why we created the name ‘Eco-Drive.’ A fusion of the
words ‘Ecology’ and ‘Drive,’ the name sends a clear message of eco-friendly, socially
responsible watches that will keep running for a long time. Eco-Drive embodies our commitment to
sustainability.
