The Eco-Drive technology by Citizen is a wristwatch innovation that powers watch models by the company with light. A rechargeable lithium-ion battery in the timepiece models is connected to a photovoltaic cell that absorbs artificial and natural light and converts it into electrical energy.
The Eco-Drive was designed by Citizen and launched in 1995. It was designed as a means to end the production of wasteful disposable watch batteries that commonly contain toxic chemicals. The Eco-Drive was also hailed as a convenience to consumers as a watch that never needed a battery change, especially for hard-to-find specialized models. The technological breakthrough for light-driven watches occurred in the company in 1976, although the need for a miniaturized battery system took another 19 years to develop.
Citizen Eco-Drive watches are available for purchase from the main company website, or from a variety of retailers worldwide. They retail from $145 to $2,650 as of 2015.
Citizen, a Japanese watch-making corporation, has produced high-end watches since its founding in 1930, dedicated to providing service to customers while working to bring about a corporate culture that positively impacts the world. The brand utilizes, as of 2015, well-known ambassadors like artist Kelly Clarkson, professional football player Eli Manning, professional race car driver Matt Kenseth and professional tennis player Victoria Azarenka. These celebrities are spokespeople for the Better Starts Now advertising campaign.
