Eco-Drive technology

40 years of Eco-Drive

In 1976, 40 years ago this year, CITIZEN created the world’s first analogue light-powered watch. We called the technology Eco-Drive. With Eco-Drive, our watches generate energy even from dim light and keep running for months even in the dark. We have created watches with multi-functions; watches that are smaller, thinner, and more beautiful; watches that everyone can relate to, even love. As a light-power pioneer, we continue to explore new possibilities for the future of the wristwatch and to craft timepieces that inspire people everywhere.

What is Eco-Drive?

Eco-Drive is a core CITIZEN technology that generates power even from dim light, enabling watches to run for over six months* even in the dark.

■No need to replace batteries
Eco-Drive eliminates the trouble and expense of regularly replacing batteries.
■Generates energy even in dim light
Eco-Drive generates energy not just in sunlight but in indoor light too. You don’t need to worry about your watch ever stopping.
■Runs for over six months in the dark
One full charge is enough to keep most Eco-Drive models running for more than six months* in darkness. Some models can run for 10 years.
*Some models run for less than six months.

Eco-Drive - All you need is light

Eco-Drive will keep running wherever you are, as long as there is light. Inspired by its innovative technology, people all around world give their Eco-Drive watches a special place in their lives. Here are their stories.
