What is the ideal source of power for a watch?
CITIZEN created the world’s first light-powered analogue quartz watch in 1976.
Citizen named the technology Eco-Drive in acknowledgement of its eco-friendly origins.
It converts any kind of light into energy to power a watch and stores the surplus on a power cell.
On a full charge, an Eco-Drive watch runs for months even in darkness with no need for regular battery replacement.
As a light-power pioneer, we continue exploring new possibilities.
Runs for over six months even in darkness
Do you need light to generate power for your watch all the time? Not with Eco-Drive. A single full charge is enough to keep Eco-Drive working for over six months in total darkness. Indeed, some models equipped with power save function can run for as long as seven years.
* Some models run for less than six months.
No need for regular battery replacement
Once upon a time, everyone accepted that quartz watches had to have their batteries replaced at regular intervals. But the advent of Eco-Drive overturned the conventional thinking. Eco-Drive is a light-powered technology that drives watches by capturing light and converting it into energy using an inbuilt solar cell.
Suddenly the hassle of replacing batteries was a thing of the past.
Runs even in dim light
Eco-Drive is designed to charge from ordinary everyday light sources like indoor fluorescent lighting and desk lights. You can go about your everyday life confident that your watch will never stop.
* To get the most out of your watch, set aside about five or six hours per month to charge it in sunlight.
In line with its “Better Starts Now” brand statement, CITIZEN has developed Eco-Drive watches that are smaller, thinner, lighter and have more functions. In fact, Citizen have produced a whole series of world firsts. With our focus on functionality, convenience and beauty, CITIZEN will keep innovating and improving in the years ahead.
