Find yourself asking What is Eco-Drive Technology?

Basically it means it is a solar powered watch.

Citizen Eco Drive is simple, yet revolutionary concept, a timepiece that never needs a battery change.

How does that work?

Citizen Eco-Drive harnesses the power of light-from any natural or artificial light source – and converts it into energy which is stored in a Eco-Drive energy cell. 

It recharges continuously in any kind of light to run forever.

What does that mean?

So that means no more messing around tracking down and putting in tiny watch batteries, your watch just keeps on going.
