With everyday use in natural and artificial light, Citizen Solar-Tech series watches use Eco-Drive technology to continuously recharge themselves. Eighteen holes of golf or a weekend soccer match on a sunny day can generate a full charge for up to 6 months of running time for many Solar-Tech models. It’s incredible! It’s the power of Eco-Drive.

Sunlight and any artificial light are absorbed through the crystal and dial. Citizen uses special filters which allow a wide range of dial colors and styles.

A solar cell beneath the dial converts any form of light into electrical energy to power the watch. With regular exposure to light, Eco-Drive continuously recharges itself for a lifetime of use.
