Eco-Drive Technology: Solar Power That Never Quits

How Eco-Drive Works

Citizen’s Eco-Drive is a game-changing solar-powered movement that converts any light source—natural or artificial—into energy. That power is stored in a permanent rechargeable cell, eliminating the need for battery replacements.

Advantages Over Quartz and Automatic Movements

• No battery swaps = less maintenance

• Always running if exposed to light

• More accurate than most mechanical movements

• Environmentally friendly (no disposable cells)

Power Reserve and Battery-Free Longevity

Eco-Drive watches can store power for up to 6 months in total darkness. With even occasional light exposure, you’ll virtually never run out of juice—making it one of the most reliable movements on the market.
