Citizen Casual Watch BM8186-07E

Eco-Drive | Purposeful Power

Citizen’s Eco-Drive technology powers your watch using natural or artificial light so you won’t have to worry about battery changes.

Light to Energy

Eco-Drive technology drives watches by capturing light and converting it into energy which is then stored in a permanently rechargeable lithium-ion cell.

Energy Storage

The watch keeps surplus energy in a rechargeable power cell. Designed to charge not just from the sun, but also from everyday light sources like indoor flourescents and desk lamps.

Recharges Continuously

Runs for months – even in darkness – with no need for costly battery replacements, so your watch can run forever and you never have to worry about it stopping.
