The Watch Pocket Jewelers carries watches from the Citizen Signature Collection as well as the popular Eco-Drive Citizen watches.  The Eco-Drive technology harnesses the power of light-from any natural or artificial light source-and converts it into energy that is stored in a permanently rechargeable lithium-ion cell. It never needs winding because it continuously charges itself in any kind of light to run forever.  Thus, the Citizen Eco-Drive watches are a best-seller at The Watch Pocket Jewelers!
