Citizen Eco-Drive – sensible use of energy. Even with all the precision, regular quartz watches have a major drawback – short battery lives. Alternative energy and/or advanced power management system for environmentally-friendly quartz timepieces have become the norm. Exclusively developed by Citizen, Eco-Drive technology combines low cost, eco-friendliness and aesthetics. It converts both natural and artificial light into electrical energy. An energy storage cell is used to store the electricity from the converted light energy, so no battery change is needed. This means saving money, no hazardous waste created by old batteries, and the watch case cannot be damaged. Eco-Drive watches are particularly environmentally-friendly and cost-effective.
