What is Eco-Drive?

Eco-Drive is Citizen’s groundbreaking, light-powered technology, fundamentally changing how watches are powered. Unlike conventional quartz watches relying on batteries, Eco-Drive utilizes light – any light – as its energy source. This includes sunlight, indoor lighting, and even dim fluorescent lights.

The watch contains a specialized solar cell beneath the dial, converting light into electrical energy. This energy charges a rechargeable lithium-ion cell, acting as the watch’s power reserve. A key benefit is the elimination of battery changes, reducing waste and maintenance.

Eco-Drive watches are designed for continuous operation as long as they are exposed to sufficient light. This manual will guide you through understanding the reserve indicator and ensuring optimal performance of your Citizen watch.

The Core Principles of Light-Powered Technology

Citizen Eco-Drive’s core relies on photovoltaic conversion – transforming light energy into electrical energy. The solar cell, discreetly integrated within the watch, captures light from various sources, not just direct sunlight. This captured light then generates electricity, charging a rechargeable lithium-ion battery.

This battery stores the excess energy, creating a power reserve. This reserve allows the watch to function in darkness for a defined period, varying by model. Crucially, Eco-Drive eliminates the need for traditional battery replacements, promoting sustainability and convenience.

Understanding these principles is vital for optimal watch care. This manual details handling precautions and charging guidelines to maximize your Eco-Drive watch’s lifespan and performance.
