2. Eco-Drive Technology
Citizen Eco-Drive watches are powered by light, converting both natural and artificial light into energy. This energy is stored in a power cell, which then drives the watch movement. This eliminates the need for traditional battery replacements, contributing to environmental sustainability.

Charging the Watch:
To ensure optimal performance, expose your watch to light regularly. A full charge can last for several months, even in darkness. Avoid prolonged storage in dark places to prevent the watch from stopping.
- Direct Sunlight: Provides the fastest charge.
- Indoor Lighting: Also charges the watch, but at a slower rate.
- Charging Indicator: Some models feature a low charge indicator (e.g., second hand moving in two-second intervals) to alert you when charging is needed.

5. Maintenance and Care
Proper care ensures the longevity and performance of your Citizen watch.
Water Resistance:
Your watch is water resistant to 200 meters. This means it is suitable for showering, swimming, and snorkeling. However, it is not suitable for scuba diving. Always ensure the crown is pushed in completely before exposing the watch to water. Do not operate the crown or pushers while the watch is wet.
Cleaning:
Wipe the watch regularly with a soft, dry cloth to remove dirt and moisture. For the stainless steel bracelet, a soft brush with mild soapy water can be used, followed by thorough rinsing and drying.
Storage:
When not wearing the watch, store it in a location where it can receive light to maintain its charge. Avoid extreme temperatures and strong magnetic fields.
