FAQs
Do I ever need to replace the battery?
No, the Eco-Drive movement is powered by light and uses a special capacitor that does not require the traditional battery changes of a standard quartz watch.
Is this watch suitable for swimming?
Yes, with 100 meters of water resistance, it is perfectly fine for swimming and snorkeling, though it should not be used for deep-sea scuba diving.
How long does it take to fully charge?
A full charge from a depleted state can take several hours in direct sunlight, though daily exposure to normal office or outdoor light is enough to keep it topped up.
Can I wear this watch in the dark?
Yes, once fully charged, the watch will continue to run for several months in total darkness.
Is the 37mm size considered unisex?
Yes, the 37mm case is a classic size that is widely considered gender-neutral and fits both smaller and medium-sized wrists comfortably.
Troubleshooting
Watch has stopped moving after storage
Expose the watch face to direct sunlight or a strong indoor light source for at least 8-12 hours to recharge the capacitor.

Setup, Compatibility & Care
Setting up the Citizen Eco-Drive is straightforward. Simply pull the crown to the first or second click to adjust the date and time respectively, then push it back in to seal the movement. To ensure the Eco-Drive capacitor stays charged, avoid storing the watch in a dark drawer for extended periods; keeping it in a location where it receives ambient light is sufficient to maintain its power reserve. To clean the watch, wipe the stainless steel case with a soft, lint-free cloth. If the watch has been exposed to saltwater, rinse it gently with fresh water and dry it thoroughly with a towel to prevent mineral buildup or corrosion.
