~4 hours provides a single day of power. Note: Leaving a watch under standard office light from a completely dead state can take up to 150+ hours to reach full capacity. Best Practices for Charging
: The first four alphanumeric characters (e.g., E870, H800, B642) represent your movement caliber.
To properly operate your watch, it helps to understand what the markings on your case back mean:
Turn the crown to adjust the main time.
Use a soft cloth to wipe away sweat and dirt. Use a soft toothbrush with mild soap and water for stainless steel bracelets.
However, the specific reference is a less common variant within the massive Citizen catalog. Many owners struggle to find a dedicated manual because this reference is often grouped with the Caliber H500 or H504 movement families.
Visit the official website. Navigate to "Customer Service" > "Instruction Manuals." Select "Eco-Drive" then "Chronograph" and match your dial layout to the H500 drawing.
To recharge your watch, expose the dial directly to a strong light source. Ensure the face is pointing upward toward the light.
The Citizen Eco Drive GN-4W-S-12G is a part of Citizen's esteemed Eco Drive series, which harnesses the power of light to generate electricity, eliminating the need for battery replacements. This eco-friendly approach not only reduces waste but also provides a reliable and accurate timekeeping experience.
