Citizen Eco Drive J250 Manual

Eco Drive Recharge Guide
Your Eco Drive watch does not operate on a conventional battery. It is powered by light that is converted
to energy that is stored in a special cell. This cell provides a reserve of power that is used when the
watch is not receiving light sufficient for operation and charging.
It is best to expose your watch to light daily to ensure optimal performance. Once fully charged, your
timepiece will run for up to 300 days without additional charging. Outlined below are the full recharge
times from a complete discharge utilizing various light sources.
INDOOR LIGHT
Fluorescent light at 6" distance
Office Light Incandescent light at 20" Distance
See Below* 280 hours
*Usually, overhead office light is insufficient to achieve a full charge from a completely depleted power reserve.
Optimal charging is achieved with direct outdoor sunlight (not through a window). Sunlight through a window
provides less energy than direct outdoor light due to glass filtering and coatings. If charging under this condition,
double the specification for outdoor light on a cloudy day.
After fully charging your watch from a complete discharge or some other malfunction, be sure to perform the ALL
RESET outlined in your instruction book. You may also find instruction sets on our web site at:
