Recharge Guide

Movement Caliber J810

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 240 days without additional charging. Outlined below are the full recharge

times from a complete discharge utilizing various light sources.

INDOOR LIGHT

OUTDOOR LIGHT

Fluorescent light at 6” distance

Office Light Incandescent light at 20” Distance Outdoors on a Cloudy Day Outdoors on a Sunny Day

See Below* 240 hours 120 hours 30 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:
