E168 Smartwatch
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 180 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* | 120 hours |
OUTDOOR LIGHT
| Outdoors on a Cloudy Day | Outdoors on a Sunny Day |
|---|---|
| 35 hours | 11 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: http://www.citizenwatch.com/en-us/support/setting-
instructions/
