Solar Charging
This watch runs on power supplied from a rechargeable (secondary) battery that is charged by a solar panel. The solar panel is integrated into the face of the watch, and power is generated whenever the face is exposed to light.
Charging the Watch
When you are not wearing the watch, put it in a location where it is exposed to bright light.
While you are wearing the watch, make sure that its face (solar panel) is not blocked from the light by the sleeve of your clothing. Power generation efficiency is reduced even when the face of the watch is blocked only partially.
Remaining Charge and Dead Battery
The charge level is indicated by watch hand movement. Functions become disabled as battery power goes low.
Low Battery Power
The second hand jumps at two-second intervals.
Dead Battery
All hands and the day indicator are stopped.
