1. Features
This is an analog solar-powered watch that is equipped with a solar cell incorporated in its face
to convert solar energy into electricity. The watch is also equipped with the large and highly
visible date indicator and the fan-shape 24-hour dial.
2. Before Using
Sufficiently Recharge by
Placing in Light Before Use
A secondary battery is used in this watch to store electrical energy. This secondary battery
is a clean energy battery that does not contain mercury or other toxic substances. Once fully
charged, the watch will continue to run for about 6 months without additional charging.
<How to use this Solar Watch Properly>
To use this watch comfortably, make sure to recharge the watch before it stops running
completely. Since there is no risk of overcharging (Overcharging Prevention Feature), it is
recommended that the watch be recharged everyday.
