This watch includes a rechargeable cell. This cell is fed electricity by a
solar cell in which light energy is converted to electrical energy.
Product Features
The watch operates by converting sunlight into electrical energy, which is stored in a rechargeable
battery. e rechargeable battery is a clean energy source that does not contain mercury or other harmful
substances. When the watch is fully charged, it will operate continuously for approximately seven months.
A watch that has stopped due to an insuciently charged cell will start operating immediately
when exposed to light.
Special hand movement to let you know when the reserve energy is getting low.
is protects the rechargeable cell from overcharging. is provides worry free enjoyment,
not matter how much light your watch is subjected to.
This feature enables elapsed time measurement (stopwatch.) You can measure time in
activities such as walking, jogging, bicycle riding, etc.
