1.Solar-powered watch
2. Eliminating the need for battery replacement
3. You can use the dial which light transmittance is more than 30%
It is possible to assemble the dial which transmits light on the solar cell.
It enabled to cover the solar cell color, and you can design variety colors of dials.
4. Running time
Expected running time from full charge to stoppage will be around 4 months.
5. Power depletion warning function
The two-second intervals movement of the second hand is a signal of energy depletion.
The watch continuous running time after two-second intervals movement is approximately 1 day.
6. Structure of the separated parts
Unlike conventional quartz watches, this watch does not use a silver oxide battery, thus eliminating the
need for battery replacement.
This watch is a solar-powered watch containing a solar cell underneath the dial to convert any form of
light into '' electrical energy'' and store the power in a secondary battery.
