Features of the solar watch
Running time
Expected running time from full charge to stoppage will be around 6 months.
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.
Unlike conventional quartz watches, this watch does not use a silver oxide battery, thus eliminating the need
for battery replacement.
Quick start function
It start running within a few seconds after exposure to a light more than 1000 Lx.
(Fluorescent lamp 30W/ 70cm)
Over charge prevent function
If the secondary battery is charged more than predetermined voltage, over charge prevent function is
operated to prevent the secondary battery deterioration and breakage.
How to charge and start the watch
Charging the watch
Caution
When charging the watch, do not place it too close to fluorescent lamp or other light sources as the watch
temperature will become extremely high, causing damage to the parts inside the watch.
(1) Expose the watch to sunlight or strong artificial light (of more than 1,000 Lx).
When the watch has stopped operating, the second hand will start moving at two-second intervals.
(2) Keep the watch exposed to the light until the second hand moves at one-second intervals.
(3) When the watch is charged after it has completely stopped, set the date and time before wearing
the watch.
When you start the watch or when the energy remaining in the secondary battery is very low, charge it
sufficiently by exposing the watch to light.
- The second hand immediately starts moving at two-second intervals, but the energy stored in the secondary
battery is not yet sufficient. If the watch is turned away from the light, it may stop operating.
It is not necessary to charge the watch fully. It is important, however, to charge the watch sufficiently, especially
in the case of initial charging.
To prevent energy depletion
• Avoid covering the watch face with your clothing while wearing it.
• When the watch is not in use, leave it in a brightly lit place for as long as possible.
Make sure that the watch temperature does not exceed 50
℃
.
When the energy stored in the secondary battery is reduced to an extremely low level, the second hand
starts moving at two-second intervals instead of the normal one-second intervals. In that case, recharge the
watch as soon as possible by exposing it to light. Otherwise, the watch may stop operating in about 1 day.
