FEATURES OF THE SOLAR WATCH
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.
RUNNING TIME
Expected running time from full charge to stoppage will be around 4 months.
POWER DEPLETION WARNING FUNCTION
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.
HOW TO CHARGE AND START THE WATCH
• CHARGING 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.
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.
• 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.
• 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˚C.
GUIDELINES FOR CHARGING TIME
The below table provides only general guidelines.

Condition A : Time required for full charge
Condition B : Time required for steady operation
Condition C : Time required for 1 day's charge
(*) The values in this column represent the charging times required until the second hand moves
constantly at one-second intervals after the watch starts operating with the second hand moving at
two-second intervals.
Even if the watch is not charged for the time specified in the column, the second hand may temporarily
move at one-second intervals. But it will soon resume moving at two-second intervals; therefore, charge
the watch for more than the specified period.
