The figures in the table above refer to the time required to charge the stopped watch by exposure to light until the
watch moves at steady one-second intervals, through two-second intervals and five-second intervals.
Even if the watch is partially charged for a period shorter than the time provided in the above table, it will resume
one-second interval movement; however the one-second interval movement will change to two-second interval
movement shortly. To avoid this and charge the watch to a sufficient level, use the charging time mentioned above
as a measure.
*The required charging time slightly varies depending on the model of the watch.
CHARGING THE SOLAR BATTERY
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.
HOW TO CHARGE THE WATCH
To enjoy optimal performance
of this watch, it is recommended
that the watch be kept sufficiently
charged at all times.
*Before initially using the watch
or when the watch has stopped
as a result of complete depletion
of stored power, charge the watch
sufficiently.
*The table above is only provided as an approximation.
