CHARGING THE SOLAR BATTERY

English
	HOW TO CHARGE THE 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.
	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.

★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.
