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.
