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.
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.
