(*) The values in this column represent the charging times required until the small second hand moves constantly at one-second intervals
after the watch starts operating with the small second hand moving at two-second intervals.
Even if the watch is not charged for the time specified in the column, the small 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.
