Even if the watch is not charged for the time specified in the column, the 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.
(*) The values in this column represent the charging times required until the second hand moves constantly at one-second intervals
after the watch starts operating with the second hand moving at two-second intervals.
• The stopwatch can measure up to 29'59'' in one-second increments.
