Guidelines for charging time
The below table provides only general guidelines.
(Dial transparency rate is 30%)
Condition A : Time required for full charge
Condition B : Time required for steady operation
Condition C : Time required for 1 day's charge
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.
