For a 1-day movement charging time ... The charging time to run the watch for one day
with normal movement.
Time for full charging ... The time for full charging after the watch has stopped due to an
insufficient charging.
[Caution] A fully charged battery will run the watch for about 6 months without further
charging. During power saving mode, the correct time continues to be kept
inside the watch for approximately three and a half years.
Charge the watch every day, as it will take a long time to recharge it, as is
indicated in the table, when it stops due to an insufficient charging.
Furthermore, it is recommended to charge your watch by exposing to direct
sunlight for a long time once a month.
