D. Guide to Charging Time
The following values are guidelines for when the watch face is being continuously
exposed to the light.
The table can be used to find an estimate of the amount of energy that the watch can
store depending on the environment and amount of time the watch is charged.
For example, you can see that the energy that can be stored when the watch is subjected
to approximately 4 hours of light under cloudy skies is sufficient to operate the watch for
about 20 days.

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.
[NOTE] A fully charged battery will run the watch for about 7 months without further
charging.
The watch will maintain its accuracy for about 2.5 years when running in the
power saving mode. 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. It is recommended to charge the watch by exposing to direct sunlight
for a long time once a month.
