6. General Reference for Charging Times
e time required for charging varies according to the model of the watch (color of
the dial, etc.). e following times are shown below to serve only as a reference.
Full charging time: Time required for charging the watch from the stopped state to fully charged.
Charging time for 1 day of operation: Time required for charging the watch to run for 1 day at
1-second interval movement.
[Note]
Once fully charged, the watch will continue to run for about 6 months
with any additional charging. As shown in the table above, a considerable
amount of time is required until the watch starts running once the watch
has stopped as a result of being insuciently charged. Try to keep your
watch suciently charged at all times by charging everyday.
Furthermore, it is recommended to charge your watch by exposing to
direct sunlight once a month.
