· Charging time for 1 day of operation: Time required for charging the watch to run for 1
day at 1-second interval movement.
· Full charging time: Time required for maximally charging the watch when it is stopped
due to being insufficiently charged.
[NOTE]
* The watch will continue to operate for about 9 months without additional charging
once it has been fully charged. Once the watch has stopped as a result of being
insufficiently charged, a considerable amount of time is required until it starts to run
again as indicated in the table above. It is therefore recommended to charge your
watch everyday. Furthermore, it is recommended to charge your watch by exposing to
direct sunlight once a month.
