j Wearing clothes with long sleeves makes it difficult
for the watch to get the necessary light, resulting in
insufficient charging.
It is recommended to charge your watch by
exposing to direct sunlight for a long time once a
month.
[NOTE]
Do not charge on surfaces that can easily
become hot, such as a car dashboard.
