This watch uses a secondary battery to store electrical energy. When the watch is
fully charged, it will maintain its accuracy for about 6 months.
Always store the watch in a bright location for best results.
j
Placing the watch near a window where its face can
receive sunlight or near another source of light when
you are not wearing it will ensure that the watch is
regularly charged, allowing it to maintain its accuracy.
j
Wearing clothes with long sleeves makes it difficult for the watch to get the
necessary light, resulting in insufficient charging.
We recommended that you charge the watch for a long time in direct sunlight
once a month.
[NOTE]
Do not charge on surfaces that can easily
become hot, such as a car dashboard.
