A. Power Saving Function
If the watch face is not exposed to light for a long time, the power saving function is activated
to minimize the battery consumption.
• Power saving 1: When power is not generated for more than 30 consecutive minutes, the
digital displays go off to save power.
• Power saving 2: When the power saving 1 condition continues for 7 days or longer, to save
power, the hour hand, minute hand, second hand and 24-hour hand move to
the reference position, and the charge level indicator and UTC hands (hour
and minute) stop in their current positions.
• The correct time continues to be kept inside the watch.
• The alarm tone will not sound.
