<Overcharging Prevention Function>
The overcharging prevention function is activated when the secondary battery is
fully charged so that it is not charged further.
<Power Save Function>
When power is no longer generated as a result of light not shining on the solar cell
continuously for 2 hours, the second hand stops at the 12:00 position and the watch
enters the Power Save state to reduce power consumption of the secondary battery.
The minute hand stops simultaneous to stopping of the second hand. The hour
hand continues to keep time by moving at one-hour intervals, and the date changes
with the movement of the hour hand. The power save function does not operate
when the crown is pulled out.
Note: The power save function is not activated even when power is not generated
as a result of light not shining on the solar cell during the time the second-
ary battery is fully charged and the overcharging prevention function is
activated.
<Canceling Power Save>
The power save function is canceled when the solar cell is exposed to light and
power generation is resumed. The minute and second hands advance rapidly to the
current time and begin moving.
