Insufficient Charge Warning Function
The second hand changes to a two second
interval movement to indicate insufficient
recharging.
Even in such a case, the watch keeps correct time,
but about 3 days after the two second interval
movement begins, the watch will stop.
After exposing the watch to light, recharging takes
place and the watch returns to one second interval
movement.
WW
Quick Start Function
The watch will stop if it is completely discharged.
It will begin to operate soon after it is exposed
to light.
(However, the time to start may vary according to
the brightness of the light.)

Time Setting Warning Function
If the watch stops, subsequent exposure to light
allows the Quick Start Function to start again, and
the second hand moves with a hitch to indicate
that the time is incorrect.
In this case, quickly recharge the watch and reset
the time.
Otherwise, the hitch movement will continue.
WW
Overcharge Prevention Function
There is no risk of overcharging.
Once the secondary battery is fully recharged, the
overcharging prevention feature comes into
operation and prevents overcharging.
