A. Overcharging Prevention Function
No matter how much the watch is charged, it will not affect the secondary battery,
timekeeping, functions or performance of the watch. When the secondary battery
becomes fully charged by exposing the watch face to light, the overcharging
prevention function is automatically activated to prevent the battery from being
charged further.
B. Insufficient Charge Warning Function
(models with a second hand only)
The second hand's movement changes from 1-second
intervals to 2-second intervals to show that the watch
is insufficiently charged.
The watch will stop due to insufficient charging
about 7 days after starting the 2-second interval
movement if kept in a place with no light.
