<Overcharging Prevention Feature>
This enables the wearer to recharge without risk of
damage to the watch. When the secondary battery
is fully charged, the overcharging prevention feature
is activated to prevent further recharging.
<Power Save Feature>
* When light is not supplied to the solar cell and
power generation stops, the second hand stops at
the zero second position, to set in the power save
state. Although the second hand is stopped, the
hour and minute hands continue to move correctly
and the calendar is adjusted linked with the hour
and minute hands.
* Power save under normal hands movement
The second hand stops at the zero second
position, and when power generation begins, the
second advances rapidly to catch up with the
current second and then resumes the normal 1-
second interval movement.
* Power save under recharging warning (2-second
interval movement)
The second hand stops at the zero second position,
and when power generation begins, the second
advances rapidly to catch up with the current
second and then resumes the 2-second interval
movement.
* Power save under time setting warning (2-second
hitch movement)
The second hand stops at the zero second
position, and when power generation begins, the
second advances rapidly to catch up with the
current second and then resumes the 2-second
hitch movement.
* Power save under calendar setting warning
(5-second interval movement)
The second hand stops at the zero second
position, and when power generation begins, the
second advances rapidly to catch up with the
current second and then resumes the 5-second
interval movement.
(Note) When the secondary battery is fully charged
and overcharging prevention is activated, the
power save does not even work even when
light is not supplied to the solar cell and power
generation is not done. Likewise, the power
save feature does not work either when the
solar cell is fully charged temporarily by a
sudden supply of intense light.
4. Charging Times
The time required for charging varies according to
the model of watch (colour of the watch face, etc.).
The following table provides a general reference for
determining charging times.
* The charging time is continuous irradiation time.

Time required for full charge: Time from the state
in which the watch has stopped until fully charged.
Time required for one day's use: Time required for
the watch to run at 1-second intervals for one day.
5. Notes Regarding Handling of Solar-Powered
Watches
<Always Make Sure to Recharge Frequently>
Please note that if you wear long sleeves, the watch
may stop as a result of being covered by your sleeve
and blocked from the light.
* When you take off the watch, try to place it in as
bright a location as possible.This will ensure that it
will continue to run.
• When not using the watch for a long period, we
recommend storage under power save state to
save power for a longer retention time.
Recharging Precautions
• The watch will be damaged during recharging if it
becomes excessively hot (60 C/140 F). Avoid
recharging when the watch is hot.
Examples: Recharging when the watch is in close
proximity to an incandescent lamp, halogen lamp
or other light source that generates considerable
heat, or recharging the watch while placed on the
dashboard of an automobile or other locations
subject to excessively high temperatures.
• When you charge the watch by an incandescent
lamp, take a distance about 50cm (20 in.) from the
light source to prevent extremely high temperature.
6. Replacement of Secondary Battery
Since the secondary battery used in this watch is
able to be charged and discharged repeatedly, it
does not have to be replaced periodically in the
manner of ordinary batteries.
