This watch uses a secondary battery to store electrical energy. When the watch is
fully charged, it will maintain its accuracy for about 9 months.
<Ensuring best operation of the watch>
To receive the greatest pleasure from your watch, always store it in a
sunlit location.
jPlacing the watch near a window where its face can
receive sunlight or near another source of light when
you are not wearing it will ensure that the watch is
regularly charged, allowing it to maintain its accuracy.

jWearing clothes with long sleeves makes it difficult
for the watch to get the necessary light, resulting in
insufficient charging.
It is recommended to charge your watch by
exposing to direct sunlight for a long time once a
month.
[NOTE]
Do not charge on surfaces that can easily
become hot, such as a car dashboard.

5. Characteristics of the Solar Powered Watch
When the watch is insufficiently charged, the indication will be changed as follows:
<When the watch stopped due to an insufficient charging>
Charge the watch sufficiently, as indicated in “Guide to Charging Time”.
At this time, be sure to charge the watch with sunlight rather than under fluorescent
light.
[Normal indication]
The watch will stop
due to an insufficient
charging.
[Operation stops]
The second hand
starts moving at 2-
second intervals.
[Insufficient charge warning]
(Models with a second hand only)
The watch has been insufficiently
charged because the watch face
has not received sufficient light.
The insufficient charge
warning (a 2-second interval
movement) continues for
more than 7 days.
The watch has been insufficiently
charged because the watch face
has not received sufficient light.
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.

C. Quick Start (models with a second hand only)
If the watch stops due to insufficient charge, the second hand will start moving at
2-second intervals if the watch face is exposed to light (approx. 500 lx) for approx.
10 seconds. (The time required for the hand to begin moving varies depending on
the model.) Note, however, that the battery is not yet fully charged.
D. Guide to Charging Time
The charging time varies according to the model (including the color of the watch
face). The following data should only be used as a guideline.
* The charging time is based on continuous exposure.
For a 1-day movement charging time......
The charging time to run the watch for one day with normal movement.
Time for full charging......
The time for full charging after the watch has stopped due to an insufficient
charging.

[NOTE]
A fully charged battery will run the watch for about 9 months without further
charging.
If the watch stops due to insufficient charge, take care to charge it daily.
Furthermore, it is recommended to charge your watch by exposing to direct sunlight
for a long time once a month.

E. Handling Your Watch
WARNING Handling the secondary battery
jDo not remove the secondary battery from the watch yourself, unless
unavoidable.
If you must remove the battery, store it out of reach of children to avoid
accidental ingestion. If the secondary battery is ingested, consult a doctor
immediately.
jDo not throw away with regular trash.
Doing so could cause a fire or environmental damage. Follow the collection
procedures as specified by your local authority.
WARNING
Do not use anything other than the specified secondary battery
jThe watch will not operate if incorrect battery types are inserted.
Never use a regular silver battery. The battery could overcharge during the
charging process and burst, causing damage to the watch or injuries to the
wearer.
CAUTION Charging precautions
jDo not charge the watch in a high-temperature environment (about 60°C/140°F
or more).
Overheating while charging can cause the watch exterior to become discolored,
the watch to deform or the movement to be damaged.
Example:
• Charging close to incandescent lighting, halogen lamps, or other lighting
sources that easily become hot.
• Charging on surfaces that can easily become hot, such as a car dashboard.
jWhen charging with incandescent lighting, halogen lamps, or other lighting
sources that easily become hot, place the watch at least 50 cm (20 in.) away
from the source to avoid overheating.
