• The level of power generation amount indicated is that of the moment you
operate the watch for its indication. The level indication does not reflect change
of the level after your operation.
• The level may vary even under the same brightness due to the entry angle
of light to the dial of the watch or other elements. The level may also vary
depending on difference of models.
• The light level indication of “6”, indicates light being received is equivalent to a
cloudy outdoors (about 10,000 lux illuminance) or a brighter location.
• Use the level of power generation amount as a general reference only.

Charging your watch
This watch has a solar cell under the dial and stores the power
generated by the cell in its built-in rechargeable cell.
The cell is charged by exposing the dial to light such as direct
sunlight or fluorescent lamps.
For optimal performance, be sure to:
• Put the watch in a location where the dial is exposed to
bright light such as by the window even when it is not used.
• Expose its dial to direct sunlight for 5 or 6 hours at least
every half-a-month.
• Avoid leaving it in dark places such as in a drawer for long
periods of time.
48
Page 49
Chargi ng your watch
CAUTION
• This watch contains a large-capacity rechargeable cell for performing powerconsuming satellite signal reception. This large capacity cell takes more time to
charge than those found in other Eco-Drive watches.
• If the surrounding temperature falls below 0°C (32°F) or exceeds 40°C (104°F),
the “Charge suspension temperature detection function” will activate and
charging will not be possible.
• Do not charge the watch at a high temperature (about 60°C (140°F) or higher)
as doing so may cause movement malfunction.
• If the watch is obscured from light by long sleeves frequently, supplemental
charging may be needed to ensure continual operation.
• The watch stops charging automatically after finishing (overcharging prevention
function). The function prevents damage to performance of the watch and
rechargeable cell due to overcharging.
49
Page 50
Chargi ng your watch
When the watch reaches a low charge state (insufficient charge warning
function)
When the power reserve becomes low, the second hand
moves once every two seconds. This is the insufficient
charge warning function. Be sure to fully charge your watch
immediately as outlined below.
• When the watch is sufficiently charged, the second hand
will move normally.
• If you do not charge the watch for 5 days or longer after the insufficient charge
warning movement has begun, the watch will be depleted of all power and stop.
CAUTION
• If you do not charge the watch for 30 days after it has stopped, recharging will
not be possible (over discharge detection function).
• Consult an authorized service center if no hands start to move even after
charging a stopped watch for one day or more exposing to direct sunlight.

Information on satellite signal reception
This watch receives time information from satellites to indicate the time and
calendar.
It also obtains location information from them to indicate time appropriate in the
area where it is actually used.
For receiving the satellite signal smoothly
Satellite signal reception is power consuming. Take care of power reserve when
executing reception.
• This watch keep moving in average monthly accuracy of ±5 seconds even without
receiving the satellite time signal.
• Use the function to see the result of the previous reception (success or fail) (page
) effectively to try to execute reception in best frequency.

Cautions regarding receiving the satellite signal
Do not perform signal reception while operating a vehicle as doing so is
extremely dangerous.
• If the second hand is moving once every two seconds (insufficient charge warning
function), you cannot perform satellite signal reception. Charge the watch
sufficiently before attempting signal reception.
• Even when this watch receives the signal successfully, the accuracy of the
displayed time will be dependent on the reception environment and internal
processing.
• The automatic correction feature of this watch is supported until 28/2/2100.
• Summer time (DST) information is not contained in the satellite signal. Adjust
the setting manually before and after the summer time (DST) period. (page
)
44
55
Page 56
Informa tion on sate llite signa l receptio n
When receiving the satellite signal
• As shown in the picture below,
make sure you are in an area with
few surrounding trees, buildings, or
other objects which may obstruct the
satellite signal. Face the dial towards
the sky and perform signal reception.
• For successful reception there should
be a clear view of the sky as depicted
in the illustration when attempting to
receive the satellite signal.
• Reception may fail due to the
positions of satellites when you try to
receive their signals.
56
Page 57
Informa tion on sate llite signa l receptio n
Receiving signals indoors near a window
Place the watch near a window with a wide view of
the sky and orient the dial in an obliquely upward
direction to the sky.
• Signal reception from some satellites is required
for obtaining location information. So it is
possible that location information cannot
be obtained in an environment where time
information can be received.
Outdoor signal reception is recommended for
obtaining location information.
• It may be difficult to receive satellite signals through special types of window
glass.
57
Page 58

Poor reception areas
It may be difficult to receive the satellite signal under certain environmental
conditions or in certain areas.
Areas with obstructions above the watch Nearby objects which emit magnetism or noise
• High-voltage electric cables, railway
• Indoors or underground
• Areas surrounded by tall bui ldings or
trees
• When the weather is cloudy or rainy, or
during a thunderstorm

Checking and adjusting the leap second setting
This watch displays the time by applying the leap second to the International
Atomic Time information received from satellites.
• The leap second may be applied once a few years and the leap second setting on
the watch must be adjusted each time it applied.
• The leap second setting can be adjusted by executing leap second reception (page
). It can also be set manually.

Eco-Drive watch handling precautions
<Always Make Sure to Recharge Frequently>
• For optimal performance, your watch should remain fully charged.
• Long sleeves may inhibit light transmission to your watch.
This may result in your watch loosing charge. In these cases
supplemental charging may be necessary.
• When you take off the watch, place it in a bright location to ensure
optimal performance.
86
Page 87
CAUTION
• Do not charge the watch at a high temperature (about
Recharging Precautions
60 °C (140 °F) or higher) as doing so may cause the
movement to malfunction.
Examples:
• Charging the watch too close to a light source
which generates a large amount of heat such as an
incandescent lamp or halogen lamp.
* When charging under an incandescent lamp, be
sure to leave 50 cm (20 inches) or more between the
lamp and the watch to avoid exposing the watch to
excessive heat.
• Charging the watch in a location where the temperature
may become extremely high such as on the dashboard
of a vehicle.

<Replacement of Rechargeable Cell>
• This watch utilizes a special rechargeable cell that does not require periodical replacement.
However power consumption may increase after using the watch for a number of years due
to wear of internal components and deterioration of oils. This may cause stored power to
be depleted at a faster rate.
WARNING
• The rechargeable cell should never be removed from the watch.
If for any reason it becomes necessary to remove the rechargeable cell from the watch, keep
out of the reach of children to prevent accidental swallowing.
If the rechargeable cell is accidentally swallowed, consult a doctor immediately.
• Do not dispose of the rechargeable cell with ordinary garbage. Please follow the instructions
of your municipality regarding collection of batteries to prevent the risk of fire or
environmental contamination.
Handling of Rechargeable Cell
88
Page 89
WARNING
Eco-Dri ve watch handl ing precau tions
Use Only the Specified Battery
• Never use a battery other than the rechargeable cell specified for use in this watch.
Although the watch structure is designed so that it will not operate when another type of
battery is installed, if a conventional watch battery or other type of battery is installed in
the watch and the watch is recharged, there is the risk of overcharging which may cause the
battery to rupture.
This can cause damage to the watch and injury to the wearer.
When replacing the rechargeable cell, always make sure to use the designated rechargeable
cell.

<When Luminous Paint is used for your watch>
The paint on the dial and hands helps you with reading the time in a dark place. The
luminous paint stores light (daylight or artificial light) and glows in a dark place.
It is free from any radioactive substance or any other material harmful to a human body or
environment.
• The light emission will appear bright at first and then diminish as time passes.
• The duration of the light (“glow”) will vary depending on the brightness, types of and
distance from a light source, exposure time, and the amount of the paint.
• The paint may not glow and/or may dissipate quickly if exposure to light was not sufficient.
