This watch has a rechargeable cell which is charged by
exposing the dial to light, such as direct sunlight or fluorescent
lamps (refer to page
66
for charging guidelines).
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 for long periods of time.
Charging your watch
63
English
Charging your watch
CAUTION
• This watch contains a large-capacity rechargeable cell for performing power-
consuming 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.
Continued on the next page
64
Charging 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 on page
66
.
• 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
Satellite signal reception is power-consuming. Be sure your watch has a sufficient
charge before executing reception.
• The average monthly accuracy of this watch is ±5 seconds even if a satellite signal
is not received.
• Use the function to see the result of the previous reception (success or fail) (page
31
) effectively to try to execute reception in best frequency.
69
English
Information on satellite signal reception
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
52
)
Continued on the next page
70
Information on satellite signal reception
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.
71
English
Information on satellite signal reception
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. It is possible
that location information cannot be obtained
while time information can be received in the
same place.
Outdoor signal reception is recommended for
obtaining location information.
• It may be difficult to receive satellite signals
through special types of window glass.

Water resistance
• Non-water resistant models are not designed to come into contact with any moisture. Take
care not to expose a watch with this rating to any type of moisture.
• Water resistance for daily use (to 3 atmospheres) means the watch is water resistant for
occasional accidental splashing.
• Upgraded water-resistance for daily use (to 5 atmospheres) means that the watch may be worn
while swimming, but is not to worn while skin diving.
• Upgraded water-resistance for daily use (to 10/20 atmospheres) means that the watch may be
worn while skin diving, but not while scuba or saturated diving using helium gas.

Precautionary items and usage limitations
CAUTION
To Avoid Injury
• Be particularly careful when wearing your watch while holding a small child, to avoid injury.
•
Be particularly careful when engaged in strenuous exercise or work, to avoid injury to yourself
and others.
• Do not wear your watch while in a sauna or other location where your watch may become
excessively hot, since there is the risk of burns.
• Be careful when putting on and taking off your watch, since there is a risk of damaging your
fingernails, depending on the manner in which the band is fastened.
• Take off your watch before going to bed.
106
Precautionary items and usage limitations
CAUTION
Precautions
•
Always use the watch with the crown pushed in (normal position). If the crown is of the screw
lock-type, make sure it is securely locked.
• Do not operate the crown or any push buttons when the watch is wet. Water may enter the
watch causing damage to vital components.
• If water enters the watch or the watch fogs up and does not clear up even after a long time,
consult your dealer or an authorized service center for inspection and/or repair.
• Even if your watch has a high level of water resistance, please be careful of the following.
- If your watch is immersed in sea water, rinse thoroughly with fresh water and wipe with a
dry cloth.
- Do not pour water from a tap directly onto your watch.
- Take off your watch before taking a bath.
• If seawater enters the watch, place the watch in a box or plastic bag and immediately take it in
for repair. Otherwise, pressure inside the watch will increase, and parts (crystal, crown, push
button, etc.) may come off.
107
English
Precautionary items and usage limitations
CAUTION
When Wearing Your Watch
<Band>
•
Leather bands and rubber (urethane) bands will deteriorate over time due to perspiration dirt.
Because of the natural materials, leather band will be worn, deformed, and discolored over
time. It is recommended to replace the band periodically.
•
The durability of a leather band may be affected when wet (fading, peeling of adhesive), owing
to the properties of the material. Moreover, wet leather may cause a rash.
• Do not stain a leather band with substances containing volatile materials, bleach, alcohol
(including cosmetics). Discoloration and premature aging may be occurred. Ultraviolet light
such as direct sunlight may cause discoloration or deformation.
• It is recommended to take off the watch if it gets wet, even if the watch itself is water-resistant.
• Do not wear the band too tightly. Try to leave enough space between the band and your skin
to allow adequate ventilation.
• The rubber (urethane) band may be stained by dyes or soil present in or on clothing or other
accessories. Since these stains may not be removable, caution is required when wearing
your watch with items that tend to easily transfer color (articles of clothing, purses, etc.). In
addition, the band may be deteriorated by solvents or moisture in the air. Replace with a new
one when it has lost elasticity or become cracked.
108
Precautionary items and usage limitations
CAUTION
When Wearing Your Watch (continued)
• Please request adjustment or repair of the band in the following cases:
- You notice an abnormality with the band due to corrosion.
- The pin of the band is protruding.
• We recommend seeking the assistance of an experienced watch technician for sizing of your
watch. If adjustment is not done correctly, the bracelet may unexpectedly become detached
leading to loss of your watch or injury.
Consult an authorized service center.
<Temperature>
• The watch may stop or the function of the watch may be impaired in extremely high or low
temperature. Do not use the watch in places where the temperature is outside the operating
temperature range as stated in the specifications.
<Magnetism>
• Analog quartz watches are powered by a step motor that uses a magnet. Subjecting the watch
to strong magnetism from the outside can cause the motor to operate improperly and prevent
the watch from keeping time accurately.
Do not allow the watch to come into close proximity to magnetic health devices (magnetic
necklaces, magnetic elastic bands, etc.) or the magnets used in the latches of refrigerator
doors, clasps used in handbags, the speaker of a cell phone, electromagnetic cooking devices
and so on.
109
English
Precautionary items and usage limitations
<Strong Shock>
• Avoid dropping the watch or subjecting it to other strong impact. It may cause malfunctions
and/or performance deterioration as well as damage to the case and bracelet.
<Static Electricity>
• The integrated circuits (IC) used in quartz watches are sensitive to static electricity. Please
note the watch may operate erratically or not at all if exposed to intense static electricity.
<Chemicals, Corrosive Gasses and Mercury>
• If paint thinner, benzene or other solvents or products containing these solvents (including
gasoline, nail-polish remover, cresol, bathroom cleaners and adhesives, water repellent, etc.)
are allowed to come into contact with the watch, they may discolor, dissolve or crack the
materials. Be careful when handling these chemicals. Contact with mercury such as that used
in thermometers may also cause discoloration of the band and case.
<Protective Stickers>
• Be sure to remove any protective stickers that may be on your watch (case back, band, clasp,
etc.). Otherwise, perspiration or moisture may enter the gaps between the protective stickers
and the parts, which may result in a skin rash and/or corrosion of the metal parts.
110
Precautionary items and usage limitations
CAUTION
Always Keep Your Watch Clean
• Rotate the crown while it is pressed in fully and press the buttons periodically so they do not
become stuck due to accumulations of foreign matter.
•
The case and band of the watch come into direct contact with the skin. Corrosion of the metal
or accumulated foreign matter may result in black residue coming from the bracelet when
exposed to moisture or perspiration. Be sure to keep your watch clean at all times.
• Be sure to periodically clean the bracelet and case of your watch to remove accumulated
dirt and foreign matter. In rare circumstances, accumulated dirt, foreign matter may cause
irritation with the skin. If you notice this, discontinue wearing the watch and consult your
physician.
• Be sure to periodically clean foreign matter and accumulated materials from the metal band,
synthetic rubber strap (polyurethane) and/or metal case using a soft brush and mild soap. Be
careful not to allow moisture on the case if your watch is not water resistant.
• Leather bands may become discolored by perspiration or dirt. Always keep your leather band
clean by wiping with a dry cloth.
111
English
Caring for Your Watch
• Wipe any dirt or moisture such as perspiration from the case and crystal with a soft cloth.
• For metallic, plastic or synthetic rubber (polyurethane) band, clean it with soap and a soft
toothbrush. Be sure to thoroughly rinse the band after cleaning to remove any soap residue.
• For a leather band, wipe off dirt using a dry cloth.
• If you will not be using your watch for an extended period of time, carefully wipe off any
perspiration, dirt or moisture and store in a proper location, avoiding locations subject to
excessively high or low temperatures and high humidity.
<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.
