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
month.
• Do not leave it in dark places for long periods of time.
Charging your watch
45
Charging your watch
CAUTION
• 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.

About signal reception
There are three ways to receive the time signal.
Reception method Explanation
Automatic reception
The watch receives time signals automatically every night.
On demand reception
You can perform signal reception manually when required.
(page
29
)
Recovery automatic
reception
The watch automatically receives time signals when it is charged
enough after it stopped due to insufficient charge.
• Even when this watch receives the signal successfully, the accuracy of the
displayed time will be dependent on the reception environment and internal
processing.
• This watch keeps ±15-second monthly accuracy even if no time signal is received.
Continued on the next page
➡
50
About signal reception
When receiving the time signal
Remove the watch and place it on a stable surface
where it can receive the signal better, such as next
to a window.
• When wire glass is used for the window, open it
or change the reception place.
• The reception antenna is located at the 7:00
position of the watch.
Place the watch with the 7:00
position facing toward the station.
• Do not move the watch during time signal
reception.
• When the second hand is moving once every two
seconds (during insufficient charge warning),
time signal reception is not executed. Charge the
watch before trying reception.

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.
71
Eco-Drive watch handling precautions
CAUTION
Recharging Precautions
• Do not charge the watch at a high temperature (about
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.
72
Eco-Drive watch handling precautions
<Replacement of Rechargeable Cell>
• This watch utilizes a special rechargeable cell that does not require periodical replacement.

• 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.
77
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.
78
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.
79
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.
80
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.
81
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.
82
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.
83
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.
