 Eco-Drive (solar powered) watch handling precautions
<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 optimal operation.

84
 Eco-Drive (solar-powered) 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 (19-11/16 inch) 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.

85
 Eco-Drive (solar-powered) watch handling precautions
<Replacement of Rechargeable Cell>
• This watch utilizes a special rechargeable cell that does not require regular 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. For optimal performance, we recommend having your watch inspected
(chargeable to the owner) by an Authorized Service center to ensure operation is within factory
specifications.

WARNING Handling of Rechargeable Cell

• 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.

86
 Eco-Drive (solar-powered) watch handling precautions

WARNING 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 silver 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.

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 Customer Support Center for inspection and/or repair.

CAUTION Precautions (continued)

• 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.

CAUTION When Wearing Your Watch

<Band>
• Leather, genuine skin and rubber (urethane) bands will deteriorate over time due to
perspiration, body oils and dirt. Be sure 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.
• 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.

92
 Precautionary items and usage limitations
• 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.
• 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 do not recommend attempting to adjust the watch band yourself. Special expertise and
experience is required for proper adjustment. If not adjusted correctly, the band may become
detached leading to loss of your watch. (Some retailers may supply a band adjustment tool with
your purchase).
For band adjustment, we recommend you consult the retailer from where the watch was
purchased or your nearest Authorized Citizen Service Center. Some repair shops may charge a
nominal fee for adjustment if the watch was not purchased directly from them.
<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 on pages 98 and 99.

93
 Precautionary items and usage limitations
<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.
<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.

94
 Precautionary items and usage limitations
<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.

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 in the same manner as
undergarments. Corrosion of the metal or unnoticed soiling such as that caused by perspiration
and dirt can soil sleeves and other portions of clothing. Keep your watch clean at all times.
• The case and band of the watch come into direct contact with the skin. If you think there is
something wrong, discontinue wearing the watch immediately and consult your physician.
In the case of accumulation of sweat or dirt on a metal band or case, clean thoroughly using
a brush and neutral detergent. In the case of a leather or rubber (urethane) band, wipe clean
using a dry cloth.
• Leather bands may become discolored by perspiration or dirt. Always keep your leather band
clean by wiping with a dry cloth.

95
 Precautionary items and usage limitations
Caring for Your Watch
• Wipe any dirt or moisture such as perspiration from the case and crystal with a soft cloth.
• For a metallic, plastic or rubber (urethane) watchband, wash any dirt off with water.
Remove the small amounts of dirt trapped between the crevices of the metallic band with a
soft brush.
• 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 gradually becomes weaker 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.
