9. PRECAUTIONS
CAUTION: Water-resistance performance
There are several types of water-resistant watches,
as shown in the following table. For correct use
within the design limits of the watch, confirm the
level of water-resistance of your watch, as indicated
on the dial and case, and consult the table.
Water-resistance for daily use (up to 3
atmospheres): This type of watch is water-
resistant to minor exposure to water. For example,
you may wear the watch while washing your face;
however, it is not designed for use under water.
Upgraded water-resistance for daily use ( up to
5 atmospheres): This type of watch is water-
resistant to moderate exposure to water. You wear
the watch while swimming; however, it is not
designed for use while skin diving.
Upgraded water-resistance for daily use ( up to
10/20 atmospheres): This type of watch may be
used for skindiving; however, it is not designed for
scuba or saturated diving using helium gas.
CAUTION
• Do NOT operate the button with wet fingers or
when the watch is wet. Water may enter the
watch and compromise water-resistance.
• If the watch is used in seawater, rinse with fresh
water afterward and wipe with a dry cloth.
• If moisture has entered the watch, or if the inside
of the crystal is fogged up and does not become
clear within a day, immediately take the watch to
your dealer or Citizen Service Centre for repair.
Leaving the watch in such a state will allow
corrosion to form inside.
• 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, buttons, etc.) may
come off.
CAUTION: Keep Your Watch Clean
Wipe off soil and moisture from the glass with a
soft, absorbent cloth. If you wear the watch when
the back side of the case and watchband is soiled
they may cause a skin rash as they come in direct
contact with your skin. Keep your watch clean also
to avoid staining your cuffs.
Clean the Watch
• Use a soft cloth to wipe off dirt, perspiration and
water from the case and crystal.
• Use a soft, dry cloth to wipe off perspiration and
dirt from the leather band.
• To clean a metal, plastic, or rubber watchband,
wash away dirt with mild soap and water. Use a
soft brush to remove dust and dirt jammed in the
gaps in the metal band. If your watch is not waterresistant, take it to your dealer.
NOTE: Avoid using solvents (thinner, benzine, etc.)
as they may mar the finish.
WARNING: Handling of the battery
• Keep the battery out of reach of small children.
If a child swallows the battery, contact a physician
immediately.
CAUTION: Replacing the battery
• For replacement of the battery, take your watch to
your dealer or Citizen Service Centre.
• Replace the battery as soon as possible if the
service life of the battery has expired. Leaving a
depleted battery in the watch may result in
leakage, which can damage the watch severely.

CAUTION: Operating environment
• Use the watch within the operating-temperature
range specified in the instruction manual.
Using the watch where temperatures are outside
the specified range may result in deterioration of
functions or even stoppage of the watch.
• Do NOT use the watch in places where it is
exposed to high temperature, such as in a sauna.
Doing so may result in a skin burn.
• Do NOT leave the watch in a place where it is
exposed to high temperatures, such as the glove
compartment or dash-board of a car.
Doing so may result in deterioration of the watch,
such as deformation of plastic parts.
• Do NOT place the watch close to a magnet.
Timekeeping will become inaccurate if you place
the watch close to magnetic health equipment
such as a magnetic necklace or a magnetic latch
of a refrigerator door or handbag clasp or the
earphone of a mobile phone. If this has occurred
move the watch away from the magnet and reset
the time.
• Do NOT place the watch close to household
appliances that generate static electricity.
Timekeeping may become inaccurate if the watch
is exposed to strong static electricity, such as is
emitted from a TV screen.
• Do NOT subject the watch to a strong shock
such as dropping it onto a hard floor.
• Avoid using the watch in an environment where it
may be exposed to chemicals or corrosive gases.
If solvents, such as thinner and benzine, or
substances containing such solvents come in
contact with the watch, discolouration, melting,
cracking, etc., may result. If the watch comes in
contact with mercury used in thermometers, the
case, band or other parts may become
discoloured.
