I. PRECAUTIONS
Water Resistance

• To prevent water coming into contact with the

internal mechanism of the watch, the crown should
under no circumstances be pulled out while the
watch is wet.

• If watches designed for sports or working in the

water are exposed to salt water or significant
amounts of sweat, they should be rinsed in fresh
water and dried thoroughly.

• Exposure to water may affect the durability of

some types of leather bands.

• Because the internal watch parts may hold some

moisture, if the external temperature is lower than
that inside the watch, the glass covering the watch
face may fog up.
If this fogging up is only temporary it poses no
problem, however, if it persists over a long period
of time you should discuss the matter with a
salesperson at the shop where you purchased the
watch or at a Citizen Service Centre.

Temperature
Avoid exposing the watch to direct sunlight or
leaving it in extremely hot or cold locations for a
long period of time.
• This will cause malfunctioning and shorten the life

of the battery.

• This may cause your watch to gain or lose time

and affect its other functions.

Shock
• This watch will withstand the bumps and jars

normally incurred in daily use and while playing
such non-contact sports as golf and catchball.

• Dropping the watch on the floor or otherwise

imparting severe shock to it may cause
malfunctioning or damage.

Static Electricity
• The integrated circuits used in the watch are

sensitive to static electricity. If exposed to intense
static electricity, the watch’s display may lose its
accuracy.

Chemicals and Gases
Avoid wearing the watch in the presence of strong
chemicals or gases. If the watch comes in contact
with such solvents as thinner and benzine or
products containing materials such as gasoline, nail
polish, detergent or adhesive, its components may
discolour,,dissolve or crack. Be especially careful to
avoid chemicals. The watchcase or band may
discolour if they come in contact with mercury from
a broken thermometer or the equipment.

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.

Battery
• The battery is a monitor battery that has been

factory-installed. For this reason it may wear out
after purchase before the specified battery life
(about 3 years) has elapsed.

• Be sure to keep the battery out of the reach of

infants and small children. Should accidental
ingestion occur, consult a doctor immediately.
