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 thorougly.
• 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 watchface
may fog up. If this fogging up is only temporary it
causes 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 a 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, etc.
• Dropping the watch on the floor or otherwise
imparting severe shock to it may cause
malfuctioning or damage.
Magnetic Fields
This watch is antimagnetic up to 60 gauss and not
affected by the magnetic fields produced by ordinary
household electric appliances. If used in the immediate
vicinity of strong magnetism, however, the watch's
functions may temporarily be affected.

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 and gases. If the watch comes in contact
with such solvents as thinner and benzine or products
containing materials such as gasoline, polish,
detergent or adhesive, its components may discolor,
dissolve or crack. Be especially careful to avoid
chemicals. The watchcase or band may discolor if
they come in contact with mercury from a broken
thermometer or other 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
backside 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. How to clean the watchband:
• Metal band: Wash soiled parts with a tooth brush in
mild, soapy water.
• Plastic and Rubber band: Wash in water. Do not
use solvent.
• Leather band: Rub lightly on the front side with a
soft, dry cloth. Use a cloth moisturised with alcohol
to clean the underside.
Periodic Inspection
Getting your watch checked once every year or two
is recommended to ensure long use and trouble-free
operation.
Be sure to keep the batteries out of reach of
infants and small children. Should accidental
ingestion occur, consult a doctor at once.
• Refer to tha diagram on "water resistance".
