•
Do not use your watch for scuba diving or other types of diving that requires air tanks.
OPUM-G
EN-41
• Watches that do not have WATER RESIST or WATER RESISTANT marked on
the back cover are not protected against the effects of sweat. Avoid using such
a watch under conditions where it will be exposed to large amounts of sweat or
moisture, or to direct splashing with water.
• Even if a watch is water resistant, note the usage precautions described below.
Such types of use reduce water resistance performance and can cause fogging of
the glass.
− Do not operate the crown or buttons while your watch is submersed in water or
wet.
− Avoid wearing your watch while in the bath.
− Do not wear your watch while in a heated swimming pool, sauna, or any other
high temperature/high humidity environment.
− Do not wear your watch while washing your hands or face, while doing
housework, or while performing any other task that involves soaps or detergents.
• After submersion in seawater, use plain water to rinse all salt and dirt from your
watch.
• To maintain water resistance, have the gaskets of your watch replaced periodically
(about once every two or three years).
EN-42
• A trained technician will inspect your watch for proper water resistance whenever
you have its battery replaced. Battery replacement requires the use of special tools.
Always request battery replacement from your original retailer or from an authorized
CASIO service center.
• Some water-resistant watches come with fashionable leather bands. Avoid
swimming, washing, or any other activity that causes direct exposure of a leather
band to water.
• The inside surface of the watch glass may fog when the watch is exposed to a
sudden drop in temperature. No problem is indicated if the fogging clears up
relatively quickly. Sudden and extreme temperature changes (such as coming into
an air conditioned room in the summer and standing close to an air conditioner
outlet, or leaving a heated room in the winter and allowing your watch to come into
contact with snow) can cause it to take longer for glass fogging to clear up. If glass
fogging does not clear up or if you notice moisture inside of the glass, immediately
stop using your watch and take it to your original retailer or to an authorized CASIO
service center.
• Your water-resistant watch has been tested in accordance with International
Organization for Standardization regulations.
EN-43
Band
• Tightening the band too tightly can cause you to sweat and make it difficult for air
to pass under the band, which can lead to skin irritation. Do not fasten the band too
tightly. There should be enough room between the band and your wrist so you can
insert your finger.
• Deterioration, rust, and other conditions can cause the band to break or come off
of your watch, which in turn can cause band pins to fly out of position or to fall out.
This creates the risk of your watch falling from your wrist and becoming lost, and
also creates the risk of personal injury. Always take good care of your band and
keep it clean.
• Immediately stop using a band if you even notice any of the following: loss of band
flexibility, band cracks, band discoloration, band looseness, band connecting
pin flying or falling out, or any other abnormality. Take your watch to your original
retailer or to a CASIO service center for inspection and repair (for which you will be
charged) or to have the band replaced (for which you will be charged).
EN-44
Temperature
• Never leave your watch on the dashboard of a car, near a heater, or in any other
location that is subject to very high temperatures. Do not leave your watch where
it will be exposed to very low temperatures. Temperature extremes can cause your
watch to lose or gain time, to stop, or otherwise malfunction.
• Leaving your watch in an area hotter than +60°C (140°F) for long periods can lead
to problems with its LCD. The LCD may become difficult to read at temperatures
lower than 0°C (32°F) and greater than +40°C (104°F).
Impact
• Your watch is designed to withstand impact incurred during normal daily use and
during light activity such as playing catch, tennis, etc. Dropping your watch or
otherwise subjecting it to strong impact, however, can lead to malfunction. Note
that watches with shock-resistant designs (G-SHOCK, BABY-G, G-MS) can be
worn while operating a chain saw or engaging in other activities that generate
strong vibration, or while engaging in strenuous sports activities (motocross, etc.)
EN-45
Magnetism
• The hands of analog and combination (analog-digital) watches are moved by a
motor that uses magnetic force. When such a watch is close to a device (audio
speakers, magnetic necklace, cell phone, etc.) that emits strong magnetism, the
magnetism can cause timekeeping to slow down, speed up, or stop, resulting in the
incorrect time being displayed.
• Very strong magnetism (from medical equipment, etc.) should be avoided because
it can cause malfunction of your watch and damage to electronic components.
Electrostatic Charge
• Exposure to very strong electrostatic charge can cause your watch to display
the wrong time. Very strong electrostatic charge even can damage electronic
components.
• Electrostatic charge can cause the display to go blank momentarily or cause a
rainbow effect on the display.
EN-46
Chemicals
• Do not allow your watch to come into contact with thinner, gasoline, solvents,
oils, or fats, or with any cleaners, adhesives, paints, medicines, or cosmetics that
contain such ingredients. Doing so can cause discoloration of or damage to the
resin case, resin band, leather, and other parts.
Storage
• If you do not plan to use your watch for a long time, thoroughly wipe it free of all
dirt, sweat, and moisture, and store it in a cool, dry place.
Resin Components
• Allowing your watch to remain in contact with other items or storing it together with
other items for long periods while it is wet can cause color on resin components
to transfer to the other items, or the color of the other items to transfer to the resin
components of your watch. Be sure to dry off your watch thoroughly before storing
it and make sure it is not in contact with other items.
EN-47
• Leaving your watch where it is exposed to direct sunlight (ultraviolet rays) for long
periods or failure to clean dirt from your watch for long periods can cause it to
become discolored.
• Friction caused by certain conditions (strong external force, sustained rubbing,
impact, etc.) can cause discoloration of painted components.
• If there are printed figures on the band, strong rubbing of the printed area can
cause discoloration.
• Leaving your watch wet for long periods can cause fluorescent color to fade. Wipe
the watch dry as soon as possible after it becomes wet.
• Semi-transparent resin parts can become discolored due to sweat and dirt, and if
exposed to high temperatures and humidity for long periods.
• Daily use and long-term storage of your watch can lead to deterioration, breaking,
or bending of resin components. The extent of such damage depends on usage
conditions and storage conditions.
EN-48
Leather Band
• Allowing your watch to remain in contact with other items or storing it together with
other items for long periods while it is wet can cause the color of the leather band
to transfer to the other items or the color of the other items to transfer to the leather
band. Be sure to dry off your watch thoroughly with a soft cloth before storing it
and make sure it is not in contact with other items.
• Leaving a leather band where it is exposed to direct sunlight (ultraviolet rays) for
long periods or failure to clean dirt from a leather band for long periods can cause
it to become discolored.
CAUTION: Exposing a leather band to rubbing or dirt can cause color transfer and
discoloration.
EN-49
Metal Components
• Failure to clean dirt from metal components can lead to formation of rust, even if
components are stainless steel or plated. If metal components exposed to sweat or
water, wipe thoroughly with a soft, absorbent cloth and then place the watch in a
well-ventilated location to dry.
• Use a soft toothbrush or similar tool to scrub the metal with a weak solution of
water and a mild neutral detergent, or with soapy water. Next, rinse with water
to remove all remaining detergent and then wipe dry with a soft absorbent cloth.
When washing metal components, wrap the watch case with kitchen plastic wrap
so it does not come into contact with the detergent or soap.
Bacteria and Odor Resistant Band
• The bacteria and odor resistant band protects against odor generated by the
formation of bacteria from sweat, which ensures comfort and hygiene. In order
to ensure maximum bacteria and odor resistance, keep the band clean. Use an
absorbent soft cloth to thoroughly wipe the band clean of dirt, sweat, and moisture.
A bacteria and odor resistant band suppresses the formation of organisms and
bacteria. It does not protect against rash due to allergic reaction, etc.

User Maintenance
Caring for Your Watch
Remember that you wear your watch next to your skin, just like a piece of clothing.
To ensure your watch performs at the level for which it is designed, keep it clean by
frequently wiping with a soft cloth to keep your watch and band free of dirt, sweat,
water and other foreign matter.
• Whenever your watch is exposed to sea water or mud, rinse it off with clean fresh
water.
• For a metal band or a resin band with metal parts, use a soft toothbrush or similar
tool to scrub the band with a weak solution of water and a mild neutral detergent,
or with soapy water. Next, rinse with water to remove all remaining detergent and
then wipe dry with a soft absorbent cloth. When washing the band, wrap the watch
case with kitchen plastic wrap so it does not come into contact with the detergent
or soap.
EN-52
• For a resin band, wash with water and then wipe dry with a soft cloth. Note that
sometimes a smudge like pattern may appear on the surface of a resin band. This
will not have any effect on your skin or clothing. Wipe with a cloth to remove the
smudge pattern.
• Clean water and sweat from a leather band by wiping with a soft cloth.
• Not operating a watch crown, buttons, or rotary bezel could lead to later problems
with their operation. Periodically rotate the crown and rotary bezel, and press
buttons to maintain proper operation.
Dangers of Poor Watch Care
Rust
• Though the metal steel used for your watch is highly rust-resistant, rust can form if
your watch is not cleaned after it becomes dirty.
− Dirt on your watch can make it impossible for oxygen to come into contact with
the metal, which can lead to breakdown of the oxidization layer on the metal
surface and the formation of rust.
EN-53
• Rust can cause sharp areas on metal components and can cause band pins to fly
out of position or to fall out. If you ever notice any abnormality immediately stop
using your watch and take it to your original retailer or to an authorized CASIO
service center.
• Even if the surface of the metal appears clean, sweat and rust in crevasses can
soil the sleeves of clothing, cause skin irritation, and even interfere with watch
performance.
Premature Wear
• Leaving sweat or water on a resin band or bezel, or storing your watch an area
subject to high moisture can lead to premature wear, cuts, and breaks.
Skin Irritation
• Individuals with sensitive skin or in poor physical condition may experience skin
irritation when wearing a watch. Such individuals should keep their leather band
or resin band particularly clean. Should you ever experience a rash or other skin
irritation, immediately remove your watch and contact a skin care professional.
EN-54
Battery Replacement
• Leave battery replacement up to your original retailer or authorized CASIO service
center.
• Have the battery replaced only with the type specified in the User’s Guide. Use of a
different battery type can cause malfunction.
• When replacing the battery, also request a check for proper water resistance.
• Ornamental resin components may become worn, cracked, or bent over
time when subjected to normal daily use. Note that if cracking or any other
abnormality indicating possible damage is noticed in a watch submitted for battery
replacement, your watch will be returned with an explanation of the abnormality,
without the requested servicing being performed.
EN-55
Initial Battery
• The battery that comes loaded in your watch when you purchase it is used for
function and performance testing at the factory.
• The test battery may go dead quicker than the normally rated battery life as noted
in the User’s Guide. Note that you will be charged for replacement of this battery,
even if replacement is required within your watch’s warranty period.
Low Battery Power
• Low battery power is indicated by large timekeeping error, by dim display contents,
or by a blank display.
• Operation while battery power is low can result in malfunction. Replace the battery
as soon as possible.
