Crown Operations
Some water-resistant models (100 meters, 200 meters)
have a screw-in crown. When you need to perform a crown
operation, rotate it towards you to unscrew it. Then pull the
crown out. Avoid applying undue force when pulling. The watch
loses its water resistance while the crown is unscrewed. After
performing a crown operation, fully screw the crown back in.
If your watch has a rotary bezel...
You can rotate the bezel to align its ▼ mark with the
minute hand. Then you will be able to tell how much
time has elapsed since aligning the ▼ mark.

Use

Skin diving
Do not use this watch for scuba diving or other types of diving that requires air tanks.
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, do not operate its buttons or crown while it is submersed
in water or wet.
Even if a watch is water-resistant, avoid wearing it in the bath or in areas where detergents
(soap, shampoo, etc.) are being used. Such conditions can reduce water resistance.
After submersion in seawater, use plain water to rinse all salt and dirt from the watch.
To maintain water resistance, have the gaskets of your watch replaced periodically (about
once every two or three years).
A trained technician will know how to check 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.
If the fogging does not clear or if water has gotten into the watch, take it in for repair
immediately.
Continued use of the watch with water inside can result in damage to electronic and
mechanical components, the face of the watch, etc.
Your water-resistant watch has been tested in accordance with the International
Organization for Standardization regulations ISO2281 and FTC (USA) "GUIDE FOR THE
WATCH INDUSTRY." Guide 5.
Band
Tightening the band too tightly can cause you to sweat and make it diffi cult 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 fi nger.
Deterioration, rust, or corrosion of the band can cause it to break, which may result in the
watch falling off your wrist and becoming lost. Be sure to take good care of the band and
keep it clean. Should you notice any breakage, discoloration, looseness or other problem
with the band, immediately contact your original retailer or an authorized CASIO Service
Center to have it checked, repaired, or replaced. Note that you will be charged for any
repair or replacement of the band.
Temperature
Never leave the 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 the watch where it will be exposed
to very low temperatures, either. Temperature extremes can cause the watch to lose or
gain time, to stop, or otherwise malfunction.
Impact
Your watch is designed to withstand impact incurred during normal daily use and light
activity such as playing catch, tennis, etc. Dropping the 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 engaged in strenuous sports activities (motocross, etc.).

Note
Illumination remains turned on as long as L is depressed.
Illumination will turn off about four seconds after L is released.
Illumination Precautions
Illumination may be hard to see when viewed under direct sunlight.
Frequent use of illumination runs down the battery.
Semi-transparent resin parts can become discolored due to sweat and dirt, and if exposed
to high temperatures for long periods.
Contact an authorized CASIO Service Center to have resin components replaced. Note
that you will be charged for replacement costs.
Natural Leather and Imitation Leather Bands
Allowing the watch to remain in contact with other items or storing it together with other
items while it is wet for long periods can cause the color of the other items to transfer

to the natural leather or imitation leather band of the watch. Be sure to dry off the watch

thoroughly before storing it and make sure it is not in contact with other items.

Subjecting a natural leather or imitation leather band to rubbing or dirt can cause color

Metal Components
Yes
Failure to clean dirt from a metal band can lead to formation of rust, even if the band is
stainless steel or plated. If the watch is exposed to sweat or water, wipe it thoroughly with
a soft, absorbent cloth and then store it in a well-ventilated location to dry.
To clean the band, use a soft toothbrush or similar tool to scrub it with a weak solution of water
and a mild neutral detergent. Take care to avoid getting solution on the watch case.
Bacteria and Odor Resistant Band
The bacteria and odor resistant band protects against odor generated by the formation
of bacteria from sweat, which ensures good comfort and hygiene. In order to ensure
maximum bacteria and odor resistance, keep the band clean. Use an absorbent soft
cloth to wipe the band clean of dirt, sweat, and moisture. The bacteria and odor resistant
band suppresses the formation of organisms and bacteria. It does not protect against
rash due to allergic reaction, etc.
Note that CASIO COMPUTER CO., LTD. assumes no responsibility for any damage
or loss suffered by you or any third party arising through the use of this product or its
malfunction.
User Maintenance
Caring for Your Watch
A dirty or rusty case or band can soil the sleeve of your clothing, cause skin irritation,
and even interfere with watch performance. Be sure to keep the case and band clean
at all times. Rust tends to form easily after the watch is exposed to seawater and then
left without cleaning.
Sometimes a smudge like pattern may appear on the surface of a resin band. This will not
have any affect on your skin or clothing. Wipe the band with a cloth to clean it.
Keep a leather band clean by wiping it with a dry cloth. Both resin bands and leather band
can become worn and cracked over time when subjected to normal daily use.
Should your band become badly cracked or worn, be sure to have it replaced with a new
one. Request band replacement from your original retailer or an authorized CASIO Service
Center. Note that you will be charged for band replacement costs, even if your watch is
still covered by its warranty.
Remember that you wear your watch next to your skin, just like a piece of clothing. Because
of this, you should always keep your watch clean. Use a soft, absorbent cloth to wipe off
any dirt, sweat, water, or other foreign matter from the case and band.
Dangers of Poor Watch Care
Rust
Though the stainless steel used for the watch is highly rust-resistant, rust can form if the
watch is not cleaned after it becomes dirty. Failure of oxygen to come into contact with the
metal because it is dirty causes breakdown of the oxidization layer on the metal surface,
which leads to the formation of rust.
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 storing it an area subject to high moisture can
lead to premature wear, cuts, and breaks.
