Your watch may differ somewhat from the one shown in the illustration.
Some models may use a combination of hands and rotating disks to indicate
information. The word "hand" in this section is used to mean both analog hands
and rotating disks.

Note
Take care that you set the correct AM
or PM time.
When changing the time, move the
minute hand four or fi ve minutes past
your fi nal setting, and then back it up
to the setting you want.
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.

on the back cover.

of Daily
Use
Windsurfi ng
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.

Metal Components
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

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.
