●

Do not use your 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, note the

usage precautions described below. Such

types of use reduce water resistance

performance and can cause fogging of the

glass.

ー　

Do not operate the crown or buttons while

your watch is submersed in water or wet.

ー　

Avoid wearing your watch while in the

bath.

ー　

Do not wear your watch while in a heated

swimming pool, sauna, or any other high

temperature/high humidity environment.

ー　

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).

●

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.

What is a quartz movement? Verified

Watches and clocks with a quartz movement are driven by a battery. This sends an electric current through quartz crystals that will vibrate. These vibrations are passed on to the movement. Because the vibrations have a fixed frequency, watches and clocks with a quartz movement are extremely precise.

There is moisture on the inside of the glass of my Casio watch, what should I do? Verified

Casio states that if the moisture appeared after an extreme change in temperature and disappears relatively quickly afterwards, there is probably nothing wrong. If the moisture does not disappear, you should have your watch repaired as soon as possible.
