Manual

●

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.)

●

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.

●

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.

●

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.

●

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.

●

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.

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.
