H. PRECAUTIONS
CAUTION: Water-resistance performance
There are several types of
water-resistant watches, as
shown in the following table.
The unit “bar” is roughly
equal to 1 atmosphere.
* WATER RESIST (ANT) xx
bar may also be indicated
as W.R. xx bar.
For correct use within the design limits of the watch,
confirm the level of water-resistance of your watch, as
indicated on the dial and case, and consult the table.
• Water-resistance for daily use (to 3 atmospheres):
This type of watch is water-resistant to minor
exposure to water. For example, you may wear the
watch while washing your face; however, it is not
designed for use underwater.
* Upgraded water-resistance for daily use (to 5
atmospheres): This type of watch is water-resistant
to moderate exposure to water. You may wear the
watch while swimming; however, it is not designed
for use while skin diving.
* Upgraded water-resistance for daily use (to 10/20
atmospheres): This type of watch may be used for
skin diving; however, it is not designed for scuba
or saturated diving using helium gas.
* Although diver’s watches for use at depths down
to 200 metres can be used for scuba diving, they
cannot be used for saturated diving using helium
gas.
CAUTION
• Be sure to use the watch with the crown pressed
in (normal position). If your watch has a screw-type
crown, be sure to tighten the crown completely.
• Do NOT operate the crown with wet fingers or
when the watch is wet. Water may enter the watch.
If used in seawater, rinse with fresh water afterward
and wipe with a dry cloth.
• If moisture has enterd the watch, or if the inside of
the crystal is fogged up and does not become clear
within a day, immediately take the watch to your
dealer or Citzen Service Centre for repair. Leaving
the watch in such a state will allow corrosion to
form inside.
• If seawater enters the watch, place the watch in a
box or plastic bag and immediately take it in for
repair. Otherwise, pressure inside the watch will
increase, and parts (crystal, crown, buttons, etc.)
may come off.
CAUTION: Keep your watch clean.
• Leaving dust and dirt deposited between the case
and crown may result in difficulty in pulling the
crown out. Rotate the crown while in its normal
position, from time to time, to loosen dust and dirt
and then brush it off.
• Dust and dirt tend to be deposited in gaps in the
back of the case or band. Deposited dust and dirt
may cause corrosion and soil your clothing. Clean
the watch occasionally.
Cleaning the watch
• Use a soft cloth to wipe off dirt, perspiration and
water from the case and crystal.
• Use a soft, dry cloth to wipe off perspiration and
dirt from the leather band.
• To clean a metal, plastic, or rubber watchband,
wash away dirt with a mild soap and water. Use a
soft brush to remove dust and dirt jammed in the
gaps in metal band. If your watch is not water-
resistant, take it to your dealer.
NOTE: Avoid using solvents (thinner, benzine, etc.),
as they may mark the finish.
CAUTION: Operating environment
• Use the watch within the operating-temperature
range specified in the instruction manual.
Using the watch where temperatures are outside
the specified range may result in deterioration of
functions or even stoppage of the watch.
• Do NOT use the watch in places where it is
exposed to high temperature, such as in a sauna.
Doing so may result in a skin burn.
