6. EL Light
<What is EL>
It is called electro-luminescence. It is a scientific phenomenon which becomes
illuminant when voltage is applied to it. This watch utilizes a luminiferous method
by making EL substance a panel.
<How to Light the Illumination>
The EL illumination comes on in the following situations.
(1) When button (A) is pressed (or kept pressing) in Normal Time Display or
Normal Calendar Display.
(2) When operating to display split time or stop in the Chronograph counting.
(3) When button (B) is pressed (or kept pressing) while Timer is running.
<Switching the Mode During Timer Running>
Even if button (M) is pressed and the mode is changed while Timer is running, the
timer countdown will continue. When you return to the Timer Mode, the
countdown time is again displayed. However, the watch will return to the initial
set time when the set time of the timer has finished counting down.
8. All-Reset Function
(1) Pull the crown out.
(2) Press the three buttons (A), (B) and (M) simultaneously. (While pressed, there
will be no display.)
(3) Release the buttons. (All the display segments will appear.)
(4) Push the crown in. (At this point, a monitor sound is heard.)

7. When These Problems Occur
<The Watch Shows Abnormal Display>
When the battery life is close to expiring, the display or functions may become
abnormal. When these problems occur, replace the battery as soon as possible. In
rare cases, a strong impact etc. may cause the display or functions to become
abnormal (no display, alarm sounds incessantly etc.). In this case, perform the allreset operation by referring to “8. All-Reset Function”.
<Following Battery Replacement>
After the battery has been replaced, perform the all-reset operation by referring to
“8. All-Reset Function”.

Dial Case (Case back)
Specification
For correct use within the design limits of the watch, confirm the level of waterresistance of your watch, as indicated on the dial and case, and consult the table.
9. Precautions
WARNING: 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.
26 27
• Water-resistance for daily use (to 3 atmospheres): This type of watch is waterresistant 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.
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 or button with wet fingers or when the watch is wet.
Water may enter the watch and compromise water-resistance.
• If the watch is used in seawater, rinse with fresh water afterward and wipe with
a dry cloth.
• If moisture has entered 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 Citizen Service Center 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.
28 29
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 mild soap
and water. Use a soft brush to remove dust and dirt jammed in the gaps in the
metal band. If your watch is not water-resistant, take it to your dealer.
NOTE: Avoid using solvents (thinner, benzine, etc.), as they may damage the finish.
WARNING: Handling of the battery
• Keep the battery out of the reach of small children. If a child swallows the
battery, contact a physician immediately.
CAUTION: Replacing the battery
• For replacement of the battery, take your watch to your dealer or Citizen Service
Center.
• Replace the battery as soon as possible if the service life of the battery has
expired. Leaving a depleted battery in the watch may result in leakage, which
can damage the watch severely.
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.
• Do NOT leave the watch in a place where it is exposed to high temperature,
such as the glove compartment or dash-board of a car.
Doing so may result in deterioration of the watch, such as deformation of plastic
parts.
• Do NOT place the watch close to a magnet.
Timekeeping will become inaccurate if you place the watch close to magnetic
health equipment such as a magnetic necklace or a magnetic latch of a
refrigerator door or handbag clasp or the earphone of a mobile phone. If this has
occurred, move the watch away from the magnet and reset the time.

32
8: Battery Life: Approx. 2 years (based on assumed use of 20-seconds alarm
sound/day, 5-seconds timer time-up sound/day, 3-seconds El light
function/day)
* A new battery should be able to support stable accuracy for
approximately 2 years when used under normal circumstances
(conditions described before). However, battery life will differ
with the conditions of use of the alarm, chronograph, El light
etc.
* These specifications are subject to change for product improvement without
prior notice.
