the digital display to be recalled and used only when necessary , and a function that makes
it possible to easily call up the time and date of 30 cities around the world as well as UTC
(Universal Time Coordinated) time and date simply by pressing the watch buttons.
It is also equipped with an EL illumination function that enables the display to be viewed
in the dark.

status as well as the use of daylight savings time for each of the 30 cities and UTC
(Universal Time Coordinated) displayed by the watch.

[Alarm]

* When none of the buttons are operated for about 2 minutes in the time, calendar,

alarm or zone setting mode, the watch returns to the shutter mode.

* When none of the buttons are operated for about 10 minutes in the chronograph

or timer mode (excluding when timing is in progress), the watch returns to the

<Hint for Setting the Time Accurately>

If the second hand is stopped at the 0 seconds position, the minute is advanced 4-5
minutes past the correct time and then turned back to the correct time, and the crown is
pushed in when the digital time is at 0 seconds, the watch can be accurately set to the
correct time.

alarm time.

* After the alarm has been set, the alarm time does not change even if the time

mode is set to daylight savings time.

10. Using the Chronograph

The chronograph is able to measure and display time up to a maximum of 23 hours, 59
minutes and 59.99 seconds in 1/100 second units. Following completion of measure­ment for 24 hours, the chronograph returns to the reset display and stops. In addition, the
chronograph is also able to measure split time (intermediate elapsed time).

* When none of the buttons are operated for about 2 minutes in the alarm correc-

tion state, the watch automatically returns to the normal alarm display.

* When button (M) is pressed in the alarm correction state, the watch immediately

returns to the normal alarm display.

and UTC (Universal Time Coordinated)
displayed by this watch to either be set to
displayed or not displayed, and to set daylight
savings time for each city except for UTC. Only
those cities for which the city display has been
set (On) are displayed in the time, calendar and
alarm modes.

<Setting Procedure>

(1) Press button (M) to switch the watch to the zone

setting mode.

* When desiring to set another city, pressing button (B) again switches the watch to

the correction state of the next city. Set display or non-display and the use of
daylight savings time for each city by repeating the same procedure in the order
described above.

(7) When settings have been completed for each city, press button (M) to return to the

normal display.

13. All-Reset Procedure

Always make sure to perform the all-reset procedure described below after replacing the
battery. The display or operation of the watch may rarely become abnormal (such as the
display not being shown or the alarm continuing to sound) when the watch is subjected
to a strong impact or static electricity. Perform the following all-reset procedure in these
cases as well.

<All-Reset Procedure>

* When none of the buttons are operated for about 2 minutes in the zone setting

correction state, the watch automatically returns to the normal display.

* Pressing button (M) in the zone setting correction state immediately returns the

watch to the normal zone setting display.

After performing the all-reset procedure, correctly
reset the time and other modes before using the
watch.

14. Precautions CAUTION:

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.

Water-resistance performance

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.

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.

30 31

• 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:

• 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.

Keep your watch clean.

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 mar the finish.

WARNING:

• Keep the battery out of the reach of small children. If a child swallows the battery,
contact a physician immediately.

CAUTION:

• 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:

• 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.

32 33

Handling of the battery

Replacing the battery

Operating environment

• 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.

• Do NOT place the watch close to household appliances that generate static electricity.
Timekeeping may become inaccurate if the watch is exposed to strong static electricity,
such as is emitted from a TV screen.

• Do NOT subject the watch to a strong shock such as dropping it onto a hard floor.

• Avoid using the watch in an environment where it may be exposed to chemicals or
corrosive gases.
If solvents, such as thinner and benzine, or substances containing such solvents come
in contact with the watch, discoloration, melting, cracking, etc. may result. If the watch
comes in contact with mercury used in thermometers, the case, band or other parts may
become discolored.
