9. THERMOMETER
A. Methods of measurement
As described below, there are two methods of measuring temperature.
The most recently measured temperature is displayed in the Time mode
(approximate temperature is graphically displayed in both the “time display” and
the “city selection display”) and in the Timer mode. Also, switching between
Celsius display (°C) and Fahrenheit (°F) display is possible.
<Automatic temperature measurement>
Temperature is automatically measured every hour on the hour, with the
temperature display then being updated. However, measurement will not be
carried out if the Chronograph mode or Time/Calendar mode is in the
adjustment mode (blinking display) at measurement time.
<Temperature measurement by button operation>
If you change to the “calendar, temperature display” in the Time/Calendar mode,
the temperature will be measured at 2-second intervals for 2 minutes.
2524
<Changing the mode during time measurement in chronograph mode>
Even if button M is pressed during a time measurement in chronograph mode
and mode is changed, time measurement is continued internally. The measured
time is shown when the mode is returned to chronograph again. However, if the
time measurement is continued for more than 24 hours, the chronograph stops
at the reset state.
* Confirmation sound and EL light
At the time of start, stop, split time check or reset operation in chronograph
mode, a confirmation sound is heard.
At the time of stop or a split time measurement, the EL light is turned on with
the sound.

C. Switching between Celsius/Fahrenheit display
In the Time mode’s “Date, calendar display,” by
pressing button M for more than 2 seconds while
button A is pressed, the temperature display will
switch from Celsius (°C) to Fahrenheit (°F) or vice
versa.
If button M is pressed first, however, the display will
not change.
<About the graphic display of approximate temperature>
Approximate temperature is graphically displayed in the Time mode’s “time
display” and “city selection display.”
The graphic display always shows Celsius temperature, even when the
numerical display has been set to Fahrenheit.

(Notes)
• If the watch is worn on the wrist durning temperature measurement, the body
temperature affects measurement.
For accurate temperature measurement, take the watch off and leave it in the
measuring environment at least for 20 to 30 minutes.The influence of body
temperature depends on environmental conditions such as difference between
atmospheric temperature and body temperature before taking the watch off,
etc.
• Do not use the thermometer out of the display range. Extremely hot or cold
temperature may cause malfunction of the watch.

11. ALL RESET
After replacement of the battery, be sure to perform the all reset operation as
shown below.
If the watch malfunctions or shows an abnormal display as a result of an
excessive shock or static electricity (for example, the watch indicates nothing,
continuously sounds alarm, etc.). Perform the all reset operation.
(1) Pull the crown out.
(2) Simultaneously press buttons A, B and M.
(3) Release the three buttons.
(4) Press the crown back. (A confirmation sound
is heard.)
All reset operation is complete.
Before use, reset the watch for the correct time
in all modes.
29
10. LOW BATTERY INDICATOR
When the battery gets weak, the low battery indicator function appears in the
display as shown below.
• The second hand moves at 2-second intervals (moves by 2 increments every 2
seconds).
• The temperature display starts to blink “- - -” continuously.
Even when the watch falls into such condition, it
still displays the time but the EL light,
thermometer and alarm will not function.
Immediately replace the battery with new one.

12. PRECAUTIONS
CAUTION:Water-resistance performance
There are several types of water-resistant watches, as
shown in the following table. 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.

(The unit “bar” is roughly equal to 1 atmosphere.)
* WATER RESIST(ANT) xx bar may also be indicated as W.R. xx bar.
• 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 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.
33
•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 buttons 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.

•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.
