Configuring Current Time and Date Settings
You can use the procedure below to adjust the Timekeeping Mode time and date settings if they are off.
Changing the digital Home City data should cause the analog time setting to change accordingly. If the
analog time does not indicate the digital time, check the home positions of the hands and make
adjustments if necessary (page E-19).
To change the current time and date settings
1. In the Timekeeping Mode, hold down A until ADJ appears in the
lower display.
When you release A (after ADJ appears), SET will be flashing in
•
the upper display.

Note
•
While the 12-hour format is selected for timekeeping, a P (PM) indicator will appear for times from
noon to 11:59 p.m. No indicator appears for times from midnight to 11:59 a.m. With 24-hour format,
time is displayed from 0:00 to 23:59, without any P (PM) indicator.
•
The watch's built-in full automatic calendar makes allowances for different month lengths and leap
years. Once you set the date, there should be no reason to change it except after you have the
watch's batteries replaced.
•
The day of the week changes automatically when the date changes.

•
The dial hand must point to 12 o'clock.
•
The watch will return to regular timekeeping automatically if you do not perform any operation for
about two or three minutes. Any changes you have made to settings up to that point will be saved.
2. Use D (+) and B (–) to adjust the position of the currently selected hand.
•
Holding down either button will cause the hand to move at high speed. Once started, high-speed
hand movement will continue even if you release the button. To stop high-speed hand movement,
press any button.
•
The second hand and dial hand will automatically stop high-speed movement after they complete
one revolution. The minute hand will stop automatically after 12 revolutions.
3. Press A to exit home position correction and return to regular timekeeping.
Note
•
After performing home position adjustment, enter the Timekeeping Mode and check to make sure that
the analog hands and the upper display indicate the same time. If they do not, perform home position
adjustment again.

Temperature
Temperature
•
Temperature is displayed in units of 0.1°C (or 0.2°F).
•
The displayed temperature value changes to - - - °C (or °F) if a
measured temperature falls outside the range of –10.0°C to 60.0°C
(14.0°F to 140.0°F). The temperature value will reappear as soon as
the measured temperature is within the allowable range.
Display Units
You can select either Celsius (°C) or Fahrenheit (°F) for the displayed temperature value. See "To specify
the temperature unit" (page E-24).
Temperature Sensor Calibration
The temperature sensor built into the watch is calibrated at the factory and normally require no further
adjustment. If you notice serious errors in the temperature readings produced by the watch, you can
calibrate the sensor to correct the errors.
Important!
•
Incorrectly calibrating the temperature sensor can result in incorrect readings.
Carefully read the following before doing anything.
– Compare the readings produced by the watch with those of another reliable and accurate thermometer.
– If adjustment is required, remove the watch from your wrist and wait for 20 or 30 minutes to give the
temperature of the watch time to stabilize.

The following steps explain how to configure timekeeping settings only.
3. When the timekeeping setting you want to change is flashing, use D and/or B to change it as
described below.

To do this:
Toggle between 12-hour (12H) and 24-hour (24H)
timekeeping.
Reset the seconds to 00
(If the current seconds count is between 30 and 59,
one is added to the minute count).

4. After all of the settings are the way you want, press A to exit the setting screen.
Hand Home Position Adjustment
Strong magnetism or impact can cause the hands of the watch to go out of alignment.
•
Home position adjustment is not necessary when the analog time and digital time are the same time in
the Timekeeping Mode.
To adjust home positions
1. In the Timekeeping Mode, hold down A and keep it depressed for
about five seconds until H.SET appears on the lower display.
When you release A after H.SET appears, the second hand will
•
move to 12 o'clock. This indicates the second hand home position
adjustment mode.
•
Though ADJ will appear in the lower display about two seconds
after you hold down A, do not release the button yet. Keep it
depressed until H.SET appears.
Use the C button to select a hand for adjustment. Each press of
•
C cycles in sequences from the second hand, to the hour and

minute hands, and then the dial hand. Selecting a hand causes it to
move to 12 o'clock and the content of the upper display changes as
shown in the table below.

Taking Temperature Readings
This watch uses a temperature sensor to measure temperature.
To take temperature readings
Temperature
1. While in the Timekeeping Mode, press D to enter the Thermometer
Mode.
•
TEMP will appear in the lower display and temperature
measurement will start. After about one second, the measurement
reading will appear in the upper display.
•
The watch will continue to take temperature readings every five
seconds for one or two minutes.
2. Press D to return to the Timekeeping Mode.
•
The watch will return to the Timekeeping Mode automatically if you
do not perform any operation for about one or two minutes after
entering the Thermometer Mode.
To calibrate the temperature sensor
1. Take a reading with another measurement device to determine the
exact current temperature.
2. With the watch in the Timekeeping Mode, press D to enter the
Thermometer Mode.
3. Hold down A for about two seconds until the temperature reading
disappears from the upper display. Release A at this time, which will
cause the temperature reading to flash, which indicates the setting
mode.
4. Use D (+) and B (–) to calibrate the temperature value with the reading of another instrument.
•
Each press of a button changes the temperature value in units of 0.1°C (0.2°F).
To return the currently flashing value to its initial factory default setting, press D and B at the same
•
time.
5. Press A to return to the Thermometer Mode.
Thermometer Precautions
Temperature measurements are affected by your body temperature (while you are wearing the watch),
direct sunlight, and moisture. To achieve a more accurate temperature measurement, remove the watch
from your wrist, place it in a well ventilated location out of direct sunlight, and wipe all moisture from the
case. It takes approximately 20 to 30 minutes for the case of the watch to reach the actual surrounding
temperature.
