Checking the Current
Temperature
1. Enter the Thermometer Mode.
l
Navigating Between Modes
Entering the Thermometer Mode will start
temperature measurement and display
the result.
●
After you enter the Thermometer Mode,
the watch takes readings about every
five seconds for three minutes. After
that, a measurement is taken about
every two minutes.
●
To retrigger measurement, press (A).
Temperature
Note
●
If the hour and/or minute hand is
located over the digital display when
you perform a temperature
measurement, the hands will
temporarily shift to the 22-second or
38-second position to allow easier
reading of measurement values. The
hands will unshift to their normal
positions after about three seconds.
●
The watch will automatically return to
the Timekeeping Mode if you do not
perform any operation in the
Thermometer Mode for about one
hour.
●
The measuring range is -10.0 °C to
60.0 °C (14.0 °F to 140.0 °F) (0.1 °C
(0.2 °F) units). [- - .-] will appear for the
measured value if it is outside the
allowable range.
●
To return to the Timekeeping Mode,
hold down (B) for at least two seconds.
Calibrating Temperature
Readings (Offset)
The watch’s temperature sensor is adjusted at
the factory and normally does not require
calibration. However, you can calibrate the
displayed value if you notice major errors in
readings.
Important!
●
Check to make sure that the value you
use for calibration produces correct
temperature readings.
●
Before calibrating the temperature
reading, remove the watch from your
wrist and leave it in the area where you
plan to measure temperature for about
20 or 30 minutes to allow the case
temperature to become the same as
the air temperature.
1. Enter the Thermometer Mode.

If you do not perform any operation for
about two minutes after pulling out the

automatically become disabled. If that
happens, push the crown back in and
then pull it out again.
Specifying the Temperature
