Calibrating Barometric
Pressure Readings (Offset)
The watch’s pressure 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!
●
The watch will not be able to produce
correct barometric pressure readings if
you make a mistake during the
calibration procedure. Check to make
sure that the value you use for
calibration produces correct pressure
readings.
1. Enter the Barometer Mode.

2. Hold down (D) for at least two seconds.
Release the button when [SET] starts to
flash and then disappears from the
display.
This displays the current barometric
pressure and enters the Barometric
Pressure Offset Mode.
3. Use (A) and (C) to change the value.
Setting range: 260 to 1,100 hPa
Setting unit: 1 hPa
●
To return the barometric pressure
setting to its initial factory default, press
(A) and (C) at the same time.
4. Press (D) to exit the setting screen.
Specifying the Barometric
Pressure Unit
You can specify either hectopascals (hPa) or
inches of mercury (inHg) as the display unit for
barometric pressure values.
Important!
●
When Tokyo (TOKYO) is the Home
City, the altitude unit is fixed as
hectopascals (hPa) and cannot be
changed.
1. Enter the Timekeeping Mode.

2. Hold down (D) for at least two seconds.
Release the button when the name of the
currently selected Home City appears on
the display.
Example: When your Home City is Los
Angeles
Home City
3. Press (E) eight times.
This causes [UNIT] to appear, with [hPa]
or [inHg] flashing.
4. Press (A) to toggle between barometric
pressure units.
[hPa]: Hectopascals
[inHg]: Inches of mercury

5. Press (D) twice to exit the setting screen.
Barometric Pressure
Reading Precautions
●
The barometric pressure graph produced
by this watch can be used to obtain an idea
of upcoming weather conditions. However,
this watch should not be used in place of
precision instruments required for official
weather prediction and reporting.
●
Pressure sensor readings can be affected
by sudden changes in temperature.
Because of this, there may be some error in
the readings produced by the watch.
Temperature
Measurement
The watch can be used to take current air
temperature readings.
Important!
●
Check the information at the link below
to find out how to ensure correct
readings.

Checking the Current
Temperature
1. Enter the Temperature Mode.
l
Navigating Between Modes
Entering the Temperature Mode will start
temperature measurement and display
the result.
●
After you enter the Temperature 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).
Note
●
The watch will automatically return to
the Timekeeping Mode if you do not
perform any operation in the
Temperature 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 (E) for at least two seconds.
