2.
Hold down (D) for at least two seconds.
If this turns on barometric pressure
change indication, [INFO ON] will stop

appear on the display.
3.
To disable barometric pressure change
indication, hold down (D) again for at least
two seconds.
Note
If Barometric Pressure Change
●
Indications are on, barometric
pressure readings are taken every two

The Barometric Pressure Change
●
Indication becomes disabled
automatically 24 hours after it is
enabled.
You will not be able to turn on
●
barometric pressure change indication
if the watch's battery level is low.
Low battery power will also cause

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.

2.
Pull out the crown.
This displays the current barometric
pressure and enters the Barometric
Pressure Offset Mode.
3.
Rotate the crown to change the value.
Setting range: 260 to 1,100 hPa (or 7.65
inHg to 32.45 inHg)
Setting unit: 1 hPa (or 0.05 inHg)
To return the barometric pressure
●
setting to its initial factory default, press
(A) and (C) at the same time.
4.
Push the crown back in to complete the
setting operation.
Note
If you do not perform any operation for
●
about two minutes after pulling out the
crown, crown operations will
automatically become disabled. If that
happens, push the crown back in and
then pull it out again.
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 (TYO) is the Home City,
●
the barometric pressure unit is fixed as
hectopascals (hPa) and cannot be
changed.
