Barometric Pressure Graph Screen
The graph shows barometric readings taken
every two hours. You can use the graph to
view changes in barometric pressure over the
past 72 hours, which can be used to predict
upcoming weather.

C
A trend
Means this:
like this:
Rising barometric pressure,
which indicates that upcoming
weather probably will be fair.
Falling barometric pressure,
which indicates that upcoming
weather probably will be bad.
Note
To retrigger measurement, press (C).
●
The watch will automatically return to
●
the current time screen if you do not
perform any operation for about one
hour during barometer/temperature
measurement.
Measurement ranges are shown
●
below. [- - -] will appear for the
measured value if it is outside the
allowable range.
Barometric pressure measurement:
260 hPa to 1,100 hPa (7.65 inHg to
32.45 inHg)
Thermometer measurement: -10.0 °C
to 60.0 °C (14.0 °F to 140.0 °F)
Large changes in barometric pressure
●
and/or temperature can cause past
data readings to be plotted outside of
the visible area of the graph. Though
plots are not visible, the data is still
maintained in watch memory.

Barometric Pressure Change
Indications
Whenever the watch detects a significant
change in air pressure readings (due to
sudden altitude change, or to the passage of
a low pressure or high pressure area), it will
perform a sound and/or vibration operation
and display a flashing arrow to let you know.
The arrow that appears shows the direction of
the pressure change. These alerts are called
③
"Barometric Pressure Change Indications".
The watch will notify you by a 10-second
●
sound/vibration operation when there is a
sudden drop in atmospheric pressure.
A four-second sound/vibration operation
●
will notify you when there is a sudden rise in
atmospheric pressure, or the passage of
high or low pressure.
This
indication:
Important!
To ensure correct barometric pressure
●
change indication operation, enable it
in a location where the altitude is
constant (such as a lodge, camp area,
or on the ocean).
A change in altitude causes a change
●
in air pressure. Because of this, correct
readings are impossible. Do not take
readings while ascending or
descending a mountain, etc.

[BAROMETER INFORMATION].
6.
Press (C).

Use (A) and (D) to select a barometric
pressure change indication setting.
Enables the barometric pressure

change indication.
Disables the barometric pressure

8.
Press (C) to complete the setting
operation.
After the setting operation is complete, a
check mark appears for a few seconds,
and then the barometric pressure/
temperature setting screen re-appears.
9.
Press (E) to exit the setting screen.
Note
If the barometric pressure change
●
indication is enabled, readings are
taken every two minutes even while the
watch is performing an operation other
than barometric pressure and
temperature measurement.
The barometric pressure change
●
indication becomes disabled
automatically 24 hours after it is
enabled.
Power Saving is disabled while

barometric pressure change indication
is enabled.

The barometric pressure change

indication will become disabled
automatically when the battery
becomes [CHG] or lower.
