Auto Altitude Data Recording
The altitude data described below is recorded
automatically while the watch is in the
Altimeter Mode. One record each is
maintained in memory for each of these items.

* Cumulative ascent and cumulative descent
values are updated whenever there is a
difference of at least ±15 m (±49 feet) from
one reading to the next.
Note
●
Auto recording ends when you exit the
Altimeter Mode. Re-entering the
Altimeter Mode restarts recording of
cumulative values from where it was
stopped when you last exited the
Altimeter Mode.
●
Auto measurement continues if you go
from the Altimeter Mode to another
mode while Mission Log is enabled.
●
Every time an auto measurement
operation is performed while Mission
Log is enabled, the watch checks the
currently saved values of the following
data items and updates them as
required: MAX, MIN, ASC, DSC.

[ERR] will appear on the display if
connection fails for some reason.
Specifying the Altitude
Measurement Unit
You can select either meters (m) or feet (ft) as
the Altimeter Mode display unit.
Important!
●
When Tokyo (TYO) is set as the Home
City, the altitude unit is fixed as meters
(m) and cannot be changed.
1. Enter the Timekeeping Mode.

2. Loosen the crown and then pull it out.
The currently selected Home City will
appear on the display.
3. Press (B) seven times.
This causes [UNIT] to appear, with [m] or
[ft] flashing.
4. Rotate the crown to select an altitude unit.
[m]: Meters
[ft]: Feet
5. Push the crown back in and then lock it.
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.
Altitude Reading
Precautions
Effects of Temperature
When taking altitude readings, take the steps
below to keep the watch at as stable a
temperature as possible. Changes in
temperature can affect altitude readings.
●
Take readings with the watch on your wrist.
●
Take readings in an area where
temperature is stable.
Altitude Readings
●
Do not use this watch while skydiving, hang
gliding, paragliding, gyrocopter flying, glider
flying, or engaged in other activities where
altitude changes suddenly.
●
Altitude readings produced by this watch
are not intended for special-purpose or
industrial level use.
●
In an aircraft, the watch measures the in-
cabin pressurized air pressure, so readings
will not match altitudes announced by the
crew.
Altitude Readings (Relative Altitude)
This watch uses International Standard
Atmosphere (ISA) relative altitude data
defined by the International Civil Aviation
Organization (ICAO). Barometric pressure
generally becomes lower as altitude
increases.
Correct measurement may not be possible
under the conditions below.
●
During unstable atmospheric conditions
●
During sudden temperature changes
●
After the watch has been subjected to
strong impact
