Current Session Record
The Current Session Record contains the data described below. The contents
of this record are updated at regular intervals while a save session is in
progress.
• The maximum total ascent and total descent value is 99,995 meters
(or 99,980 feet). Each value reverts to zero after the maximum is reached.
How current session record data is updated
Note
• The following operation is performed simultaneously with the operation
described under “How periodic records are created and saved”.
Data
High Altitude
Low Altitude
Total Ascent

Description
Highest altitude reached during the current session.
Lowest altitude reached during the current session.
Total cumulative ascent during the current session.
Total cumulative descent during the current session.
Relative change in altitude during the current session.
1. When you hold down C to start a save session, the watch clears any data
that is already stored in the current session record.
2. The watch measures altitude and calculates data every five seconds for
the first three minutes, and updates current record data accordingly.
3. After three minutes, the watch measures altitude and calculates data every
two minutes, and updates current record data accordingly.
Historical Record
The Historical Record keeps track of high altitude, low altitude, total ascent,
and total descent values across multiple save sessions. The contents of this
record are updated at the end of each session.
Data
High Altitude
Low Altitude
Total Ascent
Total Descent
Description
Highest altitude reached during all of the sessions.
Lowest altitude reached during all of the sessions.
Total cumulative ascent during all of the sessions.
Total cumulative descent during all of the sessions.
• Note that the historical record does not keep track of relative altitude
change.
• See “Clearing the Historical Record” for information about clearing the
historical record, which restarts all data values from zero.
How the historical record is updated
The watch performs the following operations when a save session is stopped
(after 40 records are stored or when you hold down C).
Data

Total Descent
Update Operation
The historical record value is compared with the current
session value, and the greater of the two is recorded in
the historical record.
The historical record value is compared with the current
session value, and the lesser of the two is recorded in the
historical record.
The current session value is added to the historical
record value.
To start a new save session
1. Press C to enter the Altimeter Mode.
2. Hold down C for about one second until REC
flashes on the display, which indicates that a
new session is in progress.
• During a save session, you can press E to
toggle between the current altitude screen
and the relative altitude change screen.

Press E.
3. The save session will continue until Periodic Record 40 is stored, or until
you hold down C for about one second until REC disappears from the
screen.
• You can recall saved records using the Data Recall Mode.
Other Altimeter Mode Features
This section explains other features and settings that are available in the
Altimeter Mode. Note that all of the information in this section applies to all
types of Altimeter Mode measurements, unless specifically indicated
otherwise.
Specifying a Reference Altitude
After you specify a reference altitude, the watch adjusts its air-pressure-to-
altitude conversion calculation accordingly. The altitude measurements
produced by this watch are subject to error caused by changes in air
pressure. Because of this, we recommend that you update the reference
altitude whenever one is available during your climb.
To set a reference altitude
1. In the Altimeter Mode, hold down E until
SET appears in the upper display area.
2. Release E, and wait for four or five more
seconds until either
OFF or the current
reference altitude value (if set) starts to flash.
This is the setting screen.
3. Press C (+) or A (–) to change the current
reference altitude value by 5 meters (or 20 feet).
• You can set the reference altitude within the
range of –10,000 to 10,000 meters (–32,800
to 32,800 feet).
• Pressing A and C at the same time returns to
OFF (no reference
altitude), so the watch performs air pressure to altitude conversions
based on preset data only.
4. Press E to exit the setting screen.

Altitude graph
The altitude graph shows Altimeter Mode
measurement results.
• The vertical axis of the graph represents
altitude, and each dot stands for 10 meters (40
feet).
• The horizontal axis represents time, and the flashing dot in the rightmost
column indicates the latest measurement result. For the first three minutes,
each dot represents five seconds. After that, each dot represents two
minutes.
• An out of range measurement result or a measurement error will cause the
column of dots for that measurement to be blank (skipped).
Altitude Differential Pointer
While a measurement operation is being performed in the Altimeter Mode, the
altitude differential pointer indicates the difference between the current
altitude and the last measured altitude.
Time
Altitude
Points to 9 o’clock for
differentials outside the
range of ±15 meters/49 feet.

Altitude differential examples
in the illustration are indicated
in 10-meter/33-foot steps.

Altitude differential pointer
• Altitude differential is indicated in the range of ±15 meters, in 1-meter units.
• Altitude is calculated and displayed using meters as the standard. Altitude
can also be read in feet units as shown in the illustration.
To turn display of the altitude differential pointer on and off
1. In the Altimeter Mode, hold down E until
SET appears in the upper display area.
2. Release E, and wait for four or five more
seconds until either
OFF or the current
reference altitude value (if set) starts to flash.
This is the setting screen.
3. Press D twice to display the pointer on/off
setting screen.
4. Press C to toggle display of the altitude
differential pointer on (
ON displayed) and off
(
OFF displayed).
5. When the setting is the way you want, press
E to exit the setting screen.
