Current Stopwatch Session Record
The current stopwatch session record contains the data described below. The contents of this record are retained until you start a new Altimeter Mode stopwatch measurement session.
Data | Description |
High Altitude | Highest altitude reached during the current Altimeter Mode |
(MAX) | stopwatch session. |
Low Altitude | Lowest altitude reached during the current Altimeter Mode |
(MIN) | stopwatch session. |
Total Ascent | Total cumulative ascent during the current Altimeter Mode |
(ASC) | stopwatch session. |
Total Descent | Total cumulative descent during the current Altimeter |
(DSC) | Mode stopwatch session. |
•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 Altimeter Mode stopwatch session record data is updated Note
•When you press E to start a new Altimeter Mode stopwatch session, the watch will clear data that is already stored in the current stopwatch session record.
•The watch takes altitude readings and calculates data as described below, and updates the current stopwatch session record accordingly. Note that measurement and saves depend on whether or not the watch is in the Altimeter Mode.

Historical Record
The historical record keeps track of high altitude, low altitude, total ascent, and total descent values across multiple Altimeter Mode stopwatch sessions. The contents of this record are updated continually while an Altimeter Mode stopwatch operation is in progress.
How the historical record is updated
The watch performs the following operations continually while an Altimeter Mode stopwatch operation is in progress.
Data | Update Operation |
High Altitude | The historical record value is compared with the current |
| reading and the greater of the two is recorded in the |
| historical record. |
Low Altitude | The historical record value is compared with the current |
| reading, and the lesser of the two is recorded in the |
| historical record. |
|
|
Total Ascent | The current Altimeter Mode stopwatch session value is |
Total Descent | added to the historical record value. |

|
•See “Clearing the Historical Record” for information about clearing the historical record, which restarts all data values from zero.
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

•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).
Recalling Altitude Data
Use the Data Recall Mode to view altitude records currently in memory, as well as the current Altimeter Mode stopwatch session record, and the historical record. Altitude records are created and stored by the watch in the Altimeter Mode.
Data Screens
The following explains the contents of each of the screens that appear in the Data Recall Mode.

Altitude Records
These are records of the 20 newest altitude readings taken with the watch by you. If you take more than 20 readings, the watch will delete the oldest readings to make room for the newest readings.
Current Stopwatch Session Record
The following data items are included in the current stopwatch session record.
