Module No. 3452

Altitude Measurement

The watch takes altitude readings and displays results based on air pressure measurements taken by a built-in pressure sensor.

Important!

The altitude readings displayed by the watch are relative values that are calculated based on barometric pressure measured by the watch’s pressure sensor. This means that barometric pressure changes due to weather can cause altitude readings taken at the same location to be different. Also note that the value displayed by the watch may be different from the actual elevation and/or sea level elevation indicated for the area where you are located. When using the watch’s altimeter while mountain climbing, it is recommended that you regularly calibrate its readings in accordance with local altitude (elevation) indications.

When using navigation while receiving GPS signals, measured altimeter values are automatically adjusted in accordance with GPS signal data. Note, however, that this may result in some difference between the measured value and the actual altitude. Also note that the measured altitude value adjustment operation using GPS signal data may take a few minutes. The adjustment operation may take even longer, depending on your current environment. Regular manual adjustment of the measured altitude value using locally available information is recommended. The watch will not use GPS signal data to adjust measured altitude values for one hour after you adjustment the measured altitude value manually.

The altitude correction value and barometric pressure changes may result in display of a negative value.

Check the information below to find out about how to minimize differences between readings produced by the watch, and values provided by local altitude (elevation) indications.
