Altitude graph
• In the Altimeter Mode, press the A button to toggle between the altitude
graph and the altitude change indicator. The altitude change indicator
shows the relative change between the latest altitude reading and the one
before it.
• Nothing is displayed for the altitude change indicator when the current
altitude reading is outside the watch's altitude measurement range (–700 to
10,000 meters).
