The watch uses a built-in sensor to automatically measure air pressure and altitude. The barometric altimeter measures the altitude by comparing the air pressure with the atmospheric pressure at sea level.

Air pressure is measured in hectopascals (hPa). Altitude is measured in metres (m) above sea level

To see the air pressure, open the watch Barometer application on the smart watch. Swipe up/down the screen to view air pressure (AP) and altitude changes. Air pressure is measured in hPa.

*NOTE* Air pressure changes over time and from place to place
