Is there Altitude measurement on Apple Watch ? Which models .

[Humbardi14]

I read somewhere that the Apple Watch can measure altitude but I do not know what models do it.
I appreciate your information. Thanks

I think Series 3, 4, 5 have a barometric altimeter, and series 6 and later and SE have an "always-on" barometric altimeter.

Both will provide altitude when requested or for an app, but the latter can display it continuously in a complication.

Use the Compass app on Apple Watch

The Compass app shows the direction your Apple Watch is facing, your current location, and elevation.

The altitude is determined by a combination of GPS (and possibly other positioning information) and barometric pressure changes. The GPS sets the baseline, and the barometer detects the variation more accurately than GPS can.

Note that it is often not very accurate, especially if GPS reception is poor (like inside a building). Altitude is the least accurate positioning provided by GPS, and its accuracy is very variable. Lower your expectations.
