Always-on Altimeter
Perhaps most significantly, the Apple Watch SE is actually getting one brand new feature this year that debuted with the Apple Watch Series 6: the always-on altimeter.
It’s a smaller thing — unless you’re a hiker, that is — but it does mean that even the Apple Watch SE will be able to keep track of your elevation as you wander through the great outdoors, and you’ll be able to see it at a glance.
