I just noticed my smart watch has altimeter and barometer, but I have never checked how precise they are...
I bought it for sleep monitoring initially, but have kept it on my wrist almost 24/24 for more than 2 1/2 years now, showers, kayaking, etc.
It's a GTR2e, they also have a rugged model, T-rex which is more popular for sport and outdoor activities...
