My watch says I get a bit more than 2 hours of REM a night which the Internet says is plenty! The biggest changes to my sleep are not eating late and hitting fiber goals.

    They are better than having no data. It does measure a ton of info related to heart and temperature which are decent indicators.

    Your watch can't measure your brain or eyes, only secondary effects (and not as precisely as actual medical equipment). It's a rough estimation at best.
