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.
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.

Watch sleep trackers are absolute bullshit btw
They are better than having no data. It does measure a ton of info related to heart and temperature which are decent indicators.
No data is better than shitty data more often than not.
Again, the heart rate monitoring and temperature reads are very accurate.
Where’s your* source?

It can maybe detect sleep paralysis or other things that indicate this is REM
Well duh but it’s a damn close estimate.
