The human REM sleep cycle is 90 minutes long. As long as your sleep in multiples of 90 minutes, you’ll feel rested.
9 hrs or 6 hours would work but not 10 hours or 30 minutes.
Edit: I meant the entire non-REM and REM sleep stages altogether and not just the specific section of REM.
I don’t know about your German (har har), but I’m not very confident in what my Garmin or any fitness watch detects on sleep. I got a Garmin to replace my FitBit, wore them both for a while, and saw they didn’t have much consensus on sleep data.
Yeah I more took issue with OP saying REM sleep, after a quick search it seems sleep might be in blocks of 90 minutes with REM coming at the end of the each block, and less that REM sleep is that long.

My
GermanGarmin tracks my sleep daily and I’ve never had a REM stage of sleep be 90 minutes.I don’t have a German that would track my sleep :(
They’re all the rage, if you can get a mute one then it’s better otherwise they keep banging on about fair wages and sleep breaks 😩

Thanks for the insight.

I don’t think this tracking can be that accurate.
Well after a cursory look online it seems OP was talking incorrectly.
Studies show that sleep itself is segmented in 90 minute blocks with REM coming at the end. Rather than the REM section being 90 minutes.
Also OP is claiming you’ll feel rested, which is completely different than actually being rested.
