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.

Thanks for the insight.
