Afaik the movement is a modified Hangzhou 5000A: https://watch-movements.eu/blog/2021/08/01/mikrorotor-auf-chinesische-art-hangzhou-5000a/
It's a quite new movement used in gen and rep watches and I don't know how robust it is. I own three watches (2 Patek reps and the Sólás Starlight) equipped with it and they are working fine. However I wear them only casually.
Hangzhou movements are classified on the basis of the first digit. Thus, 5000A (start with 5) is a mid-class movement. The factory's high end movements are named 7xxx.
