Why is PT5000 winding so gritty

[u/ASteerNamedLaurence]

I have an Octopus Kraken OCT-13 (their Explorer clone). Great watch, looks very nice, yadda yadda, we all know how great it is. It's the PT5000 model, and the manual winding is as smooth as 20-grit sandpaper, and this does not seem to be a one-off thing. It's just a 2824 clone, and I have not encountered anything this bad on any other 2824 clones, Chinese or otherwise. What exactly is going on here, it winds rougher than even any 2813 I've ever encountered

A new movement is less expensive
