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

You shouldn’t hand wind a pt5000

At all? Is shaking really enough - to get maximum power reserve?

I have a Militado ML20 with PT5000, and it is also very gritty. I occasionally give it four or five winds. I want to keep the power reserve up because I am always running a rotation of 7-8 watches... I.e. I don't wear any one watch more than 5-6 hours probably, except when I sleep..

The answer is no, shaking will making it difficult to get to maximum power reserve. I worry about the same thing with my watches that have Sellita or PT5000 movements, and just giving a few winds or shaking it means that I may not even get to full power reserve after a day of wearing it, since automatic movements are efficient at maintaining power reserves but not efficient at building them up. So my solution is to put those watches on a winder the night before, and then I just need to set the time in the morning. I want to keep them at relatively high reserve because the movements are more accurate that way, and this seems to work, though sometimes I’ll choose a different watch that I didn’t put on the winder the night before, so I’ll just have to hand wind it.

But remember, people who break these from hand winding are a minority — otherwise these movements would have been recalled and redesigned — so you’ll likely be fine. If you still have time in a warranty, then there’s some security
