It's a little circlip style retaining clip to keep the pinion from riding up out of position. -

Doctor, If the train turns when hands setting, this means that the train is not blocked. And this is true for all kinds of trains design. The train is normally blocked by the lever. So, put the lever in place and try again. If the train turns again, search where You have placed some wheel upside down and it is not meshed with the next one in the chain. The other thing is the amount of friction that is needed to overcome when setting hands. Yes, the friction part here is in the great wheel, and it needs lubrication. If the parts are dry, then friction will arise, seizing will happen and thus risk of breaking of teeth in the train or breaking of joint wheel/pinion. I don't know this calibre, but I guess the clip is part of the friction device. But for sure it stays tilted, which is not normal. So, pay attention to it and see what is wrong there -
It most certainly should be there, but it should fit better than that. Here is what it should look like.

This way is dangerous. The problem is that the collet is not expected to be perfect in this tool and the wheel used for the grinding is big and easy can touch the balance wheel. Can You show the bottom side of the balance wheel?
