Anyone recognize this movement?

[rogart63]

Have a few movement that looks like this. All of them are missing the clutch wheel. As they are pretty clean it would be great if i could do something with them? But need to find out what it is and if i can source some clutch wheels . Thre is no inscription anywhere on them. Only says 17 jewels. I have a suspicion that it could be some kind of chinese movement? But?

Well, original old ones have some reputation among collectors. Recent mass produced pieces are crap. No oil hole on the jewels, non-working autowinder, wobbling datewheel.... Although, they can be really accurate if You keep the same daily routine
