Hermle and Kundo electrochron - anniversary clocks

[Gabriel025]

Hi! 

I just bought another two beautiful anniversary watches - Hermle and Kundo watch. Kundo is interesting... I tought that it will be quartz, but it's not... Well, the problem is that lower part is bended. The central shaft scrapes against the cup and the clock stops after a few rotations. I tried to straighten it, but failed. Can someone explain to me how to disassemble that lower part to get to the shaft? There are no screws. How can I remove the torsion spring? It's the same thing with Hermle... I know how to dissasembly torsion spring, but not the rest. The both clocks are from the same seller...

Thank's

Dell is the person for this he restores these 400 / anniversary clocks. I have myself but  this type I have never seen.

Great, thank you. It's very rare model from Kundo. Clock does not have main spring but electric motor... Interesting clock... But the lower part (part that hangs on the torsion spring) is the same as on the fully mechanical model. I think that the torsion spring is the same like on my other mechanical model. I simply don't understand how someone managed to bend that lower part. All the parts are made of brass and seem to me to be press pressed into each other. I don't have the courage to use force.

Sorry don’t have anything to do with quartz or electronic clocks but one looks to be mechanical, at the top of the torsion spring there should be either a screw or a pin holding the top block to the saddle once removed it will free the top block thus allowing the spring to be removed so I would imagine that the electrical one is the same , some torsion springs are all one piece IE the top and bottom blocks are press fitted to the spring others are screwed.
