Does anyone know either where I can find a movement holding spring or how to improvise one myself? My case ring had only part of one left! And then does it need to be attached or can the spring just be sandwiched between the case ring and case back? I'm assuming that's how it functions. Please correct me if I'm wrong.


Thanks,
Curt

I had the exact same problem with a 6139-6002 I recenlty had overhauled. The spring was totally gone. My watchmaker put the watch back together, and there don't seem to be any problems caused by the lack of the spring.

The movement spring helps hold the movement and dial steady in the case and kind-of, sort-of should be there.

Since this part is long discontinued and impossible to find without cannibalizing, a reasonable "Plan B" is to use an "O"-ring to take its place. A very, very slight bit of silicone lube will prevent the case back from bunching the "O"-ring when closing the case.

Thanks guys.


I had part of the spring in my watch and it seemed to be kinda working. Had a close look and didn't like the rusting spring half so picked it off the case ring. With mine, the movement is clanging back and forth and the counter weight rotor hits the case back now. I thought about an o-ring but finding the correct dimension may be tough. I'll take my calipers to the o-ring bin and maybe get lucky. I do have a dozen case back gaskets coming from Asia so maybe cutting a few to use as spacers will work. They seem a bit thin to get enough space filled though. I don't have pusher springs or o-rings either, so when I install those there may be enough resistance from the pushers to keep the case ring from moving back and forth?? I'll report back.

My overhaul included new pusher gaskets. Maybe that is helping keep the movement ring in place and the movement centered in the case. I don't have any evidence of the rotor hitting the caseback.

Case back gasket worked as spacer in place of movement holder spring. It had to be cut to fit, but everything is now nice and tight.

I have two 6139's - one has that ring, one doesn't - I don't notice any difference.

The o-ring trick, instead of the spring, works the best from my own experience.

I have seen other solutions like a round bended paperclip but also a lot glue or sealants.... :-\

Interesting - yes, at least one other member has mentioned that the movement holder spring doesn't seem to make much difference. The only thing I can suggest is that I don't yet have pusher springs installed, they seem to add a bit of tension against the movement holder. It's possible that your watch without the movement holder spring has good pusher springs kinda sorta holding the movement holder in place? My panda seems to be like that.
