Stima Nivada 17 diver


Recommended Posts

  • 2 weeks later...

Hi, I reopen this topic because I have an issue, the tige of this movement is ruined and the original crown is missing.

My question is, in theory the tige of the "fhf 974" is the same of the "fhf 97"?

And the other question is, how can I choose the correct pitch of the screw in the crown? If I buy a stock of vintage crown I can find a correct one?

the tige of this movement is ruined

You are using the French name but most people won't recognize it. That is called stem, or sometime winding stem, or crown stem.

I think you mean the size (or diameter), not the pitch, which is always the same for a given stem size.

That is called thread in English. Screw is a fastener that fits into a fixed plate or body.

    • Yep, i pulled that up as well when i was looking,  there is definitely parts out there if you are prepared to go out and find them.  I watched that video years ago, I'm not so sure about probing the coil like that. If you are going to touch the coil use the side of the probe or at least shape a nice round end to it.

    • Hi. In the picture not only does it depict that the wheel is bent but also the plate or is that due to th angle of the picture.  Already received very good advise so I will butt out.
