removing back from helvetia

[gary17]

hey guys

Been trying to get into the movement on this now for a few days. Yes i am using the corerect tools. but with no luck it is solid no movement at all. I have just taken it out of a shallow bowl of oil.(just covering the back) that it has been in for 4 days and still not a thing. No movement.  Tried razor blades around the join and absolutely nothing.

Any suggestions gratefully received.

Dont wanna start using heat.

cheers

Glue a nut on with super glue. Glue can be dissolved later with acetone.

Hi Gary  the nut trick is a cert for tight screw backs.

The shape of the case makes it difficult to hold it firmly without damage. There you have to find a solution first!

I would put a temporary strap on it and then put the watch in a good solid watch vice like this. Not expesive. Just be careful to look out for the spring bars breaking out of the lugs or the bar holes becoming damaged if it is so tight. Or a hard timber insert to fit tight  between the lugs. If the lugs weren't  so thick and part of the cushion case i wouldnt have tried this.
