Help Needed With Fitting A New Crystal

[Alaskamick]

Jaquet Cobur, Swiss made, 17 jewels, Incabloc, Automatic.

 

From the 60's or 70's I think.

 

I recently got this watch very cheap but in need of a new crystal and a COA although it does run for a short while.

 

I've removed and replaced loads of crystals on Omega, Fossils etc. in the past so I thought it would be a doddle to do this one.

 

Tried to remove it with my normal multi finger compression tool but not matter how tight I get the tool it will not budge the crystal.

 

When I have the tool tight I've tried turning it and pulling it but no luck. It's almost as if it's glued solidly to the case but no sign of adhesive 

 

Any advice on how to remove it would be much appreciated.

 

The photos aren't good but I got them off the internet.

 

Thanks a lot, Mike

As far as I can see it looks to be an armoured crystal with a tension ring. If you remove the movement then you should be able to push it out with your thumbs. You will then need to press the new one in

Thanks a lot Andy, you were spot on.
