Removing movement from Omega constellation vintage watch.

[east3rn]

Hello dear watchmakers.

I am about to work on a vintage Omega constellation automatic watch.

However I am having trouble getting the movement out of the case.

Movement + dial is stuck and won't come out from the back so I tried opening up the glass and that didn't work out very well.

Would it be necessary to open up the glass or is there a correct way ?

Thank you.

Remove the Bezel complete with glass and it should come out from the front use a loupe and find the edge of the bezel there is usually a slightly larger gap somewhere along the outer edge usually opposite side to the winding crown so you can  use a blade to remove it.
