No idea why: melted gasket, corrosion, mixture of both, etc. That's why I used the torch: I put it in a vise in a case-holder, played the brush flame on it to heat the case-back and make its dimensions change vs. the mid-case. I know it's impossible for you to believe that the LG or the Bargeon could fail, but in my case, I assure you they did. The watch was a Tudor D-D Jumbo, still in my possession.

Small consolation but here's what it looks like, AS 1895, ref 7020.
