I have a titanium screwback and I can't for the life of me get the caseback off. I've tried a 2 prong and 3 prong tool with all my strength. I added some 3 in 1 oil, let it sit, tried again no luck. First time I haven't been able to remove a screwback here. Took it to a jeweler, no luck. Was told to invest in a new watch. Real helpful. Took it to another jeweler and the watchmaker will look at it Monday. They think some of the threads might be misaligned.
I really don't think one of those ball things would do anything in this case. I was wondering if heating it or freezing it would make any difference? I was thinking maybe a hammer of some sort to pop the threads in place if they are misaligned as well. Thanks for any suggestions.
