    A squash ball ususally works fine if you have one :)

    Damn, there's some seriously crazy answers being pulled out for what's a genuine question from a concerned horological enthusiast.

    Why is this a "crazy" answer? It's not easy to open this and best left to the professionals to handle...

    I use a normal 3-jaw case opener as @Radiumpassion suggested. Mine is an L-G, but it's the same principle. I don't find these any more difficult to open than case-backs with 6 notches.

    Cheers I didn’t think that would work on that style of caseback, I’ll try the ball option first then the 3-jaw if it doesn’t work

    All kidding aside. Just be sure the 3 jaw has a good grip or scarring will occur.

    One slip with a tool and the watch is scratched !
    I would make sure that the person opening it knows what they are doing!

    How to remove this type of caseback? - Carefully. ;)

    My votes on the squash ball.

    Joking aside, if the squash ball won't do it first time then I always go with the "thermal shock" method: invert a can of compressed air and spray the back of the watch; the propellant instantly freezes the caseback, causing it to contract and breaks (usually breaks) any liquified seals. Wipe off any moisture and try the squash ball again.

    Mind your fingers!

    I hope people here didn't think I was trying to be a smart ass with my previous suggestion; I wasn't.

    It's by far the best method for opening watches that hasn't been opened for years bar semi-pro setups. Virtually no chance of leaving marks, pretty much fool-proof, I do it all the time...

    So I should glue the socket right to the case back? Is there something you are forgetting to include in this nutty idea? ;)
