    Caseback press- how to handle the bezel

    This is for my 40mm aerospace that has a rotatable bezel. I’m just trying to get my brain in gear before the press arrives and I use it for real.

    With the watch face down on the nylon die, and the cupped die beyond the crystal, that would have it resting on the bezel. Is this safe, or is it best to remove the bezel first?

    Cheers

    Dave

    Ideally, use a large enough and deep enough die to clear the bezel and support the lugs, I' m not familiar with the watch so I can' t be more specific.

    as Paul said, also make sure you you the correct size for the caseback, too small and you risk causing an indent in the caseback.

    I also have a stubborn case back to put back - from your description - 'clear the bezel and support the lugs'. Do you mean I would choose a die that is big enough to clear the the bezel edge the die 'shoulders' would then rest onto the lugs when you press down on the 'press'?

    I think this is what’s described-

    I'm amazed that an Aerospace doesn't have a screw on caseback (I've never actually noticed when I've looked at them).

    I have a Certina Moonphase chrono that I can never refit the caseback to. First time I swapped the battery, I had to take it to a friendly jewellers to get it refitted and then, I forgot all the hassle the previous time and had to do it all again a couple of years later!

    Now I have a big red note in my watches spreadsheet to remind me NOT to try swapping it myself again!

    I hope you have more luck!

    Mine is older so press fit, all the newer models have retention screws

    Amazon is delivering the press and my batteries today, so I’m hoping to know if it all works by later on

    This has come up a few times over the years, with speculation that it's something to do with the potential for titanium surfaces to bond together.

    Just keep an eye on the Caseback gasket- not sure what type these have
    Some of the Citizens I’ve done have a nylon crush gasket that can be reused but need to stay oriented the same way as they are shamfered
