    Any tips on removing these screws?

    Just received this brand new Festina watch and knew that the battery would need replacing. It has sat in a drawer for a few years and never had a battery replacement. I managed to get one screw out but the other three I can't get to budge. I'm frightened to use too much force because I don't want to damage the screw slot or snap the head off the screw. I'm not a big fan of this caseback arrangement, but there's probably not much choice with the case shape. Any tips to loosen the screws?

    It's possible (even likely) that the screws have a drop of 'threadlock' on them that has gone hard ?....Wear it for a few hours, or keep it somewhere warm (like an airing cupboard); but not hot... you don't want to cook the seals ! Then, try again.

    Thanks for the tip. I'm wondering if a little drop of WD40 in each hole might help?

    Take it to a jeweler....If they damage it, their fault.....If you damage it, well your fault...

    What do you think will happen if the jeweller breaks a screw, he'll replace the watch?

    Rule #1:

    When lubricant says "universal" on the can, it means it's universally useless for anything you can think of.

    WD40 is the pinnacle of uselessness though, as it's able to damage quite a number of polymers and elastomers in particular.

    The bulletproof solution:
    Drill the heads off, and use new screws when assembling.
    A bit of grease on the thread, will avoid this issue in the future.
    The reason to drill the heads off, is to avoid ending up snapping the screw in a place that does not allow you to remove it with pliers once the back is off.


    If there is Loctite involved, take a soldering iron to the head of the screw, and remove it while it's hot.

    You're clearly not an engineer ;)


    Is it possible you're not using the right sized screwdriver? I've been you are several times and for the most part trying a different screwdriver that fits just a hair better gets the job done.
