    Back removal

    A quick one.....

    Got a cheap quartz bike clock i can't get back off to change battery. Does it look like threaded or pop-free? Not any gap to get a blade in.
    If screw-off - hints?

    Cheers!

    As there are no indents for a tool, I doubt that it's screw off.

    If you run a nail round the edge is it possible that a thin blade could get in all round the back rather than having a specific indent to get in on one place?

    I've replaced the battery on my Oxford bike clock a couple of times but that's a simple 4 philips screws to get the back off then a miniscule screw that looks like a dust particle that keeps the battery in place

    Thanks for that - will see if I can grip it such that said blade doesn't require a trip to A&E

    I have one of those blunt-ish blades for watch backs, but it was too blunt I think.

    I suspect you'll need one sharp enough that when it inevitable goes through the palm of your hand, it will leave a nice clean cut.

    I had a quick look on youtube and there are loads of people removing similar backs with stanley knives and fine screwdrivers, slipping all over the place. Amazed I've not witnessed someone losing a finger.

    Chainmail butchers gloves might be the answer https://www.amazon.co.uk/Stainless-R.../dp/B01ABW7SOM

    Or a new clock (I've got a spare in the garage I could send you if it all goes horribly wrong)

    I suspect in general the manufacturing cost is less than the cost of getting the battery replaced by a jeweller, so ongoing maintenance isn't high on the list of design priorities

    Again, thanks!

    I'll have a stab (see what I did there) with a stanley, but will see how it looks/feels first.

    I have a local watch service/retailer - who only charged me 5 per watch battery installed, a year ago............. Worth throwing a fiver at.

    Thanks for the offer of your spare, but I have a fall-back digital one - just prefer the analogue.

    Now - where's that first aid kit?

    Seems like the one I have in the garage is identical.



    So identical it also has a flat battery.

    Back came off very easily with a Stanley knife though

    It is the same, indeed.

    Back now off, and internals as you show them. Takes a 377a battery, so ordered a couple up.

    Thanks again.
