    Watch Magnetised is it permanently damaged

    I recently took my speedy pro out of storage and placed it next to my compass and the compass needle moved meaning the watch is magnetised. I don't know how long it has been magnetised.

    Do the home demagnetisers for sale on Amazon/ebay work? Or am I best off taking it to a jeweller?

    Can most jewellers repair it?

    If it is repaired, will there be any lingering, permanent damage?

    Take it to a good watch shop. Call first to make sure they have a degausser.
    I bought an eBay degausser and used it once on a watch with good results.
    There won't be any permanent after effects so no worries.
    BTW, if it is magnetized, it should be running very fast. If not, I wouldn't even worry about it.

    Definitely not an expert but yes they do work they’ll be some tips on YouTube or just take it to the shop but it’ll be a bit dearer . Finally no it’s fixable the only thing wrong will be the timekeeping,once it’s demagnetised it’ll be fine

    Re: Watch Magnetised is it permanently damaged

    I used to take my Reverso to the JLC boutique on a monthly basis to demagnetise. Then I bought a small demagnetizer online and solved my issues. Cellphones really cause a lot of problems to my handwinders.

    APRO 15400 seems to have some resistance, but my Speedy cal 863 is certainly affected

    If you are into collecting watches, you should have a demagnetizer--and yes, they work--mine cost $15 on the bay several years ago, and have used it on about one out of every 5 watches I have bought (more than 200 and counting...). No lasting damage, easy to do--if you are in a hurry, take it to the local shop, and it will be OK in five minutes.

    Is the accuracy off noticeably?

    The tiniest bit of research would have answered this question. No damage at all.

    A watch will run faster if it is magnetized. As pointed out, if the watch is running accurately, don't worry about it.

    If a watch is slightly magnetized, the watch as a whole can be demagnetized. If a watch is heavily magnetized, then it must be completely disassembled and all ferrous components must be individually magnetized. I had a severely magnetized Zenith El Primero, it was fine after servicing and demagnetization.

    No it’s totally fixable. I did read that some of the cheapo demagnetisers you can buy struggle with a whole watch sometimes. Don’t know how true it is though.

    Yeah, it's done for, I am afraid. I will graciously offer you £50 for it.

    Re: Watch Magnetised is it permanently damaged

    :) Funny thread.
    OP - watch can be magnetized with no damage - simply demagnetize it. Also - it may move compass hand a tiny bit even if not magnetized. If accuracy is fine - leave it alone.
    As far as demagnetizing - some jewelry shops can do it free or for nominal fee. Or you can get a demagnetizer off eBay for <$15 and they work just fine.
