    demagnetizers

    hi guys,

    does anyone know how powerful a demagnetizer has to be to demagnetize a watch?

    just looking at a machine that does screws and screwdrivers, but are they strong enough for a watch?

    Re: demagnetizers

    I actually have a question regarding demagnetizing/degaussing.

    When you have a degausser is it as simple as passing the entire watch case and all over/through it? and approximately how many passes does it usually take?

    I have NO idea for power questions...but it seems I need one now too...

    As for finding a demagnetizer I would look here:

    or here:


    I read somewhere you can find some for a little as $26...hopefully someone will post where...

    The little blue demagnetizer should be powerful enough to demagnetize a watch.

    One pass is normally enough.

    so case and all I am presuming [?]

    I actually work in media and have access to a degausser [probably used for video/audio media]...would you foresee any issues with that? Thx!

    I have a seagull ST25 running a few minutes fast per day...and I am guessing it got magentized recently

    Re: demagnetizers

    I've used a demagnetized for video tapes and I moved the watch all around that for perhaps 15 seconds or so - worked well. I've also used one of those very strong little magnets and it too worked.

    If the watch is only running a couple of minutes fast a day it's probably not magnetized. However, if it's running hours fast/day it probably is. Either that or the spring got hung up on itself - something that's often quite obvious. I've used magnets to fix those problems as well.
