demagnitser question

Recommended Posts


I'm looking to buy one.

Do those cheap blue ones on Ebay work or is my money better spent on the old style coil that you put the watch into ?

Thanks for any advice, Tom

Yes they do work, a few folk on the forum have used them with success including myself.  When using one, hold the watch on or very close to it then press the button on the unit.  While holding the button down, slowly pull the watch away to a distance if 450-600mm before releasing the button.  Do not keep the button held down for longer than ten seconds at a time or the unit will overheat.  

You may have to repeat this a few times to get rid of the magnetism, but it's the same with any demagnetiser.  Don't assume that the movement will be demagnetised after one go.  Another thing to remember, it is possible to inadvertently magnetise a movement with a demagnetiser.  If this happens, just go through the process again until you get the correct result.

These little blighters are fine. I've said many times on here demagnetize the movement should be the first thing before you undertake the repair it will save you time.

    • Folks: I'm looking to regulate my wife's new Bulova 98P170. I beleive it is using the Miyota 82S0 movement: I've been monitoring the watch's rates with the WatchTracker app for a while now.  During active daily wear it is +30.2 spd. Over night Crown down it is +15.4 spd.  So over 4 days it is running +24.8.  I'm hoping to get it down near +10 spd---with slight regulation. My trouble is, I'm not fully confident I can tell how this specific movement should be adjusted. See photo of the balance spring with the "+" and "-" indicators. To me it isn't perfectly clear how to slow it down. Sure, the retard indicator on the right would make me think I possibly to move the adjuster so the open gap (red circle I put in the pic) toward the "-". To do this, I assume I gently push against the adjuster on the right side (red arrow); however, it just isn't as clear as I would like.  Can someone please confirm?  I'm trying to tell if this would increase the balance spring lenght, but without better magnification, not sure. I am ordering a magnification eyepiece soon. Any thoughts would be greatly appreciated.  Please understand I'm fully aware I need to exercise extreme caution; make only ever slight movements as well as use a timing machine to see the instant impact of my slight changes.
    • Funny you should ask the question.  I was looking at some off the shelf cases for this purpose just this morning!  We'll have to give it a go and publish our results- there's a lot of orphaned Landeron movements that could use a new home.
    • You have to first identify the calibre number of the movement in this case im pretty sure its a Lecoultre cal.201 then search for a balance staff for that movement, all the usual places like part suppliers or ebay. Obsolete clock and watch has them at 25.00 a piece these movement went into aircraft clocks so parts will be scarce and costly  I recently needed a staff for a military pocket watch calibre 467 £20.00 each I then needed one for a calibre 415 a much rarer movement £8.95 for 12. So first off you need to establish the calibre.
    • Hi all, I have this little jaeger clock movement it measures 19 ligne about the size of a Pocket Watch but the pivot on the staff is broken, it measures 4 mm in length but where on earth do you start looking for a replacement.
