A tale of two questionable demagnetizers brief tool review For general edification, the insides of my demagnetizers, if you’ll forgive the stained vintage linoleum in the work room: Share this post Link to post Share on other sites.
However I skipped past it, thought it looked a bit ropey. The major difference being that the blue one has a small EI-core inductor and the big one has a large U-core inductor. June 14th, 5.

You need to be a member in wach to leave a comment. A tale of two questionable demagnetizers brief tool review I bought a similar blue one marked Etic from CousinsUK and i use it by pressing the red button while sweeping the object i want to demagnetize over the demag surface. Its probably exactly what Bergen sell, but at a fraction of the cost, it even has Bergeon branding.
ETIC Compact Watch Tool and Tweezer Demagnetizer – Swiss Made
I purchased this at a thrift store maybe 10 years ago as a “gee that looks sort of useful” purchase but never tried to use it, and i thought that i had lost it in demaagnetizer move, but found it in a box a couple weeks after the blue item arrived.
Once I have those sorted I want to replicate the rails that would have originally be on the sides an back to hopefully catch pinging parts then move on with the stain. Basic electrical laws dictate that the same electromagnet will have a stronger field with more voltage. Why precisely are magnetic fields potentially harmful to watches?
I suppose i may continue to use the blue one with bare movements, but will use the big boy for tools, cases, and movements that are still magnetic after a few tries on the little one. I,ll check back with your thread. Yes they do work, a few folk on the forum have used them with success including myself.
That made me brave enough to try the rest of the still running watch, so i did the same with it. June 14th, 7.

For parts julesborel provides some interchangability too. After several passes of the movement alone the compass mostly ignores it demagnetuzer it appears that the mainspring is still slightly magnetized.

The copper layer under it is for cooling.
Posted March 25, I wwatch have another barrel and a center wheel, so, I will be able to swap those. This one not only demagnetises small things like watches, but it also demagged my kitchen sharpening steel.
With the blue type, you cannot let the object to be de-magnetized etiv the surface, you have to hold it about 10 mm above the surface and then move it away. You can always look at a more expensive one later on. If you can afford the Etic, then go for it – I melted mine by leaving it plugged in and mistakingly setting a book on top of it which pressed the button down: You are right, the beat error increased a bit from around 0.

Never again sticky screws. Used in combination with the Lepsi Watch Scope — which syncs up with another Lepsi app to measure rate variation, amplitude, and beat error in just seconds — the demagnetizer is a useful and practical aid for do-it-yourself maintenance on the watches in your collection.
France adopted the metric system in but due to resistance in some areas, made demagnteizer compulsory inwell before your counter was made. Posted March 26, Couple of questions concerning Longines However I skipped past it, thought it looked a bit ropey. Snapped right into position and buzzed madly. Posted May 20, edited. For those outside the USA the country code is 1.
It’s possible that my Shanghai is a frankenwatch, demagnehizer a frankenmovement. To see Video on using a Demagnetizer and a Magnetizer. Far less than it had before, but still some. Don’t assume that the movement will be demagnetised after one go.

I have one of the drawer fronts that is trashed and another that has fallen apart and will need a few pieces replaced. A tale of two questionable demagnetizers brief tool review A fast running watch may mean demaggnetizer the hairspring is magnetized although the case may not be. Share this post Link to post Share on other sites. 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?
I don’t recall checking it’s accuracy when i got it, so i don’t know if it came to me magnetized and running fast or not. Originally Posted by smpcollector.
