Professional Watch Demagnetizer Tool for Mechanical Watches - 110V Electrical Degausser for Screwdrivers & Tweezers - Portable Watch Repair Kit & Timekeeping Correction Tool Gifts for Men Women

I bought this Watch Repair Demagnetizer Tool as a second hope for fixing my recently purchased, magnetized automatic mechanical watch, which is typically running extra fast as a result. I had checked all my other watches and this one was the only watch that was magnetized. I believe it arrived in the mail like that. . The first demagnetizer/degausser I bought, the white one with the hole through it, didn’t work out of the box. It lit up the red light but that was all it did. It also looked heavily used. This blue one is the only other degausser available at Amazon at a reasonable price, and it's less than half the price of the white one. It comes from the same factory in China no matter which supplier you choose, just like the white ones do. So, I went with the first one that came up in my search with 2-day shipping. On arrival, it looked to be in a New condition. Good start! . If, and once, you manage to uncoil the power lead (!), there are actually zero included instructions on how to use it. YT is your best tutor here but I’ll explain. There is an alternating magnetic field created by the windings inside the box. Put the degausser on your ear and you should hear a faint hum when the button is pressed. If not, it’s a dead one! When you place a magnetized item near the pad on the upper surface of the degausser, the item will vibrate as the device’s alternating magnetic field pulls and pushes on the metal. This alternating field makes the magnetized item switch its magnetism many times a second. If you could shut off the device at the exact point the magnetic field switches from North to South, you’d demagnetize the item. However, you can’t be so precise. There’s another approach, fortunately. The strength of the hemispherical magnetic field reduces with distance until it’s effectively zero. So, if you move the item away from the blue box, the cyclic magnetizing effect also fades until it’s essentially zero. If you pull the item away quickly, the applied magnetic field doesn’t have time to fully decay in the item and whatever the last significant polarity of magnetic field influencing the item was, the item will retain that. Residual magnetism is not what you wanted! However, if you slowly pull the item away from the degausser, the magnetic field it creates weakens slowly around the magnetized item, and the item will essentially be given a weaker and weaker magnetism until, out of the influence of the degausser, it has essentially negligible magnetism. . So, to demagnetize your watch, hold the watch by the strap/bracelet so the watch face or back is just off, and above, the blue plastic, above the rectangular, marked ‘pad’. With your other hand, press the button and the red light will illuminate. Hold the watch in that position for about 10 seconds, and then very slowly start to lift the watch and move it SLOWLY away from the blue box until it’s at arm’s length directly above it. Let go of the button. Do this a couple times and your watch will be demagnetized. . I used my phone to check for the presence of magnetism using an Android app called ‘Magnetometer’. I did first try using a small compass. However, even placing a large, unmagnetized metal object near a compass can deflect the compass needle, confusing the observation. I opted for the more sensitive phone’s sensor. It’s more obvious that something is magnetized with the app. Move the back of your phone over a known magnetized item until the app readings go crazy, turn red and the phone vibrates, then you know where the sensor is located in the phone. Use that point to move closely around your watch. On my Pixel 6a, that was at the lower left back corner, if I remember correctly. I had a ‘red’ high reading around 180 before degaussing, at the 6 o’clock position of my watch face, and after, around 50. 40 to 55 was the average ambient reading in my home. . I did actually first check the degausser and its effectiveness on a small screwdriver, which I had magnetized. I preferred to initially test that rather than my expensive watch! The app was up in the 1500 range prior to using the blue box. Definitely magnetized!! After several attempts, I managed to get the reading down to about 94, consistent after the first try. So, I knew the blue box had worked. I couldn’t get down to the ambient 50 but the screwdriver no longer picked up a small screw. I was happy and proceeded to degauss my watch, with the desired result. . I am very happy that I’ve been able to fix my watch. I’m hoping the next time I use the degausser, it still works. I will update this review accordingly. However, as of now, I’m happy that the fix worked and only cost me about $10. 😊 . I can recommend you try this one and forget the more expensive white one!

Works as advertised. Saw a lot of people complain about the knot in the cord. Well, I was a Boy Scout so it wasn't even an issue. Edit: A previous commenter said to slowly move the item away while holding the button. This works. Also twisting and turning the item while holding the button works too.

It does work. My watch was running ~ 15 mins fast per day, and now it is less than a minute. It stopped operating, so I opened it up (two screws) and the problem was apparent ... one wire was disconnected. In operation, the unit vibrates, so that probably broke a poor solder joint. A quick resolder and up and running again. I also like the knot in the AC cord for strain relief.

I bought this to demagnetize a mechanical watch and it worked great for that but you can also use it to demagnetize other small things which you no longer want to be magnetized. As a test before I used it on my watch I successfully demagnetized a small screwdriver. The product came with no manual of any kind but it's pretty obvious what to do. Hold down the red button and a red light will come on to indicate it's running. Hold the object you want to demagnetize closely over it (like maybe a quarter inch or so). You will feel the object vibrating/buzzing a bit in your hand. Just do it for a few seconds at a time, it shouldn't take more than 5-10 seconds to work. The brand of the product isn't mentioned but mine says on the box it is a "Tui Chi Qi No. 888.600". It also came with a barcode you can scan with the Transparency app to verify the product's authenticity but I couldn't be bothered to do so. I will just take their word for it that this is the genuine Tui Chi Qi No. 888.600 and not some cheap counterfeit. In case you were wondering how it works it's something like this: when an object is magnetized the magnetic fields of all the particles inside are aligned. Think of it like a tug of war: if everyone is pulling in the same direction, you can pull pretty hard. The demagnetizer creates a powerful, rapidly changing magnetic field that mixes up the direction of all the magnetic fields inside the object. Now it's like a tug of war where everyone is disorganized and everyone's trying to pull the rope in a different direction from each other: it all cancels out and the net "pull" is pretty much zero even though everyone is still pulling just as hard as they were before.

Unit actually magnetized the watch further, and stopped working after the first use.

Worked great!

I used this to demagnatize a watch that was running slow by 20 min a day. I did this using videos as a reference. I placed the watch on the device and pressed the button. To my surprise the watch hands started spinning wildly. The second hand came of whatever it was mounted to! The watch is useless now. However the watch was useless before my attempt. This was a last-ditch effort as I did not want to take it to watch repair store and be charged half of what the watch was worth. I demagnetized several screwdrivers just see if it worked properly and it did. So I did not feel that it was right to send it back, when it was doing when it was supposed to do. However I cannot rate it highly and I would be very careful using it for watch repair.

This thing fixed my super fast Seiko watch. I did some research and a lot of forums said my watch prob needed to be demagnetized. I figured before I return it or take it to a watch repair and pay to have them fix it, I could try this cheap option first. Figured if it didn’t work I could return this unit and go on to plan b. I was skeptical of this product because it was so inexpensive, but I leaned on the positive reviews and I was pleasantly surprised. My watch now ticks on-time and I will be keeping this product.

It definitely works 👍. Friendly reminder to watch a YouTube video how to use it properly 🤝.

Just received the product today, tried it right always with numerous watches immediately. Conclusion: worked/not worked I couldn’t really tell, I did my best trying it out in different ways. I am still not sure how to use it properly and effectively. I guess I will keep it in case I have a really bad case of magnetism in the future.
