I just purchased a 1980 Seiko that was running +96 MINUTES a day(+4 minutes an hour!!!). Seller offered to pay for shipping to return it, but instead I bought a $20 demagnetizer, followed the above instructions, and now it's running as it should. I get to keep the watch I love and the seller doesn't have the headache of dealing with a watch that most would deem unwearable. Thank you!!
Sounds like your 1980 Seiko was trying to catch up to 2024 (as I write this). Wearing that watch, you spend your whole day saying, "Whaaat, is it that time already?!"
The little transformer housed in the plastic case is used to magnetize or demagnetize a watch. The idea is, you want to create chaos in the molecular field of the magnetized watch, or scramble the molecular structure. If you simply leave the watch on the top and press the button for 10 seconds without moving the watch, you will align the molecules up and create a magnetized watch, if you push the button while holding the watch about a half inch above and slowly move the watch around to crown up to crown down to crown side to side, it will scramble the field and demagnetize the watch. I am guessing slowly moving the watch up will eventually do the same thing. Also, since it's the balance spring your demagnetizing its best to stop the movement (Hack it) Good informative video for anyone with an automatic/mechanical watch, as these little 20 dollar magnetizer/demagnetizers are a must-have.
thanks so much, Omega wanted to charge me £360 to check my fast running Omega Seamaster - I followed your utube vid and fixed it for £16. Thanks again and good luck to you
Great video, however here are some corrections: - You should move the watch away from the demagnetizer slowly to get the best demagnetization. You can also do it with the watch in several different directions to get all the spots in the watch. However it is only the demagnetization of the hair-spring that is important., and it might be difficult to do this with the back still on the watch, especially if the watch has a magnetic shielded back. - The phone does no contain a magnet, it contains a magnetometer (used to measure compass direction). Hence any app that can show the compass direction or even better, the strength of the magnetic field, can help you. The app mentioned in the video seems to only show yes or no which is not so helpful as the actual measured value.
@@Chrono24Official For Android I like the app "GPS Status". It is mainly used to show detailed GPS info, but in the menu you can go to the option: "Diagnose sensors". There it shows you a list of all sensors on the phone, including the magnetometer in X,Y, and Z direction. I recommend to use the raw-uncalibrated value from the sensor. It also has a "calibrated" value, but this is deceiving as this tries to eliminate all external fields in order to calculate compass direction, hence not recommended for actual measurements of external fields.
Using a magnetic field sensor to diagnose a magnetized watch (as you said what these apps actually do) is something that I can understand. But I really struggle to accept what some people on internet say about using a compass for diagnosing a magnetized watch. The compass hand is nothing but a magnet. So, even if you take a piece of not magnetized iron close to it, its hand will still move. So, I don't think that test can be correct. Do you agree with me, or you think that I am missing something here?
@@a000ab A compass will show movement if a metal object is placed near it. A compass that shows a slight, tiny movement when a watch is moved close to it, indicates that a watch is not magnetised. A compass that shows a lot of movement when a watch is moved close to it, indicates that the watch is possibly magnetised. A compass should only be used as an indicator to help diagnose if a watch is magnetised or not, it should not be used as 100% definitive proof. I use a compass and I also use the Lepsi app, which is easy to calibrate, easy to use, and best of all it is free. Something to keep in mind is that watch bracelet clasps, spring bars, watch buckles, etc, can also be a source of magnetism and cause a watch to become magnetised. I only recently became aware of this from watching a video called “How To Avoid Magnetisation In Your Watch Collection” by “Peter Kotsa” it is about magnetised watches, bracelets, spring bars etc,and how to check for and demagnetise them. Edit: The cheap watch repair kits that are sold on Amazon, eBay and AliExpress can also be sources of magnetism. I recently checked my watch repair kit and found the majority of the tools including the screwdrivers and watch case back opener were magnetised. I know it is obvious to most people, but for anyone that doesn’t know, never leave your watches or tools anywhere near your sound bar, speakers, subwoofers and obviously anything else that has magnets in them.
Thank you, Sir. That method easily demagnetized my Hamilton! I’m not sure if it mattered, but I pulled the crown out to stop the movement prior to placing on the demagnetizer.
I had previously not known about pushing the button for 10 sec(thanks!). My Tudor BB36 was running 35 seconds a day slow. I had to do this procedure twice but I got it down to four seconds per day slow.....a remarkable improvement.Did not do a third time as did not want to push my luck.Bottom line.......this worked for me !
Quite often, it's the strap pins and buckles that are magnetized, not just the watch. I had a watch that was not magnetized but the watch pins and buckles were.
You can always use a compass to detect magnetised watches, either a real one or one that you can install on your smartphone. A 1° change in the presence of your watch is normal, but if introducing the watch causes the compass to swing more it needs demagnetisation.
Thank you so much for this! I almost sent a watch in for service for being 3 minutes a day fast. I downloaded the app and replicated how you used the demagnetizer. My watch is now + - 0 seconds in the last 6 hours.
Stop the watch first? I was told: '' this process should only be performed on watches that are not actively running. If your watch has a movement with hacking, pull the crown out to stop the movement first. If you don't have hacking, set the watch aside, and allow the power reserve to empty before using the demagnetizer. ''
I have a Tudor that was running very fast so I found one of these demagnetizers on Amazon. It took several times to get my watch to slow down. Several times with me keep the watch on the pad for a minute or two and there is still a trace of magnetism. I don’t know if my watch was just heavily magnetized or my demag device is weak. But it did work eventually kinda.
Thank you for making the instructional video. It is very well done. Video is clear and pleasing. The music is subdued with a pleasing cadence and tone. The base is not overpowering. It’s simple, to the point and memorable. I’ll check out some of your other videos. Oh and that is a beautiful vintage Omega. You portrayed it in such a way that I now want to find and purchase one.
Thanks! I just bought the same demagnetiser on Amazon, before watching your video. I noticed my watch was gaining more and more time, so I held it over a compass and the needle went crazy. Fingers crossed I can solve it with this cheap device 👍
Thanks for this tip! The Lepsi app was a bit hit or miss for me...it showed both a magnetized and a non-magnetized pocket watch as magnetized but only the magnetized watch made the compass needle hop all over the place.
Good, I bought same Blue demag' unit from Amazon and found it worked on my Sekonda manual watch, but I had to; start with watch rear case resting flat on blue surface, for four seconds then slowly lift it a foot or so up away slowly (all time holding red button down> repeat about four times over an afternoon until watch was running normally again but now functioning properly
Merci beaucoup. J'avais l'appareil mais sans savoir comment l'utiliser. Au lieu du téléphone j'ai pris une boussole. Ma seiko automatique prenait 4 minutes d'avance en 24h... la boussole tournait dans tous les sens... j'ai utilisé l'appareil demagnetiseur comme vous le faites et la boussole ne bouge plus du tout. Chez Seiko il voulait changer le mécanisme pour 200€. L'appareil 14€ sur Amazon et la montre tourne super bien. Merci
This demagnetizer works by putting changing magnetic fields through everything. You have to hold it close, then slowly pull it away, so the magnetic fields in the watch steel don't disappear, but slowly taper to a net zero. Not polarized and not big.
Thanks for the video. I have a Breitling Superocean Heritage ii that I felt it may of got magnetized while moving as I carried a pair of speakers. The watch was running well and then gaining time and then it just stopped. I downloaded the Lepsi app and confirmed that watch was magnetized. I checked it a 2nd time and noticed the second hand moving again. Now it's been an hour and still running spot on. I just ordered the blue demagnetizer anyway but weird how the watch just started working. Could that 2nd pass over the iPhone have corrected the problem as it did not read magnetized the 2nd time. Well my watch is working again. Thanks
Thanks for the video! However, I would like to know if there's any harm in demagnetizing a watch frequently if one were to be constantly exposed to magnetic forces. Let me know please!
There's magnetism all around you especially from electronic devices. If you have a sound system or any type of speaker there is a very very strong magnetic field around those devices, far more than there would be from that demagnetiser. I've never heard of a magnetic field being harmful in any way. The earth has a magnetic field which is how compasses work. You're probably getting confused with radiation from x-rays extra which would be harmful over time but as far as I know a magnetic field only effects metallic objects not an actual person. Hope that helps explain it.
Hi I bought that demagnetiser about a year ago and never used it. One of my mechanical watches then started to lose time so I placed it on the demagnetiser and the time keeping went off the scale. I tried it first with the watch face down and it started losing minutes a day. I then tried it face up and the watch started gaining minutes a day!!! I think I was leaving it on the demagnetiser too long and then suddenly removing it. Either way it messed up the watch big time. I then saw your video and tried it face up for 10 seconds only and removed it slowly upwards. The watch has now returned to good time keeping but I don't understand why the demagnetiser ruined the time keeping previously. Does this thing do harm to a watch if you leave it on the demagnetiser for too long, and what's the correct way the watch should be, face up or face down when demagnetising? That Lepsi app is iPhone only but I found similar apps in the Google Play Store.
Hi Mike, thank you for your questions. Well, I don't have all the answer to you but this is what I know. The watch should be placed on the demagnetiser face up. You then push the button. While you are pushing the button with one hand after counting to 10 firmly lift the watch upwards and when about 30-40cm above the device let the button go. I only ever used the Lepsi App on iPhone so not sure if there is a Google Play version, but I think there might be apps for Android as well by other companies. Hope this helps!
Hello Mike, the demagnetizer relies on an alternating current electromagnet, this means it is switching the magnetic field from one way to another very quickly. If you leave the watch in place on it it just ends up being magnetised one way or another. To efectively scramble the aligned magnetic fields of the watch and thus demagnetise it, you have to slowly pull away so that the switching magnetic fields slowly taper off and "scramble" the magnetism. If the magnetism is scrambled, all the tiny bits fighting each other cancel out, resulting in no net magnetism.
One of my vintage Seikos was running like 15 minutes fast and hour I work with magnets quite a lot and had no idea it could have an effect on my watch 😂
Do not rely on a compass or phone app to indicate that your watch is magnetized. I've had two watches suddenly run unusually fast and neither moved the needle on a compass. But, both returned to their normal accuracy after several passes over the demagnetizer. Sudden inaccuracy is more of an indicator than an app or compass.
It's a very terrifying procedure until it actually works. I got a watch with ETA movement and it's running +20s a day. When I first try the demagnetizer it magnetize it even more, the watch is running +150s! Until I do it the right way, the watch now run +2s, I'm happy with the result.
I got this. I have a rolex daytona that runs 10 seconds every minute too fast. I checked and it was magnetised. I used this and checked and not magnetised. But still runs 10 seconds every minute too fast. Should the accuracy come back immediately or over time?
I have a seiko alpinist that runs slow, it is supposed to be magnetic resistant, could it be magnetized? Is it safe to use the demagnetizer even if it is magnetic resistant?
I tried this app. I’ve done its configuration putting my AirPods Pro inside the case (it has magnets inside to keep the headphones inside to make them don’t fall off opening the case upside down for error). The app has counted 1400 circa of magnetism when I’ve put my AirPods Pro with case near my iPhone 11. The position of the sensor was the same as yours. When I’ve putted my mechanical watches near my iPhone the app always said “NO MAGNETISM”. After all my watches tests I’ve put again my AirPods Pro with case near and said “MAGNETISM DETECTED”. So my mechanical watches are not magnetised, right? Can I rest calm and assured that all of my watches didn’t make “MAGNETISM DETECTED”, so they’re not magnetised? When I’ve put my AirPods Pro near has said “MAGNETISM DETECTED”. Thanks dude💪🏻💪🏻
Video interessante. Ho sempre creduto/letto che non bisogna mai avvicinare un orologio ad uno smartphone poiché questo può magnetizzarsi per tale motivo tengo i miei orologi a debita distanza, oggi scopro che basta non poggiarlo sul telefono e comunque è sufficiente una distanza di 1 cm. Ottimo 👍
Can you demagnetize the watch while it's running? I have a Tourbillon Era Prometheus and noticed that the balance wheel stopped moving while it's being demagnetized. Is this normal?
I bought one device just like that and it didn't demagnetize my watch. I checked it with a compass. In fact, the demagnetizer makes the compass needle move to the other side from where it was moving before...
I keep reading that before Demagnetizing a watch, it;s important to wait until the movement is totally unwind / stopped? Is that true? And if yes, could it be done by just using the watch hacking feature?
I noticed that and I downloaded Magnetic Detector LITE instead. It works great and just put the watch near where the circle in the video is, the new app even lets you know the number of the level of magnetization!
I did this with the cheapest one. It was running fast 25 seconds a day, now is running slow 8 seconds a day. Should I introduce a magnet again slightly to try and balance it out?!
For some reason my Seiko Automatic does stop on my wrist everytime But when I wind it up and leave on my bedside no trouble and keeps excellent time.Maybee someone can assist me in this regard Thanks for a great video.
Download the Magnetic Field Sensor App and if anything is magnetised it sounds an alarm. If I go within 2 feet of a loudspeaker it goes crazy. Here's the link: play.google.com/store/apps/details?id=com.tuber.magneticsensor.magneticfield
+1 there, not everyone sups at the Apple table. I have an amazing "Hong Kong Police" compass quartz watch until that day when us Android lot get the app (maybe android fones don't have the magnety thingy inside?)
I don't know what to think about this. All my watches are magnitized but only one is off track. The rest are very precise. I tried to demagnetize the faulty one but nothing happens. It is still off track like -10 minutes in one hour
My local watchmaker is a stubborn old goat, wouldn't even do it for me, don't know where else to go so I'm learning to do things by myself, for myself.
Going fast is usually magnetism, going slow is need of service. You could regulate it so it advances a bit but that would last you a long while but it will slow again needing further regulation. You can get away with this until you get to the end of the little +- gauge on the balance cock, any further advancement will likely damage your watch needing a more expensive repair. If you get to the end of the gauge it really is service time as your watch is indicating it is tired, it is dirty, it is dry and beginning to gum up from dried oil particles, small worn metal particles and of course the ol' favourite... mangunge, yes our skin, sweat and other doings get into even the best sealed watches.

Do you need to pull the crown out before using the demagnetiser??
Thank you for such an informative video
But wont the phone magnetize the watch again if you put it near the phone?
Thank you
You're welcome
Do not rely on a compass or phone app to indicate that your watch is magnetized. I've had two watches suddenly run unusually fast and neither moved the needle on a compass. But, both returned to their normal accuracy after several passes over the demagnetizer. Sudden inaccuracy is more of an indicator than an app or compass.
Terrific! Thank you!
A pleasure! :)
Where is the link to the application? I did subscribe 🤔
Hi there! Should you demagnetize watches while they're running or no? Does that harm the balance wheel?
Same question here because I have read somewhere that you need to have the watch not running or the mainspring totally unwound before you demagnetize.
i did it while its running and i didnt notice any harm but i guess to be safe you can wait until its no longer running or pull the dial out
Can you run the demagnetizer while the watch is still wound and running?
You can!
but you shouldn't
If you don’t have or can’t get Lepsi just use a compass
It's a very terrifying procedure until it actually works. I got a watch with ETA movement and it's running +20s a day. When I first try the demagnetizer it magnetize it even more, the watch is running +150s! Until I do it the right way, the watch now run +2s, I'm happy with the result.
Now I know my Vostok K-35 (ref no. 350503) is magnetized AF! Runs at about +45/+60 seconds per day.
I got this. I have a rolex daytona that runs 10 seconds every minute too fast. I checked and it was magnetised. I used this and checked and not magnetised. But still runs 10 seconds every minute too fast. Should the accuracy come back immediately or over time?
what happened to LEPSI app, what are other alternatives?
Nice info, thanks :)
Hi, can a quartz watch demagnetizied too, or just the automatics?
5 months late, but a demagnetizer will demagnetize pretty much(*) anything.
Don't you have to let the watch run down completely first? I noticed that the watch was still running when you demagnetised it?
I have a seiko alpinist that runs slow, it is supposed to be magnetic resistant, could it be magnetized? Is it safe to use the demagnetizer even if it is magnetic resistant?
I tried this app. I’ve done its configuration putting my AirPods Pro inside the case (it has magnets inside to keep the headphones inside to make them don’t fall off opening the case upside down for error). The app has counted 1400 circa of magnetism when I’ve put my AirPods Pro with case near my iPhone 11. The position of the sensor was the same as yours. When I’ve putted my mechanical watches near my iPhone the app always said “NO MAGNETISM”. After all my watches tests I’ve put again my AirPods Pro with case near and said “MAGNETISM DETECTED”. So my mechanical watches are not magnetised, right? Can I rest calm and assured that all of my watches didn’t make “MAGNETISM DETECTED”, so they’re not magnetised? When I’ve put my AirPods Pro near has said “MAGNETISM DETECTED”. Thanks dude💪🏻💪🏻
thanks 👍
Worked perfectly! 🙂👍
Glad to hear that! Now it is running smooth again?
Its ok to do the magnetizer while watch is running?
Thanks.
You're welcome
Can i use that device to degmanatize a flip phone cover , i got problems with my s pen due the magnet from behind.
Video interessante. Ho sempre creduto/letto che non bisogna mai avvicinare un orologio ad uno smartphone poiché questo può magnetizzarsi per tale motivo tengo i miei orologi a debita distanza, oggi scopro che basta non poggiarlo sul telefono e comunque è sufficiente una distanza di 1 cm. Ottimo 👍
Thank you!
Can you demagnetize the watch while it's running? I have a Tourbillon Era Prometheus and noticed that the balance wheel stopped moving while it's being demagnetized. Is this normal?
Did you ever get an answer to your question?
Can t find the app using the link
What’s that little puck your watch is sitting on?
does the movement have to be stopped and drained?
I do it exactly like that 👍🏻
Wont the handphone magnetised the watch when both are too close to each other?
I bought one device just like that and it didn't demagnetize my watch. I checked it with a compass. In fact, the demagnetizer makes the compass needle move to the other side from where it was moving before...
Is it ok to put the watch face down on the demagnetiser. My watch is on a bracelet I can’t remove.
Who makes the demagnetizer and where can I get it?
The Lepsi app is no longer available, any suggestions?
You could just use a compass too to check if your watch is magnetic.
I tried to look for the app. And I could not find it in the Apple App
I keep reading that before Demagnetizing a watch, it;s important to wait until the movement is totally unwind / stopped? Is that true? And if yes, could it be done by just using the watch hacking feature?
this information would be helpful, yes
You have the let the movement wind down completely not just pull the crown out (hack)
@@HarshilPandit Unfortunately, if you are demagnetising an automatic watch, even a slight movement of the case can start it up again!
Good
My watch is on time but the movement of seconds hand is weird, it skips 3 second the leap to 4 second. Haven’t check if battery running low.
Can I demagnetize a watch by moving it over a magnet and then drawing it away from the magnet slowly?
Can Rolex datejust get magnetised even though they have blue hairspring?
How i can download that to android device?
Its seems that is there no app.
Lepsi is no longer on the APP store. Is there another app you suggest?
I noticed that and I downloaded Magnetic Detector LITE instead. It works great and just put the watch near where the circle in the video is, the new app even lets you know the number of the level of magnetization!
@@TheYoungMontanaThank you!
@@TheYoungMontanahow much did the Numbers on the app move? Mine startet at 50 and moved +1-5 ved the Watch was over. Dies that mean it is magnetized?
@@frederikkerdil8995 I’m no expert but if it’s only 1-5 then I do not believe it’s magnetized
I just demagnetized two of my watches Thanks
I did this with the cheapest one. It was running fast 25 seconds a day, now is running slow 8 seconds a day. Should I introduce a magnet again slightly to try and balance it out?!
Anyone?
I need to know why my automatic watch at 15:15 the toungs are touching and it stops! How can i solve my problem?
How to configure this app?
Can I use this to demagnetize my house keys?
For some reason my Seiko Automatic does stop on my wrist everytime But when I wind it up and leave on my bedside no trouble and keeps excellent time.Maybee someone can assist me in this regard Thanks for a great video.
App is only available for Apple. What app for android phone?
how often do i need to demagnetize my watch ?
thank you for your advice !
There is no rule for that. I would say you should do it when you notice that it is not running accurate :) Magnetization could be the reason for that.
Thank you! App for Android?
I am personally not aware of a similar app for Android, sorry.
Use a compass. It will react to your
watch if it's magnetised.
Download the Magnetic Field Sensor App and if anything is magnetised it sounds an alarm. If I go within 2 feet of a loudspeaker it goes crazy. Here's the link: play.google.com/store/apps/details?id=com.tuber.magneticsensor.magneticfield
+1 there, not everyone sups at the Apple table. I have an amazing "Hong Kong Police" compass quartz watch until that day when us Android lot get the app (maybe android fones don't have the magnety thingy inside?)
Physics Toolbox Magnetometer
Shouldn’t you pull the crown out and stop the watch before demagnetizing the watch?
I don't know what to think about this. All my watches are magnitized but only one is off track. The rest are very precise. I tried to demagnetize the faulty one but nothing happens. It is still off track like -10 minutes in one hour
💯
My local watchmaker is a stubborn old goat, wouldn't even do it for me, don't know where else to go so I'm learning to do things by myself, for myself.
My mechanical watch is losing time. Any ideas if demagnetizer could be useful ?
It could! Would be worth a test.
Going fast is usually magnetism, going slow is need of service. You could regulate it so it advances a bit but that would last you a long while but it will slow again needing further regulation. You can get away with this until you get to the end of the little +- gauge on the balance cock, any further advancement will likely damage your watch needing a more expensive repair. If you get to the end of the gauge it really is service time as your watch is indicating it is tired, it is dirty, it is dry and beginning to gum up from dried oil particles, small worn metal particles and of course the ol' favourite... mangunge, yes our skin, sweat and other doings get into even the best sealed watches.
Placing a mechanical watch with a ferrous spring steel spring anywhere near a phone will magnetise the spring. Better to use a compass.
