You might not realize magnetism can quietly affect your watch’s accuracy, even if it looks fine.
If you suspect you’ve got a magnetized timepiece, you’ll want a simple method you can trust—without resorting to fancy gear.
I’ll walk you through a straightforward, five-step approach that lets you test the compass as you go and finish with a watch that’s back to normal, with one last check to confirm you’re done.
Key Takeaways
- Confirm the watch isn’t running and has an empty power reserve before starting demagnetization.
- Choose a demagnetizer (flat-surface or coil) and place the watch above/through it as instructed.
- Activate the demagnetizer and slowly lift the watch straight up to eye level while keeping contact with the device.
- After each pass, test for magnetization with a compass or magnetic sensor; repeat as needed.
- Verify the watch shows no magnetism and monitor accuracy to prevent future magnetization.
What Magnetism Does to a Watch
Magnetism can really mess with a watch’s timing. When magnetic fields interact with your mechanical watch movement, tiny internal mechanisms—gears, wheels, and the hairspring—can shift or stick.
Magnetism can disrupt a watch’s timing by causing gears and hairspring to stick or shift.
This exposure to magnetism can cause the hairspring coils to cling together, effectively shortening the spring and making the watch run faster. The result is erratic timekeeping or even stoppage, so a watch can become a magnetized watch if its daily gain or loss exceeds one minute.
ISO 764 sets a baseline, requiring resistance to magnetic fields up to 4800 A/m (about 60 gauss), but many modern watches tolerate far higher fields, sometimes around 15,000 gauss. Everyday sources—microwaves, computers, smartphones—can magnetize a timepiece if placed nearby.
Understanding how magnetism disturbs the internal mechanisms helps you gauge watch accuracy and recognize when magnetic exposure is impacting performance, guiding you toward appropriate demagnetization steps.
Signs Your Watch Is Magnetized
If your watch starts gaining or losing time by more than a minute a day, that’s a strong clue it’s magnetized. You’ll notice indicators of abnormal accuracy in mechanical watches when magnetic force sticks the hairspring coils, making it run erratically or even stop. A magnetized watch often exhibits consistent deviation, not just occasional fluctuations, so you can trust that trend as a sign you need to investigate.
To test magnetism, use a compass; if the needle moves markedly near the watch, you’re detecting magnetism influencing the movement. While mobile apps like LEPSI can help, physical compass tests tend to be more reliable for practical detecting. Keep in mind that magnetism affects accuracy and can disrupt daily wear.
Signs Your Watch Is Magnetized point you toward demagnetize steps, since removing magnetic influence restores proper function. If you confirm magnetization, prioritizing demagnetize actions will help regain intended performance and reliability.
Tools You’Ll Need for Demagnetizing
To demagnetize a watch, you’ll need the right tools. A watch demagnetizer is the primary tool, typically priced between $15 and $50, and it comes in two common styles: flat surface and coil.
For a flat surface demagnetizer, place the watch face up, press the button, and lift slowly away from the device. If you prefer a coil demagnetizer, pass the watch through a circular opening with slow, smooth motion to guarantee the magnetic field is canceled.
Before you begin, verify the watch isn’t running to avoid potential damage during the process. After demagnetizing, use a compass app or a traditional compass to confirm the device is no longer magnetic. This quick check helps the watch owner verify the result.
Keep electronic devices away while you work, as residual fields can affect other gear. With the right tools, you can safely restore accuracy without guesswork.
Step-By-Step Demagnetization Method
Before you start, make sure the watch isn’t running and has an empty power reserve to avoid potential damage; then you’ll demagnetize more safely. In this step-by-step method, you’ll use a demagnetizer. Place the watch above the demagnetizer pad and press the activation button to begin.
Slowly lift the watch straight up while still holding the button, until it reaches eye level, then release to complete one cycle. This process is simple, but accuracy matters with each repetition. After each demagnetization cycle, test the watch with a compass or a magnetic sensor to confirm effectiveness.
If the watch is magnetized, repeat the process until the compass shows no interaction. Maintain a steady, calm motion to avoid introducing new magnetism. Once you’re satisfied, inspect the watch runs normally and the magnetic sensor reads neutral when tested.
This method minimizes risk and helps preserve performance without unnecessary steps.
How to Verify and Prevent Future Magnetization
One quick check is to test for magnetization with a compass—if the needle noticeably moves toward the watch, it’s magnetized. To verify ongoing health, monitor your watch for accuracy; a gain or loss of more than one minute per day may signal magnetization.
Keep your device away from electronic devices like smartphones and speakers to minimize exposure to magnetic fields. When you travel, avoid airport scanners and other strong magnetic fields to reduce risk.
Consider using a watch demagnetizer periodically as part of routine maintenance to prevent future issues. Store watches separately from magnetic sources and inspect for changes in regulation of timekeeping rather than relying on guesswork.
If magnetization is detected, recheck with a compass after demagnetizing and compare results over a few days to confirm consistency. Maintaining proactive checks helps with long-term accuracy, reduces downtime, and supports effective preventive care against unexpected magnetization.
Frequently Asked Questions
How to Easily Demagnetize a Watch?
You can easily demagnetize a watch by using a handheld demagnetizer.
With the watch off, hover it over the device and press the button, then slowly lift it away while the unit’s field is active.
Test it with a compass; if the needle still moves, repeat once more.
Regular checks help, and store watches away from electronics to minimize future magnetization.
If doubts linger, consult a professional for precision demagnetization.
What Are Three Ways You Can Demagnetize a Magnet?
Three quick ways you can demagnetize a magnet: use a demagnetizer to apply an alternating field, which neutralizes magnetism; heat it near or above the Curie point to disrupt domain alignment; or strike it with a hammer, which rattles the internal particles and reduces magnetization. You could also move the magnet away from a strong field slowly, letting domains randomize as the field lessens. Be mindful of potential damage with hammering.
How to Demagnetize a Watch Without a Demagnetizer?
You can try demagnetizing a watch without a demagnetizer by using nearby magnets or magnetic sources. Briefly expose the watch to a strong magnet, then flip it and bring it close again in multiple passes to disrupt the magnetic alignment.
Check with a digital compass after; if the needle steadies, you’re likely fine. If it still drifts, wait idle and retest later.
For accuracy, consider a professional demagnetizer if issues persist.
How to Fix a Magnetized Watch?
To fix a magnetized watch, demagnetize it using a proper demagnetizing tool, or take it to a professional if you don’t have one.
Ascertain the watch isn’t running, then follow the device’s instructions: position it above the magnet, press the button, and slowly lift away.
Recheck accuracy with a compass or phone app, and repeat if needed.
Keep it away from strong magnets and monitor timekeeping regularly.
