The Impact of Magnetism on Your Timepiece
Mechanical watches rely on tiny metal parts working in perfect harmony. The balance spring, a delicate coil inside the movement, controls the timing by oscillating back and forth. When exposed to magnetic fields, this spring can stick to itself or other components, causing it to oscillate faster than normal. This results in the watch running fast, sometimes by several seconds or even minutes per day.
Magnetism does not damage the watch permanently, but it disrupts the delicate balance needed for accurate timekeeping. The effect can be sudden and noticeable, especially if your watch was previously running perfectly.
Common Sources of Magnetism in Daily Life
Many people do not realize how common magnetic fields are in everyday environments. Some typical sources that can magnetize your watch include:
Smartphones and tablets: Devices like iPads have magnets in their cases or speakers.
Laptop computers: Internal components and speakers emit magnetic fields.
Speakers and headphones: Powerful magnets inside audio equipment can affect watches nearby.
Handbags and purses: Magnetic clasps or closures can expose your watch to magnetism.
Magnetic clasps on jewelry or accessories: Even small magnets can cause issues if close to the watch.
Being aware of these sources helps you avoid accidental magnetization.
Symptoms That Indicate Your Watch Is Magnetized
If your Rolex or other mechanical watch suddenly gains time, look for these signs:
Gains 15 seconds or more per day without any other changes.
Stops or runs irregularly after being near electronic devices.
The second hand may jump or move unevenly.
The watch feels magnetized if a compass needle moves when placed near it.
If you notice these symptoms, magnetism is likely the cause.

How to Fix a Magnetized Watch
The good news is that fixing a magnetized watch is straightforward and usually inexpensive. Here are your options:
Use a demagnetizer: Watchmakers and jewelers use a device called a demagnetizer to remove magnetic fields from the watch. This process takes only a few minutes and restores normal function.
Professional service: If you are unsure or do not have access to a demagnetizer, take your watch to an authorized service center or experienced watchmaker.
Avoid magnetism in the future: Keep your watch away from strong magnets and electronic devices that emit magnetic fields.
Preventing Magnetism from Affecting Your Watch
Prevention is the best way to keep your Rolex running accurately. Here are some practical tips:
Store your watch away from electronic devices when not in use.
Avoid placing your watch on or near speakers, laptops, or magnetic clasps.
Use a watch box or case that offers some protection from magnetic fields.
Be mindful of magnetic closures on handbags or jewelry.
By following these simple steps, you can reduce the risk of magnetism interfering with your watch.
When to Seek Professional Help
If your watch continues to run fast after demagnetization, or if it shows other issues like stopping or losing time, it may need a full service. Mechanical watches require regular maintenance every few years to clean, lubricate, and adjust the movement. A professional service will also check for any damage caused by magnetism or other factors.
Final Thoughts on Watch Magnetism and Accuracy
Magnetism is a common but often overlooked cause of sudden time gains in luxury watches like Rolex. Recognizing the symptoms and understanding the sources can save you worry and unnecessary repairs. Using a demagnetizer or visiting a watchmaker usually solves the problem quickly. Protecting your watch from magnetic fields helps maintain its precision and longevity.
