What should you do about the magnetization of mechanical watches?

My Watch Is Running Fast!

Through your time collecting watches, you may encounter a mechanical watch that you notice has a significant change in its timing. A watch that would typically run fast seconds per day will suddenly increase to hours per day. This is an indication that your watch may have somehow become magnetized. The article below discusses magnetized watches, its causes and how it can be addressed.

So, What Happened?

In daily life, strong magnetic fields can be seen everywhere. Mobile phones, telephone handsets, computers, radios, magnetic buckles on bags, refrigerator doors, induction cookers, and various other appliances may cause watches to be magnetized.

The most typical one is the magnetic clasp on the bag, which has a great influence on the mechanical watch, so the mechanical watch will be magnetized again unknowingly, and the magnetism will not recede by itself in this case, so it needs to be demagnetized and repaired to return to normal.

Once the watch is magnetized, it will affect the accuracy of the watch and bring a big error, making the watch go fast and slow.

The most serious thing is to make the balance spring ring stick to the ring, if that is the case, the watch will be faster than 2 hours almost every day. In addition, like the automatic bearing part, the magnetic field will attract more iron chips and debris, making the ball bearing more worn and affecting the automatic winding efficiency.

How can you tell when a watch is magnetized?

compass

You can use a more sensitive compass, put the compass flat on the table, and then hold the watch close to the compass, do a round-trip fast rubbing action, if the compass hand swings, it means that the watch is magnetic.

Lepsi App

Using the Lepsi App:

If you do not already have it, it can be purchased on iTunes for free (Apple only).

Setup the App to position the magnetic sensor on your phone (follow instructions).

Click start and wait 3 seconds Put your watch approximately 1 cm away from the sensor, without touching the screen.

A message will display “Magnetism Detected”, if you watch is magnetized, if not your watch is fine.

How Do I demagnetize My Watch?

  • Bring your watch to your watchmaker. Every watchmaker has demagnetizing equipment available in their shop and will be able to take care of your watch in a few minutes. The cost of this service is generally nominal or even free, depending on your relationship with the watchmaker.
  • Buy your own equipment. Generally, you can buy your own demagnetizer online for less than $20 and just wait for it to arrive. The process of reversal is as simple as pressing a button for 10 seconds and then slowly lifting your watch off the device.

Finally, there is no need to worry about magnetization when using roroos watch winder, because all our products have been anti magnetized.
