We are surrounded by all kinds of electronic products, such as computers, smart phones, TVs, microwave ovens, etc. Although most of these electronic products are necessities of life, they are also a source of radiating magnetism. This level of magnetic force does not affect the human body, but it is not the case for watches. For a watch, even a small amount of magnetism can have a great effect.
What is “magnetized”?
The state in which the watch is adversely affected by magnetism is called “magnetized”. Watches can be magnetized as long as they are close to magnetic objects, especially mechanical watches that are extremely susceptible to magnetism.
Metal magnetization
Watches are made up of various parts, and most of these parts are made of metal. When metal receives magnetic force, it will attract each other like a magnet.
This situation is metal magnetization. After the parts of the watch are magnetized, the parts begin to attract each other. But this will cause the parts of the watch to shift or even stop working. Especially watches are mostly precision machinery, and a little magnetic force can cause huge effects.
The influence of magnetism on analog battery watches
After the analog battery watch is magnetized, the magnetic force will interfere with the operation of the motor in the watch. The motor installed in the battery watch is driven by magnetism, so the watch will turn quickly, delay or even stop after being magnetized.
Digital battery watch not affected by magnetism
Although analog battery watches are susceptible to magnetic interference, but digital battery watches are not. Even if the digital battery watch is close to magnetic objects, there will be no influence. This is because the parts in the digital battery watch will not be magnetized, so you don’t need to be as careful as other watches when you wear it.
Mechanical watches are affected by magnetism
The internal parts of a mechanical watch are mostly made of metal. Therefore, under the influence of magnetic force, the parts will become magnetized, which will interfere with the operation of the balance wheel of the mechanical watch, causing the watch to have problems with fast rotation or delay. I will introduce to you how to degauss.
Magnetic object
The following products emit magnetism, which affects the operation of the watch.
- • Audio equipment
- • Smart phones
- • Magnetic necklace or magnetic health items
- • Alternating current transformer for computers of other products
- • Induction cooker
In addition, there are many magnetic objects, and when the watch is close to these magnetic objects, the watch may be magnetized.
What happens when the watch is magnetized
The following will introduce what are the problems with magnetic watches. If your watch has these conditions, please contact the manufacturer or repair shop.
- • After the calibration, it will be inaccurate immediately
- • Even if the battery is replaced, the watch still stops moving (when the watch is an analog battery watch)
- • Even if the balance spring is rotated, the time of the watch is still delayed (when the watch is a mechanical watch)
The necessity of demagnetization
When the watch is magnetized, it needs to be demagnetized. Demagnetization refers to the process of removing magnetism from the watch.
When degaussing, you need to disassemble the watch, confirm the parts one by one, and perform demagnetization. No matter how small parts are magnetized, the degaussing of the watch can be said to be a very detailed technology. In addition, the magnetic force is not visible to the naked eye, so the magnetic inspection of the parts is particularly important.
General households only need to use commercially available degausser to perform degaussing operations. However, the degausser may also cause the watch to be magnetized. Once the sequence is wrong, the watch will be magnetically disturbed. Therefore, it is recommended that you directly seek the assistance of the manufacturer or repair shop.
Invisible magnetism
When the compass is close to the watch, the pointer will start to rotate sharply; it can be judged that the watch has been magnetized. However, human eyes cannot see magnetism, and daily life is full of interference from various electronic products. Therefore, it is usually difficult to tell whether a watch is magnetized without using a compass. Smart phones, audio equipment, and even magnetic health items around us may affect the watch, so it is very difficult to determine whether the watch is magnetized. Compared with other error conditions, this kind of error is really harder to detect.
Keep away from magnetic objects
When the watch is magnetized, it needs to be demagnetized. You should also be careful in daily life and try not to let the watch close to magnetic objects. Since the magnetic force will weaken depending on the distance, as long as you stay away from magnetic objects, you can avoid the watch from being affected by the magnetic force. As long as the antimagnetic watch (above JIS1 type) is more than 5 cm away from magnetic objects and the non-magnetic watch is more than 10 cm away from magnetic objects, it will hardly be interfered by magnetic force. But you still need to pay more attention to avoid putting the watch on electronic products such as smart phones that you usually carry.
