Will a mechanical watch be susceptible to magnetism after passing through airport security?

Magnetism and electricity are both physical phenomena in nature, and where there is electricity, there is magnetism. In today's social life, electronic products are everywhere, therefore, there is a strong or weak magnetic field around us. Various types of permanent magnets are also widely used in electrical appliances, typically speakers and motors, and both magnets and DC magnetic fields can magnetize "hard magnetic" materials such as steel.

There is also the magnetic buckle on the leather bag, and the watch and credit card are the most afraid of being stained with magnetism.

There are many steel materials in mechanical watches, such as large and small steel wheels, escape wheels, shaft tenons of gears, bearings, screws and hairsprings, so watches are very susceptible to magnetization. Once the mechanical watch is magnetized, the impact is first of all to increase the error, and in serious cases, it will also stop the watch. Although quartz watches do not have the problem of being magnetized, they may stop in strong magnetic fields.

The magnetic field is everywhere, and it is impossible to prevent it, and sure enough, it turned out to be a watch with a good end, and suddenly the error became larger, and the first thing to guess was whether it was magnetized.

The watch is generally magnetized and goes fast, (serious will stop) if the hairspring is sucked together, the hand will go faster, about 2 hours or so faster, steel parts are most likely to be magnetized, including the escape wheel and pallet fork, as well as the hairspring, magnetic force will affect and interfere with the balance wheel's ** cycle. So, now in daily life, strong magnetic fields can be seen everywhere, the most typical is the magnetic buckle of the leather bag, which thing is made of aluminum, iron and boron, the magnetism is very large, and there are various electrical appliances, so the watch is easy to be magnetized unconsciously

The easiest way to tell is to use a sensitive point compass and lay it flat. Then the watch is quickly repeated over the top of the compass at close range, and this action also needs to change the watch in a few more directions, and then repeat... As long as the needle of the compass moves.

It means that the table has been magnetized. It will definitely have an impact, it depends on the brand and quality of your watch!

If the hairspring of the watch is magnetized, the watch will not be accurate. The influence of the wearer's usage habits may cause an increase in the time error. But you don't need to worry, please send the watch to the designated repair point for professional inspection and adjustment, and the watch can be restored to the normal error range.

When a mechanical watch goes through airport security, it needs to be removed and placed in a baggage or basket for security checks.

Taking Shenzhen Bao'an International Airport as an example, the precautions for airport security check are as follows:

1. Please do not try to include any items prohibited by civil aviation in your checked baggage, carry-on baggage and carry-on items.

2. If you are traveling with "three super" (oversized, oversized or overweight) items, please consult the airline of your flight in advance.

3. When undergoing document inspection, please prepare the boarding pass and valid boarding documents (which must be the same as those used when booking tickets) in advance, and take the initiative to hand them over to the document inspection personnel for inspection.

4. Before accepting the security check of carry-on baggage, please take out the laptop, umbrella, power bank and liquid items in the baggage and pass through the X-ray machine separately.

5. Before undergoing personal security checks, please take out your metal objects (such as mobile phones, keys, watches, cigarettes, coins, etc.) and put them in your luggage or baskets for security checks.

When you take an airplane, your watch has to go through the security check, and when you pass the security check, the watch and mobile phone need to be put in the designated basket and checked one by one.

It is forbidden to carry the following items on board civil airlines in China:

1. Firearms, military or police equipment (including main parts) and their imitations;

2. ** items, such as ammunition, pyrotechnic products, blasting equipment, etc. and their imitations;

3. Controlled knives;

4. Flammable and explosive materials, such as matches, lighters (gas), alcohol, paint, gasoline, kerosene, benzene markers, rosin oil, cigarette cakes, etc.;

5. Corrosive materials, such as hydrochloric acid, sulfuric acid, nitric acid, liquid batteries, etc.;

Take off your watch during the security check. Remove metal items from your body and place them in your baggage or basket for security checks. If there is metal on the body when passing through the security gate, such as belt buckles, jewelry, etc., it will make the security equipment sound an alarm, and the security personnel will check whether there are dangerous items.

Please do not attempt to include any items prohibited by civil aviation in your checked baggage, carry-on baggage and carry-on baggage.

When undergoing document inspection, please prepare your boarding pass and valid boarding documents in advance and hand them over to the document control staff for inspection.

Take off your watch during the security check. When passing through the security check, watches, mobile phones, lighters, etc. are put in a small basket, and if there is metal on the body when passing through the security gate, such as belt buckles, jewelry, etc., it will make the security equipment sound an alarm, but the general staff can detect that there are no dangerous items. <

During the security check of the aircraft, it is necessary to take off the watch. When passing through the security check, watches, mobile phones, silver, lighters, etc. are put in a small basket, and if there is metal on the body when passing through the security gate, such as belt buckles, jewelry, etc., the security equipment will make an alarm sound, but the general staff can detect that there are no dangerous items.

Yes, as long as it's a normal watch. All objects can basically be seen clearly in the security inspection machine, so it must be no problem, you can carry it with you without checking it in. If you can't see clearly, the security inspector will ask you to take it out and go through the machine again.

Put it in the suitcase and go through the security scan without any problem. If you carry it with you, you need to remove it and go through the security check. Hope it helps.

No, the security door is based on weak magnetic field sensing technology. Electromagnetic radiation is safe for the human body, and mechanical watches cannot be magnetized.

The magnetic field strength of the security gate should be much lower than the anti-magnetic standard of the watch, so even if the watch passes through the security gate, there is no need to worry.

If the watch is in your luggage and passes through the security check of the X-ray machine, first of all, the mechanical watch will not be affected in any way. So for a quartz watch, there is an IC chip on its internal circuit, so theoretically, X-rays will have a little bit of "interference". It is said that the penetration of the X-ray machine can penetrate a 30mm thick steel plate, but fortunately, the time to pass through the security check is very short, and the strength is also very low, and even most of the low-exposure film can pass safely.

The electromagnetic radiation of the security gate is negligible, and it uses weak magnetic field sensing technology; The power is very small, many times smaller than when talking on a mobile phone, and the radiation is smaller than that of a monitor, so the security gate is safe, and the pure steel watch will not be magnetized after passing through the security gate.

Car security has no effect on the performance of the watch.

Care of the watch:

Unless a mechanical watch is marked as waterproof, it is important to avoid water entering the case, because water can cause mechanical corrosion and is very destructive. The sea water is even more untouchable. Even if the waterproof watch is indicated, it can only have a year's waterproof guarantee, because the waterproof ring of the watch will be tired after a whole year of wear and tear, plus sweat, dust and other inevitable external factors, so it must be replaced with a new waterproof ring after one year, otherwise it will not have the function of waterproofing.

In addition to waterproof, it is also necessary to prevent collisions. If you can afford it, you may wish to replace two or three watches in your daily life: wear a mechanical watch during static activities, and wear a sports watch when you are engaged in sports, so as to help extend the service life of the watch according to local conditions.

Otherwise, wait until something goes wrong to send it for repair, and the problem is often very serious. It is best to return to your parents' home every year to check whether the mechanical watch has been used improperly or if there is any water. Regular check-ups are very important; Then it needs to be thoroughly cleaned and maintained every three years.

The safest maintenance and repair are safer to be handled by the orthodox ** shop. The cleaning of the interior must be handed over to a professional master, and the cleaning of the exterior may wish to be done by the owner of the mechanical watch himself; Brush the strap with a soft brush dipped in cleaning liquid, and rinse with water.

Water-resistant cases can also be cleaned in this way; Cases that are not water-resistant should never be brushed. It is important to clean the exterior on a daily basis, because sweat, dirt, etc., even if they are too subtle to be noticed, are still accumulating in reality, and if they are not washed, the strap will rust, rot or become brittle. So the owner had better wash it frequently.

Therefore, it is best to take off the watch when washing your face and laundry. When it rains, protect yourself from splashing with rainwater. If it is found that the electronic watch has entered the water, or there is water vapor on the inner wall of the watch, it should be immediately sent to the watch repair shop for water removal and moisture drainage.
