There is a lot of discussion around the potential impact of airport security scanners on watches, particularly expensive ones. While some sources claim that x-ray machines can damage watches, others assert that this is a common myth. X-ray machines do not generate magnetic fields, so they will not magnetise your watch. However, some people choose to remove their watches before passing through security to avoid potential issues. This is a cautious approach, especially for those with expensive watches, as there have been reports of watches being stolen during security checks. Ultimately, there is no definitive answer, and it is up to the individual to decide how to navigate airport security with their watch.

What You'll Learn
X-ray machines and magnetization
X-ray machines are used at airport security to scan luggage and sometimes passengers. Some travellers have expressed concern about the potential impact of these X-rays on their pocket watches, particularly whether they can cause magnetization.
X-rays are a form of electromagnetic radiation, and as such, they do interact with magnetic materials. X-ray imaging techniques are used in the field of magnetism research to study magnetic phenomena at the nanoscale. These techniques can reveal the three-dimensional magnetic configuration and dynamics of nanomagnetic structures, providing valuable insights for scientific and technological advancements.
However, the impact of airport X-ray machines on pocket watches may be minimal. Some travellers have reported that their watches have gone through X-ray machines and metal detectors at airports without any issues. On the other hand, there are also reports of watches being affected by airport X-rays, with one user claiming their watch was running 10 minutes fast per month after frequent travel and exposure to X-ray machines.
To minimize any potential risk, some people choose to remove their watches before passing through security. This can be done by placing the watch inside a jacket pocket or another secure location, separate from the items being X-rayed. It is also worth noting that some airports now have full-body scanners that do not require the removal of watches.
While the likelihood of airport X-rays causing significant magnetization in pocket watches is low, further research and user experiences may provide more definitive conclusions.

Metal detectors and beeping
Metal detectors at airports are known to cause watches to beep. This is because the detectors are designed to identify metal objects. While some airports require you to remove your watch, others do not. Some people choose to keep their watch on their wrist throughout the security process to reduce the risk of theft. Others remove their watch and place it inside a jacket pocket or bag, which is then placed in the plastic basket to go through the X-ray machine.
If your metal detector is beeping, it could mean that there is metal nearby. The sensitivity level and discrimination settings of your detector determine the types of metals it can detect, so you may encounter different kinds of metallic objects. Nearby power lines, radio signals, or other electronic devices can also cause interference, resulting in false signals and beeping. Soil composition can also cause false signals, with highly mineralized soil near beaches or volcanic regions increasing background noise and potentially causing consistent beeping.
If you are experiencing constant beeping, you can try moving away from potential sources of interference to see if the beeping stops. Additionally, adjusting the ground balance or sensitivity settings of your detector can help minimize false signals caused by soil mineralization. Consulting the user manual of your metal detector can help you understand the different features and settings that may be impacting its performance.

Watch theft at airport security
While X-ray machines at airport security are not known to affect pocket watches, the security checkpoints are a common place for theft. To avoid becoming a victim of watch theft at airport security, it is recommended that you keep your watch on your wrist or tucked away in a bag or zippered jacket pocket, rather than placing it loosely in a tray. This ensures that your watch is not easily accessible to potential thieves.
Additionally, it is advisable to arrive at the airport early to avoid feeling rushed or flustered at security checkpoints. When travelling with a companion, ensure that one of you has cleared the metal detector before placing your valuables on the conveyor belt, allowing the other person to keep an eye on them. If you are travelling alone, delay putting your valuables on the conveyor belt until you are sure you will be the next person through the detector. Keep a close eye on the conveyor belt and be vigilant in watching for your items as they come out of the X-ray machine.
To further protect your valuables, consider enrolling in TSA Pre-Check or Customs and Border Protection's Global Entry programs, which offer benefits such as expedited security checks and access to baggage claim before your luggage appears on the carousel. Always keep your belongings in sight and, if possible, stay ahead of your luggage as it moves through the security process. Tagging your items with your identification information can also help in retrieving them if they are misplaced or stolen.
Lastly, it is generally recommended to avoid wearing or bringing expensive jewellery when travelling, as it can attract unwanted attention and increase the risk of theft. If you must travel with valuable items, consider investing in secure luggage made of solid and puncture-proof materials, such as PVC or polycarbonate, with clasp closures instead of zippers. By following these precautions, you can significantly reduce the risk of watch theft at airport security.

Body scanners and watch safety
Metal detectors at airports are sensitive and will often react to the metal in watches, jewellery, and even clothing. This is why many travellers choose to remove their watches and place them in a plastic basket to be X-rayed. Some travellers are concerned about potential magnetisation, but this is not an issue, as X-rays will not magnetise watches.
X-ray scanners are used to detect metallic and non-metallic objects, including weapons, explosives, and drugs. There are two main types: backscatter X-ray and millimetre wave. Backscatter X-ray machines use low-dose radiation to create an image of the exterior of a person's body and any objects they are carrying. These machines operate at a much lower energy level than medical X-ray machines, and the radiation dose a person receives is considered negligible and safe. However, there has been some debate about the safety of these machines, and multiple countries have banned their use. In the United States, all backscatter X-ray machines were removed from airports by May 2013, replaced by millimetre wave scanners.
Millimetre wave scanners use low-level radio frequencies to create a 3D image of the subject. Unlike backscatter X-ray machines, millimetre wave scanners do not emit any radiation, ensuring that the person being screened is not exposed to any radiation dose. This type of scanner is the only one used in Canada and is considered safe and effective.
In terms of watch safety, there is no definitive answer as to whether it is better to keep your watch on your wrist or place it in a basket for X-ray scanning. Some travellers prefer to keep their watches on to reduce the risk of theft, while others remove them to avoid setting off metal detectors and causing delays. Ultimately, the decision comes down to personal preference and comfort level with the various types of scanners.

Watch in hand luggage
When travelling with a watch, it is recommended to keep it on your person or in your hand luggage. Many people choose to wear their watch through security, and some airports now have full-body scanners that allow you to do so. However, if you are concerned about your watch setting off the metal detector, you may want to remove it and place it in your hand luggage before going through security.
If you choose to wear your watch, be aware that some metal watches may set off the metal detector, resulting in a wand-down or pat-down. To avoid this, some travellers recommend placing your watch in your hand luggage or a jacket pocket before going through security. This can also reduce the risk of theft, as items placed in trays may be more easily accessed by thieves.
It is worth noting that X-ray machines, metal detectors, and millimetre scanners will not magnetise your watch. However, to be extra cautious, some people choose to wrap their watch in a protective material, such as a laptop bag or a jacket, before placing it in their hand luggage. This can provide additional protection and make it less obvious that you are carrying a valuable item.
Ultimately, the decision of whether to wear your watch or place it in your hand luggage is a personal one. Consider your own comfort and the security measures at the airport you are travelling through. If in doubt, you can always contact the airport or your airline directly to inquire about their specific policies and recommendations regarding watches in hand luggage.
