Quartz watches are known for their accuracy and reliability. However, like any other watch, they can become magnetized. Magnetization can cause the watch to run fast or slow, affecting its accuracy. Quartz watches use a tiny magnetic stepper motor that is susceptible to magnetism. When exposed to a magnetic environment, the force can cause the watch to become magnetized.
While quartz watches are less susceptible to magnetization compared to mechanical watches, it is still a possibility. The good news is that quartz watches are easier to demagnetize compared to mechanical watches. Demagnetizing a quartz watch involves using a demagnetizer tool or taking it to a professional watchmaker. Once demagnetized, the watch should return to its normal functioning state.
What is Magnetism?
Magnetism is a phenomenon that occurs when a material or object produces a magnetic field. This field is created by the motion of electrons within the material or object. Magnetism is a fundamental force of nature and is present in many everyday objects, including watches.
A magnetic field is an invisible force that surrounds a magnet or a moving electric charge. It is represented by lines of force that indicate the direction of the field. Magnetic fields can be created by magnets, electric currents, and even the Earth itself.
The strength of a magnetic field is measured in units of Gauss or Tesla. One Gauss is equal to one line of magnetic flux per square centimeter, while one Tesla is equal to 10,000 Gauss. The Earth’s magnetic field is approximately 0.5 Gauss, while a typical refrigerator magnet has a strength of around 100 Gauss.

How Magnetism Affects Watches
Magnetism can have a significant impact on the accuracy of a watch. In mechanical watches, the balance wheel and hairspring are particularly susceptible to magnetization. When these parts become magnetized, they can stick together, causing the watch to run too fast or too slow.
Quartz watches can also become magnetized, although they are less susceptible than mechanical watches. The tiny magnetic stepper motor used in quartz movements can be affected by strong magnetic fields, causing the watch to run inaccurately.
If a watch becomes magnetized, it can usually be demagnetized using a demagnetizer. However, it is important to avoid exposing watches to strong magnetic fields whenever possible to prevent magnetization from occurring in the first place.
How Quartz Watches Work
Quartz watches are powered by a tiny magnetic stepper motor that drives the movement of the watch hands. The motor is powered by a battery and regulated by an electronic oscillator that vibrates at a precise frequency. The frequency of the oscillator is used to measure time and is controlled by a quartz crystal. The quartz crystal is an important component of the watch and is responsible for the accuracy of the watch.
Why Quartz Watches are More Resistant to Magnetism
Quartz watches are less susceptible to magnetism in comparison to automatic and mechanical watches. This is due to fewer metallic and moving parts and the fact that the quartz doesn’t retain the magnetism unlike other types of movement. Also, the motor is found deep inside the core and most top pieces have a casing that is more resistant. However, quartz watches can still become magnetized when exposed to strong magnetic fields, such as those found in MRI machines or near powerful magnets. When this happens, the watch can become inaccurate, and the hands may stop moving entirely.
According to odm, “quartz movement uses a tiny magnetic stepper motor that is susceptible to magnetism. Hence, the watch can become magnetized when exposed to a magnetic environment due to the increased force.”
If you suspect that your quartz watch has become magnetized, you can take it to a watchmaker or jeweler who can demagnetize it using a demagnetizing machine. Alternatively, you can purchase a demagnetizer and demagnetize the watch yourself. However, it is important to note that demagnetizing a watch incorrectly can cause permanent damage to the movement, so it is best to leave it to the professionals.
Can Quartz Watches Become Magnetized?
Quartz watches are known for their accuracy and reliability. They are less susceptible to magnetism compared to automatic and mechanical watches. However, quartz watches can still become magnetized under certain circumstances. This section will discuss the factors that cause magnetization, symptoms of magnetization, and how to demagnetize a quartz watch.
Factors that Cause Magnetization
Quartz watches can become magnetized when they are exposed to strong magnetic fields. This can happen when the watch comes into contact with magnets in everyday objects such as speakers, cell phones, and laptops. The magnetic field can interfere with the movement of the watch, causing it to run fast or slow.
Another factor that can cause magnetization is the proximity to electronic devices such as MRI machines. Quartz watches should be removed before entering an MRI room or any other environment with strong magnetic fields.
Symptoms of Magnetization
The symptoms of magnetization in quartz watches are similar to those in mechanical watches. The watch may run fast or slow, or it may stop altogether. The hands of the watch may also move erratically or jump in small increments. If you notice any of these symptoms, it is likely that your quartz watch has become magnetized.
How to Demagnetize a Quartz Watch
Demagnetizing a quartz watch is a simple process that can be done at home or by a professional watchmaker. To demagnetize a quartz watch, you will need a demagnetizer. A demagnetizer is a small device that emits a magnetic field in the opposite direction to the one that has magnetized the watch. This cancels out the magnetic field and restores the watch’s accuracy.
If you do not have a demagnetizer, you can take your watch to a professional watchmaker. They will use a demagnetizer to remove the magnetism from the watch. It is important to note that demagnetizing a quartz watch is a delicate process that should only be done by a professional. Attempting to demagnetize the watch yourself could cause further damage to the movement.
In conclusion, while quartz watches are less susceptible to magnetization compared to mechanical watches, they can still become magnetized under certain circumstances. If you notice any symptoms of magnetization, it is important to take your watch to a professional watchmaker for demagnetization.
Avoiding Magnetic Fields
One of the best ways to prevent magnetization of quartz watches is to avoid exposing them to magnetic fields. Magnetic fields can come from a variety of sources, such as cell phones, speakers, and magnetic clasps on bags or clothing. It is important to keep your watch away from these sources to avoid magnetization.
If you work in an environment with strong magnetic fields, such as a laboratory or near MRI machines, it is recommended to wear a watch with a non-magnetic movement, such as a quartz watch. However, it is still important to take precautions and avoid exposing the watch to strong magnetic fields.
Storing Watches Properly
Proper storage of quartz watches can also help prevent magnetization. When not in use, it is important to store the watch in a safe place away from magnetic fields. This can be done by keeping the watch in a watch box or drawer, away from other magnetic objects.
It is also recommended to store the watch with the crown in the closed position. This helps prevent dust and moisture from entering the watch and potentially affecting its movement.
Regular maintenance of quartz watches can also help prevent magnetization. This includes having the watch serviced every few years by a professional watchmaker. During the service, the watchmaker can check for magnetization and demagnetize the watch if necessary.
It is also important to keep the watch clean and dry. Moisture can affect the movement of the watch and potentially lead to magnetization. If the watch gets wet, it is important to dry it off immediately and have it serviced if necessary.
Quartz watches have become increasingly popular in recent years due to their accuracy and affordability. They are powered by a battery and use a quartz crystal to keep time, which makes them less susceptible to magnetization than mechanical watches. However, despite their resistance to magnetism, quartz watches can still be affected by strong magnetic fields.
Magnetic fields can cause a quartz watch to run fast or slow, which can be frustrating for the wearer. While quartz watches are generally less prone to magnetization than mechanical watches, they can still be affected by magnets found in everyday objects such as smartphones, laptops, and speakers. This is because the electronic components in these devices can produce strong magnetic fields that can interfere with the quartz crystal’s oscillations.
What are Quartz Watches?
Quartz watches are timepieces that use a quartz crystal oscillator to keep time. They are powered by a battery and are known for their accuracy and affordability. Quartz watches were first introduced in the 1960s and quickly became popular due to their reliability and ease of use.
History of Quartz Watches
The first quartz watch was developed by Seiko in 1969. It was called the Seiko Quartz Astron and was the world’s first quartz watch. The introduction of quartz watches revolutionized the watch industry and made accurate timekeeping affordable and accessible to everyone.
How Quartz Watches Work
Quartz watches work by using a battery-powered electronic oscillator to vibrate a quartz crystal. The crystal vibrates at a specific frequency, which is used to regulate the timekeeping of the watch. The oscillator sends an electrical signal to a microchip, which then converts the signal into a series of pulses that move the watch’s hands.
Quartz watches are less susceptible to magnetism in comparison to automatic and mechanical watches. This is due to fewer metallic and moving parts and the fact that the quartz doesn’t retain the magnetism unlike other types of movement. Also, the motor is found deep inside the core and most top pieces have a casing that is more resistant. However, analog quartz watches utilize the power of magnetic force in order to drive the step motors to move the rotors. These step motors are extremely small and may easily be affected by magnetism, which may impact the rotor. As a result, watches may stop or fail to keep correct time.
What is Magnetic Resistance?
Quartz watches are known for their accuracy and reliability, but they are not immune to the effects of magnetic fields. Magnetic fields can cause the watch to run fast or slow, which can be frustrating for the wearer. To combat this issue, watchmakers have developed watches with magnetic resistance.
Magnetic Fields and Watches
Magnetic fields are all around us, and they can come from a variety of sources, such as electronic devices, magnets, and even the earth itself. These fields can interfere with the operation of a watch, causing it to run too fast or too slow. Quartz watches are particularly susceptible to magnetic fields because they use a battery-powered electronic movement.
When a watch is exposed to a magnetic field, the magnetic force can cause the components of the movement to become magnetized. This can cause the balance wheel to stick, which affects the watch’s accuracy. The higher the magnetic field, the more significant the effect on the watch.
Why Magnetic Resistance is Important
Magnetic resistance is essential for watches that are worn in environments with high magnetic fields, such as near electronic devices or medical equipment. Without magnetic resistance, the watch’s accuracy can be compromised, leading to frustration for the wearer.
Quartz watches with magnetic resistance use a variety of techniques to protect the movement from the effects of magnetic fields. One approach is to use a non-magnetic material for the movement, such as silicon. Another method is to shield the movement with a soft iron inner case that attracts the magnetic field lines, leaving the movement unaffected.
It is essential to note that not all quartz watches have magnetic resistance. When shopping for a watch, it is essential to check the specifications to determine if the watch has magnetic resistance and to what level. The international standard ISO 764 defines basic magnetic resistance for watches. They must resist exposure to a direct current magnetic field of 4,800 amperes per meter and keep precision to ±30 seconds a day.
How Quartz Watches Achieve Magnetic Resistance
Quartz watches are known for their exceptional accuracy, but they are also susceptible to magnetic fields. To achieve magnetic resistance, watchmakers use a combination of magnetic shielding and anti-magnetic materials.
Magnetic shielding is a technique used to protect the movement of the watch from external magnetic fields. This is done by encasing the movement in a layer of soft iron, which is a highly magnetic material. The soft iron attracts the magnetic field, creating a path of least resistance and diverting the magnetic field away from the movement. This effectively shields the movement from the magnetic field.
The soft iron shielding is often placed inside the case of the watch, surrounding the movement. This provides an additional layer of protection against magnetic fields. Some watchmakers also use a Faraday cage, which is a type of shielding made of conductive material that blocks electromagnetic fields. The Faraday cage is usually made of copper or brass and is placed around the movement.
Another way that quartz watches achieve magnetic resistance is through the use of anti-magnetic materials. These materials are designed to resist the effects of magnetic fields and are often used in the construction of the movement.
One of the most common anti-magnetic materials used in quartz watches is Nivarox, which is a nickel-iron alloy. Nivarox is used in the hairspring, which is a crucial component of the movement. The hairspring is responsible for regulating the rate at which the watch keeps time, and it is highly sensitive to magnetic fields. By using Nivarox, watchmakers can ensure that the hairspring is resistant to magnetic fields, which helps to improve the accuracy of the watch.
Other anti-magnetic materials used in quartz watches include silicon and synthetic diamond. Silicon is often used in the escapement, which is another important component of the movement. The escapement is responsible for transferring energy from the mainspring to the balance wheel, and it is also highly sensitive to magnetic fields. By using silicon, watchmakers can ensure that the escapement is resistant to magnetic fields, which helps to improve the accuracy of the watch.
Advantages of Quartz Watches with Magnetic Resistance
Quartz watches are known for their accuracy, and this is especially true when it comes to magnetic resistance. Unlike mechanical watches, quartz watches are not affected by magnetic fields, which can cause significant timekeeping errors. This is because quartz watches use a battery-powered quartz crystal to regulate the timekeeping, rather than relying on the movement of gears and springs.
Additionally, many quartz watches with magnetic resistance are equipped with advanced features like chronographs, alarms, and timers, which can be useful for a variety of activities and professions.
Quartz watches are generally more durable than mechanical watches, and this is especially true when it comes to magnetic resistance. The internal components of quartz watches are typically made from materials that are less susceptible to magnetization, such as synthetic rubies and ceramics. This means that quartz watches are less likely to be affected by magnetic fields, which can cause damage to the movement.
Furthermore, quartz watches are often more affordable than mechanical watches, making them a practical choice for everyday wear. They also require less maintenance, as they do not need to be wound or serviced as frequently as mechanical watches.
Disadvantages of Quartz Watches with Magnetic Resistance
Quartz watches with magnetic resistance tend to be more expensive than those without. The additional technology and materials required to make the watch magnetic-resistant can add to the cost. In addition, the manufacturing process of magnetic-resistant watches is more complex, which can increase the price even further.
While quartz watches with magnetic resistance have many advantages, they also have some design limitations. The additional materials and technology required to make the watch magnetic-resistant can make the watch bulkier and heavier than non-magnetic-resistant watches. This can limit the design options available to watchmakers.
In addition, the magnetic-resistant materials used in quartz watches can limit the range of colors and finishes available. Some materials may not be suitable for use in magnetic-resistant watches, which can limit the design options available to watchmakers. This can be particularly challenging for luxury watch brands that strive to create unique and distinctive designs.
Finally, the magnetic-resistant materials used in quartz watches can also limit the ability to create certain features, such as transparent case backs. Magnetic-resistant materials are often opaque, which can prevent watchmakers from showcasing the intricate inner workings of the watch.
