How Do Antimagnetic Watches Work?

An antimagnetic watch is a timepiece specifically designed to resist the negative effects of magnetic fields. Magnetism can disrupt the accuracy of traditional mechanical watches by interfering with the movement's delicate components, particularly the balance wheel and hairspring. To combat this, antimagnetic watches incorporate special materials and design techniques to maintain precision even in high-magnetic environments.

How Do Antimagnetic Watches Work?

Antimagnetic watches achieve resistance in several ways:

  1. Non-Magnetic Materials – Key components like the hairspring and escapement are made from silicon, Glucydur, or Nivachron, materials that are resistant to magnetic influence.
  2. Protective Shielding – Some watches use a soft iron inner case to form a protective barrier around the movement, deflecting magnetic fields.
  3. ISO Standards – The International Organization for Standardization (ISO 764) defines an antimagnetic watch as one that can withstand a magnetic field of 4,800 A/m (approximately 60 Gauss) while maintaining accuracy within ±30 seconds per day.

Who Needs an Antimagnetic Watch?

Antimagnetic watches are ideal for professionals who frequently encounter strong magnetic fields, such as:

  • Scientists and engineers
  • Medical professionals using MRI machines
  • Pilots and military personnel
  • Watch enthusiasts seeking enhanced durability and precision

Notable Antimagnetic Watches

Some of the most well-known antimagnetic watches include:

  • Omega Seamaster Aqua Terra >15,000 Gauss – Utilizes a fully antimagnetic movement.
  • Rolex Milgauss – Designed to withstand up to 1,000 Gauss.
  • IWC Ingenieur – Originally developed for engineers working near high-magnetic environments.

Conclusion

If you work around magnetic fields or want a watch with superior resistance to everyday magnetic exposure, an antimagnetic watch is a great investment. With advancements in technology, modern antimagnetic watches offer both high precision and stylish designs, making them a practical and durable choice for any watch enthusiast.
