For decades, the best watchmakers in the world have lost sleep over how they can make their timepieces anti-magnetic. Even luxury watches crafted using premium materials are affected by magnetic fields, in fact, in some strong cases, the watch can stop working altogether.
Magnetic fields stronger than 50 -100 gauss can adversely impact the precision of an analog watch. How so? Well, the magnetic fields can effectively magnetize the miniscule hairspring and shorten it. Other intricate inner parts may also become magnetized and start to gravitate towards one another, thereby increasing friction and expedited wear and tear.
Does not sound like much of a problem? Well, even if you aren’t a scientist at the CERN institute in Geneva who is exposed to strong magnetic fields for long hours, you could still be around magnetic fields that can take a toll on your watch. And if you have a penchant for fancy watches, this could become a real problem. Remember, everyday devices like speakers, magnetic phone cases, monitors, etc. have the ability to magnetize the tiny hairspring in your luxury watch.
Watchmakers now have a solution for this expensive annoyance. Welcome to the world of anti-magnetic watches. They come with an in-built, protective Faraday Cage which soaks up the magnetic field and prevents the contents within the cage from becoming magnetized.
Want one of these bad-boys? Here are a few of the fastest selling magnetic watches on the market today.

Rolex Milgauss: Honouring Science
Milgauss watches from Rolex are one of the most popular magnetic watches in the market today. Mille in French is ‘thousand’, and the aptly titled Milgauss can withstand a magnetic field of up to 1000 Gauss.
Take a peep at the wrist of a scientist working at the European Organization for Nuclear Research (CERN) in Geneva, and you will likely notice magnetic watches: Rolex Milgauss specifically.
At this time, Rolex offers two timeless looking Milgauss models. First, we have the Oyster perpetual Milgauss with a breath-taking Z-blue dial and luminescent hour markers, and a green crystal to produce light reflections.
The green sapphire crystal is a Rolex creation, which is unique, scratch proof and fade-proof. It is exclusively available on the Milgauss.
The other model of the Milgauss features a black dial, but also includes the luminescent hour markers and the green sapphire crystal.
The seconds hand on the Milgauss is stunning too. It is an evocative orange which is lightning – bolt shaped.
With such a high resistance to even a strong magnetic field and looks that are timeless, it is not surprising that the Rolex Milgauss is a leading anti-magnetic watch in the market today.
IWC Ingenieur Automatic
The original Ingenieur was completely anti-magnetic, but in the currently available series it is only the IWC Ingenieur Automatic model which is protected from magnetic fields up to 501.6 Gauss. This watch is designed by Gerald Genta whose creations featured in classics like the Royal Oak and Patek Philippe Nautilus.
Panerai Luminor Submersible 1950 Amagnetic
Panerai watches are known for being bigger in size than most luxury watches. This makes it the perfect candidate to house a Faraday Cage which can protect the intricate parts of the watch from magnetic fields up to 501.6 Gauss. The Panerai Luminor Submersible 1950 Amagnetic is the only Panerai watch that is anti-magnetic.
Omega Seamaster 300 Master Co-Axial
The Omega Seamaster 300 Master Co-Axial is also an anti-magnetic watch, but what makes it unique is that it does not use a Faraday Cage. In fact, it uses silicon and other magnetic conductive materials that aren’t soft iron. This watch can take literally any magnetic field, but the rating is only up to 15,000 Gauss. This is simply because it is not possible to test it by subjecting it to a stronger magnetic field, since we cannot create stronger magnetic fields at this time.
