What Is an Anti-Magnetic Swiss Watch?

The Takeaway:

Ever had that experience where for some weird reason, your watch just stopped working? Well, you might see this in sci-fi movies where unidentified flying objects (UFO) near the area cause clocks and watches to stop. UFOs or not, the reason for this is magnetism. For this reason, Swiss watch companies developed Anti-magnetic watches.

Its history dates back to 1846, where experiments done to create anti-magnetic watches were first recorded. It was Vacheron Constantin, a premier watch-making company who had first done the study and experimentation. However, it was only decades later until it was actualized. They were able to develop a watch that can endure magnetic fields because they used non-magnetic metals. They used the metal Palladium for their balance wheel, balance spring, and lever shaft, making these watches still able to function even within or after high magnetism.

Charles Edouard Guillame was the one who discovered Invar and Elinvar, nope they are not islands, but nickel-based alloys that are able to withstand magnetic fields allowing a watch to remain accurate. Other alloy-based materials also include Glucydur and Nivarox, which were widely used by watchmakers in the 1950’s.

Aside from using alloys, another method of producing non-magnetic watches is by using a highly conductive material to house the movement inside a case.

As mentioned earlier, it was Vacheron Constantin that first developed these watches; in 1915, they introduced the first anti-magnetic pocket watch. It was then followed by Tissot’s non-magnetic wristwatch in 1920, and then the first anti-magnetic chronograph by Vacheron Constantin in 1954. The company Jaeger Lecoultre improved the chronograph’s design and improved its resistance by doubling-up the case.

Today an international standard, which is the ISO 764, dictates that this type of watch should be able to sustain itself from direct current magnetic field exposure of 4,800 Ampere per meter. It also states that it should maintain its accuracy to give or take 30 seconds/day as calculated before the test for it pass as a magnetic-resistant watch. An additional soft-iron clasp is also used to cover the movement to ensure that magnetic fields are not formed inside the watch.

These additional features have driven Swiss watch brands

 to produce their own watches for better time-telling performance despite other disturbing factors. Other companies that also developed their line of this type of watches include Omega, Patek Philippe, and IWC.

This type of watch is best for those who are frequently exposed to high magnetic fields such as scientists, engineers, and other professions that are vulnerable to it. The Milgauss model, in particular, produced their 6541 model for those working in strong magnetic fields in the medical, nuclear, and aircraft fields. Nowadays, diving watches are also required to be made like this and among other specifications.

These new discoveries sure improved the quality and utility of Swiss watches, making them all the more likable among those who want sophistication and impressive function in a watch.

The creation of the anti-magnetic watch is another creative genius that makes Swiss watches
