You might recall that in the movie X-Men: Dark Phoenix (2019) there is a scene where you can see Professor X talking to Magneto. If you look closely, he is wearing a Rolex Milgauss around his wrist. This watch is actually known for resisting magnetic fields up to 1000 gauss (hence the name), a unit used to measure magnetic fields. And while the watch was first designed and created in 1956, this Rolex is still available today, which will hardly come as a surprise if it’s really that resistant.
