Sunday RewindA Rolex Milgauss, An Omega >15,000 Gauss, And A 4,000 Gauss Neodymium Magnet

Magnets and watches don't mix, and many of us have had the experience of having a watch become suddenly inaccurate (or non-functioning), only to be later told by a watchmaker that it had become magnetized. As with all things invisible, the level of general understanding surrounding magnetism and watches is varied and mostly characterized by the fear of anything magnetizing your watch - be it the x-ray machine at the airport, your laptop at work, or even your own fridge. In an attempt to quell such concerns, Jack goes hands-on with a couple of very anti-magnetic watches and a seriously magnetic, well, magnet. 

In this post from 2016, Jack offers a crash course in magnetism and then tests a couple of watches on a hugely powerful magnet. It's a detailed and thoughtful look at a real-life issue in watchmaking that has only increased with severity as we've increased the amount of magnetic interference in our modern environments. But, as Jack illustrates in the post, some watches deal with magnetism better than others.
