A bit of history. One of the first digital watches I remember was a LED display plastic job from TI, I think. I was delighted to get it back then because I worked on the old disk drives. The access mechanisms on those used a heavy magnetic field (gauss bath was the term then). The magnetic field would instantly destroy an analog watch. Once I got the digital watch, I used to amaze and astound other engineers by taking my watch and dipping it into the magnetic field. It would continue to work with no hesitation. My, how things change!
