That's why railway workers back in the late 19th through mid-20th centuries needed to get their pocket watches inspected every 15 days. Those watches were regulated to 5 or 6 positions, temperature (necessary in the cab of a steam locomotive), and isochronism. Anti-magnetic properties were required once diesel--electric locomotives were in use.
