Yeah I though about that when writing it. I don't know.

What I do know is I used to wear a Tissot T-Touch which has a compass, and it doesn't work everywhere. Not in underground car parks, and certainly not on airplanes.

Maybe it's specific to the Tissot, I'm not sure.

Maybe they are using GPS as a compass?

This. Many mobile, or even vehicle (GPS) compasses are not magnetic at all, but are doing point to point math on your GPS coordinates to "determine" your compass heading.

A compass is influenced by anything that disturbs the local magnetic field: magnets, metal objects, electrical currents, etc.
