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.

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.
- cmdrfred 10y agoMaybe they are using GPS as a compass?
- FireBeyond 10y agoThis. 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.
- pge 10y agoA compass is influenced by anything that disturbs the local magnetic field: magnets, metal objects, electrical currents, etc.
