If Magnets Are Not a Real Concern, Then Why Do Garmin Emphasize Caution?

I ran across this set of Warning and Notice in the Marq Aviator (Gen 2) Owner's Manual:

Evidently, magnets are contained in BOTH the watch case and the charger cradle.  And further, these magnets are evidently strong enough to be a potential concern if placed too close to medical devices, LAPTOP HARD DRIVES, and other electronic devices.

I assume (i.e. maybe correctly, maybe incorrectly) that Garmin have taken the presence of a powerful magnet in the watch case into account when managing Compass calibration, but is it still a concern?

Anyone with a MARQ (Gen 2) have any experience with magnetic interference?

Am I blowing this out of proportion?

Anyone care to talk me off the ledge?
