Compass or altimeter on your watch not calibrating properly

Compass and altimeter problems are caused by metal or magnets near the watch throwing off the sensors. Move away from anything metal, go outside into open space, and recalibrate. This fixes it.

Your watch has tiny sensors that detect Earth's magnetic field and air pressure to figure out direction and altitude. When metal or magnets are close by, they scramble those sensors and give wrong readings. Outdoor calibration away from anything metal lets the sensors find true north and altitude again. If the sensors themselves are damaged from a drop or water exposure, recalibration won't help.
