Apple Watch Ultra Altitude and Heading Way Off

My new Apple Watch Ultra originally showed my local altitude exactly right. However, after a flight several days ago, the compass is now off by 70° and the altitude is off by +2,200 feet. The local altitude is 1,380ft. I’ve reset the watch and no change. Anymore else seeing this? As a diver, it makes me question trusting it as a dive watch…

Hello, InvertedPlane.

Did you restart your watch after the flight? If not, please try that now and see if that helps to resolve those incorrect readings: Restart your Apple Watch - Apple Support. Follow these steps:
