FENIX 7X sapphire solar my altitude continually is incorrect.

FENIX 7X sapphire solar my altitude continually is incorrect. I reset it manually. I continue to try to reset it via GPS and the other available reset options. And it is consistently incorrect. Any suggestions? Thanks

  • Same issue here with the 7x Pro. Calibrate it, couple hours later it had drifted again. This morning at 4am it 'calibrated' itself to -18m from where I'm at. 

    Best part is, I had 3 Epix Pros before this Fenix, and they ALL did the same thing after a week. Altitude is perfect the first week, then it goes to ***. Garmin support just gives me a new watch every time but it's obviously a software issue if it can be fine for a week. 

  • Got the exact same issue with my instinct 2x, it was fine when the watch was new but after a couple of weeks the altimeter is going to drift. If I lay my finger on the gps button it is enough to let the altimeter start drifting
