I have a Fenix 6 Sapphire and am stumped concerning the altimeter/barometer functions.
I'm a former air traffic controller so I fully understand the relationship between the two functions however, whatever watch face I use, it is the altimeter that changes (even if altimeter is not on the display) while barometric pressure remains the same. I understand why the altimeter is changing - it's responding to pressure changes - but if I'm not moving from home it shouldn't change. If I calibrate the functions and set my home elevation, it rights itself and the new pressure is correctly shown.
It's pressure that changes over time not the altimeter (assuming I'm staying in the same place). But on my watch, the pressure display is unchanging - it's just the altimeter that changes.
Puzzled!
