Recently while skiing, I noticed that the barometer of my Forerunner 265 was not reporting lower pressures as I would expect on mountains. The altimeter gave me numbers that made sense, but the barometer constantly reported numbers slightly above 1000 mbar (I was well above 3000m). Furthermore, on a recent flight, I observed that the pressure on my watch was not dropping. My phone, which I generally trust less than my watch, strongly deviates from the numbers on my watch.
Could the barometer on my watch be clogged?
Has anyone experienced such a problem before?
How do you clean the barometer? I have tried water, but that didn't help.
