I had the issue and they replaced mine. It was showing my altitude at 50k feet. Haha, my TSS was off the charts

Same with my 935 that was only a few months old. New one on the way!

I got mine in December 2016. I'm guessing that's well out of warranty... this is too stupid, though. If I could just turn the altimeter off, that'd be fine. I mean, not great that the altimeter didn't make it 3 years, but it's not like I know anything about altimeters and how long they tend to last. But they should just put a setting in garmin connect that would let you turn it off.

Turns out you can 'correct' the altimeter in strava as well. good to know, since i go there much more often than i go on garmin connect.

You can’t fix it. I have had 6 of the 935 go bad on me From Oct tell now. Called on Monday to get another one and they upgraded me to the 945. They are back ordered for 2 more weeks with AG Nationals and IMMT coming up , just great!!

I've sent 3 back, do you swim a lot? I do and I swear the chlorine damages the barometer sensor.

I swim around 4-5 times per week. I think you are right that the chlorine kill the barometer. I used the 920 and had no problems and the 935 I have nothing but problems. It’s ridiculous that you have to baby it so much

Now i use a 735 to swim since there is no barometer hole, and the 935 for running and cycling. I had the same trouble with the 920.

Haha. The real Q...Anyone's else's Garmin altimeter still working?

The latest, from Garmin:

"So, we would be looking at a replacement on this. The device is out of warranty and you would be looking at $120 plus tax for a newly overhauled unit. These come with a 90 day warranty on them.

Thank you for choosing Garmin,"

pretty weak IMO...


I'll probably replace the watch this fall. The GPS on this wasn't accurate enough to just get the same thing again...

Got the same email from Garmin Support. $160 to replace my Fenix 5 with a refurb.

Not sure I want to spend more money to fix something that is really just an annoyance. I'm like you I wish I could just disable it completely. And if I do get a new watch I'd rather upgrade to something actually new. IDK.

my 820 isn't a total mess - but is nowhere close to accurate. Consistently have the same start and finish but climb hundreds of feet less than descend. Correctable in GC - if i remember or care enough

My 920 generally calculates my first mile with about 22,000 feet of elevation (I live in VA Beach elevation maybe 20 feet above sea level), after the first mile it returns to normal.

I am a new victim of the altimeter going bad on my Garmin Forerunner 935. I purchased mine when the 935 was new and hot on the shelves a couple of years ago. I have been wearing it daily to count flights of steps I complete (I climb a lot of flights daily). Only in the past week or so it started to go bad. Today it read 0 flights after I climbed at least 10 flights. I went through Garmin customer service chat - total 10 minutes. They did the Baro test too. My Baro Temp read 288.9. They are expediting the replacement - everything at no cost - since I have a race coming up in 2.5 weeks. I have to say I LOVE Garmin customer service.

One thing Garmin mentioned that could break the altimeter was wearing it in a hot tub or pressing the buttons a lot underwater. I have worn mine into the hot tub for a few minutes after my swim workouts. They will replace it regardless.

A swim watch that breaks in water. Brilliant.

My altimeter never worked. I bought it right before IM Boulder last year and it had some outrageous elevation totals. Even runs with almost no elevation change will show thousands of feet. As long as it isn't used to calculate workload, VO2 max, etc, then it doesn't bother me that much.
