Indoor Swimming activity - My 955 crashes after resuming

I have noticed a strange behaviour of my 955 since last firmware update.

I often use the indoor swimming activity (set to 14m), after 10min of swimming I make a 5min brake then go again for 10min swimm and them make again about 11min brake and then go again for 10min swimm. (During the brakes the watch goes automatically to idle mode)

Now, ever time after the 11min brake I start swimming and after several meters the watch crashes completely and make a full restart - I tested this already 3 times so it seems to me as quite a regular behavior. 

Garmin, is this issue know?

  • Recently, I installed version 26.08, but I can’t remember the exact day.

    I went to the pool this Wednesday, and I swam almost non-stop for 40 minutes without anything unusual happening.

    Today, unusually, I focused a lot on leg work, and as a result the watch thought I was taking a break and the rest timer kept increasing.

    After a while, when I looked at my watch, the activity had stopped and the regular watch face was displayed.


    I restarted it and noticed the same thing after about ten minutes.

    This time, I saw a Garmin logo, and then the watch face appeared again.

  • Yep, same for me. 4th crash during drill mode, now even after reinstalling the software. Very disappointing!
