I also have the same issue. 9pp running 2.50.28 and many times over the last year or more wrist heart rate stops. Green leds not flashing. Turn off turn on to fix but you only realise it’s stopped when you synch in the morning. Night sleep, recovery all inaccurate. I have no good reason to buy Suunto again ️

It’s been happening to me for 2 days now. The first time I didn’t pay much attention to it, but yesterday’s was more “fun.” In the middle of an interval workout, the watch decided to restart itself, ending the activity. When I noticed, I started the same activity again with the same interval workout, and to my surprise it restarted itself two more times. In addition to the activity, I was also using a COROS HRM. I’m trying to send the logs, but the app freezes and won’t even let me send them… a complete disaster.

@Kajkom Yes, it matches. But that doesn’t seem like it’s connected to the issue. The watch counts correctly all the way up until you save/finish the workout, at which point it discounts it 3.75%.

@estragio Looks interesting, but still no dive counter

"if you don’t end your activity… " Yes but I did end it and was in trouble. All your answers make no sense and don’t address the point: Who is the genius in Suunto who decided you need to download tracks to a phone and then upload them back in order to be able to follow them on the watch? The data is already in the watch, let me use it, please! And besides, the battery of my watch outlasts the one of my phone, so the situation was not unexpectable (some of you who answered would probably come up with this great solution: make the battery of the watch last less
