@galerna do you wear it while sleeping? It starts from a certain value after turning the watch on (idk how that value is calculated) but its intended use is to wear it overnight where it charges during sleep and then while wearing it during the day it discharges when your active/stressed and sometimes charges again when you’re relaxing enough, e.g. taking a nap. It’s not working correctly when you just use the watch during exercise

@gipfelkind I found the cause: the Morning Report is triggered by arm movement while I’m still in bed. If I don’t see it and leave it undismissed for an hour, it vanishes and cannot be accessed again that day.

@2b2bff optical HR sensors can never be as accurate as measuring the electrical signal with a chest strap. The higher the heart rate, the shorter the R-R intervals, so the measurement error of optical signal detection are a higher percentage of the R-R interval as the HR increases. This throws the math of ZS way off.

I can confirm that too. It has been introduced in latest firmware.

I would like to see a sum of descents (total vertical) on weekly, monthly, and yearly summary. So far, I can only see the distance, which in downhill skiing is pretty irrelevant

Tested today with the Coros HR armband, everything seems fine - firmware du Coros : V1.22.0 [image: 1771852447633-img_0483.jpeg]

@Hugues78fr Yes I understand, that is why I said it is a great idea, and thus i was taking it hypothetically further…very often at a diveresort or liveaboard they show you this drawn card. I would find it a great feature if i could just take a picture and have it on my wrist! The Nautic has an awesome screen…so i guess showing a drawn map or picture for me would be SUPERHANDY If there was ANYTHING on my wishlist that would be it! Tides and maps…tssshhh…i have a phone

@Brad_Olwin “My Plan” is Suunto’s own approach of a training plan, or is it called differently now? I use the iOS app in German translation, what is still a bit lacking…

@SirMcKey @sportsfreund @brad_olwin Thank you! I’m slowly getting back into online things…

@cumbrian-runner hi, yeah, I have the newest firmware as well. I did a hard reset and did a 5km test run, and compared the activity with my old garmin forerunner 255 + polar verity sense arm band. Looks much better now, there are some wobbles here and there (like showing up 10bpm higher in around 18minutes), but overall it is pretty good (162 to 163 bpm average). My 5km run: [image: 1771832282797-zrzut-ekranu-2026-02-23-o-08.26.54.png] Climbing the stairs still not quite good, the HR is updated to proper values only after i stop for a while, and yes I had the watch pretty tight on my wrist and a bit above the bone. And to indicate what was going on before hard reset, one of my walks: [image: 1771832233700-zrzut-ekranu-2026-02-23-o-08.36.55.png]
