I still dont get how this is possible. Maybe I am wrong, but I thought that the device, watch (not only Suunto) works as the recorder of data, and those are moved to app for further processing. The more sofisticated calculation happens in the app, and basic ones on the device and/or app using the same algorithm. Why other brands do not experience these issues?

I have been studying, testing, and comparing optical sensors for 10 years. I know very well how they work and I understand the difference between a malfunction and a reading error. I did not report a reading error. I did not report suboptimal conditions. I did not report inaccurate heart rate readings. This report is about a crash/shutdown at rest without any clear reason. The sensor suddenly turns off without warning, even though the conditions in which it was previously working have not changed. I have used the following wrist-based optical sensors over the past 15 years: Garmin Fenix 3 HR Garmin Fenix 5X Garmin Fenix 6X Suunto Vertical 1 steel no solar Suunto Vertical 1 titanium solar second Suunto Vertical 1 titanium solar Garmin Fenix 7X Suunto Vertical 2 Garmin Fenix 8 Garmin Vivosmart 4 Garmin Vivosmart 5 Whoop 4 Whoop 5 (Basically the entire Elevate lineup) This shutdown issue occurs only with the Vertical 2.

@Elipsus Too sluggish and too many “scores” and other smart-nonsense. Maybe future Enduro 4?

@Thaler-Martin Could you please use English as it is the forum language? I believe it is easier nowadays with all the tools we have. Thank you.

@radum I experience the same with walking. HR is around 90 BPM on straight road, then I start climb uphill and even I feel that the HR goes up, the watch still shows values around 90 BPM. Usually it is enough to stop for a while until watch recognizes increased HR and after that it seems as the OHR works ok. It may be some kind of cadence lock but even I tried to tighten the strap, move watch on the hand, it behaves the same. Mostly just the pause for a while helps the watch to recognize increased HR.

@isazi Yes that’s true and that’s why I shiftet to other HR from COROS and Polar. But if I select the suunto belt on the watch before a workout, the watch should keep catching the signals of the selected sensor It seems to me that the sv2 has a problem with handling the signal and priorizing As I said it worked very fine without the suunto belt and with different other HRs before the update tragedy that startet in Novemwr when the watch got trouble on IOs machines. But that is another point

@brave_dave No, fortunately I don’t experience continuous disconnection issues. It only happens in water due to the physical limitations of Bluetooth transmission. When the arm comes out of the water, the connection is restored automatically without any problems. At least with the Vertical 2. Which device are you using?

@isazi Könntest du mir bitte meine Frage in englisch übersetzen? Das wäre super… Ich habe immer den automatischen Übersetzer ins Deutsch eingestellt somit kann ich alles lesen…aber ich kann nicht englisch schreiben…

@Pep-Carbonell I hope Suunto roll this feature out to all watches that can support it in the near future.

@DirkJ after an update all logbook activities are deleted, only the summaries are left

@prakalejas a firmware update should come before summer as far as I know

@isazi the sdk is so easy to work with that I wouldn’t be surprised that this is the case. I’m so happy with the watch itself and the general software experience so this is essentially the last puzzle that allows getting rid of other platforms and consolidating everything sports/longevity related around my suunto

@dg2288 Welcome. I agree (we surely all agree ) with sportsmode backup restore interest. For the sharing from others, argh… Are we really in this world where we need (want) to copy each and every things from others and not experiment by ourselves our own (personal) needs? No offense, I imagine that there could be some marketing interest for this, but not for my personal usage.

@Ioannis-Christodoulou and you have a stuck shift key on your keyboard…

@jjpaz thank you! I added your information

@safari Uh, but do they actually monitor: Running Dynamics: step cadence, total steps, and vertical oscillation. Running Symmetry: balance between your left and right feet by comparing ground contact time. Activity Stats: records ascent and descent (elevation changes), estimated calories, and the total duration of the workout. Cervical Mobility Assessment: perform a test where you move your head (up/down and side-to-side) to measure the symmetry of movement between your left and right sides ? There’s no mention here

@NorthStarFY26 personally I think, that Ocean is one of the best looking watches, Suunto has ever made If you buy it for the features it has today, you won’t be disappointed by the slow update cycle Ocean has. I can confirm, that it is actively developed. It is just always behind the update schedule of the other sport watches.
