@zhang965 no I haven’t yet… I think this is a problem with the software and I hope for a fundamental update so that the Vertical’s software finally runs stably. Maybe the memory is full or something similar… ? Even if Suunto were to offer me the exchange of a new watch, I don’t think it would work more stably… I hope for an update soon…I was just interested if other users had observed something similar. That’s only noticeable if you want to do sports and the watch doesn’t find a heart rate. I usually use a heart rate belt and it has always worked.

@jmoneygrip I agree. I also found that the OHR is fairly accurate during activity. It is reasonably close ( at least during trail runs) to what I record on my chest HR monitor. I am satisfied from that standpoint.

What annoys me are all the huge spikes in HR readings at rest and during the night. I do not probably meet the characteristics of the perfect target customer for the S9P; hence, I may care about wellness data from the watch ( and HR reading outside an activity or training) more than the average customer. However I still think this is an issue as these readings may affect sleeping scores and other metrics.

You can hear a flebile ticking if you put it really close to your ear, due to the flashing diode … but buzzing can be an electric issue
