That’s pretty crazy. Anecdotally and what I assumed was the case, everyone I’ve talked to has said the heart rate monitoring is pretty worthless. At least before the last 2 iterations. Maybe they’re better.
The first time this happened, I was wearing a Series 3 Watch, and the last time it happened, I was wearing the Series 5. It's accurate enough to know from daily wearing/monitoring, that my heart rate was irregularly elevated. That's enough for me.
Ah okay. I get incredibly anxious and my heart rate spikes during those times. But Series 1 or 2 (not sure which I have) has never reliably noticed. I might be getting Series 4 this year since they stopped manufacturing it. Will see how it goes then. Thanks.
