Myheart rate is low, due to a congenital heart defect, I tried a FitBit and it wasn't as reliable as I'd like, how accurate is the Apple Watch? I have usually a resting rate in the mid 40's and asleep as low as 28-30bpm. I'd like an accurate monitor, but 'attempting' with a $300 device...
Hi
Consumer Reports tested the Apple Watch heart rate sensor against their highest-rated dedicated heart rate monitor and found "no significant differences" between their readings:

However, note that Apple Watch, the heart rate sensor and the included apps are not medical devices and are intended for fitness purposes only. They are not designed or intended for use in the diagnosis of disease or other conditions, or in the cure, mitigation, treatment, or prevention of disease.
