High heart rate values

Tightening the band is unlikely help. Loosening it might... the sensors can work even when rested on the wrist using only the weight of the watch to hold it on your arm.

I didn't have it that tight, but good point. Resting the watch on my arm under its own weight only doesn't help either. But I did find that if I hold the watch and move it up and down off my wrist about once per second I can get it to read 60bpm.
