I know this is pretty much a scientific fact but I tested my wrist rate monitor on my Garmin with a chest heart rate monitor that synced to a treadmill and there was no discernible difference over multiple two hour+ runs. I think either exactly the same average or off by a beat or two max despite no connection between the two monitors.
I might look at my wrist and see it says 142 while my treadmill way say 137 for a second but then my wrist one will catch up. It's almost like it was just 'delayed' by about 5 seconds and otherwise was the exact same. There's blips here and there if I were to chart them but I was surprised just how close they were.
Either the wrist heart rate monitor is better than "advertised" or it's inaccuracy was somehow able to align with the inaccuracies of the chest one.
