    Sounds like the watch is losing contact with your wrist. It needs to be in contact to measure the HR. I saw that a couple of times on my workouts, now use a wrist band to keep the watch a bit up my arm to make better contact. Seems to work better.

    I have found that no matter how tight or loose and no matter how high or low on the wrist, there are times my AW does not maintain a HR reading sometimes. I have owned three AWs and all were the same.

    Tightening mine to where it doesn't move at all solved this for me but I only glance at it about ever 1/4 mile so it could do it and me not catch it. It was pretty bad before I figured out that it needed to be tight.

    I had to get a heart rate monitor (polar H7 chest strap). My AW did the same thing.

    Slightly high on the wrist and flipped around so it's on the inner part of your forearm (the side your palm faces) is the most accurate way to measure your HR, or so I've read.

    I have tried that multiple times and so have my friends and the AW still fails at times.
