Question for all the Apple Watch owners out there. Do you find your watch to be accurately tracking distances and HR? I have a series 2 aluminum and have been calibrating it on every walk and several 5 mile runs over the past two weeks. However, when running (at the same pace, and same distance) that I did outside on the treadmill, I get distances that are under reported by more than 25%. A 5 mile run on the treadmill as an example is giving me 3.75 - 4 miles max in the workouts app. As for HR, I do think that the sensor is generally providing a good reading as it ties to what my past Fitbit Charge HR and the HR monitor on the treadmill say at any given time. However, what I notice for every workout is that I will get periods of time where it is either not reading my pulse OR at the peak of my run when I know my HR is 170+ it drops to 130-140 for a few minutes and then back up... all while my pace has been constant. For reference, the Fitbit retains the 170+ reading the whole time. Note that the band on the apple watch has been made tight and is worn above the wrist bone... and does not move during these occurrences. Interested to hear others experiences. Thanks.
