Been using chest strap HR monitor watches for almost 15 yeas now (early adopter). Currently I use a Garmin 620 concurrently with my
Watch. The Garmin uses ANT+ radio and can't pair with the
Watch. Was thinking about buying a TICKR (it has ANT+ & BT) to pair with both but would lose a few metrics like Vertical Oscillation, Ground Contact Time and Stride Length (I'm addicted to data). So I decided to keep my Garmin HRM strap and just do with the optical HR on the
Watch whatever it did. On the first run I started (May 25th) my
Watch was reading about 30 to 40bpm too high. On my next run I learned how to correctly wear the
Watch, one notch tighter (snug) and move up my wrist about ½".
Now I have done about 20 runs and 10 cardio machine sessions. My
Watch is always near dead on the same as my Garmin 620 (yesterday's 6.5 miles easy run and Garmin average HR 148 and
Watch 148). I am totally shocked at how dead on accurate the
Watch can be (except in weight training). When worn properly the
Watch is a 1st class HR monitor and can't be beat.
I will continue to wear both and use my Garmin as my primary run/cardio tracker and my
Watch as my over all fitness tracker.
