The draw: HR without the strap

If you like to train using heart rate zones to dose your workout effort and gauge fitness, this is the watch you’ll want on your wrist. No need to bother with a chest strap: An optical sensor on the back of the watch face detects heart rate and displays it continuously in large, easy-to- read numbers. Our tester liked the watch’s sleek profile, and found the heart rate reading to be generally accurate, barring a couple of random jumps when the watch jostled around slightly. The fairly basic capabilities (heart rate, time) can be extended using apps like Strava and MapMyRun.
