When it comes to watches (and other devices) that are available to help you get fitter (or at least give you some metrics), you have a wide range of options out there. At the simpler end, you have things like my trusty Fitbit One; going to more complex, you have the full-on smart watches that incorporate some form of tracking (some with heart rate measurement as well). While I have previously reviewed one that was a bit short of a true smart watch (the Garmin 920XT, which would give notifications from the phone), we have not looked at many that are purely fitness devices. Well, today we expand that coverage a bit more with the Polar A300.
