The Polar Vantage M and V are great watches, but they miss some of the functionality of the V800. When paired with Stryd, Stryd will provide pace, distance and cadence info to the watch. The Polar Vantage has autocalibration enabled by default, and autocalibration cannot be disabled. Hence, the pace and distance displayed on the watch are not (necessarily) the same as reported by Stryd. It is also common with autocalibration that the calibration factor continuously changes (to make it more complicated).
