Most of the 'fitness' the phone tracks can done far better by a specialized device like the Fitbit, which is outselling the Apple Watch, or just by your phone. The major thing that people buy fitness trackers for... counting steps... can already be done by quite well by your phone since it's the thing that has GPS already (which is what your smartwatch uses) and your phone already has all the sensors to be a pedometer.

If you're the type that doesn't have their phone on you all the time, it's better done by a lightweight, lower-cost Fitbit which start at about 60 bucks as opposed to the $350/$400 starting point of the Apple Watch.
