I just wanted basic fitness tracking (heart rate, active/rest periods, estimated calories burned) that I could use both on traditional workouts like running/walking/biking and swimming. So one platform instead of land-based workouts being tracked and swimming going into a blackhole.

I don't do it competitively, just basic maintenance and general wellbeing.

Finally, it being a watch is a bonus since I will not have to remember to put it on before starting.
