While the Grit X2 Pro is aimed at serious outdoor athletes and extreme performance, the Street X is a more accessible all-round smartwatch designed for everyday use and hybrid athletes. In this comparison, we look at the display, materials, battery life, features, sensors and ultimately: which one you should choose.
