Running is where this Huawei WATCH GT Runner 2 does its best work. It's a sports watch that tracks your training in detail, from route and distance to pace, using built-in GPS that picks up satellite signals on your wrist rather than leaning on your phone. The 1.32-inch AMOLED screen stays clear and bright when you glance down mid-stride, and the touchscreen makes scrolling through your stats quick with a flick of your thumb. Wrist sensors keep an eye on your heart rate, blood oxygen, sleep quality and stress levels, so you get a full picture of how your body is coping with training. There are workout modes for indoor and outdoor sessions too, plus personalised training guidance to help you improve. It pairs with Android and iOS phones.
