What it does
An aluminium smartwatch with an always-on OLED screen, worn on the wrist and paired with an iPhone. Its sensors read heart rate (optical and electrical), blood oxygen and skin temperature, and the watch tracks workouts with built-in GPS; the results appear on the watch and in the iPhone Health and Fitness apps.
