Smartwatches

The Smartwatches category brings together smartwatches and smart rings for anyone who wants to keep track of workouts, sleep and heart rate from the wrist or the finger. You will find models from Garmin, Samsung, Amazfit, Withings, RingConn and Ultrahuman in a range of sizes and finishes.

When choosing a smartwatch, start with the display: AMOLED screens offer vivid colours and good legibility, while the case diameter in millimetres affects how comfortable the watch feels on the wrist. Check for built-in GPS if you want to train without your phone, Wi-Fi and 4G connectivity for calls and notifications on their own, and health-monitoring features. For smart rings, size matters too and should be checked carefully before you buy, along with battery life.
