Who this is for: People who run seriously or compete in triathlons, need physical buttons for use while moving, and want to monitor their performance and progress with richer and more precise data.
Why People like it:In particular, its exceptionally accurate wrist-based heart-rate tracking makes it the only watch we feel confident using for heart-rate-based training without a separate strap. The button-powered interface is easy to use, and it’s more customizable than that of any other watch we tested—you can modify any aspect of the display, from the watch face to the widgets to the activity profiles to the running-data screens.
Its excellent all-day activity tracking, detailed sleep tracking, and nice-to-have smartwatch notifications and apps make it useful enough to wear 24/7. Equally important is that it’s comfortable and attractive enough that we’d actually want to wear it all day.
