It is generally recognized that the Fitness Surge is a fitness tracker that doubles as a running watch with its built-in GPS and wrist-based heart-rate monitor (HRM).
It has a squarish 1.25-inch touchscreen display that is surrounded by a thick bezel. There are two buttons to the right of the display, and one on the left.
The time is always displayed. You can choose to display any of the four watch face options from the Fitbit app.
Frankly speaking, the Garmin Vivoactive HR ($249.99) is an upgraded version of the Garmin Vivoactive£144.95 at Amazon, one of our favorite fitness trackers. As you might be able to tell from the name, the biggest new feature is a continuous heart rate monitor. Or, it retains many of the same features as its predecessor, including built-in GPS to record outdoor runs, sleep tracking, on-screen weather reports, and vibrating push notifications from your smartphone.
As easy to live with as a Pebble, as slick as an Apple Watch and with a tactile, rotating bezel as its secret weapon, the S2 is the kind of smartwatch you'd kick yourself for leaving at home. You'll have to pay extra for the cellular version to make the most of the GPS features but even the standard version feels like a leap forward.
