Not many companies try to do what Garmin does with the Fenix line of fitness watches. While Apple and Google have their own general-purpose smartwatches priced around $300 (neither of which comes close to the Fenix's tracking abilities), Garmin and a handful of other companies make super-expensive fitness watches that are meant for the most active among us.
The new $599 Fenix 5S is one of the models in the new Fenix 5 line that promises premium design and style. It also has the most advanced tracking abilities—with onboard GPS, GLONASS, barometer, altimeter, heart rate monitor, and other sensors—and it delivers a full smartwatch experience with Garmin's own UI, widgets, notifications, and app store. No matter how you look at it, $600 is a lot to spend on a fitness tracker. But if money is no object and you need the most capable tracker you can get, the 5S may be for you.
