While these two watches look the same, the Garmin fēnix 6 does have a leg up in some important areas. Some people might think that two weeks of battery life in smartwatch mode is more than enough.

This new edition also has a Pulse Ox sensor, which is used for altitude acclimation and sleep monitoring. It determines how well your body is absorbing oxygen.

If you're a runner, you'll love the new PacePro feature, which is designed to help you keep your pacing strategy on track with grade-adjusted guidance as you're running. You can easily create plans right on your watch or via the Garmin Connect app. While you're running the course, you can view your target split pace, the actual split pace, distance to the next split, and how much time you're ahead or behind on your target.
