The Garmin Fenix 6 Pro does everything you need it to—and then it does some more.
With its 47mm diameter, the Fenix 6 Pro sits in the middle of the new Fenix lineup: The Garmin Fenix 6S Pro has the smallest 42 mm-diameter size, while the Garmin Fenix 6X Pro bumps up to a 51mm diameter.
Garmin cut the lens from durable Corning Gorilla Glass and encased it in a rugged stainless steel bezel or steel bezel coated in Diamond-Like Carbon. Packed inside the fiber-reinforced polymer case is a 1.3” color display and powerful battery. In its most efficient mode, Garmin says the Fenix 6 can get up to 48 days on a single charge.
Garmin Fenix 6 Pro battery life:
In real-world use, the battery lives up to Garmin's claim. In the Fleet Feet Garmin Fenix 6 review, a tester says he got nearly three full weeks of regular training and use out of a single charge without changing any of the watch's settings.
An interchangeable strap ties the watch to your wrist and lets you swap it in and out without any tools. Garmin also made the Fenix 6 watertight: It has a water rating of 10 ATM, which means it can withstand water pressures equivalent to 100 meters.
Designers gave it a wrist-based heart rate monitor that lets you track your ticker so you can train in different effort zones, and there’s a Pulse Ox sensor that helps dial in altitude acclimation and improves sleep monitoring.
Like other Garmin running watches, the Fenix 6 comes with GPS, GLONASS and Galileo tracking, and it gives you turn-by-turn navigation for when you’re running somewhere new.
Complete with safety and incident detection features that can send your location to a list of emergency contacts, the Garmin Fenix 6 Pro has you covered from warmup to cool down.
