Wearable coach navigation system and health report the Garmin Fenix 7 Pro Sapphire Solar Sport Watch keeps us climbing steady toward our goals. Outfitted with a burly scratch-resistant face that uses the sun's rays to refuel--for 73 hours in GPS mode--and housing that can withstand rugged conditions and submersion this medium-sized watch is equipped to track triple-digit ultras and iron-distance triathlons with ease. If our headlamp fails the built-in LED flashlight keeps the way illuminated and to keep us prepared for nasty weather the barometric trend indicator alerts us to impending storms.
