Garmin Instinct 2 Runs Forever on Solar

Powered by ultra-efficient solar technology, Garmin’s Instinct 2 is a rugged sport smartwatch that boasts “unlimited battery life” as long as you spend several hours per day out in the sun—with this claim comes some fine print but offers serious activity tracking, GPS, and water resistance to 100-meters. It is available in 40mm & 45mm sizes and a range of colors.
