Garmin Instinct 3 Solar is built for people who take their adventures seriously.
A larger, more efficient solar lens charges the battery continuously in sunlight — delivering unlimited battery life in smartwatch mode when conditions allow, and more than five times the GPS battery life compared to the Instinct 2 Solar in the same conditions.
The metal-reinforced bezel and fiber-reinforced polymer case are tested to MIL-STD 810 standards for thermal and shock resistance, and the watch is water-rated to 100 meters. A built-in flashlight with variable intensities, red light, and strobe mode is standard on every Instinct 3 model.
Health and wellness features cover 24/7 heart rate, HRV status, Pulse Ox, sleep score, stress tracking, and women's health tracking.
Over 40 built-in sports apps include HIIT, running, swimming, cycling, and more, along with Garmin Coach training plans and daily suggested workouts. Available in 45mm and 50mm with fun, limited-edition colorways.

"Works very good. Very durable and accurate with its readings. It fits very comfortably on your wrist and doesn't pinch your skin. I switched from an Apple Watch and it is more lightweight, lasts about a week/week and a half before you have to charge it again, and shows accurate readings!! Highly recommend if you're looking for a new watch and are wanting to track your health."
