Solar charging Don't be restricted by battery life. The Garmin Instinct Solar uses the sunlight to boost the battery while you're out doing what you love. It helps to boost the battery life for smartwatch & Expedition modes while you're outside in the sun, so you won't find your battery dying halfway through your trek. Rugged design The Instinct Solar is built to join you almost anywhere. It's water-resistant to 100 m, perfect when you're out on the water, & the silicone band is designed to fit securely, so it won't get caught on things. No matter what you're doing, the military-standard casing is thermal-, shock- & water resistant, so it can keep going as long as you do. The screen has been chemically strengthened to make sure it can stand up to the extremes, & it's scratch resistant too, so it'll stay looking good. The display is easy to read too, even in sunlight that can make screens hard to see. Navigation You'll be able to get around easily with the Instinct Solar. As well as built-in GPS, it's also got a 3-axis compass, barometric altimeter & GLONASS & Galileo navigation systems. What that means for you is accurate tracking, even in the most challenging environments. You can plan your trips in advance on the Garmin Explore website. The Trac Back feature on the watch helps to guide you back the way you came, so you won't get lost on your travels. Health monitoring Stay in perfect shape with all the tracking features. Heart rate, strees, sleep & pulse OX2 can be measured & tracked on your watch, so you can monitor your wellness.
