The Garmin Instinct™ GPS Watch was built to withstand the toughest environments so it can keep up with any and all your adventures. It is made from a fiber-reinforced polymer case that adds durability, while its chemically strengthened, scratch-resistant display is high contrast and sunlight readable. It includes fully vented silicone bands that include 2 independent, removable keeper loops to ensure a secure fit and to keep you from getting caught on things. It is built to the U.S. military standard 810 for thermal, shock and water resistance, and equipped with an internal, rechargeable lithium battery that provides up to 14 days in smartwatch mode, up to 16 hours in GPS mode and up to 40 hours in UltraTrac™ battery saver mode. It can access multiple global navigation satellite systems, including GPS, GLONASS and Galileo, to track in more challenging environments than GPS alone, while allowing you to navigate your next trail with ABC sensors, including an altimeter for elevation data, barometer to monitor weather and three-axis electronic compass, as well as a TracBack® Routing feature that helps you take the same route back to your starting point. Track your vitals, set different activity profiles and connect to your favorite device to get the ultimate experience. Create your own path with the Garmin Instinct™ GPS Watch!
