Garmin - When you can rely on Instinct, the world can rely on you. This rugged, reliable outdoor GPS watch is built to thermal, shock and water resistance (rated to 100 meters). The fiber-reinforced polymer case adds strength and durability, and the chemically strengthened, scratch-resistant display is high-contrast enough to read in bright sunlight, so you can take it with you into the extremes you face every day. Plus, the fully vented silicone bands include 2 independent, removable keeper loops to ensure a secure fit and to keep you from getting caught on things. Multiple global navigation satellite systems (GPS, GLONASS and Galileo) support helps you track in more challenging environments than with GPS alone. Monitor your heart rate all day with Elevate wrist heart rate technology. Take your training to the next level with preloaded activity profiles such as running, biking, swimming and more. Smart notifications at the wrist keep you connected to what matters. Use the TracBack feature to navigate back to your starting point the same way you came. Plan trips in advance using the Garmin Explore app.
