When you can rely on Instinct™, the world can rely on you. This rugged Garmin GPS watch is built to MIL-STD-810G and is water-rated to 100 metres. Keep your bearings with a built-in 3-axis compass and barometric altimeter. Multiple Global Navigation Satellite Systems (GPS, GLONASS and Galileo) help 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™ website and app.
