The Outdoor Watch Polar Grit X is an uncompromising combination of rugged and durable, yet lightweight design and top training features that make sure you’re ready for your future adventures. It comes with built-in GPS, a barometer, 2-day weather forecast and unique features such as FuelWise that helps you maintain adequate energy levels during your long sessions or Hill Splitter that provides detailed data about your performance on the uphill and downhill sections of your session. The FitSpark training guide make sure you’re prepared for your pursuit to conquer the trails with ready-made daily workouts that match your recovery, readiness and training history. 

You might also appreciate the popular Komoot app that allows you to plan your route, import it to your Polar Grit X and let the turn-by-turn guidance take care of navigation for you. The Polar Flow app allows you to plan all your training from individual workouts to full season plans, supports all kinds of sports and is compatible with most iOS and Android devices.

Designed for outdoor use, this watch features a glass fiber reinforced polymer back cover, a silicone strap and an extreme high strength stainless steel case. What’s more, the watch is so light that you won’t even feel it on your wrist. Laminated Gorilla glass lens with anti-fingerprint coating is the icing on the cake.

Learn to refuel

Stay energized throughout your session with the new FuelWise fueling assistant. FuelWise automatically calculates how much carbs you need for your session. It monitors your energy expenditure during the session and adjusts the automatic fueling reminders to match your carbs consumption so that you’ll feel energized all the way to finish. You can also set yourself a drink reminder at your chosen intervals, and FuelWise makes sure you remember to hydrate regularly.

Elevate your goals

The detailed uphill and downhill stats from Hill Splitter tell you how you performed on the ascent and descent sections of your route. Hill Splitter automatically detects all uphills and downhills by using your speed, distance and altitude data. It shows you detailed insights into your performance, such as heart rate, distance, speed, ascent and descent, for every detected hill on your route.

Stay on the right path

Plan your route with Komoot and import it to your Polar Grit X for detailed turn-by-turn guidance. The Polar Grit X helps you stay on the right path and explore new areas safely with real-time route guidance.

Don't let the elements hold you back

There’s no such thing as bad weather when you’re well prepared. The Polar Grit X shows you current weather and a 2-day forecast. It provides information about wind speed and directionair humidity and precipitation. The watch is also water resistant (100 m).
