Style meets strength

When you’re going further than anyone else, you need tools that last with you. Polar Grit passed several military tests, including extreme temperatures, drop and humidity.

At 64 grams, Polar Grit X is one of the lightest outdoor multisport watches out there.

Whether you're out on the trails or preparing for your future adventures with supportive workouts indoors, Polar Grit X comes with all the essential tools you need to make progress and achieve your goals.

Go beyond and back

The ultra-long battery life and multiple power save options make sure Polar Grit X won’t let you down even on your longest adventures.

Learn to refuel

Stay energized throughout your session with the new FuelWise™ fueling assistant. The smart fuelling reminder tells you when it’s time to refuel and helps you maintain adequate energy levels throughout your session, also, gives you an estimation of how many carbs you’ll need to consume during your session, so you’ll know how much fuel you need to bring with you.

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.

With Polar Grit X and Hill Splitter™, you’ll know how you performed on the uphill and downhill sections of your session. You get detailed data about the elevation profile of your training session, and you’ll be able to compare hill stats between different sessions.

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 on Komoot and let the turn-by-turn guidance on the watch keep you on the right track.

When you’re pushing your limits off the beaten track, knowing your way is vital. Polar Grit X helps you stay on the right path and explore new areas safely with real-time route guidance. Plan your route with Komoot and import it to your Polar Grit X for detailed turn-by-turn guidance.

Komoot is a free route planning and navigation app that allows you to easily discover more of the great outdoors. With Komoot, you can create, find and customize routes for all your adventures and navigate smoothly even offline.

Know how well you recover

Recovery from overall stress plays a major role in performance development, optimal daytime functioning, well-being and health. Nightly Recharge tells you how well your body was able to recover from the strain caused by training and other demands of your day. With Nightly Recharge, you know whether your body is ready to go for it or if it’s better to take it easier for a day.

Don’t let the elements hold you back

There’s no such thing as bad weather when you’re well prepared. Polar Grit X shows you current weather and a 2-day forecast.

Discover the ultimate training platform

Polar Grit X goes hand in hand with Polar Flow, the app and web service that keeps all your training, activity and sleep data, plans and progress reports conveniently in one place and at hand whenever you need it.

Smart Calories

Know exactly how many calories you’ve burned based on your weight, height, age, gender, your individual maximum heart rate (HRmax) and how hard you’re training.
