Technologies:
ACCURACY FIRST: Developed by Polar, the Precision Prime™ sensor data fusion technology measures your heart rate from your wrist. This innovation uses an optical heart rate measurement technique in combination with other types of sensors to eliminate any movement artefacts that might interfere with the heart rate signal and distort the results.
KOMOOT GUIDE: Plan detailed routes and create a map using komoot, then sync them with your Watch to enjoy accurate route guidance throughout your journey.
GLOBAL SATELLITE NAVIGATION SYSTEM: Work out whilst enjoying the best geolocation solution, wherever you are in the World.
The integrated GPS works with the international satellite navigation systems Glonass (GPS) and Galileo, as well as with the regional satellite navigation system QZSS, which covers East Asia and Oceania. This means you have access to data on speed, distance and route that is precise, wherever you are in the world.
TRAINING LOAD Pro: After each session, Training Load Pro shows you the level of strain your workout places on your cardiovascular and musculoskeletal systems (cardiac load and muscular load). Perceived exertion allows you to assess how tired you feel and to immediately gauge the level of exertion your body is undergoing. This allows you to track your training load over the long term.
WRIST DRIVE POWER FOR RACE: Polar Running Power is measured at the wrist. It is unique in that it provides accurate, scientifically validated data, enabling extremely high levels of precision to be achieved continuously, without the need for additional sensors. All you need to do is use your watch.
FUELWISE: FuelWise™ is a personalised nutrition guide that helps you optimize your nutrition during long training sessions and sporting events.
HILL SPLITTER: The Hill Splitter™ feature automatically detects uphill and descent sections based on your speed (calculated using GPS), the distance travelled and barometric altitude data.
SLEEP PLUS WORKSHOPS: The Sleep Plus Stages™ feature is automatic and tracks the duration and quality of your sleep. It also shows the time spent in each phase during the night. Tracking your sleep helps you identify factors during the day that may have a negative impact on your sleep. It also allows you to analyse your sleep patterns over the long term.
SERENE: Serene™ guides you and helps you breathe at a slow, steady pace to synchronise your heart rate with your breathing rhythm – six breaths per minute, which is the optimal breathing rate for relieving stress.
PERFORMANCE TESTS: The Running Performance Test allows you to track your progress and customise your power, speed and heart rate zones.
The Cycling Performance Test helps you track your progress, allows you to customise your power zones and identifies your personal functional power threshold. A compatible power meter is required.
RECOVERY TEST: The Leg Muscle Recovery Test indicates whether your legs are ready for a high-intensity workout. It only takes two minutes and doesn't require any special equipment.
The Orthostatic Test is a reliable and simple way to assess your recovery following intense and frequent workouts, as well as to optimize your training by avoiding overtraining.
The Recovery Pro™ feature uses data from Training Load Pro™, the results of the Orthostatic Test and how you feel to show you your recovery status.
MUSICAL COMMAND: Browse your playlist and adjust the volume directly from your Watch. Your Polar watch connects to the music applications on your phone. This means it is easy to control your music without having to take your phone out.
WEATHER REPORTS: Check the weather at your current location and view hourly forecasts for the next two days, including details such as wind speed and direction, humidity and temperature.
