The Polar M430 heart rate watch offers all popular features of heart rate measurement and, in addition, now also an optical sensor for wrist-based heart rate measurement. With its 6 LEDs, it provides reliable measurements and – thanks to the dynamic and intelligent 24/7 heart rate measurement – you can always see how strenuous your day was. Moreover, the training computer, which allows you to create detailed training plans, also features Bluetooth Smart connectivity. In this way, you get smart notifications from your smartphone, connect further external sensors and synchronize your data with the free Polar Flow web service via the Polar Flow app, which is free, too. The extended GPS registers your speed, distance and height and directs you back to the starting point of your training, if necessary, with the Back to Start feature. For indoor activities, which do not allow using GPS, the M430 tracks your speed and distance via the accelerator at the wrist. To top off the features, the watch also offers 24/7 Activity Tracking. This gives you a perfect overview of your daily activity and helps you monitor, for example, the number of your steps and the quality of your sleep.

Thanks to the dynamic measurement process, by taking into account the intensity of your activity and by determining the lowest heart rate, during the day as well as during the night, you get an exact overview of your daily routine. Moreover, activities can be tracked automatically, which cannot be recognized by the accelerator alone, e.g. cycling or pushing a pram. This allows for an even more exact calculation of the calories burnt. The Polar Flow web service and the Polar Flow app give you a complete graphical display of the changes in your heart rate in the course of the day.

• Activity Benefit feature: You can get a feedback anytime via your mobile phone or the web and thus stay motivated
• Sleep Plus judges the amount and the quality of your sleep even more precisely now: It tracks your sleep time automatically when you lie down and your movements become slower.
