Show Description

Optimized for running, the M430 teams up with your phone for a personalized training experience. Equipped with Polar’s 6-LED optical heartrate monitor, you get information straight off your wrist, no need for a finicky chest strap. Internal GPS provides speed and distance info, while an accelerometer adds pace to the equation. Polar’s Running Index helps you run smarter, not harder. After each run, you get a score to help improve your running efficiency. The free Flow app lets you customize up to 20 different activity profiles, set heartrate zones, and adjust your watch’s settings from your phone. Get instant digital bragging rights with smooth fitness app integration: when you finish your workout, stats are directly uploaded. 24/7 activity tracking keeps an eye on your day to day movements. Smart notifications keep you connected, giving you a subtle vibratory nudge when the digital world needs your attention. And the Sleep Plus mode helps you keep track of your sleeping patterns, a better sleep, means a faster recovery.
