In this blog-post we will have a look at Polar M400 vs Polar M600 Technical specifications & Functional differences to decide if you wish to spend $150 more to buy M600 or save on M400 ?
Polar is pretty old brand in Athletics running watchs … Remember that Polar offered first wireless heart rate monitoring in 1977 !! Ever since it has grown in numbers and technology.
With introduction of Polar M600, Polar claims its first Android Wear device ! as an Activity tracking device as well as a Smartwatch.
Introduction of “Android Wear” in all new M600 obviously gives you powerful features like Google voice activated text messaging ! It also has fine tuning like Silent Alarm over the M400. Needless to say that Polar M600 comes with its own dedicated fitness app, GPS and GLONASS, it’s also waterproof with IPX8 certification (Safe for Swimming) and demonstrates its rugged design with Silicon band.
One more important thing I like for these models is they look great for men & women as well as girls too 🙂 which is very important to share across family and friends 🙂 You can simply exchange his / her sports watch as a change or suit your fashion that day 😛

- M600 features “Android Wear”
Android Wear provides you Google’s smartwatch goodies, but obviously Android Wear can’t be the reason to buy M600 ! Of course, you will enjoy the voice interaction with Google Voice, as well as messages, calls, alerts and contextual notifications popping up onscreen and activity tracking via Google Fit. Also connect with thousands of Android Wear apps too ! - Display

Over Audio Alarm in M400 which can disturb your partner early morning hours, M600 features Silent Alarm - Compatibility with a heart rate sensor
M600 is compatible with Bluetooth® Smart heart rate sensors, like Polar H6 and H7.
Reason you wish to use heart rate sensor could be the type of exercise you do may result into movement in muscles or tendons near the sensor, so better to use separate sensor for accurate measurements of heart rates - Check Android-Wear-compatibility before buying Polar M600
Android Wear is compatible with Android 4.3+ & iOS 8.2+ (iPhone)
I suggest you to visit g.co/wearcheck & check Android-Wear-compatibility of your mobile
Note : Some functions will not be available when your M600 is paired with an iOS, Check list of available functions with yout iPhone here - If you are looking for triathlon watch, then M600 is not suitable, go for Triathlon compatible Polar V800
