Polar M400 Pink GPS Running Watch with Heart Rate

Model #90057191

The Polar M400 has good battery life, can sync wirelessly with your phone, includes GPS and activity tracking, charges through a normal Micro-USB and supports wireless heart-rate monitors. It also has automatic sleep tracking, an always-on display with a backlight, inactivity alerts and is waterproof.

Polar M400 is feature-packed and waterproof. Polar M400 offers a good set of features for beginners and advanced runners a like. It also provides feedback on your daily activities and sleep.

Polar M400 is an exceptional blend of sporty design, integrated GPS and advanced training features, along with plenty of options to keep an eye on your activity 24/7. The M400 gives runners the freedom to explore new, more adventurous routes: you can measure your pace, distance and altitude and find your way back home.

Polar's latest watch looks to further bridge the gap between activity trackers and GPS running watches.The Polar M400 is the company's second GPS watch that includes tracking for things like steps taken, distance traveled, calories burned and sleep.The Polar M400 is slimmer than other running watches, but not nearly as discrete as say the Microsoft Band. It utilizes a rubber watch strap with a security loop to sit snug on your wrist. The strap is quite soft, which makes the watch comfortable to wear, despite being so large. Don't get me wrong, though, you can still feel it on your wrist. It's not like other activity trackers, such as those from Fitbit or Jawbone, that are small and lightweight, although as far as running watches go, it's relatively comfortable.Polar M400 Pink GPS Running Watch with Heart Rate

Here’s the low-down of the M400.The M400 is Polars second GPS watch that integrates activity tracking, following the much more expensive V800 multisport watch. The M400 is designed as a runner’s watch, but blends in support for other activities such as cycling and…horse back riding. Given that it’s a runner’s watch however, it doesn’t support cycling sensors, nor horse gait pods. 
With the internal accelerometer the unit will track steps, distance, and sleep (along with calories), throughout your day. 

It doesn’t however use the internal accelerometer to give you cadence while running nor pace/distance on a treadmill – you’ll need a footpod for both of those.The battery life gets about 8-hours in GPS-on mode, like most watches in the category, and gets about three weeks in regular day to day watch time/activity tracker mode.Like most Polar watches the M400 includes a number of ‘Smart Coaching’ features.  However, one unique feature being introduced with the M400 is the Running Estimator option, which estimates how long it’ll take you to complete your run of a set distance at the current pace you’re running – thus taking the complex mid-marathon mental math out of the equation. 

They’ve also added in PR support (Personal Records/Bests), which will tell you each time you break a new PR for a given distance/time/watermark.Lastly, the unit is well waterproofed at 30-meters, despite using just a standard micro-USB connector.  Though, while it is waterproofed, it won’t give you heart rate underwater, as it only supports Bluetooth Smart heart rate transmission and not the analog frequency used on some of Polar’s other water-friendly watches.
