Great tracker.. previously used jawbone

The Polar M600 is a near-perfect combination of smartwatch and fitness tracker, blending both worlds into a true multi-functional device that is easy on the eyes and easy to use.

The explosion of smartwatches and fitness trackers has thrown up some real gems and thrown down some real turds, leaving us all to step carefully when choosing a new device. Polar is an established name in fitness devices, one of the oldest, perhaps, when dealing with heart rate monitoring.

Solid design; Sports takes priority over smartwatch; All of Android Wear's functions; Polar Flow does so much; Respectable battery performance for a smartwatch; IPX8 waterproofing

Design could be more exciting; Swimming could be better served; Heart rate can be a little erratic; Price

Throughout the past few years, we've had to choose one or the other – fitness trackers or smartwatches . Dedicated fitness trackers might be better at tracking your daily activity and heart rate, but they normally lack things like voice commands and proper notification support – two features...

Accurate activity and GPS tracking IPX8 water resistance Two-day battery life Plenty of third-party fitness apps (thanks to Android Wear

Large; bulky design Display is a tad small compared to the overall footprint Software can be buggy at times Should be ~$100 cheaper

For an Android Wear smartwatch with fitness chops, you can currently do no better than Polar's M600. It offers the most intuitive third-party integration with Google's wrist-based OS we've seen yet, and the comprehensive set of workout options should be exactly what most generalist gym visitors are...

Built-in GPS; Robust fitness tracking; Waterproof

Screen shows scan lines; Not the best-looking smartwatch; Poor battery life on iOS

Polar isn't short of know-how when it comes to sports watches; its M400 GPS Running Watch was one of our all-time favourites. The M600 is altogether a different wrist-based wearable.

Comfortabe to run with; Accurate GPS and HRM; Water-resistant

Silicone strap picks up lint and fluff; Poor-quality display; Charging is slightly fiddly

While we were disappointed with Polar's first attempt at wrist-based tracking with the A360, we found the M600 to be extremely accurate when compared to a chest-strap. We did multiple runs with either a MyZone or Wahoo chest-strap on and the M600 never let us down.

Great Polar Flow integration; Battery life is great; Android Wear fitness apps

Design is bland; Quite pricey (for a Polar; No auto activity detection

If you're in the market for an excellent running watch with a heart rate monitor that also counts steps and has some smartwatch capabilities, the Polar A360 and the Garmin Vivoactive HR are much better options.

High-quality build; Built-in optical heart rate monitor; Runs modified version of Android Wear; Waterproof; Works with both Android and iOS devices

Bulky; Short battery life; Occasionally high heart rate readings in testing; Can't set a custom activity goal

Bought this instead of a Samsung Gear Fit2 Pro, where the GPS barely works ... What a difference ... GPS locks fast, the statistics seem to be fine. Polar's "Flow" app and website provide a good overview of the training. It uses it as a lock-in, and it does it with a goodbye.
