Best GPS running watch of 2017?

Reliable running metrics is only a part of the Polar M430 experience.

What truly sets Polar M430 apart is its ability to help you turn running data into insight and action. Paired with Polar Flow, the Polar M430 turns into a reliable running coach that provides personalized feedback, an adaptive training plan, and live guidance for athletes during different stages of their training sessions.

The Polar Running Program considers your training history, gauges your current activity levels, accounts for a final goal date and target distance (5K, 10K, half and full marathon) and then builds a personal running program in seconds. Polar Running Program also isn’t your run-of-the-mill spreadsheet running plan. You can upload your training plans to the Polar M430 and let it guide you during your sessions.

Watch the video below to get a feel for what the Polar Running Program is like:


Other advanced Polar Smart Coaching features include Running Index, which uses data to show the efficiency of your running, Fitness Test, which enables athletes to gauge their current fitness levels and see progress along the way, and Training Benefit, which provides feedback immediately after a training session to explain the benefits of a workout.

What’s new with the design

The design is fully waterproof and features a lightweight, breathable wristband and vibration alerts. Polar M430 comes in dark grey, dark blue, white orange and neon green. Polar M430 features the same 5-button design as Polar M400, suited for easy handling in difficult conditions.

The black-and-white screen is easy to read even – or should we say especially – in direct sunlight. We’ve also added in new watch faces.

Accurate optical heart rate tracking with Polar M430

Optical heart rate monitoring on the Polar M430

Polar M430 has our proprietary wrist-based heart rate technology with 6 LEDs. This mean that inside the watch, there is the technology that detects (which includes the LEDs) the pulse waves. There’s also the heart rate algorithm that interprets the raw data it’s getting.

Compared to other Polar products the Polar M430 is also different in form factor, size, weight and how it sits on the wrist.

All these three (tech, algorithm and the form factor) form the heart rate solution, and we can tweak each one of them to get optimal results. For Polar M430 we have noticed that the 6-LED solution gives us (and you) the best results.

With the Polar M430, you can for the first time do the Polar Fitness Test with wrist-based heart rate. We feel that this speaks volumes of the accuracy and reliability of the heart rate tracking on Polar M430.
