Review Polar M430 GPS (Part 1): Support Many Features

It has been a few months since Polar announced the M430, which is based on the prevalent previous Polar M400 GPS model, which is aimed at the jogging community. The Polar M430 is an upgraded, most advanced running watch since the M400, offering features that help it keep pace with the market – especially the optical heart rate sensor.

But it doesn’t stop there. Polar M430 has added vibration as well as a battery-saving GPS mode, which helps the watch run longer, plus some minor changes that Techwear will analyze further in this article.

First, we’ll start with what’s in the box. Polar M430 will have three colors all: white, black, and orange. Inside the box, you’ll find three things: the watch, the charger, and the manual.

The charger cord is a new accessory for Polar M430, replacing the Micro-USB head in the Polar M400 model. The Micro-USB charging cord/port first, though meeting all standards, is a nightmare for Polar whenever the Polar M400 model is confronted with water, causing the company to support customers continually.

The problem with standard micro-USB port design is that they are not very good waterproof because they are often worn out in small parts. Anyway, if the charger design is waterproof, they will last longer. So here is a picture of the new charging port.

The other end is a regular USB connector that can be plugged into any USB port. The charger cord can help you charge and sync if you use your computer to sync instead of your phone.

Next, you have a small catalog showing where the watch is worn and how to use it. Most notes are on paper, as you should not wear a watch on the wrist bone. If you find this review confusing, look at the illustrations available.

On the back, you’ll find an optical heart rate sensor.

On the front, you have a screen surrounded by a black border. Both sides have buttons, three on the right and two on the left.

With that in mind, analyze how it works.

Basic Features

As noted before, there are a lot of changes in the Polar M430 compared to the Polar M400, so we better analyze these two first to ensure everyone understands each other. We will start with the following list:

  1. Add an optical heart rate sensor
  2. Add vibration function (warning)
  3. Increase battery life a bit more
  4. Add a new battery-saving GPS model: Allow the device to operate for up to 30 hours in GPS enabled state

High accuracy mode:

  • One-second recording mode: GPS location determination every second, heart rate is also recorded in seconds
  • Average accuracy recording mode: Identify GPS every 30 seconds, heart rate records every second
  • Battery saving mode: Defines GPS every 60 seconds, the heart rate recorded every second.

Also, Polar has some minor changes in features as well as design.

  • Change the wristband design
  • Add new watch faces
  • Allow fitness test with optical heart rate sensor
  • Add a new sleep tracking algorithm
  • Allows software updates via Bluetooth
  • Add timer function
  • New connection cord
  • 24×7 heart rate monitor feature

With the new features listed, start with the first one – the main screen is noticeable. With it, the Polar M430 watch face displays not only the time but also the current state of your activity for the day (calculating the remaining until the target step is reached).

The screen may change, as mentioned in the previous section, Polar M430 has some new watch faces.

Next, you will press the button below to enter the summary of ‘My Day,’ giving you an overview of the progress of your day. Moreover, you can also press the enter/red button to see any assignments that have been completed during the day. It is like a time chart of your day in terms of activities.

Keep pressing down. You will see ‘Diary,’ which shows the daily activities in the previous period and the total training index.

After Diary is the Settings section, which allows you to change some aspects of the sports records you have configured on the watch (other elements can be configured via the network), as well as settings. Body indicators (such as height/weight), then the watch specific settings (like pairing with your phone/sensor, notification options, and device preferences) were.

Finally, you’ll get to the Fitness Test, Timer and Favorites section, and other exercise functions, but we will mention all those sections in the next chapter. Application in sports activities.

Before we get to that, let’s talk about how the watch keeps track of your activities on the app. Of course, we have shown you how to count the total number of steps on the side of the watch, but let’s look at how it displays on the app. Below is a picture of the main activity tracking page

It shows your day-to-day overview, complete with activity levels. You will see all the exercises listed on a small red dot. Scroll down, and you will see the inactive stamp and summary information.

The sign does not work when you are lazy, and the device must give a verbal warning. In fact, with the M430, it is a vibration alert that forces you to operate. It’s similar to what Fitbit, Garmin, and other GPS running watches remind you to work with, though not as often as those brands. With Fitbit and Garmin, it’s easy to predict when the device will alert you, but with Polar, I rarely get marked inactive. Not sure why.

In addition to the daily index, you can have weekly and monthly indicators as well.

Note that Polar M430 doesn’t count the number of steps, mainly because it doesn’t have a barometer or altimeter, which is needed to calculate the steps.

However, it has a sleep tracking feature. You will see the sleep indicators on the application.

Further research on the app (currently only available on iOS or Android), you can customize the profile of the sport from the app. This includes things like changing fields and data ranges. Currently, it’s pretty detailed. You can change almost anything (if not all) on the phone app.

The phone app has options for connecting to three different platforms, including Nike +, Strava, TrainingPeaks, MyFitnessPal, and Apple Health. Some of these can be configured via the Polar Flow website.

This means that after completing the exercise, the data will automatically be uploaded to platforms like Strava. It works quite well and is handy if you take advantage of it. Finally, push notifications from smartphones. The Polar M430 will display phone notifications from any app with notifications (for both Android and iOS).


On the outside, the Polar M430 was no different from the M400 a few years ago. They provide an optical heart rate sensor as well as excellent GPS results. Not to mention the small and small improvements that many people want, such as vibration alerts, longer battery life with many choices of modes to help save battery, monitor sleep.
