  • Integrated GPS
  • Daily activity goal can be achieved through various activities
  • Very long battery life
  • Training plans for marathon runners
  • Waterproof

With GPS suitable for runners. But only few smart functions.

The M430 running clock of the brand Polar is the only one in our test with its own integrated GPS function.


Rückseite der Polar M430
The Polar M430 is charged via a cable at the rear

The Polar M430 is delivered in a plain package. According to the instructions, it should be possible to set it up using the Polar Flow App. In fact it was not recognized by the app. In the app I was told that I should set up the website on my computer via software. The software is easy to download and install. After following the instructions in the desktop app and setting up the clock, it is also quickly recognized by the smartphone app. The Polar M430 is charged with the special charging cable.

The Polar-Flow-App first needs access to some personal data in order to be used correctly. Before purchasing, everyone should be aware that the transfer of data is unavoidable. Otherwise they cannot be processed and therefore no conclusions can be drawn about fitness.

You can also use the watch without the app. Body height and weight can be adjusted directly on the watch. Of course not all possibilities are available.


The running clock offers many possibilities to get to know.

Steps and distance covered: Tracking the steps works without any problems right away, but when you count them, you will notice that there are considerably fewer steps recorded. Repeated measurements also came to similar results. Manual measurement: 2244 steps/ Polar M430: 2226.

When pushing a flipchart stand, the 50 steps were not recorded. No steps were counted when clearing out the dishwasher.

The measurement of the distance covered is measured with the built-in GPS. When GPS is not available, for example during indoor activities, the M430 measures speed and distance using the accelerometer on the wrist.

Calories burned: The watch measures your burned calories. You can also read them directly in the app.

In addition, the app measures your heart rate and heart rate variability and uses this information to determine your active minutes and fitness level. In addition you can do a fitness test, which failed again and again.

Activity in the PolarFlow App
In the app you can see how your activities are composed

Daily goal: You can set your own daily goal. The clock distinguishes between 3 activity levels or goals. You can reach these by different actions, which are credited to you. For example, to reach the lowest activity level, you need it:

  • 7 hours of low intensity movement (washing up, Tai Chi) or
  • 2:10 hours average intensity (fast walking, circuit training) or
  • 1 hour of high intensity (rope jumping, tennis).

The minutes will be charged afterwards. The clock tells you what percentage of the daily target has been reached. The method of achieving an activity goal is much more sophisticated than most fitness trackers, which only target individual activities.

Training: The watch also supports you in training with different sports profiles. You can load up to 20 profiles onto the watch. Within the profiles, various settings for GPS and heart rate measurement can be regulated. In addition, the planned training sessions can be transferred directly to the Google calendar. You can also create individual training plans, e.g. for marathon preparation. You can enter different distances to be reached. During the training the clock can estimate the estimated target time.

Sleep tracking in the Polar-Flow App
In the Polar-Flow App you can see an overview of your sleep

Sleep phases: The Polar M430 also records your sleep. The sleep analysis is by far not as detailed and reliable as with the other fitness roasters tested. The watch only distinguishes between sleep and wake phases. Tracking is also unreliable and does not record sleep correctly. You can also use a mute alarm clock, which can vibrate you out of your sleep.


After a few days I tried out the whole spectrum of possibilities and got along with the watch in everyday life. The display has no touch function, which is why it is operated using the keys. Clicking through is a bit tedious.

Possibilities on the Polar M430

Many functions can already be set directly on the watch. You can read the time and date on the watch. You can read the number of steps you have taken today and the distance you have covered. In addition, you can read your daily goal and calories burned. In addition, it has a timer, a stopwatch, an interval timer and the target time estimate especially suitable for runners. All personal data such as weight, height etc. can be changed directly on the watch.

Battery: We have tested the battery of the Polar M430. When the GPS is permanently switched on, the watch lasts approx. 8.5 hours. Without the GPS function, the tracker even lasts several weeks. There is also the economy mode. The GPS signal is only located every 60 seconds and lasts significantly longer. The battery level can be read directly on the watch.

The Polar Flow App: The app is relatively easy to use and offers you an overview of your statistics and data, which you can share with friends and acquaintances.


Synchronization with the fitness tracker works well.

The running clock is relatively large and particularly unsuitable for small wrists. The workmanship is of high quality. The bracelet can be changed with some skill. When wearing pullovers with tight sleeves, they are annoying and can hardly be pulled over the watch.

How to play
The instructions are simple and understandable.

We have evaluated about 300 reviews on the Internet. In summary, it can be said that about 65 percent of buyers are satisfied (4 stars) or even very satisfied (5 stars). Partially (2 stars) or completely dissatisfied are about 25 percent of the users. The average score at the time of the evaluation was 3.8 out of 5 stars.
