Best Traiathlon watches to wear during sports

By | April 2, 2019

The triathlon watch is one of the most important pieces of equipment of an athlete and the selection is a new challenge with every purchase. Which functions should the clock possess? How reliable are the models? And what do you not need as a triathlete?

These are just a few of the questions that triathlon beginners face before buying.

As you can imagine, we have asked these questions countless times in our work with triathlon beginners.

This prompted us to present the best triathlon watches in our opinion. Read how to use the directions in triathlon watch.

In addition, we would like to explain to you in addition what you as a triathlete should pay attention to when buying a watch or what it really matters.

But we also know that some beginners are not willing to spend up to 600 euros for a clock and would first be satisfied with a running clock.


The triathlon watch – that’s what matters!

What counts with a triathlon watch, is actually explained quickly:

The clock should be able to analyze and record all three sports.

So you should be able to record open water swimming (or pool swimming) as well as cycling and running.

On the other hand, the clock should also have the function of making this recording in multisport mode.

This means that the triathlon clock can be set to start recording before the triathlon starts, and then switch to the appropriate mode after each discipline and transition zone.

For the watch that we personally use (the Fenix 3HR) it means that we select the activity “Triathlon”, start the recording and then continue with the round button after swimming.

In this mode, the clock then records the first transition zone.

Have we changed and get on the bike, we press the round button again and turn the clock thus in the bicycle mode.

Of course the same works with T2 and running. Wanna buy the triathlon watches, have a look at top-rated triathlon watches to buy in 2019.

In the end, we stopped every single discipline and analyzed it on the clock.

Better illustrated you will find some graphics in the article about the first middle distance.

There you can also see other data that was recorded (altitude and speed).


The Garmin Forerunner 735xt

The 735xt is an older model that has been on the market for over 2 years.

Nevertheless, in our survey of triathletes, it was – or perhaps for that reason – the most widely used watch.


  • The watch does not weigh 50g
  • She can measure the pulse at the wrist
  • It has not only GPS but also Glonass (the Russian navigation system) and allows a combined use
  • The battery should run for up to 14 hours in full GPS mode and in the more economical UltraTrack mode even up to 24 hours
  • Bluetooth and ANT + connect the watch to other devices


  • The 735xt has only a plastic case
  • The measurement on the wrist is not very reliable, so an additional pulse belt would be necessary
  • The clock is rather large with a diameter of almost 4.5 cm

The Garmin Fenix 3

The Fenix 3 by Garmin is also already a slightly older model, but at that time was considered a milestone among the multisport watches and is still one of the top models.

Meanwhile, there are the Fenix 3 in very different designs.

Worth mentioning here are the Fenix 3HR with a pulse measurement on the wrist * and the Fenix 3 sapphire with an extra reinforced glass *.

Advantages of the Fenix 3:

  • The clock has a comprehensive navigation function
  • Its robust housing makes the watch very resistant
  • It has 32 MB of internal memory
  • The battery runs in UltraTrack mode for up to 50 hours and in training mode for up to 20 hours
  • It not only has GPS, but also Glonass (the Russian navigation system) and allows a combined use
  • In addition to ANT + and Bluetooth, the clock also offers Wi-Fi

Disadvantages of Fenix 3:

  • The clock is quite heavy with 80g
  • The rugged look makes the watch very chunky
  • It is very large with 5.1 cm in diameter
  • Not every model has pulse measurement on the wrist

The Polar Vantage V

The V800 had to make way for precisely this Vantage V, which Polar launched in the fall of 2018.

Together with the Vantage M, the two watches represent the latest big litter from Polar. And since the Vantage V is advertised as a multisport and triathlon watch, it should not be missing here.

Advantages of Vantage V:

  • Pulse measurement on the wrist via 9 LEDs
  • She has not only GPS, but also Glonass
  • Touchscreen (not in sports mode)
  • In sports mode up to 40 hours of battery

Disadvantages of Vantage V:

  • Only Bluetooth and no ANT +
  • Currently still a bad navigation function (will be added later via firmware update)
  • Pretty expensive for a not quite mature watch
