The app is constantly giving feedback on your health, sending tips and insights as notifications to your smartphone.

What is a fitness watch and what can it do?

Smartwatch, fitness watch, fitness tracker - aren't they one and the same? 🤔

Not quite, although all these devices support you during training, the focus of the wearables is different.

That's why we'd like to take a closer look at what features make up a fitness watch.

A fitness watch is a smartwatch that offers you a wider range of training functions.

The devices support you with various pre-installed workouts and training plans. 💪

You can see the sports functions on the fitness watch.
Garmin Fenix 7

Fitness watches track a variety of different data relevant to your training.

These wearables also feature a large display, which allows you to read the most important information right from your watch.

You can also get even deeper insights in the corresponding app. 📱

You can see the recorded pulse on the fitness watch.

Settings can be individually adapted to your personal needs and can be adjusted directly via the gadgets.

Meaning you can leave your smartphone at home. 🥳

Comprehensive evaluation of your training data allows you to improve your athletic performance as quickly and effectively as possible. 🥳

Basic smart functions

In addition, the wearables also complement your smartphone by offering you basic smart functions.

For example, incoming calls and notifications are displayed directly on the best fitness watches. 📞

They often feature an integrated music player so that you can also listen to music offline. 🎶

You can see the music function on the fitness watch.
Garmin Fenix 7

Especially handy: If your wearable features offline music storage, you can leave your mobile phone at home during exercise and still listen to music. 🙌

Many fitness watches often come equipped with an integrated NFC-chip so that you can easily make contactless payments with your watch. 💶

Overall, smart functions on fitness watches are much more limited than those of conventional smartwatches.

The focus of a smartwatch is on optimally complementing your mobile phone and fitness tracking at the same time. A fitness watch, on the other hand, is primarily intended for sports.

What is the difference between a fitness watch and a fitness tracker?

To find out the difference between a fitness watch and a fitness tracker, let's first take a look at what exactly a fitness tracker is. 👇

What features do the best fitness trackers have?

As the name suggests, a fitness tracker also supports your training.

Just like fitness watches, the devices record a wide range of fitness and health data and then make it available to you in the corresponding app. 📱

Some fitness trackers also offer training programmes.

Recorded data from a fitness tracker is visible on the mobile phone.
Ⓒ Fitbit

Although fitness trackers offer you good support during your training, they have no or very few smart functions.

Fitness trackers often do not have a built-in GPS. Instead, they use the GPS of your smartphone.

Of course, this also means that you need your mobile phone with you at all times during training. 😕

Comparing fitness watches and fitness trackers

Now we know what generally distinguishes a fitness watch from a fitness tracker.

One important difference between these wearables is the display. Fitness watches usually have larger screens that can display more data at once.

In addition, fitness watches also offer a wider range of analysis tools and thus provide the best support for your training.

For the most ambitious athletes who want to improve their performance as efficiently as possible, a fitness watch is the only option.

A fitness tracker, on the other hand, is the right choice for beginners. 🥳

These devices allow you to record your fitness and health data throughout the day. However, you will miss out on extensive analysis tools and smart features.

What are pulse watches and running watches?

Besides smartwatches, fitness watches and fitness trackers, there are also pulse watches and running watches.

Running watches almost exclusively offer functions for runners. 🏃

Running watches are a good choice for professional runners who are just looking for support for their training. Here, you can find everything about the best running watches in the UK.

Pulse watches, or heart rate monitor watches, are primarily designed to measure your pulse and heart rate during exercise.

These wearables existed long before smartwatches appeared on the market.

Info: You can also use a chest strap to accurately record your pulse during training.

Are fitness watches worth buying?

The best fitness watches in our reviews come with all kinds of different features.

But what exactly makes each wearable worth purchasing? 🧐

And what issues might dissuade you from purchasing a particular fitness watch?

Let’s take a look at this together below. 👇

The perfect companion for your workout

As we have already mentioned, fitness watches offer particularly comprehensive support for your training.

The best fitness watches make your training sessions far more professional so you can get the most out of your workouts. 🚀
You can see the recorded training data on the fitness watch.
Garmin Fenix 7

By viewing your recorded data, you can find out exactly where your strengths and weaknesses lie.

Move more throughout the day

Fitness watches track your fitness and health data not only during sports, but also in your day-to-day activities.

Among others, fitness watches use the following metrics:

  • Pedometer (step counter)
  • Floors climbed
  • Distance travelled
  • Calorie consumed
You can set individual goals for each day.
You can see the activity tracker on the Huawei Watch GT 3.
Huawei Watch GT 3

As soon as you have reached your step goal, for example, the smart wearable notifies you.

A pedometer like this naturally encourages more movement in everyday life, which contributes to a healthier lifestyle overall. 🙌

Disadvantages of a fitness watch

As with everything, there are of course two sides to the coin when it comes to fitness watches.

Let’s go into the disadvantages in a little more detail below. 👇

Partially inaccurate measurement data

Depending on the device, fitness watches may not provide 100% accurate measurement results.

Info: High-end Garmin wearables track your pulse most accurately.

Alternatively, to record particularly accurate measurements, you can purchase an additional chest strap.

Polar H10*

Garmin HRM Pro*

Due to their design, smartwatches, fitness watches and fitness trackers also have difficulty tracking your routes accurately.

You can see the map function on the Garmin Fenix 6 Pro.
Garmin Fenix 6 Pro

This is because the GPS data can be distorted due to the way it is worn and arm movements.

However, these GPS inaccuracies are minimal among the best fitness watches we have reviewed.

Results not medically validated

The best fitness watches we have reviewed can measure a variety of health data, such as blood oxygen levels. In some cases, they can even create an ECG.

That being said, even the best wearables are not capable of delivering medically validated results.

The recorded data can still provide helpful indications towards possible illnesses.

Shortcomings in data protection

Fitness trackers and watches collect a lot of sensitive health data throughout the course of your day.

But what exactly happens with this data? 🤔

No one but the manufacturer can answer this question.

It is advisable to limit the amount of data you share via your smart device.

Which fitness watch should you buy? - Function review

With so many different wearables to choose from, it's hard to know which fitness watch is right for you.

The best wearables from our review offer optimal support for your workout. 🏃

But the range of functions available in individual wearables naturally differs somewhat. Not all models have the same features.

It is therefore essential to figure out which functions are most important to you when shopping for a fitness watch.

Let’s take a closer look at the various functions together. 👇

Pulse and heart rate tracking

There are actually very few wearables available today that cannot measure your heart rate and pulse.

Info: Heart rate and pulse are among the most important pieces of information for endurance training. They provide information about the current strain on your cardiovascular system.

This gives you an insight into your current fitness level. 🙌

What is the difference between heart rate and pulse?

Every time your heart contracts, blood is pumped through your body. The detectable beat in your arteries is known as your pulse.

However, some heartbeats may be so weak that no pressure wave is perceived in the arteries. This is known as an "absent pulse."

These missing heartbeats are not counted in your pulse. They are only recorded by heart rate. A doctor should be consulted if there is an accumulation of missing heartbeats.

Optical sensors are located on the back of fitness watches to measure pulse and heart rate.

You can see the sensors on the Huawei Watch GT 3.
Huawei Watch GT 3

The best fitness watches we have reviewed feature heart rate sensors in the wearable itself. 🚀

Cheaper models usually do not.

Measuring pace and distance

Accessing information about the distance and speed of routes travelled (or even sections of routes) is an important factor, especially for runners and cyclists.

This data is measured using GPS tracking and accelerometer sensors.

This information can help you optimise your training and cover distances in even less time in the future. 🙌
The Garmin Fenix 7.
Garmin Fenix 7

Measuring your VO2max

VO2max is an indicator of endurance capacity.

The VO2max rate indicates how many millilitres of oxygen your body can utilise per minute and per kilogram of body weight under maximum exertion.

This information is particularly important for runners, so you may want to look out for this feature when shopping for wearables if you are serious about running.

The Garmin Fenix 7.
Garmin Fenix 7
Please note: In order to determine pulse zones and fitness levels as accurately as possible, you should ideally be able to enter your maximum heart rate manually on your smart watch.

How is maximum heart rate (HRmax) calculated?

The maximum heart rate (HRmax) is mainly dependent on age, training condition and gender. Therefore, the value naturally differs from person to person.

The most common formula for calculation is the following:

  • When running: HRmax = 220 - Age
  • When cycling: HRmax = 200 - age

However, this formula is quite inaccurate and does not take into account the difference between sexes. Women usually have a somewhat lower HRmax. The following method provides more accurate results:

  • Women: HRmax = 206 - (age x 0.88)
  • Men: HRmax = 207 - (age x 0.7)

The fitness watches in our review allow personalised HRmax entry. 🥳

Smartwatches, such as those from Apple or Samsung, often do not offer this option.

Movement analysis in the best fitness watches

The best fitness watches in our comparison also analyse your movement.

They not only feature a pedometer but also measure step frequency and register vertical movement, for example.

Smart wearables can recognise and analyse your movement patterns.

You will then receive tips on how to improve your running or cycling style and make it more gentle and effective. 🙌

Recovery advice: When is it time for a break?

Ambitious athletes know that their own performance can only improve during rest periods.

So if you want to improve, sufficient recovery phases are essential. ☝️

Training too hard coupled with too few recovery days will harm your body instead of helping it.

The best fitness watches in our comparison evaluate your training and inform you when it's time for a recovery phase.

Fitness watches for swimmers, skiers and golfers

Some fitness watches offer special features for swimmers, skiers and golfers. 🏌️

Of course, the best wearables are also waterproof.

Looking for a smartwatch optimised for your swim training? We've reviewed the best swimming watches here.

Attention: If you want to use your watch for your swimming, it should feature integrated GPS, as you will not have your mobile phone with you in the water. ⚠️

Navigation equipment for outdoor enthusiasts

The best fitness watches also have something in store for hikers, mountaineers and outdoor enthusiasts. 🏔

Thanks to pre-installed map material or navigation services, smart wearables can also be used as navigation systems.

An integrated compass and barometric altimeter are also usually included. 🧭

Additional apps, such as Komoot or Strava, offer you even more map material. 🗺

However, not all fitness watches allow these apps to be installed.

Sleep monitoring: how restful your night was

The best smartwatches can also monitor your sleep. 🥳

The recorded data is then made available to you in the corresponding app.

Here you will find, among other things, the following information:

  • Time taken to fall asleep
  • Duration of sleep
  • Sleep phases (REM, deep, light sleep)
  • Waking phases
  • Sleep score (gives information about the quality of your sleep)

If you're looking for a great wearable to track your sleep, check out our review of the Oura Ring and of the Circular Ring. 😴

Extensive support thanks to a variety of training plans

Of course, the best fitness watches not only record all data during your workout, but also support you with a variety of pre-installed training plans. 🙌

You can also create completely individual training plans and tailor them exactly to your personal needs.

With some wearables, you can even plan entire training weeks. 🤩
Garmin Connect App.

Extensive analysis tools and training evaluation in the app

In the companion app, you can not only create your training plans but also evaluate and analyse your workouts.

Fitness watches from Garmin and Polar in particular offer highly detailed analyses of your data.

This way you can always get the most out of your training and improve your performance as effectively as possible.

Automatic activity detection

The best fitness watches in our review can automatically recognise and record activities.

This way you'll never forget to track your workouts again! 🙌

Some sports watches even have multisport-modes for triathletes and special features for preparing for competitions.

Overview of smart functions on fitness watches

The best fitness watches not only support you during your workout but also feature some smart functions.

For example, displaying incoming messages and calls directly on your wearable.

You see an incoming call on the Fitness Watch.
Huawei Watch GT 3

Many fitness watches also offer you the option of answering messages or taking calls directly via the wearable.

However, the response functions on sports watches are quite limited in contrast to conventional smartwatches.

Note: When it comes to iOS devices, the response function is limited to Apple watches. ⚠️
You can see an incoming call on the Huawei Watch GT 3.

Some fitness watches also offer the option of storing music on the wearable and listening to it offline. This way, your mobile phone can stay at home while you exercise. 🎶

Without this feature, you must be in close range of your smartphone with Bluetooth switched on in order to stream your music from apps like Spotify.

Some manufacturers also offer LTE versions of their watches, which allow you to access your mobile network and receive messages independently of your smartphone.

Devices with an integrated NFC -chip even allow you to make contactless payments at the checkout. 💶

You can see the reply function on the Apple Watch.

Overall, smart functions on fitness watches are far more limited than those of conventional all-rounder smartwatches.

By the way, you can find our review of the best smartwatches here.

Other points to consider when buying a fitness watch in the UK

In addition to training support and the smart functions of fitness watches, there are a few other points to consider when shopping for your device.

To make sure you find the right wearable for you, we have put together a list of other aspects to look out for. 👇

Operating system: Is the fitness watch compatible with your mobile phone?

Of course, your fitness watch must also be compatible with your smartphone.

Here's some good news for you: most fitness watches can be used with both iPhones and Android.

A smartphone and fitness watch placed beside each other.
Garmin Fenix 6 Pro

Manufacturers such as Polar or Garmin have developed their own operating systems.

If you are unsure whether a wearable can be used with your mobile phone, simply search for the companion app to the fitness watch in your app store. 📱

If the app is available in the app store, then the fitness watch can be used with your mobile phone.

How long is the battery life?

Battery life is of course particularly important when choosing the right wearable. 🔋

After all, how long the battery lasts determines how long you can use your fitness watch before having to charge it again.

The best fitness watches last from several days to over a week with average use. 🥳

Of course, conventional all-rounder smartwatches do not come close to this kind of battery life.

Screens on fitness watches

Both the display and the entire watch itself are pretty resilient, as they are designed for sports and outdoor use.

Attention: Not all wearables feature a touchscreen.

But the best fitness watches included in our review have high-quality colour AMOLED screens to display your data. 🤩

The best fitness watches we have compared are water-resistant up to a depth of 50 metres (5 ATM).

Style - another important factor

Since fitness watches are primarily designed for sport and are therefore particularly robust, they naturally tend to look a little chunkier than conventional smartwatches.

Fitbit fitness trackers are an exception here. They also look good with a chic suit or evening dress.
A chunky fitness watch is seen.
Garmin Fenix 5X Plus
You can see the design of the Apple Watch 7.

Most manufacturers offer their sports watches in different sizes.

For ladies, the slightly smaller version is usually recommended. 💃

Otherwise, however, the style is purely a matter of taste.

Here, you can find everything about the best smartwatches for women and the best smartwatches for men.

Comfort of your fitness watch

Of course, a fitness watch should not only track your fitness data, but also sit comfortably on your wrist.

A comfortable silicone wristband is usually a better choice than a chic leather strap when it comes to training.

Also, make sure that the wearable is fastened tightly on your arm, at least during your workout. This way, your data can be measured more accurately. 🙌

Caution: Particularly large and clunky fitness watches could interfere with your sleep and are therefore not suitable for sleep monitoring.

Prices ranges of the top fitness watches

Of course, price is also an important decision factor when it comes to choosing a suitable wearable.

The best fitness watches from manufacturers such as Garmin or Polar tend to come with a higher price tag. 💰
