Here we had listed out some of the best fitness watches with the advanced features that are present below.

Buyer Guide to Choose the Best Fitness Watches

Display

The display of a fitness watch can have different sizes and shapes. There are, in fact, models that use a circular dial, but there are several models that adopt a square dial, such as Apple’s Apple Watches.

In any case, the panel resolution is indicated with two numbers, for example, 240 × 240 pixels. In this case, the presence of 240 pixels (points) is indicated for both the horizontal and vertical sides.

As happens on smartphones, TVs, and other types of displays, the resolution does not indicate the dimensions of the panel (which are declared in inches or millimeters ), nor its definition, but only the calculation of pixels present inside the display.

The more advanced models can also have a touch-screen, i.e., a touch-sensitive panel as a command input mode, others have physical or capacitive keys, wheels, and other input modes.

It is however more interesting, on a smartwatch or on a smart band, to speak of the type of integrated panel: many models make use of OLED displays, which consume less than traditional LCD (liquid crystal) and which manage to turn off the pixels to reproduce the black (they are very bright and can reproduce perfect black in the dark).

Unfortunately, very few fitness watches with e-Paper displays, a particular type of technology similar to that found on e-book readers, which offer perfect visibility under the sun and at the same time consume energy only when the status changes.

Pay attention to the models with the always-on function. Are you wondering what it means? I’ll explain it right away: this is a mode that allows you to have the basic information always active on the screen.

The always-on displays are, in fact, always on thanks to an advanced energy-saving mode, which is deactivated when you bring your arm upwards as if you wanted to read the time, or by making a “tap” on the dial.

Smartwatches or smart bands that don’t have this feature usually show the black dial when they are in use. Finally, check the data on visibility under sunlight, an essential part of a fitness watch as you will often use it outdoors.

Water Resistance

It is not uncommon to use a fitness watch outdoors or in less than optimal conditions, such as when it rains. There are also models on the market with the possibility of analyzing swimming activities, and it is clear that they must be able to function even when immersed underwater without the risk of breaking.

For this purpose, there are several standards that define the ability to withstand in certain circumstances: for example, we have the IP certification, also common to smartphones, but often on smartwatches, sports watches, and smart bands, we read the word 3ATM or 5ATM.

The first declares that the device can be used within certain time limits at a maximum depth of 30 meters, the second instead that it can also reach a maximum of 50 meters in depth.

Strap

The strap is an essential component of a fitness watch since it establishes how comfortable it is and how easy or difficult it is to unfasten in the least suitable moments.

You can get an idea in this sense by reading the reviews online on the most reliable sites. However, to date, almost all fitness watches on the market offer the possibility to change their strap with universal or dedicated models for each specific model.

As a rule, the most famous models offer a vast possibility of changing the strap, with shapes, materials, and colors that adapt to every need.

The straps can have multiple sizes: the one relating to the size of the wearer’s wrist, often indicated with the letters S (Small), M (Medium), L (Large); or that relating to the width of the strap (often in millimeters), which can be useful if you want to change the strap and want to buy one compatible with your smartwatch.

Operating Systems and Compatibility

Another fundamental part of a fitness watch is the operating system, i.e., the essential software that interfaces with the components and, above all, the software with which it is possible to issue commands.

Each operating system is compatible with certain devices, so always check if you can pair your smartphone with the watch you want to buy (for example, to read the notifications, to manage some features, or even to synchronize the fitness data collected for more comfortable reading).

Professional sports watches often use a proprietary operating system, which often boasts the ability to connect with many different smartphones without, however, going deep.

Battery

The battery is a very delicate component in a smartwatch since it is usually minimal and should guarantee days of autonomy. Often, needless to say, this is not the case, and many smartwatches – including the latest generation – also struggle to arrive in the evening.

The battery capacity is indicated in milliampere hours ( mAh ). However, there are so many variables that can affect the autonomy of a fitness watch that the declared number does not say much.

Display width and resolution play an essential role in energy consumption, and the always-on mode is also very “heavy” to manage in this sense. Among the functions that most compromise battery life, there is also the use of the GPS module, capable of reducing it even to a few hours.

Fitness Functionality

Now that you know the technical rudiments let’s move on to the more practical factors. In fact, a fitness watch is based on the fitness features it includes inside, and often there is no possibility of introducing new functions with dedicated apps.

On many models, in fact, the functions related to fitness that you can use will only be those available for purchase without the possibility of expansion.

Pedometer, Calorie Consumption

The pedometer is probably the most used function within the fitness watch and allows – as you can easily deduce from the name – to keep track of all the steps that are taken during the days.

Almost all models give the possibility to monitor the history of the steps taken daily, weekly or monthly, and at the same time indicate the distance traveled or the count of the floors climbed during the days.

By combining these data with those of the activities carried out many fitness watches also allows you to obtain an analysis of the calories burned in a given period of time.

Heart

Another important aspect of a self-respecting fitness watch is the heart rate monitor, which is a type of sensor – often of an optical type – that allows you to detect the wearer’s heartbeat at any time of the day.

Some models give the possibility to monitor the heart rate 24 hours a day, in order to warn the user when values ​​beyond the norm are found.

The most advanced smartwatch models also have an electrocardiogram (not always of a medical level, however), which allows you to record the frequency and intensity of the electrical impulses that produce the heartbeat, checking for the presence of potentially dangerous cardiac arrhythmias.

Gps Support

If you often do outdoor sports, GPS support is one of the most critical components of the smartwatch that you will want to keep on your wrist.

This component allows you to geolocate the position of your outdoor activities and, in retrospect, to check (through various services) the progress of the training on a map on your computer or smartphone.

In the more advanced models, it is also possible to take advantage of the satellite navigation function, just like on smartphones and tablets.

Analysis of The Activity

The fitness watches are often the activity tracker real, and allow the user not only to analyze the data collected during daily activities and those of gymnastics.

Also, to get advice on how to improve personal well-being, the conditions of health, and performance in gymnastic activities, starting from the same data collected.

Many models synchronize with external services or with apps on smartphones that contain a sort of digital personal trainer able to suggest the best plans to follow to improve physical fitness on the basis of what is observed in the wearer’s sleep and wakefulness activities.

Other Fitness Features

Many fitness watches allow you to take advantage of modes of use designed for specific sports, such as running, cycling, swimming, outdoor excursions, and much more.

Dedicated sports watches can also offer the ability to connect a heart rate monitor, in order to detect more reliable readings relating to the heartbeat, and there are also models that allow automatic recognition of sports activity, intelligently activating the type of activity detected.

Among the most exciting and useful fitness functions, we have sleep monitoring – especially present on smartbands – or the possibility of entering daily goals and following the trend at any time of the day.

Last but not least, the classic functions: a fitness watch cannot fail to have time reading, while, unfortunately, not all models have a stopwatch or timer.
