How to choose a smart watch

Smart watches are practical, stylish, they are simply in. I can reach young, old, women and men. Choosing the right smart watch could be compared to choosing a smartphone. There are currently a large number of types, models and features on the market that need to be considered. Before buying them, you need to think about what you expect from them. That is why we have decided to make it easier for you and we bring you an overview of criteria and features that you will definitely appreciate when choosing a smart watch.

What type of watch

The basic division of smart watches is based on the method of use.

Smart watch

Mostly it’s a design piece that brings features from connecting to a smartphone, such as making phone calls, sending messages, receiving notifications from applications, and even waking up. Wearing a smart watch is like having a mobile phone with you at all times, even if you don’t have it right in your hand. If you opt for a smart watch, you will no longer miss missing a call just because you have turned off the ringtones or your cell phone in another room. You can control the watch by voice and it will quickly become your helper even in situations where you would not expect it.

Sports watches

If you are an active athlete and you do not have enough basic fitness functions offered by classic smart watches, such as a pedometer or heart rate monitor, there is a special type of watch with advanced sports functions. They have quality sensors for the most accurate values ​​available, the durable body is adapted to sports, so the watch is more robust. They will become your partner in every physical activity, whether you decide to run a marathon or swim a few lengths in the pool. The watch records and analyzes every sports activity. They are more suitable for active athletes who engage in physical activity often and for a long time.

Fitness bracelets

Fitness bracelets resembling smart watches are still popular. They also offer some smart features, such as step or heart rate measurement, and compared to real smart watches, we can buy them for a much lower price. Although the measured values ​​are not very accurate, they are sufficient for casual athletes. The display is usually smaller and we will find fewer functions here, but they are easy to carry and will not burden your budget.

What to focus on

There are a lot of features and functionalities to look at. First of all, you need to choose the already mentioned type of watch. Since the connection of the watch to a smartphone is important for the functionality of the watch, it is necessary to consider the compatibility of the watch with your mobile phone when choosing. If you already know what type of watch you want and which smartphone you are going to connect it to, you must also take a good look at the display that the watch offers. Other important features are battery life, durability, connectivity, message and call control, advanced fitness functions, overall design and, last but not least, the price of the watch.


Smart watch compatibility is closely linked to the operating system under which the watch runs. There are currently models on the market with three operating systems, each of which is adapted to connect to a different type of smartphone. These are the operating systems Wear OS, Tizen and WatchOS. In addition to these, there are other operating systems for smart watches, but their market share is declining.

wear OS

The watch from the Wear OS by Google edition is ideal in conjunction with the Android system (in the past, it was even called Android Wear 2.0). In addition to connecting to Android phones, they provide partial compatibility with Apple smartphones. They offer their users thousands of applications available on the Google Store, but it often happens that the application is not completely adapted for use on a small smart watch display. The disadvantage of this OS is that it is adapted to a large number of watch manufacturers and models, so models with this operating system are slower and often get stuck.

Advantages: Lots of applications, frequent upgrades, good price

Disadvantages: Limited compatibility with iPhones, lower quality applications that run on watches, slow running

Tizen OS

This operating system is specially adapted to Samsung products, so it works smoothly and quickly and the devices have a longer battery life. The online application store offers a wide range of choices, but not as extensive as the Wear OS.

Advantages: Hardware optimization, battery life

Disadvantages: Compatibility limited to just a few devices, higher price, fewer applications


Apple Watches with the WatchOS operating system are specially designed for owners of Apple devices. They will appreciate not only the connection of the iPhone with the watch, but also the connection of the entire Apple ecosystem. These include details, such as automatically unlocking your MacBook when you’re sitting with your Apple Watch. The disadvantage is the incompatibility with other types of mobile phones and the smaller number of applications available in the Apple Store.

Advantages: Smooth and fast running, connection with the Apple ecosystem

Disadvantages:Compatibility limited to Apple devices only, higher price, fewer applications


Square or oval? This is probably the basic question to be answered when choosing a display. Oval displays evoke the feeling of a classic watch and are often larger. Applications running on an oval watch have a problem with responsiveness and overall customization. You have to get used to the square display, especially if you have only worn a classic watch so far. In addition to the shape, the type of display must also be considered. Most smart watches use an AMOLED or OLED color display and a plastic protective glass above it. On more durable watches we find protection in the form of Gorilla Glass. It is also important to adjust the size of the dial of your hand so that the watch does not interfere with your work.

Battery Life

Color display, GPS sensor, active notifications, all this reduces the battery life of the smart watch, which ranges from one to three days. Therefore, like smartphones, the watch must be charged frequently. There are also models on the market with wireless charging, which is much more comfortable. Fitness bracelets, whose battery lasts about one to two weeks, have a huge advantage in this regard.


If you want to use the watch for sports activities, you will certainly appreciate its resistance to dust, scratches or water. If you are looking for a watch that you can swim with without worries, look for at least IP67 certification, which allows immersion to a depth of one meter for 30 minutes. IP68-certified models are more ideal, with which you can swim up to a depth of 1.5 meters. In both cases, the watch is dust-resistant. In addition, the water resistance of the watch is indicated by atmospheres, for example 5 ATM means that the smart watch is waterproof to a depth of 50 meters. For models with such data, you do not have to be afraid to go swimming even longer routes.


The smart watch connects to the mobile phone using Bluetooth technology, which only works over short distances. Some models have Wi-Fi connectivity. If your phone and watch are on the same Wi-Fi network, you can control them from a greater distance than with a Bluetooth connection. This feature will be appreciated by people working in large buildings covered by Wi-Fi. If they go to a meeting on another floor and leave their mobile phone in their office, they will always have it with them through their smart watches on their wrists. If you want to use the watch without having to connect to a smartphone, be sure to look for models where you can insert the SIM card directly. If you want to use the option of contactless payment using a watch, you must have the NFC function.

Control messages and calls

Some smart watches allow the user to answer and reject calls directly from the watch. In some models, answering a call is activated by the microphone and speaker on the mobile phone, other models allow you to answer and have a conversation directly from the watch. You can leave your mobile in your bag or pocket. The same principle works when receiving and sending messages, some models only alert the user, others allow you to respond directly from the watch.

Advanced fitness features

You go jogging, so you start the activity of running outside and your watch calculates the distance traveled, calories burned, the cant overcome, the course of your heart rate, and if you have GPS, also a map of the route you have traveled. Not only running, but also other sports activities can be mapped through fitness functions, whether it is cycling or snowboarding. Some models also offer the option of setting goals along with tracking weight and menu. If you are a competitive type, you will also appreciate winning various awards and medals for physical activity. More expensive devices can even recognize some types of sports activities, such as running, walking or swimming, automatically without user intervention.

Watch design

Smart watches are basically design accessories and many of them offer interchangeable straps to match you at every opportunity. Leather, rubber, fabric, elegant or sporty, you can find countless looks of watches, you just have to choose the right ones.
