A smartwatch is a wrist gadget in a form factor that resembles a watch. The gadget can display the time, but also offers a number of features that are not typical for classic watches and smartphones. It is usually equipped with a Bluetooth module for connecting and syncing with your smartphone, an accelerometer that allows you to track your activity, and a vibration signal. This is the minimum set. The rest of the collection of hardware and software capabilities of smart watches is dependent on the specific model. 

A smartwatch is a faithful companion to a smartphone. Initially, these gadgets had a fairly simple functionality and worked exclusively in conjunction with phones, via bluetooth connection. Today they have become significantly smarter and can act as their own device. 

Of course, a full-fledged replacement of a mobile phone with a clock is impossible, but in some situations they can become an alternative – at sports training or at home, you can receive notifications and calls to the clock, and if necessary, go to another room for a full-fledged gadget. It is worth noting that there are devices on sale with a SIM card that allow you to make calls directly from them. However, they have not received wide distribution and are more an exception than a trend.

There are many types of smart watches – they are for children, sports options with increased protection against shock, moisture and a number of useful functions for training or on a hike, there are also classic models that are closer in spirit to mechanical devices than electronic counterparts.

1.1 History

The first smartwatches in the modern sense appeared back in 2010, when even the concept of such a thing did not exist. The model was called the Sony Ericsson LiveView. Two years later, Sony released a SmartWatch model (actually, this is the first use of this word in the product name). And a year later, the SmartWatch 2 appeared

Around the same time, rumors began to spread that Apple was going to release a smartwatch. In 2013, everyone was waiting for the announcement of Apple’s watch, but it never arrived. However, in the Wake of these rumors, interest in a new type of devices has gone far beyond connoisseurs of high technology and techno geeks. Samsung decided to play on this and introduced its Galaxy Gear watch in the fall of 2013, which immediately became the center of attention (despite a number of imperfections).

2014 was a real heyday of the smartwatch industry. First, in the spring, several new Samsung models were presented, which are already much more advanced than the first-generation Gear watch, and secondly, in the summer, the Android Wear operating system was released, developed by Google specifically for smartwatches. And soon on the shelves of stores appeared the first watch on this OS. It was the LG G Watch.

Unlike Samsung and Sony (and later Apple), Google does not release its devices on this OS, but licenses it to other manufacturers. Thus, companies that want to release smartwatches can avoid the headache of developing their own SOFTWARE. During 2014, several Android Wear models appeared on the market at once — including the first smartwatch with a round screen: Moto 360.

And in the fall of 2014, another turning point took place: the long-awaited announcement of the Apple Watch. As expected, Apple came up with a lot of interesting things there, although some received the announcement with skepticism — inflated expectations worked. But the main thing is that Apple has outlined a new trend: smartwatches should now come in several sizes and body options, with many options for straps. 

However, the Apple Watch went on sale only in the spring of 2015. But it also spurred competitors, who not only improved the software and hardware of their existing model lines, but also released new devices, following Apple’s lead in providing customers with a wide range of aspects related to the appearance of the watch. We are talking about models of Samsung Gear S2 and Gear S2 Sport, Moto 360 of the second generation, Asus ZenWatch…

At the same time, all new versions of smartwatches from smaller manufacturers appeared, and they often experimented more boldly with the functionality and appearance of their devices than the grandees. Consider the pebble startup that came up with the idea of using a non-dimming E-Ink screen, or the Withings company that built “smart” capabilities into a classic dial.

But the result of this was a blur of the very concept of “smart watches” — now this device can perform completely different capabilities than the first smartwatches, however, without being able to do what the pioneers did. Therefore, it is necessary to figure out what kind of smartwatches are available.

1.2 Features of Smartwatch

Whether the watch is designed for everyday use (like the Apple Watch) or for a specific purpose (like the Garmin Fenix), most smart devices offer the following set of standard features:

Notifications: The watch displays notifications to alert the user to important events or activities. These notifications come in different types: devices connected to a smartphone can simply display notifications from the phone on the wrist, however other smartwatches display notifications that only a wearable device can provide. 

For example, the most popular Apple Watch has a fall detection sensor: if the user falls and has a watch on, the device will try to recognize subsequent movements; if it doesn’t find them, it will send a series of incremental notifications. Then, if the user does not respond to notifications within a specific time, the device will consider that he has lost consciousness and alert an ambulance. And this is really true, since there have already been quite a few such cases in the world. For instance,

Apps: Smart watches not only display notifications from the phone, but are also capable of launching various applications. Ecosystems, of course, differ, but mostly devices are tied to Apple or Google stores. Smartwatches with a special purpose, such as hiking or diving, usually support the apps required for those sports without the option to add other types of apps.

Media control: Most smartwatches that can pair with smartphones provide media control capabilities. For example, when you listen to music on your iPhone using Apple AirPods, you can use your Apple Watch to change the volume and switch tracks.

Voicemail: Remember the old Dick Tracy comic, where the hero detective used his watch as his phone? Modern smartwatches running the WatchOS or Wear OS operating systems are capable of recognizing the user’s voice.

Fitness tracker: If you are an avid athlete, then a dedicated fitness tracker is probably the best choice over a smartwatch. However, many smart device models include a heart rate tracker and pedometer to help you track your workout.

GPS: Most smartwatches are equipped with GPS, which helps to track the user’s location and receive various notifications.
Battery life: modern smartwatches are equipped with good batteries that can last all day with active use. Timing varies, of course, with the Apple Watch typically going for 18 hours on a single charge, while the Pebble up to three days.

1.3 Operating systems for smartwatches

Today there are three main (non-experimental) smart watch systems.


Apple’s OS for Apple Watch. The menus of the system are implemented using Carousel technology, which in theory should help increase usability. Initially, it was produced as an add-on to the phone, but modern watch models on this system are independent gadgets, although the portfolio of applications for them cannot boast even half of the capabilities that are available on the iPhone.


Taizen is an open source operating system based on the Linux kernel that manages a very wide range of technologies, from mobile gadgets to smart home devices. Developed by Samsung and Intel, respectively, many smartwatches from Samsung – for example, the updated Samsung Gear line and Samsung Gear Neo – are controlled by this particular operating system. The OS is served by the Tizen Store app bank.

Pebble OS

Authentic Pebble system for in-house smartwatches. The main idea of ​​the OS is to provide the user with maximum opportunities for remote control of a mobile gadget. Pebble and Pebble Steel working on this system (especially in conjunction with the Tasker and Autopebble applications) are full miniature copies of all the device’s functions right on the wrist. Pebble OS works with both Android and Apple.


Smart watches are usually divided into three main types according to the principle of operation, functionality and design.

Kids smart watch

Features of smart watches for children are the mandatory presence of a GPS module and a SIM card slot. GPS is needed to track the location of the child using a mobile application or online tracking service. Smart watches for children, as a rule, are equipped with a wiretap – by calling through the application on the child’s watch, parents can hear what is happening near the clock, while the child will not know about the incoming call.

Main functions

  • Time and date display.
  • Cellular.
  • GPS navigator.
  • SOS button – emergency call to a contact by pressing one button. Optionally, the function can automatically send SMS messages to whitelisted contacts or audio recording in a few seconds.
  • Limited list of contacts, programmable via mobile application.
  • Removal sensor – sends SMS simultaneously to three contacts (you need to enter through the application) when removing the Smart Watch from your hand.
  • Alarm clock.
  • Pedometer. 

Additionally, a flashlight, calendar, camera, game applications, etc. can be installed.

Hybrid smart watch

Hybrid gadgets work similarly to conventional smart devices – they are paired with a smartphone via Bluetooth and controlled through a special application. Externally, the models look like a classic mechanical watch, but at the same time they have the following functions:

  • Pedometer;
  • Notification and notification of calls, SMS, messages, etc .
  • The calendar;
  • Alarm clock.

Smart watch

Electronic gadgets equipped with a large display and working in conjunction with a smartphone have a large number of functions and capabilities. However, their main task is to display information from a mobile phone on their own display. This is especially true when the smartphone is nearby, but there is no way to constantly pick it up, for example:

  • While playing sports;
  • When the phone is in the bag and the user is traveling in public transport;
  • At home, when the phone is on charge and the user is moving around the rooms.

Externally, smart devices can be rectangular, round, square, made in styles: sports, classic, male and female.

Smart watches are usually distinguished by purpose :

  • For travelers – designed for long trips and tourism. They have a long battery life, dust and moisture protection, shock resistance, and are equipped with a GPS navigator and monitoring of vital signs of the body.
  • For diving – waterproof models capable of working at great depths. The diving smartwatch has special features that show dive depth, ambient temperature, dive time, etc.
  • For aviation – rare models capable of monitoring the level of oxygen in the blood, showing the weather forecast and an interactive GPS map in real time and keeping a logbook.

Chapter 3: FUNCTIONS

A smartwatch is equipped with many different functions, so it can be a really good helper in many different ways. In addition to numerous sensors, they are able to synchronize with smartphones; many models have touch screens, as well as a GPS navigation system, a fitness tracker, etc.

All functionality can be conditionally decomposed into separate categories:

Sensors that allow you to obtain information from environmental factors, such as pressure, air or human body temperature, compass, etc.

  • The fitness tracker allows you to set up a workout, as well as receive data on the number of calories burned, distance covered, movement speed, individual devices can even count the number of jumps on a rope, etc. It is very convenient to be able to monitor your own body;
  • Synchronization with smartphones. Most devices interact with smartphones only via Bluetooth, others work independently, but synchronization is still possible. Thus, the watch can display messages received by phone number or from social networks;
  • Working with external devices. Developed smartwatches can interact with other digital technology such as light bulbs that change color and brightness. Special vehicle applications are being developed to control lighting, monitor battery charge or fuel level in the tank.

Chapter 4: Benefits of Smartwatch

Always stay in touch

Today, many people take out their smartphone every half a minute to look at the next notification. With a smartwatch, you can safely keep your phone in your pocket or bag without having to worry about missing an important call or message. 

When a call interrupts you while you’re talking to someone, you don’t have to apologize, interrupt the conversation, or reach for the phone to find out who’s calling.

Smartwatches can notify you of incoming text MESSAGES, messages in messengers, social networks, and emails — and many models can even display text messages on the screen. However, if you often use messengers, expect that the clock will constantly distract you with notifications.

Smartwatches will help you not only receive messages and answer calls, but they can also control your smartphone’s media player, camera, work as a hands — free headset (thanks to the built-in microphone and speakers), and sync with your smartphone’s calendar.

Smart alarm clock

Many modern wearable devices can be used as a smart alarm clock, and smart watches are no exception. What kind of function is this? A separate app or built-in watch option uses an accelerometer to monitor your sleep activity, determining from your movements exactly what phase of sleep you are in. 

A smart alarm clock will Wake you up in exactly the phase in which you are most likely to Wake up awake — the REM sleep phase. By the way, the phases of slow and rapid sleep change each other several times during the night. Example of how an alarm clock works: you set it, for example, for 7 a.m., and the clock wakes you up at 6: 30, because that’s when it records the transition to REM sleep. 

As a result, you may not sleep for half an hour, but you will Wake up more alert than at 7 o’clock. In the words of Steve jobs, it works like magic


Let’s face it. People love to be aware of everything that is happening around. They want to feel involved in what is happening. This is what makes smartwatches so attractive to most consumers. Imagine that you can do all those operations for which you had to take your phone out of your pocket in a matter of seconds, without even having to take your phone out of your pocket. Fantastic, isn’t it? With smartwatches, this has become a reality. Smartwatches allow you to make and receive calls and receive important updates. You can receive text messages, alerts and updates in an unobtrusive manner.

The freedom of action

Everyone wants to be connected, but let’s face it, there are places where talking on the phone is simply inappropriate. It doesn’t matter if they are your relatives or very important clients. There are situations when talking on the phone is inappropriate, indecent, or inconvenient. In this case, a smartwatch will come to your aid, which allows you to check and send messages on the fly.


Unlike some new technologies, smartwatches have fairly affordable prices. Since they are the perfect complement to smartphones, more and more companies selling cell phones and their accessories are selling and promoting them in the market. Moreover, even the most long-awaited smartwatch model is very affordable. As more and more companies want to jump on the bandwagon of the “smartwatch market,” the functionality of smartwatches is increasing and prices are falling rapidly.

Personalized firmware

App developers have complete leeway when it comes to developing apps and smartwatch firmware. Companies are stimulating interest in developing innovation in this area by creating guides on how to hack smartwatch software. Similar to smartphone apps, smartwatch apps can be very interesting.

As you can see, there are a number of reasons why people would want to use a smartwatch. In a recent study, researchers found that the average smartphone user checks their phone up to 150 times a day, or once every 6.5 minutes. It’s amazing how much time we spend on our phone! Wouldn’t it be a bad thing to do the same thing in less time?


Decide why you need a smartwatch

First of all, you need to ask yourself the question: why do I need a smartwatch at all? What do I want from them? As a rule, there are several most common options here. The first: “just curious what it is”, “everyone says, so I decided to buy something like this”. 

In General, you do not know why, but you are interested in trying. So this is an experiment for you, a toy. In this case, if you have an Android smartphone, it makes sense to take some inexpensive model on Android Wear. 

For example, the Asus ZenWatch 2 or the first-generation Moto 360. Or even some Chinese craft on Android Wear. If you don’t like it, if you get bored, you won’t feel so sorry for the money you’ve spent. But you will get an idea of the capabilities of a smart watch and get enough of it.

If you have an iPhone, then, of course, first of all you will think about the Apple Watch, but they are very expensive (even the most affordable option), and for the sake of experimentation, not everyone will decide to spend such money. 

So if you want something that is more accessible, but still opens up the potential of this class of devices, pay attention to Pebble. The first plastic pebbles can now be found in Russia for 10 thousand rubles. Not to mention the options for buying with your hands. Well, or much more expensive and original Pebble Round (we mentioned them above).

The second option to answer the question about why you need a smartwatch: “I want to get notifications, see who calls or writes to me.” Indeed, this is one of the main purposes of smartwatches. This is especially convenient when walking or driving: you do not need to take out your smartphone, you can look at your hand — and understand whether it is worth reacting somehow or not. 

The third option: “I need fitness functions like step tracking, but I want a watch, not a bracelet or fitness tracker on a clip.” And the fourth option: “I want a stylish wrist accessory that would not only demonstrate my taste, but also position me as a person advanced and not alien to high technology.”

If you choose the second, third or fourth option of the answer, then the design of the watch will be of fundamental importance for you, since you are buying something that you really want to wear every day, and not just want to play for a week or two. And here we can immediately give you a second tip.

Appearance and materials

Of course, design is important for smartphones, tablets, and even laptops. But if you interact with these devices from time to time, then the watch on your hand is constantly on, and you look at it much more often during the day than on your smartphone. 

The watch may be more functional or less functional, but it should definitely please you with its appearance. Ultimately, a smartwatch is not a basic necessity at all. Their presence will not affect (or minimally affect) your work productivity, and they will not replace other devices. So what matters is not what they can do, but how they look and feel to you. 

In General, listen to your taste. For example, if a smartwatch for you is primarily a fitness device, then you can generally not even look at the characteristics and just buy the one that you most like in appearance. Because the accelerometer works about the same for everyone. However, we will make a reservation that we do not mean professional sports GPS watches here.

Think in advance about the straps.

Even the most beautiful watches that you really like can get boring one day. And then the question will arise: how and for what to change the complete strap? And here the number of options varies greatly depending on the watch model. 

Therefore, it would be most prudent to think about this in advance, even when buying a watch. It is worth paying attention,first, to the very fact of whether the watch strap is removable or not (and here our reviews can help you, where it is always mentioned!), and secondly, to the availability of straps for this model

The best situation is with Apple Watch straps. They can be found in a wide range of online and offline retail outlets. Almost all branded Apple Watch straps are beautiful (especially if you don’t make a mistake with the color). But they are very expensive. Of course, there are already quite a few third-party straps. However, there is already a high risk of buying something mediocre.

By the way, a well-chosen removable strap can radically change the feeling of smartwatches and their appearance. For example, with a leather strap, any model looks more serious and expensive, but with a silicone strap, it is more convenient to exercise in a watch. 

Men may also be interested in models with a steel bracelet, but here the choice is still small: either the expensive Apple Watch (more precisely, the expensive bracelet itself, for which they ask almost as much as for the watch), or the Moto 360, or the Huawei Watch (this is also not a cheap option, although much cheaper than the Apple Watch).

Ignore the CPU, RAM, and amount of flash memory.

“How so?” you will exclaim. Here it is. These are not smartphones or tablets. It doesn’t matter here. At all. Generally. In terms of performance, all smartwatches are the same. And if something slows down — it’s because of software, and not because of a weak processor or not enough RAM.

Screen — AMOLED is better.

If in the case of smartphones, there is still a debate about whether AMOLED or IPS is better, then for smartwatches, the answer is obvious: AMOLED is better. Because clock accuracy is not so important (you’re not going to watch hours of movies and photos!), but the important richness of colors, depth of black and efficiency when displaying black, the AMOLED seems to be the best choice.

However, an even more important parameter is the shape of the screen. Want a Moto 360 with a round IPS screen? Do not deny yourself because there is no AMOLED. When choosing a smartwatch, the shape of the screen is more important than the matrix and resolution used.

Tracking your physical activity. Many smartwatches are able to perform the functions of a fitness tracker, at least to calculate the steps taken, distance and number of calories spent during training. Many devices are also equipped with a heart rate sensor, and can automatically detect the beginning and end of a run or workout, and even count the number of sets for each exercise. More advanced models, such as Suunto 3 Fitness and in General, can themselves make a workout plan for you, based on your body’s performance.


Save time

With the help of these hours you can quickly write a message to a friend, or to check the time. Agree, when you take the phone out of your bag/pocket it will take time, when you can get your hand out and look at the time on it, send a message.

The watch can also vibrate when you receive a notification. Otherwise, the notification may be quiet and you won’t hear it. And in addition, you cannot smell the vibration from the bag, but when your hand appears “earthquake”, then you immediately feel the vibration.

2. Live longer!

Many watches already have a function to view your heart rate, calorie counter, “pedometer” and other functions to monitor your health. Let’s say you’ve traveled quite a long distance, and you need to see how far you’ve already traveled? Then the problem is solved!

Or for example, if you ate in a restaurant, and you “watch” your weight, and you need to find out how much food you ate? Then you need to look at your watch, and it will give you how many calories you have consumed.

More voice services, more hell!

For smartwatches, people ported such popular voice services as Apple’s Siri and Samsung’s S Voice to quickly type messages to people. Only the sad thing is that Apple will probably only install Siri on its smartwatch, which is the same as Samsung.

You can also dial a voice message using a smartwatch without taking out your phone, which gives you a + towards smartwatches.

Smartwatches are more discreet than phones… and Google Glass.

Let’s say you need to quickly write off a test on the Internet, but if you take your smartphone, then you will be noticed, and if you take into account the fact that Google Glass is banned in many countries of the world, then the eye falls only on smartwatches.

As you can see, there are a number of reasons why people would want to use a smartwatch. In a recent study, researchers found that the average smartphone user checks their phone up to 150 times a day, or once every 6.5 minutes. It’s amazing how much time we spend on our phone! Wouldn’t it be a bad thing to do the same thing in less time?
