Do smart watches have internet? Compatibility of smartwatches with other devices

In short, a smartwatch is a faithful companion to a smartphone. They allow you to see a notification with a simple wave of your hand. This is especially true for those people whose smartphone is very large - it is simply inconvenient to take it out of your pocket every time. In this material we will try to answer the most popular questions regarding this type of electronic devices.

It's time to talk about what a smartwatch is for. Please note that features may vary between devices. Some gadgets may be able to do one thing, while others will not be capable of it. If you are interested in maximum functionality, then SetPhone has a selection of the best smartwatches especially for you. Choose one of the devices presented in it - you will definitely be pleased!

So, an approximate list of smartwatch skills is as follows:

• Show notifications that come to your smartphone- this allows you to read any message without removing the device from your pocket, and in some cases also respond to it.
• Simplified operation with alarm clock, stopwatch and timer- again, you don’t need to touch your smartphone.
• Physical Activity Tracking- uses pedometer, heart rate check and other functions. Some models even monitor sleep quality.
• Show your location- even if the watch does not have built-in GPS, the information will be taken from the smartphone.
• Opportunity to talk to someone- Some smartwatches have both a speaker and a microphone built-in.
• Creating shopping lists- in the store you don’t need to constantly stare at your smartphone screen, just glance at your watch.
• Regular receipt of information about the dollar exchange rate or the cost of oil- To do this, you just need to download the appropriate application.
• Showing results of football matches- There are also separate applications for this.
• Play right on your wrist- games for smartwatches exist, even if they are not very sophisticated.
• Time display- yes, smart watches can do this too! It is also possible to display the time of sunrise and sunset, current temperature, probability of precipitation and other information. And all on one dial!

And this is just the first thing that comes to mind for any smartwatch owner. The breadth of functionality depends on the cost of the device and the version of the operating system. For example, the latest watch from Samsung even helps with swimming - it will show you the distance traveled, the number of heart beats per minute, and also give you some tips. In general, smart watches are primarily created for those people who monitor their health.

What smartphones can smartwatches work with?

The choice of a specific smartwatch largely depends on what kind of smartphone you have at your disposal. For example, a Windows Phone-based device can only communicate with Pebble and a couple of other smart devices. Concerning Apple Watch, then this watch only works in conjunction with an iPhone. And this should not be the oldest smartphone, because ancient versions of iOS simply did not know that Apple would someday create its own smartwatch.

The rest of the wrist gadgets are mostly designed for Android 4.4 and more recent versions of the “green robot”. However, exceptions to this rule are possible. Some Chinese devices stubbornly refuse to “see” any specific smartphone models. Smart watches can also interact with iOS. But in some cases, the user is provided with reduced functionality.

Can smartwatches work without a smartphone?

Smart, but not a watch

Nowadays you can find many miniature electronic devices in stores. Theoretically, you could confuse a smartwatch with a fitness tracker, heart rate monitor, sports watch, or even a cycling computer.

Typical cycling computer

Smart watches must have a fairly large LCD display - its diagonal must be at least 1 inch (with the exception of children's models). Another distinctive feature of smart watches is the presence of an operating system or fairly advanced proprietary firmware. For example, functionality Sony SmartWatch 2 is provided by Japanese-developed firmware, but this does not negate the fact that additional applications can be installed. And the clock Moto 360 work using Android Wear - a special version of the “green robot”. There are also a lot of Chinese smartwatches that have regular Android installed.

In short, any smartwatch supports the installation of third-party applications. Although there are exceptions to this rule. There are mechanical watches that can only notify about incoming calls and received SMS. This notification is implemented through vibration and a flashing LED - there is no talk of any LCD display or operating system here. But such devices are more likely just watches with an additional function, rather than some kind of smart gadget.

How often should you charge your smartwatch?

Unfortunately, the small battery takes its toll. On average, smartwatches need to be charged once every two days. Expensive models can boast battery life for three to four days if you do not use GPS. Cheap Chinese products may require connecting a charger by the evening. This is due to the fact that regular Android is not at all optimized for a small device with a tiny battery. Android Wear is better thought out in this regard. Just like the operating system created by Apple.

In many ways, the battery life depends on how exactly the watch is used. If you turn on the GPS and go for a bike ride, then any device you have will be discharged by the evening. On the contrary, if you only read notifications, then the charge lasts for a longer time.

Is it possible to connect a headset to a smartwatch?

It all depends on the specific watch model. Many of them do not allow you to talk to your interlocutor or listen to music. It is basically impossible to connect a headset to them. Other watches are more functional - they often allow you to connect a wireless headset via Bluetooth. And on some devices there was even room for a traditional 3.5 mm audio jack.

Can I use my smartwatch in the rain?

The vast majority of electronic devices that exist today are terribly afraid of water. But many smartwatches have one or another water protection standard. Be sure to check it out by reading the specifications! If a standard is specified IP68, then theoretically you can swim and dive in the pool in this watch. Other watches are not afraid only of splashes - that is, rain. There are also completely unprotected gadgets.

Note: The touch screen of many watches begins to make false alarms when raindrops hit them. There's nothing to be done about it.

How much do smartwatches cost?

Like smartphones, these devices are completely different. In Chinese online stores you can easily find smart watches for 4 thousand rubles. But you shouldn't expect much from them. More functional options cost from 6 to 12 thousand rubles. For this money, theoretically, you can even find a device with Android Wear on board.

The most functional watches cost significantly more. For Samsung and Apple products you will have to pay more than two tens of thousands of rubles! There are also smartwatches from TAG Heuer, Casio and all sorts of fashion companies - they can cost even more.

What does a typical smartwatch consist of?

Modern smartwatches are similar in design to traditional smartphones. If we leave mechanical watches out of the equation, the list of main components will be as follows:

• Case and strap- can be made from a variety of materials. Most often, the body is made of metal (at least partially), since its interaction with the skin will definitely not cause an allergic reaction.
• CPU- a low-power chip is used, created using ARM architecture, as in all smartphones.
• LCD display- can be round or square, manufacturing technology can also be different.
• Speaker- not present in all watches; some devices notify about any events only by vibration.
• Microphone- if it exists, then you can use it to give commands to the voice assistant.
• SIM card slot- allows you to access the Internet using a mobile operator. The slot is not present in all smart watches, as it takes up a lot of space. There are also models with a virtual SIM card, but at the time of writing (summer 2017), Russian operators do not provide such a service. Sometimes the SIM card is used only for sending SMS.
• RAM and permanent memory- in the first, currently running applications store their information, and in the second, you can save music, photos and other files.
• Camera- a rare guest in smartwatches, since it is impossible to place a decent module in such a miniature device. Yes, and using the camera on the watch is inconvenient. And in some countries, smart watches with a camera can be classified as prohibited spy devices.
• Heart rate monitor- present in fairly expensive gadgets, it works using a green LED or some other technology.
• Battery- usually its capacity does not exceed 300 mAh. The operating time of the device depends on the optimization of the operating system, the number of wireless sensors, the type of installed screen and many other factors.
• Bluetooth and Wi-Fi modules- with the help of the first, the smartwatch is synchronized with the smartphone, and the second plays an auxiliary role.
• Module- speeds up the first connection to a smartphone. It can also be used to implement a wireless payment method.
• Controls- watches almost always have at least one physical button. Samsung devices use a rotating bezel, which allows you to select menu items without your fingers blocking the screen.
• Light sensor- present in many devices, with its help the system automatically adjusts the brightness of the screen backlight.
• Accelerometer and other motion sensors- they can turn on the display backlight the moment you raise your hand with the watch on your wrist. The pedometer is implemented in a similar way.

Where can I buy them?

Buying a smartwatch is not as easy as it seems. They cannot be called very popular, which is why some stores refuse to sell them. But you can find them in DNS, M.Video, Eldorado and other large retail chains - at least in big cities. They are also sold by many Russian online stores, including those owned by the manufacturers themselves. The easiest way to order cheap smartwatches is on Chinese online platforms.

Brief history of smart watches

Many large companies have long tried to provide electronic watches with additional functionality. Surely you remember that the clock Montana had a stopwatch, alarm clock and several melodies. But even before them there were clocks Pulsar, which had programmable memory. You should also be familiar with calculator watches, the miniature keyboard of which had to be pressed with a toothpick.

In 1984 the watch was born Seiko RC-1000. This device could be connected to a computer! We can say that it was from this moment that the history of smart watches began. Although the first gadgets could not be called smart. They only had apps for notes and scheduling, as well as a world clock and a calculator.

At the beginning of 2000, IBM showed a clock that operated using Linux. But then things didn’t go beyond the prototype. The smartwatch segment in those days was supplanted by mobile phones, which became smaller and more convenient. Everything changed in 2013 or a little earlier. Technology has reached the point where watches can be constantly connected to a smartphone. This reduced the load on the processor, and therefore it does not have to be powerful. Everyone has started developing smart watches and their components - Qualcomm, Toshiba, Sony, Foxconn, LG, Microsoft and other companies. Soon they were joined by Apple, whose product further increased the popularity of smart watches.

Once upon a time, smart watches were only an attribute of heroes from science fiction stories and films. It is difficult to say whether the imagination of writers and directors became a prophecy or simply inspired inventors, but for several years attempts began to realize something similar. It’s just that the level of technology development did not allow turning the idea into reality at that time, and very recently devices reminiscent of superhero gadgets were created.

Today, the market for wearable devices, and smartwatches in particular, is developing at a rapid pace, and almost every six months manufacturers demonstrate something new. We have highlighted several reasons that make smartwatches an incredibly necessary and useful thing.

The first reason is quite simple and banal - futuristic gadgets now look much more appropriate than classic watches. Each manufacturer strives to emphasize the individuality of its product, thanks to which you can choose the ideal design - laconic, premium, sporty, universal, and so on.

It’s worth purchasing a smart watch because most modern smartphones are quite large, and a five-inch gadget in your pocket does not add any comfort. By purchasing a smartwatch and syncing it with your mobile device, you can use most of the functions of your smartphone without even taking it out of your bag or pocket.

With a smart watch, you can always stay in touch, because notifications about messages, calls and events on social networks are instantly displayed on the watch screen, notifying you with a sound signal or soft vibration. In addition, you can switch audio files in the player using the watch and even control the smartphone’s camera.

Some smartwatch models can work without a smartphone, which means that their owner will be spared the need to carry a bulky mobile device. These devices usually have a speaker, headset, or headphone jack.

Smartwatches of the latest models are often able to receive a Wi-Fi signal, and they can also be made an access point. The small size of the display is usually compensated by the presence of voice control.

Smart watches will be especially interesting for those who care about their own health and physical fitness. Typically, such devices are equipped with various sensors that allow you to monitor physical activity. If the device runs on the Android Wear operating system, then you can easily install a suitable training application, set goals and analyze the information received to achieve better results.

Losing or forgetting a smartwatch is quite problematic thanks to the reliable strap and built-in function designed to protect against loss. In addition, a smart watch will prevent you from losing your smartphone and will help you find it if you don’t remember where you left it.

Many modern people may be wondering which smartwatch to choose. In 2018, Smart Watches overtook smartphones and fitness trackers in popularity due to their capabilities. This is a universal device that can replace a mobile phone, heart rate monitor, etc. All this is provided by the manufacturer and is included in the functionality of the device. The article will tell you how to choose a smart watch, what it is and whether this device is needed at all.

What is a smart watch

Smart watches are a recent invention in the gadget world. The device owes its popularity to its versatility. Some expensive models replace sophisticated smartphones. Like mechanical products, the device shows the time. However, the built-in functionality of smartwatches cannot be compared to regular watches. The capabilities of the device are discussed in more detail in the paragraph below. Let's talk about the appearance and design of the gadget.

Smart Watch Design

The appearance of the device resembles a wristwatch. For 2018, many types of devices of various forms have been developed:

• Rectangular
• Square
• Round

Some Smart Watches with a round case may distort the image near the frame. Manufacturers of expensive watches have solved this problem. The design of the devices is similar - a screen, a power button on the side of the case, a cord connector (or contacts for a docking station). Many smartwatches have a removable bracelet, which is an advantage.

Functions

To understand what a smart watch is, check out what they can do:

• Calls and SMS are available for watches with a SIM card
• Smartphone control - player, camera, settings, etc.
• Track notifications, alerts and other phone events - available on all models

The capabilities of smartwatches are not limited to the listed functions. Above are just the main ones. Expensive, sophisticated models are compared in terms of functionality to PCs. Special applications have also been developed to further expand the capabilities of the device.

Working with a smartphone

Basically, smartwatches require connection to your phone. Without this, they present only a device with standard functions - date and time display, alarm clock, etc.

Autonomous devices have also been developed. Often these are watches with a SIM card. The ability to work with communications eliminates the need for a telephone. Most users do not take their smartphone with them, preferring a compact wrist gadget.

Value for money

The world's sales leaders - Apple, Samsung, Sony, etc. - produce high-quality products. The devices of these companies are distinguished by a high level of performance, a powerful battery and an abundance of functions. There are also good models among budget watches.

Regardless of the price, you need to check the operation of the smart watch when purchasing. Find out how cheap devices work from customer reviews. Some of them are presented in the paragraph below. Now let's talk about how to use a smart watch.

How to control your Smart Watch

Control features vary among smart watches. Manufacturers strive for a clear interface, so questions usually do not arise. Before you start, set up your gadget.

How to set up your Smart Watch:

1. Once turned on, look at the fields on the screen;
2. Select your time zone if your device prompts;
3. Enter the required information in the boxes - weight, gender, etc.

How to control a smart watch of a particular model is indicated in the instructions. Look for detailed specifications there. The manual is included in the package. If there is no translation into Russian, go to the official website of the developers and download it.

How to choose the right smart watch

Choosing a smartwatch is a responsible matter. The most important point is whether the gadget is suitable for your existing smartphone. Pairing with it is a useful and convenient thing, especially if you need to monitor notifications. To work together, it is not necessary to select a device from the same company (with the exception of Apple and Samsung). Universal samples have been developed for 2018. Make sure to match the models when purchasing. How to choose a device and not make a mistake is described below. Let's talk about whether it's worth buying a smartwatch and why you need it.

Why do we need smart watches?

The question of why smart watches are needed is asked by many buyers. Without trying the device in practice, it is difficult to understand its usefulness and practicality. Most users note the convenience of working together with a smartphone, calling the device a watch phone. Let's talk about why people buy smart gadgets.

To figure out if you need a smartwatch, consider the following:

• This is an innovative device for lovers of smart technology
• The device is compact and is always on your hand, replacing your phone
• You don't need to take the device out of your bag or pocket to answer a call or view notifications
• The device monitors the user’s health by tracking sleep phases, counting heartbeat, etc.
• Multidirectional devices have been developed - for training, golf, rock climbing, etc.

Device selection criteria

Choosing a smart watch is difficult for an inexperienced person. There are many details you need to know regarding image, performance, memory, battery, etc. To make the right choice, follow the criteria below. Descriptions are not always accurate, so please check your purchase in store.

Choosing the right gadget:

1. Turn on the device and look at the image - clarity of the text, brightness of the picture, visibility in the sun and in the dark;
2. Execute several commands - evaluate the speed and accuracy of the device;
3. Check the battery capacity - the more, the better;
4. Make sure there is a slot for a flash drive - additional memory will not be superfluous;
5. Prefer devices with a SIM card - eliminates the need for a telephone in terms of calls and SMS.

Smart watches, or as they are also called smart watches, and sometimes fitness watches, are another niche of “smart” gadgets, the versatility and multitasking of which allows you to use their potential both in everyday life and when playing sports and not only. In addition to the main function of the watch, it includes the functions of a fitness tracker that tracks your physical activity and even smartphone functions with the ability to make calls, transfer data and even access the Internet.

A little earlier, in articles about fitness trackers, we already began to cover such a current topic as devices that monitor your physical activity indicators. In the article, respectively, we presented the 20 most popular fitness bracelets with their descriptions. The main purpose of these two articles was to show that even if you take 20 different bracelets from different manufacturers, you will not find a significant difference between them. This brings us to the fact that when considering the topic of smart watches, we will take into account previous experience and within the framework of one article we will analyze exactly 10 representatives of this category of wearable gadgets, no more and no less. This number will allow us to compile a certain sample, the characteristics of which will make it possible to fully evaluate what the market of so-called smart watches offers us.

What is a smart watch

As you might guess, both watches and bracelets are worn on the hand, namely on the wrist. If we are talking about electronic fitness gadgets, then what is the difference between smart watches and fitness bracelets? First of all, from the point of view of assessing the appearance, this is an electronic dial (also known as a display), which most bracelets do not have. Secondly, this is a functional component, which in smart watches has much broader capabilities, which are worth dwelling on in more detail. Since over time, smartwatches have grown into an independent market segment, which became possible thanks to their technical progress, they have moved from auxiliary devices for a smartphone, tablet or PC, into the category of full-fledged operating system carriers with an almost complete set of similar functions, applications and hardware.

Built-in fitness trackers. Most smartwatches have a pedometer, heart rate monitor, sleep tracker, altimeter, accelerometer, barometer, compass, GPS, and so on. And synchronization with fitness applications allows you to record the data received.

Software. The set of installed programs and built-in capabilities often duplicates the smartphone platform and includes a browser, mail, messages, gallery, voice recorder, calendar, calculator, alarm clock, notebook, music player and even a telephone.

Computing capabilities. To perform the tasks assigned to them, smartwatches are often equipped with a processor (with 1, 2 or 4 cores), RAM and a hard drive. As well as means of output (display) and transmission (Wi-Fi, Bluetooth) of information.

FACT. It is also important to note that smartwatches do not necessarily have to be equipped with a processor, RAM or operating system. Among the list of watches “charged” with such filling, you will find no less “fat” representatives, such as the Basis Peak, which do not have a processor, RAM or operating system, but are not inferior in functionality to competitors “stuffed” with the above-mentioned bells and whistles.

How smart watches work

In full accordance with the previous paragraph, the presence of specific functions is dictated by the presence of specific sensors. Applications that are part of the software, as well as computing power, do not need to be described, but the principle of operation of the sensors that help you in the training process is perhaps worth describing.

Heart rate monitor is based on data on recording the potential difference, which the device reads using electrodes placed on the inside of the bracelet or the watch case itself. The received data is interpreted by the computer into information on the display.

Accelerometer, how a spatial positioning device receives data on the movement of a counterweight placed between two boards, and thus converts the received data into one or another motor activity.

Gyroscope– a kind of analogue of an accelerometer, which is a device with a free axis that maintains a constant position during any movement of the device in three-dimensional space. This allows you to obtain data with significantly greater accuracy.

Altimeter, also known as an altimeter, is based either on the indicators of the built-in GPS module, or by interpreting data on the pressure difference obtained from the barometer, which in the watch is a sealed metal flask with thin and elastic walls.

Magnetometer– a sensitive sensor, the task of which, by determining the direction of the earth’s magnetic field at a certain point in space, is to point to the north pole, in other words, this is the basis of an electronic compass.

Hygrometer in electronic devices it is a resistive humidity sensor. The sensor has two electrodes coated with a material characterized by low resistance, which changes depending on humidity, which allows data to be recorded.

Pedometer, also known as a pedometer, records the vibrations of each step while walking and transmits them to a sensor, which converts the vibrations into an electrical impulse, interpreted by the computer before the data is displayed on the display.

Proximity sensor is an infrared diode and infrared radiation detector. The diode produces radiation, and the detector tries to catch its reflection. The moment the detector catches a reflection, the sensor is triggered.

Light sensor consists of a photodiode and a relay. The photodiode analyzes the radiation of the visible part of the spectrum (the proportion of white, red, green and blue light), and the relay, based on the data received, adjusts the brightness of the screen.

Thermometer is based on the principle of using a thermocouple - two conductors of different materials connected at one end and forming part of a module that uses the thermoelectric effect to measure temperature.

How to set up a smart watch

Since this device is a full-fledged and independent computer, with a screen and an operating system, setting it up will be no more difficult than setting up your smartphone when you first launch it. If necessary, you will need to register via E-mail on the manufacturer's website or in various applications that you want to use. Enter your data for fitness programs, which will carry out calculations based on your anthropometric data and that’s probably all. You can set any custom parameters through the settings menu, where you can also synchronize your smartwatch with a smartphone, tablet or PC via Wi-Fi or Bluetooth.

How to use a smart watch

As for use, as we mentioned earlier in the article about fitness trackers, you first need to pay attention to dust and moisture protection standards in order to understand what operating conditions should be adhered to so that the device does not fail. Also on the temperature range of application and impact resistance. It is advisable to check with the seller for the presence of a warranty card in the kit and the terms for returning the goods in the event of a factory breakdown, as well as to find out about the presence of certified service centers in your city in case the defect is caused by the fault of the user. After purchase, be sure to read the operating instructions and follow the manufacturer's recommendations.

Conclusion

Our short excursion into the world of smart watches gave us, first of all, the opportunity to answer the following questions: why are smart watches needed, how do they work, what functions do they perform and how to use them. The question of how to choose a smart watch, be that as it may, rests entirely on your shoulders, since each person in each individual case considers one, another or third parameters important for himself. For some it will be computing power, for others it will be software, for others it will be a wide range of built-in sensors. Hence the conclusion - the choice of device should be based on your goals. The goals will show which parameters are considered the most important in your case, and based on the parameters you can select the gadget you need, if you need one.

In addition to the standard time display function, “smart watches” or “smart watches” (from the English “smart watch”) are primarily positioned as an assistant or an additional screen/remote control for a smartphone.

“Smart watches can take on some of the functions of a smartphone, and advanced models can even completely replace it. Let's take a closer look at the characteristics that should be taken into account when choosing a smartwatch for purchase.

What can smart watches do?

The capabilities that smart watches offer us vary significantly depending on their equipment. Conventionally, we can distinguish three sets of smart watch configurations:

1. Basic option offers display of the current time/date (main function), notification of incoming calls, SMS and e-mail messages via sound or vibration. There is no function for displaying message text on the screen in such models. Also in the basic version, the watch user will be able to control the smartphone, for example, put it into sleep mode.
2. Middle option. Such modifications display information not only about received SMS and e-mail messages, but also the information that the smartphone received from installed programs. These watches provide installation of additional applications, and they are also equipped with monochrome or color screens that allow you to play audio and video content.
3. Advanced option. This is a combined option that combines the previous two, plus the ability to search for information on the Internet and work with applications. Such models mainly have a color touch screen, and in terms of their versatility they are practically on the same level as smartphones.

Features supported by smartwatches

The variety of features in different smartwatch models is impressive. The most common of them:

• Supports voice commands;
• Stopwatch;
• Timer;
• Compass;
• A smart alarm clock that goes off at certain moments of sleep, making getting out of a sleepy state more comfortable;
• Monitoring sleep, physical activity and calorie consumption;
• Sensors: accelerometer, heart rate monitor, gyroscope, thermometer, altimeter, light level measurements;
• Multimedia functions – video and photo camera, microphone, FM radio, speaker, headphone jacks.

Unique smartwatch features

Some smartwatch models support special features that other devices do not have.

For example, the LG Watch Urbane LTE gadget has a Push-to-talk (PTT) function, which allows you to communicate with other devices on the same mobile frequency, or, in other words, use them as a walkie-talkie, maintaining contact with several subscribers at the same time.

And the Haier Smartwatch model has a small SOS button on the right side, which sends a text notification to three recipients in case of problems.

Compatibility of smartwatches with other devices

Direct connection plays a huge role in smartwatches. In most cases, smartwatches work quite well with smartphones that support the Android operating system. These are devices such as Motorola Moto 360, Sony Smartwatch 3, ASUS ZenWatch, Pebble Time and others.

As for the iOS operating system, it can be supported by such family members as Apple Watch and Pebble Time. However, in the case of the latter, the functionality becomes a little limited.

Some smartwatches, such as the Samsung Gear S, operate on a specially developed Tizen operating system, which provides its own special capabilities for the watch and its synchronization with smartphones.

Compatibility of smartwatches with mobile platforms

When buying a smart watch, you should pay attention to the possibility of its compatibility with the operating systems of your existing smartphone - Android, iOS, Windows Phone. Basically, when manufacturers indicate a supported OS, they mean its highest version, which will definitely be supported in this gadget. That is, it is assumed that these devices will be “friendly” with all newer versions of mobile platforms.

Recently, there has been a popular trend among smartwatch manufacturers to produce models that can support multi-platform functionality.

Smartwatch case material

The classic version of the material used is, of course, metal. Recently, stainless steel has been the most commonly used material in smartwatches. This material is quite durable and relatively inexpensive raw material. Although it is worth noting that over time, the stainless steel case begins to scratch, which leads to a deterioration in the appearance of the watch. But due to the optimal price/quality balance, this material is used for the manufacture of cases more often than others. Huawei Watch, Asus ZenWatch 2, LG Watch Urbane, LG G Watch R, New Moto 360 - all these models are based on stainless steel.

Quite often, plastic is used to make “smart watches” as a light and cheap raw material, which, of course, is an order of magnitude inferior to stainless steel in such important qualities as strength and durability.

The cases of expensive models are made of polycarbonate, a very durable plastic. This category includes Moto 360 Sport, Sony SmartWatch 3 (plastic version).

Straps for smart watches

The owner of a smartwatch has the opportunity to change straps to suit different styles and colors of clothing. A variety of modern materials are used to make straps.

• Plastic strap- hypoallergenic, moisture resistant and pleasant to the touch. At the same time, the quality of service has a weak indicator.
• Silicone strap in most cases it has the same set of pros and cons as plastic.
• Metal strap durable and resistant to external irritants. Among the disadvantages is that the metal is heavy in weight and has high thermal conductivity, and therefore can cause unpleasant sensations in winter.
• Rubber strap combines inexpensive and durable material that can be easily given the desired color. This strap fits the wrist well, is resistant to moisture and has low thermal conductivity. Among the disadvantages, it is worth noting that these straps can cause an allergic reaction such as redness and rash.
• Leather belt- soft, elegant, but quite expensive material. Used in the manufacture of branded models.

Smart watches can be equipped with either replaceable or non-replaceable straps. Models that use replaceable straps include the same Huawei Watch, LG Watch Urbane, LG G Watch R, New Moto 360, Asus ZenWatch 2. In turn, Moto 360 Sport and Samsung Gear Live do not provide replaceable straps.

Screen matrix for smart watches

LCD— the liquid crystal version of the screen matrix in “smart watches” is most often found due to its relatively low cost and acceptable color rendering quality. There are several modifications of LCD technology: IPS, TN+film, Super LCD. The disadvantage of such a screen is the requirement for internal backlighting and the inability to read in bright sunlight. LCD display is used in gadgets such as Moto 360 Sport, Sony SmartWatch 3 and others.

More and more modern gadgets are equipped with screens that are based on OLED- technologies based on organic light-emitting diodes, which effectively emit light when electric current passes through it. OLED technology combines greater brightness and color contrast than an LCD screen. Such a display does not need backlighting and consumes little energy. In addition, the OLED display is much thinner and weighs much lighter than an LCD screen. True, on the other hand, such a screen is more expensive, and at the same time less durable than a liquid crystal one.

AMOLED and SUPER AMOLED technologies offer simply fantastic colors and deep contrast conveyed by the gadget’s screen. These screens are perfect for reading in the sun. At the same time, the quality of color rendering of white and black colors in this technology is very far from ideal. Models with AMOLED screens are Huawei Watch, Asus ZenWatch 2, Haier Smartwatch.

P-OLED screens are new-fangled bendable screens that ergonomically follow the contours of the wrist, do not catch on clothes at the corners and do not get in the way. The curved screen allows for comfortable reading in any position. Representatives of smartwatches equipped with P-OLED screens include the LG Watch Urbane and LG G Watch models.

E-ink– an electronic paper screen, the characteristics of which allow you to display only text and graphic information exclusively in monochrome mode without the ability to play video. Yes, such screens cannot boast of being colorful, but the advantages of this technology are super-economical energy consumption and excellent readability in the sun.

Mirasol- displays have all the same advantages as E-ink, while being able to display images in color.

View of the glass screen of a smartwatch

The glass options used in smartwatch devices are different and depend on the cost of the watch. Ordinary plastic does not break, but quickly loses its decent appearance due to its susceptibility to scratches. Inexpensive, mostly sports, smartwatch models are equipped with plastic screens.

In branded modifications, the screen is equipped with mineral (Cristal Glass) or sapphire (Sapphire Class) coatings, which are not scratched, retain their appearance for a long time, but are not resistant to mechanical damage, that is, they often break.

The advantages of all types of glass are combined with combined glass, for example, with the Gorilla Glass marking, the glass characteristics of which include scratch resistance along with impact resistance.

Smartwatch interfaces

Common wireless interfaces in watches are Bluetooth(up to 10 m) and WiFi. The most popular versions are Bluetooth 4.0 and 4.1, which are capable of providing a reliable connection with a mobile phone, tablet and desktop with minimal energy consumption in both transmitting and receiving gadgets. Wi-Fi technology is not so universal, since its coverage area is limited and “tied” to certain access points in public or private places.

A less common data transmission technology is NFC. To pair, you need to touch the two devices to each other. The maximum distance between devices should not exceed 10 cm. NFC is similar to Bluetooth, but requires a minimum amount of energy and provides almost instantaneous connection speed. The fly in the ointment is the transmission speed, since in this version it is lower, and the cost of a watch with such a port immediately changes towards becoming more expensive.

Another data transfer standard is ANT+, allowing you to connect smart watches and sports sensors with each other at a distance of up to 30 m. Widely used in sports trackers and medical gadgets. Plus, working via the ANT+ port requires 70% less energy than via Bluetooth. The disadvantage of this technology is that it shares the same frequency range with Bluetooth, so when two ports operate simultaneously, loss of information packets may occur.

Wired interfaces that are built into smart watches and used for charging and data transfer include standard USB, mini-USB and micro-USB ports.

Smartwatch batteries

Smart watches mainly have two types of batteries – Li-Ion and Li-Pol. Li-Pol is a more advanced battery model, the distinctive feature of which is its compactness and lightness, which is especially important for devices that are small in size. The battery charge can vary from 300 to 420 mAh. For charging, standard micro-USB, USB ports or the original manufacturer's connector are used, which will require an additional proprietary cable or cradle (frame with connectors).

In most cases, watches are equipped with non-removable batteries, which allows you to expand their capacity. To replace such a battery, you will have to contact a specialist. There are also removable batteries with low capacity, which are mainly used in watches without a screen or models with an E-ink display.

Smartwatch battery life

The amount of time a smartwatch can last on a single charge varies depending on its hardware, such as its screen features and how much built-in functionality you use.

The number of hours of battery life should not be less than 24 hours. The optimal choice would be to choose a gadget that will need to be recharged once every 1-2 weeks.

"Smart watch" with a SIM card as a replacement for a smartphone

A revolutionary solution for many smartphone users is to replace a bulky “shovel-shaped” mobile gadget with a compact “smart watch” with a built-in SIM card. This is quite convenient, because now you don’t need to look for your phone in your bag or take it out of your pocket to make calls or send SMS. A smart watch is always with you, always on your hand, so it is more difficult to lose it.

Smart watches can support three types of SIM cards:

• mini SIM card– a regular SIM card measuring 25 by 15 mm;
• microSIM card– compact SIM card measuring 15 by 12 mm;
• nanoSIM card- the smallest SIM card measuring 12.3 by 8.8 mm, which is used in the most modern new devices.

Types and classes of protection for smart watches

An important characteristic is the degree of protection. There are 3 types of protection:

• from dust/moisture;
• from penetration of moisture into the body;
• from blows.

Dust/moisture protection is marked as IPXX, where the first X is the level of protection against dust, the second X is against moisture.

• IP55 class– a housing protected from dust, as well as from jets and splashes of water in any direction. Immersion in water is not provided;
• IP57 class– a housing protected from dust, from jets and splashes of water in any direction, as well as from contact with sea waves. Diving to sea depths up to 1 m is possible;
• Class IP67 – completely dust-proof housing, protection from jets and splashes of water in any direction, protection from sea waves. Diving to sea depths up to 1 m is possible;
• IP68 class– dust- and waterproof housing. Diving to sea depths of more than 1 m is possible.

Protection of the housing from moisture penetration into the body of a “smart watch” is measured in the number of atmospheres of pressure and also implies division into several classes:

Class WR10-WR20 (1-2 atm.)– the weakest protection (protects from rain and when washing hands). This protection class is the most common;

Class WR30 (3 atm.)– protection when taking a shower and while washing the car;

Class WR50-WR60 (6 atm.)– direct work with watches in water conditions. The most optimal choice for the buyer;

Class WR100-WR150 (10-15 atm.)– for people who engage in swimming and diving;

Class WR200 (20 atm.) and higher – professional protection class, used when scuba diving.

Information about water resistance is usually written on the watch case.

Impact protection is ensured by equipping the smartwatch case with a special shockproof device. Such “smart watches” will be useful for athletes and outdoor enthusiasts, but they are much more expensive than ordinary models.

What to consider before buying a smartwatch

• Watch screen diagonal can range from 0.5 to 2 inches and makes a big difference. A larger diagonal size provides greater ease of use of the watch, but it should be taken into account that its energy consumption increases along with the price.
• “Smart watches” should not be bought without trying them on. The comfort of “sitting” on the hand is an important point that should be taken into account when buying a “smart watch”. It will be better if the watch strap is adjustable. If the strap is not adjustable, then the model should be selected with special attention and care.
• Detachable strap– an undoubted advantage of the chosen smartwatch model. If the strap becomes worn or accidentally damaged, it can be easily replaced.
• Smart watch brand. When choosing a smart watch, you should pay attention to well-known, trusted brands of manufacturers who have already proven the quality of their products. Such models guarantee wear resistance, long and trouble-free service.
