What is a smartwatch?

To understand what a smartwatch is – or “smart watch” if we translate it into Portuguese – we need to forget that outdated concept that a watch is used to show the time. A smartwatch is an extension of your smartphone phone on your wrist. With it, you stay connected all the time, without even having to take your cell phone in hand.

You can see the notifications from your social networks. Use it as a GPS. It is still your best friend controlling your heartbeat, alerting your sedentary lifestyle, and being a great ally in the practice of physical activities.

All this through integration via Bluetooth. Many functions you find on your phone, you can access now with a few taps on your watch. But is it worth buying one?

What are the advantages and disadvantages of having a smartwatch?

The truth is that with the various functions that it offers, you will realize that your cell phone does not always need to be in your hands.

Some models allow bracelet change and screen customization through applications.

You will no longer miss an important call because it was in your pocket or purse. It won’t take long to answer that urgent message, and you can schedule an appointment on your digital agenda without needing anything other than your watch.

The advantages are numerous, and indeed, this practicality is the main one. Also, a smartwatch is a very modern gadget that brings sophistication to any style. They are very light devices and do not bother you at all daily. Once you get used to one of these, you no longer want to take it off.

Some models allow bracelet change and screen customization through applications. The display can vary between digital or analog display, can have a different “face” whenever you want.

It is still excellent for you to take care of your health. Some smartwatches emit a sedentary alert and even count how many steps you have taken in a single day, encouraging you to walk more.

It is possible to program a diet, count calories, monitor heart rate, check blood pressure, control distance in a run or ride, among other incredible functions that only stimulate an increasingly healthy life.

And you can still do it all by listening to your favorite music without relying on your cell phone. Regarding the disadvantages, we can point out that a conventional watch ends up demanding less from you. Just put it on your wrist, and it did – of course, it also offers nothing but showing the time.

Battery life can be considered as a negative point. Many people who use it all day may have to recharge some models every night.

Some people also complain that the devices do not work autonomously, that is, they need the cell phone nearby for connectivity via bluetooth.Benefits

  • Offers more practicality as an extension of the cell phone on the user’s wrist
  • Can answer and make calls and has connectivity to various applications
  • Mobile notifications viewer panel
  • Light and modern appliances that bring style and comfort to everyday life
  • Functions encourage a healthier life


  • Short battery life due to functions and digital panel
  • It may not be very autonomous, as it requires the cell phone to be nearby for connection via bluetooth

What is the difference between a smartwatch and smartband?

A smartband, or smart bracelet, is a gadget similar to a smartwatch in some functions, but it also has some differences that we will highlight here. It is an option for those looking for a watch more linked to health and well-being. It ends up being very limited and is indicated for those looking for a device to monitor their bodily functions, such as heartbeat and sleep, calorie counting, or other things more related to health.
It is also cheaper because it offers fewer functions. A smartwatch ends up being a real extension of your cell phone on your wrist. Being able to access other applications, galleries, games, among others.

Check out the main differences through this comparative table:

CostHighest valueLowest value
FunctionalityGadget with high functionality, being an extension on the cell phone on the wristFunctions related to health and well-being
ConnectivityIt may be able to connect to the internet and run some applications such as WhatsApp, Facebook and TwitterUsually connects only with other devices like computers or smartphones
Other featuresCan take pictures and access some gamesLimitation of functions

How much does a smartwatch cost?

The models of major brands can easily vary between R $ 1,000 and R $ 4,000. Some models recently launched by the famous American brand can be sold for up to R $ 9,000 in Brazil. But this investment is not necessary to have a useful smartwatch. The Chinese brand Xiaomi offers excellent options for around R $ 600. It is also possible to find even cheaper models, which cost R $ 269.90.

It is essential to keep in mind that the price is associated with the functions that these gadgets offer, in addition to the brand. Therefore, a much cheaper model cannot fulfill the same functions and have the same compatibility as the more expensive ones.

Where to buy a smartwatch?

Due to the popularity of these watches, it is not difficult to find a model. You can shop at computer stores specializing in electronics or department stores like Havan and Lojas Americanas. Although you can find it in physical stores, it is on the internet that you will find more variety and also the best prices and offers.

All models mentioned in the ranking are available on the Amazon website. You may also find some of them on the website at Submarino or Magazine Luiza.

Purchasing criteria: Factors for comparing smartwatch models

Buying an electronic device is always time for a lot of research. After all, the user does not want to risk investing their money in lousy equipment.

For your purchase to be a success and you will not regret it, we will bring you some purchase criteria that can be decisive in evaluating the products even after reading this complete guide.

Reflecting on some points is very important for you to be delighted when the product arrives at your home:

  • Existing functions
  • Battery life
  • Display quality
  • Touch screen
  • Product evaluation
  • Wi-Fi
  • Bracelet

Existing functions

The functionality without a doubt is the most crucial criterion. After all, understanding what the smartwatch offers is essential for you to know exactly what to expect from your buying product.

So, to start, reflect: What do you want a smartwatch for? Which functions we have discussed throughout this guide are essential for you? Are you going to use for sports or want a watch that connects intelligently with various apps?

These answers eliminate some models from the ranking and give a more assertive direction for your purchase.

After all, if you are a born sportsman, you can love the Samsung model. Or if you are not thinking of using it for that purpose, who knows the first one is not what you are looking for. Think about the reasons why you buy a smartwatch and buy well.

Battery life

Some models only last for one day, requiring you to charge the battery every night to use the next day. Others can last up to more than 30 days, as the first in the ranking. Is this important to you, or does it matter a lot?

Because there is no use investing in a smartwatch and walking around with it discharged. You won’t even be able to see the time. Then analyze the battery capacity of the models and reflect on which is best for your reality.

Display quality

A digital display is a marvel. But it would help if you took some precautions before finalizing your choice and making your purchase.

First, regarding visibility. Some models may have some problems outdoors, with a lot of clarity, for example. Others can be bad to see at night.

So try to pay attention to the description. When the display is OLED, it is an indication that it is very good, like the Apple model.

Also, notice the quality of resistance of these screens. Nobody wants to have the screen broken or scratched with a fall, or if they hit their arm on the wall, for example. If they are glass gorillas, they are generally more resistant to scratches and cracks.

Touch screen

Be careful. Not all smartwatches are touchscreen. This is not a problem, but some users are disappointed when they receive the product, and the screen is not so. So it is essential to read the description carefully.

Some models have control via buttons external to the device, which may or may not be what you are looking for. The sixth model in the selection is cheaper and does not have this feature, so be careful if the touchscreen is essential for you.

Product rating

We search for the best-rated products for you. Trying to introduce you to those who stay between 3 and 5 stars.

The users themselves make this assessment. No one better to say that the product is excellent than the one you use. Perhaps this recommendation can help you with your choice.


Bluetooth integration is a must-have for a smartwatch. But stay tuned, as not all models have a wi-fi connection.

Not that it is essential, but it is worth mentioning this detail if it is relevant to you. The wi-fi connection allows you to access more functions.

It works the same on a smartphone through the device settings to connect to the internet on a smartwatch. The first four models have this connection, for example.


Regarding the bracelets, three things can be significant: the bracelet’s length, if you can change them, and if they are of good, comfortable, and resistant material.

Check the measurements of the bracelet and compare it with any other watch you have at home. See if centimeters are right for you. You can even draw the measures on a piece of paper with a ruler and wrap them around your wrist.

Also, see the possibility of changing the bracelet. A versatile model that you can buy other spare straps and change from time to time can be attractive if you want to watch a different face.

And even buy bracelets of different material. That can make your smartwatch more sporty or casual. You can find options in leather, and others very interesting on the internet for some of these models.

About the quality, also notice in the description. The mentioned models are made of silicone, are resistant, flexible and offer comfort.
