TOP 10 smart watches with blood pressure measurement in 2021. Review of the best models

Not all models have it. The problem is that opinions about this function vary - there is no doubt about its necessity, but not every smartwatch with blood pressure measurement takes measurements correctly. And even those manufacturers who were able to achieve high accuracy do not recommend using their devices for medical purposes. The medical community agrees with this. The rating of smart watches with a blood pressure monitor will tell you about the most interesting models on the market in the first half of 2021.

How does a watch with a blood pressure monitor measure blood pressure?

The principle of measuring blood pressure with a smart watch is significantly different from measuring it with a conventional tonometer with an inflatable cuff. The watch determines pressure by mathematical analysis of information received from sensors. This is the speed of propagation of the pulse wave, its length, pulse frequency, ECG, etc. After receiving this data, they are transferred to a special mobile application, which automatically analyzes the information received and displays the finished result on the screen of a smartphone or watch.

This method was invented in the middle of the last century by the French scientist Etienne Jules Marey, which is why it was called the “Marey Method”. It is also now called photoplethysmographic blood pressure measurement. But, unfortunately, this method of measurement cannot provide high accuracy and cannot replace the “classical” one.

To obtain more or less accurate values ​​using photoplethysmographic measurements, it is advisable to follow a number of recommendations:

• Before starting the measurement, indicate your physiological data: gender, height, weight and date of birth. This data will allow the software to calculate the data more accurately.
• During the measurement process, try not to move, talk or laugh.
• It is best to take the measurement while sitting, holding your hand at heart level.
• Before measuring, exclude any pacemakers from your diet (tea, coffee, etc.)
• For reliability, repeat the measurement several times.

GSMIN WR11 2021

Sports cardio bracelet with ECG and tonometer

GSMIN WR11 (2020) belongs to sports bracelets that are convenient to wear in the gym or during outdoor activities. It will help you independently evaluate the effectiveness of your training and analyze how accurately the load on your body is calculated.

A special application on the phone called Mecare will allow you to view all collected data, statistics and provide an analysis of the obtained indicators.

When measuring blood pressure, the bracelet provides the following information:

1. Heart rate
2. User's AD
3. General fatigue rating

The device's battery capacity of 130 mAh allows it to work for up to 5-7 days before the next charge. There is also IP67 protection against water and dust, but you cannot swim with the device on your hand.

You can buy a fitness bracelet with ECG and pressure GSMIN WR11 for $76, or 5900 RUR. rub.

How accurate is the watch's blood pressure readings?

Unfortunately, there are no official statistics on the accuracy of blood pressure determination. According to unofficial data, the average error is within 20% or approximately 10 - 20 mmHg. But, as we have seen from experience, the same device, when measured by different users, can show different errors. Perhaps this is influenced by various physiological characteristics, for example, the depth of the blood vessels, skin color, etc.

Now that we've sorted out the theory, let's move on to the watch itself. In this rating, we tried to collect only the best models of watches with pressure measurement based on reviews on the Internet and our own experience of use. But it is worth clarifying that almost all of these devices do not claim to be a medical device, so the data obtained with their help can be used for informational purposes only.

Comparison table with prices and characteristics

For your convenience, we have compiled a table with the main characteristics and prices of the best fitness bracelets of 2020-2021 capable of measuring blood pressure and pulse, which were included in our rating.

Omron HeartGuide

Let's start with Omron HeartGuide, which we already mentioned at the beginning. This is a unique device of its kind, essentially combining a smart watch and a regular blood pressure monitor. During the design period, Omron received more than 50 technology patents related to the miniaturization of all major components (pumps, valves, etc.).

The principle of measuring pressure is practically no different from measuring it with a conventional tonometer with an inflatable cuff, so the results are as accurate as possible. There are air cylinders inside the strap that are inflated during the measurement process. According to the manufacturer, the cuff will withstand up to 30,000 inflations. The device's memory stores the last 100 measurements, and the data is also synchronized with the Omron Connect mobile app.

In addition to measuring blood pressure and heart rate, HeartGuide can count steps taken, distance and calories, monitor sleep and notify about incoming calls and messages. Information is displayed on a very simple and small LCD screen, and the battery life is from 2 to 4 days.

This is where the advantages of this device end. Firstly, for now HeartGuide only works with iOS devices, although there are plans to also support Android devices. Secondly, Omron HeartGuide is not currently sold outside the US - there is no license for it. Thirdly, in the states they want 499 US dollars for them, which is a bit expensive for a hybrid of a fitness bracelet and a blood pressure monitor, although accurate.

Key Features of HeartGuide

• LCD display with transflective memory.
• Lithium-ion battery.
• Autonomy: 2 - 4 days of use.
• Compatibility: iOS.
• Connection: Bluetooth 4.0.
• Features: Pulse measurement, blood pressure, counting steps, calories and distance, notifications of calls and messages, sleep monitoring.
• Weight: 115 g.
• Dimensions: diameter 48 mm, thickness 14 mm.
• Price: From 499 US dollars.

Differences between smart watches and fitness bracelets

Stay up to date! The main differences between smart watches and fitness bracelets are:

1. The operating system makes the gadget smart. Fitness bracelets do not have it ; the work is ensured by a special microcode.
2. Most models of fitness bracelets do not have GPS. Data on trajectory, speed and distance are provided via synchronization with a smartphone. For example, taking your phone with you when jogging is not always convenient. In this case, smart watches come to the rescue.
3. Autonomous work. The large screen and operating system in smart watches require a lot of energy. Due to its small dimensions, the battery capacity is not very high. Therefore, without recharging, smart watches work for up to three days, rarely – a week in energy-saving mode. Fitness bracelets can last from a week to a month and a half, depending on the model.
4. Price. Fitness bracelets are much cheaper than smartwatches.

ASUS VivoWatch BP

This watch no longer has an inflatable cuff and a system of two medical-grade electrocardiographic sensors and a photoplethysmographic sensor is responsible for the accuracy of blood pressure measurements. To measure pressure, just place your finger on the sensor on the front of the watch for 20 seconds.

Right out of the box, accuracy may not be the highest. But, after calibration, it is within 5%, which is quite acceptable for a non-medical device. In addition to pressure, the watch can measure heart rate, assess sleep quality, track several exercise modes, notify about calls and messages, count steps, calories, and distance. There is an alarm clock and several dial options.

VivoWatch BP is equipped with a 1.26-inch transflective screen and a battery that provides up to 14 days of battery life. They ask for about 200 US dollars for the watch.

Healthband Health Watch Pro No. 5

Healthband Health Watch Pro No. 5 Photo: Healthband.net

This 2021 model from the Russian company Healthband can be called a “professional cardio watch.” The sensors and electrodes, hidden in their stylish steel case, are “written off” from parts used in specialized medical equipment and are very sensitive. The big advantage of such a watch is that even without being tied to a smartphone, it does an excellent job of “status tracking” functions.

In terms of pressure measurement accuracy, today this model ranks first in the rating of products from this manufacturer. But you need to keep in mind: before you start using Health Watch Pro No. 5, the watch needs to be “calibrated” so that it remembers the starting indicators and gives current measurements taking into account the error. By the way, the gadget not only monitors the pressure of the “owner”, but also measures his body temperature, blood oxygen level, takes and even deciphers an ECG. It also counts the distance traveled, calories burned per day, monitors sleep quality, and so on - in a word, it can do everything that other smart fitness watches can do.

The universal gadget Samsung Galaxy Watch 3, which is available in two versions (in steel and titanium cases). The “skill” of measuring pressure by the manufacturer has been perfected. Although the watch cannot be called a professional blood pressure monitor (by the way, the technical data sheet for the device strongly recommends that its readings should not be considered sufficient to make a diagnosis), according to user reviews, the Samsung Galaxy Watch 3 calculates blood pressure quite accurately. The maximum error is 5-7 units. It’s no wonder that this watch is the company’s flagship product today. True, it is not recommended to measure blood pressure with them on the go; to obtain the most accurate data, sit on a chair, place your hand on the table so that your wrist is in line with your heart and go ahead! This smartwatch will not let you down. They have a very large range of convenient functions. For example, in order to respond to a message received on the phone, the device only needs Wi-Fi. The watch connects to the smartphone automatically, including via 4G.

One of the most budget smartwatches with good functionality. They can work up to two weeks without recharging. The case is strong, there is an oxygen sensor and GPS. Like all models from the Bip line, this one can be called the best for your money. The display is large enough, but the brightness after AMOLED may not be enough, as well as the always-on screen function. But for the amount of 5,000 rubles, IPS is the optimal solution. The menu is in Russian. The case is protected from water, so there is no need to remove the watch when washing your hands, taking a shower, or swimming in the lake. There are more than 60 sports modes, a clear pedometer, breathing exercises, smartphone camera control, and a timer. The SpO2 sensor works correctly and the accuracy is good.

The best smartwatch with ECG measurement for those who have an Apple smartphone.

Inexpensive by Garmin standards, smartwatches for sports and more. The manufacturer has equipped the model with the ability to determine saturation, and the results are close to those shown by the medical device pulse oximeter. Reviews note the convenience of the application: it has many different features and a large selection of watch faces. The battery life is quite comfortable.

There may be problems with repairs - in Russia there is no Garmin service department, so even for money it is not easy to repair a broken watch.

Advantages and disadvantages

• Beautiful design
• Compact size
• Functional application
• Large selection of watchfaces

• Expensive branded accessories
• Small screen
• Inconvenient navigation in the watch interface

Smart watches that can be called the best in terms of battery life. Without recharging, they can last a week, and at full load they can withstand at least two days.

Reviews are satisfied with the brightness and size of the screen, the wide selection of dials, and the ability to answer calls. There is no payment via NFC, and this is disappointing. The model is perfect for both those who are actively involved in sports and those who need a smart companion watch with saturation tracking function.

• Large bright display
• Long battery life

• No NFC module for payment
