Huawei Watch D2

Blood pressure monitor watch

Smart watches from Huawei are not cheap, but they fully pay for their price with advanced features and extended functionality. The model is primarily designed for thorough health monitoring. This is not an ordinary gadget for every day to measure steps taken and display time and not just a stylish accessory on the wrist, but, one might say, a useful medical assistant. Accordingly, the device is unlikely to be relevant for teenagers and young people, but it will definitely be useful for people over 30 and older generations.

The main feature is the function of measuring blood pressure, and these are not dubious readings of sensors, but real measurements, like a tonometer. It is not for nothing that the watch is certified as a medical device in China and Europe. To measure pressure, there is a cuff under the strap, which is inflated using a mini-pump. You also need to take a special pose with your hand at heart level - all the details and rules are described in the instructions and indicated on the screen. The watch takes measurements in 30 seconds and, as practice has shown, gives fairly accurate values of systolic and diastolic pressure. Discrepancies with the readings of medical tonometers are insignificant, so if the gadget signals low or high pressure, it is better not to ignore it and consult a doctor. In addition, the watch is able to measure blood pressure around the clock, which is especially important for hypertensive and hypotensive patients. During the day, they simply periodically remind you of the need to take measurements, and at night they do it automatically, since the sleeping position of a person provides for the correct position of the hand at heart level. By the way, the cuff inflates smoothly and quietly, so the risk of waking up from this is minimal.

Features of operation

However, the tonometer model has some features that affect operation. Firstly, for accurate measurements, it is necessary to select the correct strap length, otherwise the device will not work correctly. Fortunately, the package includes two straps for wrists of different sizes. Secondly, although the manufacturer declares IP68 water protection, it cannot be called full-fledged. The watch can withstand splashes and rain, is not afraid of sweat during intense workouts, but due to the design features, it cannot be immersed in water or used for swimming. Otherwise, the design and equipment of the model are thought out, and it does not look like a “black sheep” against the background of ordinary devices. Perhaps the thickness of the strap and case is slightly larger, which does not affect the convenience of daily use.

Health monitoring and long-term autonomy

Huawei Watch D2 can measure not only blood pressure, but also blood oxygen levels, skin temperature, do an ECG, track sleep duration and stress levels. In general, the user receives fairly detailed and accurate information about their health. In addition, there is support for more than 80 sports modes and activity control. NFC for contactless payment for purchases and services does not work in all countries. But the microphone and speaker allow you to make calls through a smartphone connected via Bluetooth.

Despite its multifunctionality, the capacious 524 mAh battery provides long battery life. With normal use with several pressure measurements per day, one charge lasts up to 6 days, which is quite a good indicator for a watch with such complex mechanisms. But keep in mind that round-the-clock blood pressure monitoring significantly reduces this time - the gadget will have to be charged almost daily.
