Huawei Watch D Review : A Watch That Can Save Your Life | Tech Reviews
Huawei continues to reaffirm its good path of exploration, and the watches have consolidated what we have already been saying: that impediments and vetoes have only promoted more open solutions from the company. After the successful GT and GT Pro series , the brand presented a watch capable of reading blood pressure at the last MWC. We’ve had it put to the test and we’re ready to answer the classic question: Is it worth going for the Huawei Watch D?

Huawei Watch D: this is what you should know
The first version. I want to start with this because I don’t want to lose the context of this review from the point of innovation. It’s Huawei’s first attempt to replicate a pressure measurement system on that scale, and there are still steps to be taken in portability and design so that the equipment can seamlessly fit into a more commercial sector in the field of smart watches.
This serves as an argument to explain, in a certain way, the excessive size of the Watch D compared to other devices in the wearables market . We are talking about 40 grams and a prominent chassis on any wrist, including mine. It is wide, but it is on the border of acceptance as long as the user has more, let’s say, “contact surface”.
The robust rectangle displays, on the right side, two interaction buttons: one called HOME and the other labeled HEALTH. On the inside, the base integrates Huawei’s sensor array for parameter measurement and the wireless charging system.
What I do find curious is the IP certification of the equipment. Although we have IP68 to protect the integrity of the watch, the straps do not have that protection against dust and water. If you are going to bathe, take off your watch.
The straps are another matter. Huawei’s system includes two different games, graduated according to the size of the wrist, assigning a specific measurement for the size of the contact area and giving the user a wide margin to find the right grip with which we can start the mechanism. measurement.
In this model, an “airbag” of particular operation is included. Inside this strap, there is an airbag with a mini pump that inflates and deflates the airbag, and allows the use of an oscillograph to recognize systole and diastole.
The precision established by Huawei with the Watch D is +- 3 mm Hg, compared to the final measurement. Combined with Huawei’s TruBP blood algorithms, the team determines if the measurement position is not correct or if micro-adjustments to the straps are required to get the mechanism going.
In short, it takes less than 40 seconds to use this system, which only requires placing your hand at shoulder level and relaxing your body. By starting the mechanism and automatically inflating the airbag, we will feel how the strap intensifies the squeeze to the point of being something intense. Calm down, it’s harmless. After a few seconds, the screen shows the metric and you archive it in the app.
Quantification on another level. This is a system complemented by the Huawei Health app and its classic tools under Harmony OS 2 – yes, you must install Huawei services on your phone to use the device -, with which you will have a general map of your health. This generation of Huawei TruBP sensors has already been well received in the GT versions, but now they are complemented by ECG and blood pressure data.
What I do not like. We could go further, but the equipment works like other Huawei watches: same interface, same tools, same number of steps for installation. The obvious problem is that hardly anyone needs such a watch.
I explain. We are facing a first step in the search for precise control tools that fit into a small space, and this team complies with it. However, it is located far from the aesthetic and functional standard of the current market. Nobody needs a piece of equipment this big on their wrist all day long.
However, it is good to see that we are facing a promising future in which technology will find the way to adapt this solution to a more portable and comfortable form factor.
Understandable battery. With all these functions – come on, you are inflating a bag – the equipment is capable of sustaining battery between 5 and 7 days. Wireless charging powers the watch from 0 to 100 in … and power consumption could change based on the use of tools like ECG or blood pressure.
Huawei Watch D Is it worth it?
This is where the issue is unavoidable. As a clock, the operating system runs a bit slower than other clocks. A GT 3 Pro could easily be a better buy for any user. It is that argument that should determine the need for this item: who should buy it?
To begin with, there are relatives who could have on hand the possibility of having pressure measurements at any time of the day and have an idea of how they are doing. Be careful, Huawei confirms that this is not a medical tool, and that the results should not be taken more than as a reference.
So is it okay that this watch exists? Yes, as a first step on the road to optimization. Will it be worth getting? For this differential, we could bet on our own blood pressure monitor at home. However, I am excited to see Huawei’s will in unexplored terrain, in which the following generations are called to improve the size and comfort of the watch. More than an item to buy today, it is a format to watch for tomorrow.
Still, it’s cheaper than an Apple Watch.
