Huawei Watch D2 review: One-minute review
If we had a ‘best for blood pressure’ category in our best smartwatches buying guide then the Watch D2 would be instantly catapulted into this position. It supersedes the Watch D that was released in 2022, and is looking set to reignite a watch series that was otherwise going to be consigned into the depths of smartwatch history.
Blood pressure monitoring in a smartwatch is an incredible achievement, a reality made possible through an airbag strip located behind the main watch strap. At first, I thought the strip would get in the way and be too uncomfortable to wear on a daily basis, but I was wrong. It sits neatly as part of the strip and (if anything) provides an extra layer of comfort.
Blood pressure readings appeared reliable and accurate, although the watch did struggle relatively regularly to get a reading at all. It required a certain level of accurate positioning on the wrist. I appreciate it’s a medical piece of equipment, but I’d like to see increased predictability in the Watch D3.
As good as the Watch D2 is for blood pressure monitoring, it is equally let down by its lack of advanced smartwatch features. At a cost of £350 (around $400 / AU$700), I’m disappointed not to see the ability to make contactless payments, listen to music through Spotify or Amazon Music, or even listen to audio messages on WhatsApp.
I know a lot of the cost can be attributed to the advanced blood pressure capabilities, but I think that has limited this watch to a rather niche group of people and their needs. Wide market appeal might therefore be lacking.
The watch is certified by both the EU’s Medical Device Regulation body and China’s National Medical Products Administration. This opens up an almost global market, but the distinct lack of release in the US might further hamper appeal.
Having worn this watch for a number of weeks, I’m left with an overall positive feeling. It looks great, performs well, and provides an adequate extension to my smartphone. There’s still room for improvement, which I’m sure will come in future releases but for now the D2 represents an important step in smartwatch development.

Huawei Watch D2 review: Price and availability
- £349.99 in the UK
- Not available in the US / AU
- Also available in China
The Huawei Watch D2 is available in the UK at a price of £349.99. Blood pressure monitoring is certified by the EU’s Medical Device Regulation body. The device is also available in China but that’s as far as Huawei’s market’s stretch.
Huawei continues to be banned in the US, which seriously limits the company’s markets. Otherwise, the watch isn’t cheap and is missing a few key smartwatch features at this price point, although the revolutionary blood pressure monitor makes up for it.
Huawei Watch D2 review: Design
- Good-looking design
- 1.82 inch AMOLED
- Thick watch
Upon taking the Watch D2 out of the box my first impressions of the design were pretty positive. The 1.82-inch AMOLED display takes centre stage, providing a substantially sized screen for showcasing watch faces, health data, and notifications.
The colour display has a resolution of 480 × 408 pixels with a PPI of 347. Text and graphics look absolutely fantastic with a high level of clarity, definition, and vibrancy. There were no signs of pixelation or definition problems.
The display is encased by a black or gold case, which frames the watch nicely. Considering how impressive the display is, it would benefit from a much thinner bezel, especially at the top and bottom of the display. The watch itself is sized at 48 × 38 mm. The aluminium alloy case continues back to the rear of the watch where a black plastic panel takes over. The thickness is 13.3 mm, although this is at the thinnest location and excludes the sensor area.
This is one of my biggest gripes with the watch design: like its predecessor, it’s just far too thick. The sooner Huawei is able to recess that sensor further into the watch the more comfortably it will sit on the wrist.
To the side of the watch is a rotating crown and a function/ECG button. These perform well and enhance the overall operation of the watch. I did find myself using the touchscreen more than the buttons but they’re there if you want them.
The watch is built with premium materials, giving significant strength to the quality and level of durability. I had no concerns that I was going to damage the watch or that any individual parts weren’t going to stand the test of time.
There are two watch strap options, including ‘Black Fluoroelastomer’ and ‘White Composite Leather’. I was testing the former. The material looks great and, more importantly, feels nice on the wrist. The locking mechanism provides a quick and easy way to take the watch on and off.
The blood pressure monitor airbag strip is directly connected to the watch strap itself. I couldn’t initially see how this was going to be comfortable but, in reality, it provided an extra level of cushioning.
The watch ships with a wireless USB-A charger, which is better than most that I have tested. The watch magnetically connects to the charger and doesn’t require the watch to be in any particular orientation.
Huawei Watch D2 review: Features
- Blood pressure monitoring
- Extensive tracking capabilities
- Lacks advanced key smartwatch features
The single biggest standout feature of the Huawei Watch D2 is the Ambulatory Blood Pressure Monitoring (ABPM). ABPM is delivered through a 26.5 mm ultra-narrow mechanical airbag that is attached to the inside of the watch strap. It inflates quickly and easily, providing everything required to take this vital health metric. The idea behind the feature is to provide blood pressure monitoring at will without a large cuff. So, whether you’re working, exercising, relaxing, or sleeping, it’s now easier than ever to perform ABPM tests.
The Watch D2 lets users run a 24-hour auto-monitoring plan. This is helpful for noticing trends across a whole day, including when you’re sleeping. Do be prepared to be woken up through the night though unless you have a special skill of sleeping through the air-bag inflation.
Another relevant feature is the ECG analysis. Huawei have improved their technology from the Watch D, now providing more accurate and responsive results. If you’re interested in this level of detail, then you can get the data required to help you identify the potential presence of common heart conditions.
Additionally, Huawei have included a sleep mode that includes heart rate, SpO2, respiratory rate, and abnormal breathing tracking. As you wake in the morning, you can see detailed results through the Huawei Health App. It also includes white noise, natural soundscapes, and relaxing music to help you get to sleep.
The Watch D2 also includes a range of smartwatch features, including notifications, making and receiving calls, and listening to offline music. Unfortunately there are quite significant limitations, including the inability to make contactless payments, listen to WhatsApp audio messages, or listen to music through Spotify or other music providers. It’s all got to be done through your phone.
Huawei Watch D2 review: Performance
- Accurate blood pressure monitoring
- Good exercise tracking
- Responsive display
ABPM is a rare commodity in a smartwatch, so I was keen to test the accuracy and reliability of the feature. Having set the watch up and got the watch and my arm in position, I proceeded to set the watch off on its monitoring. With the air-bag inflating, I was keen to see what the results would be.
I ran the same tests numerous times and gained very similar results, which showed a pleasing level of consistency. I’m aware of what my normal blood pressure levels are and the watch delivered results within that spectrum.
I did have some problems with reliability and at times, I couldn’t get the watch to take the measurement at all. This will have mostly been down to my incorrect positioning of the watch but despite that, I would like to have seen more consistent monitoring capabilities.
Other health tracking metrics are measured with ease, as they don’t require quite the same level of mechanics or precision on positioning. Its sleep tracking accurately detected all my wakings as well as times that I was in deep or light sleep.
I then took the watch out and about while I walked, ran, played football, and cycled. The D2 picked up GPS without any problems at all and accurately detected where I was located. All of this was displayed on maps and I experienced no problems with the watch getting this wrong. Metrics were all recorded and tracked without problem and the Huawei Health app proved a faithful companion for digging deeper into those.
Battery life is advertised as six days with normal usage. I experienced a range of different lengths with a greater range when I was only doing exercise tracking and basic smartwatch features as well as a shortened range when using it more intensely.

Huawei Watch D2: How I tested
I’ve enjoyed wearing the Huawei Watch D2 for several weeks and have tested as many of its features as I possibly could. I focused on blood pressure monitoring, ECG analysis, and exercise tracking. I tracked walking, running, football, and cycling to give a good spread of activities.
I paired the watch with the Huawei Health app to get the complete health tracking experience offered by Huawei.
