The Huawei Watch D is a well being smartwatch with a distinction, because of its distinctive built-in blood strain monitor.
Not like Samsung’s blood pressure monitoring smartwatches, Huawei is delivering that help with out the necessity for calibration with a cuff blood strain monitor. It guarantees the identical margin of error as an at-home monitor, which usually requires strapping on an inflatable cuff to take readings.
After launching in China in 2021, the Watch D has now grabbed the suitable regulatory approval in Europe to take its severe well being monitoring powers additional afield.
It is dear and has restricted availability within the US – far more than the Huawei Watch GT 3, Watch 3 and Watch GT 3 Pro.
So, does this smartwatch ship an important place to trace your vitals? Right here’s our complete tackle the Huawei Watch D.
Design and luxury

The Watch D couldn’t look any totally different from Huawei’s different watches. Its chunky, rectangular-framed case offers it the texture of a medical system versus a smartwatch like an Apple Watch or a Samsung Galaxy Watch.
It’s not uncomfortable per se, but it surely merely isn’t as fairly or as slim as Huawei’s different watches.
There’s a good massive 1.64-inch, 456 x 280 AMOLED show to stare into no less than and whereas it’s not the very best AMOLED panel you’ll discover on a Huawei smartwatch proper now, it’s nonetheless excellent by way of brightness, colours, and might be always-on.
On the appropriate aspect of the case, you’ve received two bodily buttons. The highest one wakes up the show and will get you into the primary menu display screen, whereas the underside Well being one offers you fast entry to its blood strain measurement mode.

The BP cuff strap
First, we’ve got to speak about how the Huawei Watch D works. It would not take blood strain readings through the optical PPG sensor. It truly incorporates an inflatable cuff into the strap. In order that does make it fairly chunky to put on.
The fluoroelastomer strap feels very aspect and that’s mandatory for a few causes.
The principle cause is the inflatable airbag that takes the BP readings matches inside it, so it is wanted for a dependable match. It feels fairly large on smaller wrists and actually implies that the Watch D is solely a tool for these with a vested curiosity in blood strain.
You’ve received each medium and enormous straps with that airbag included. Should you’re undecided which one you have to be utilizing, Huawei does provide an explainer together with a wrist circumference ruler instrument to be sure to get the appropriate strap in your wrist measurement.
The watch comes with the big strap model put in, which we needed to take away to clip within the extra appropriate medium-sized one.

An necessary factor to notice is that Huawei gives a unique stage of water safety on the Watch D in comparison with its different bathe and swim-friendly watches.
The Watch D carries an IP68 ranking versus the 5ATM one included on its GT watches.
Which means it could deal with being submerged in water for as much as 30 minutes as much as 1.5m depth, so it is good for the bathe however Huawei would not advise swimming.
Blood strain monitoring
Wareable
There are two massive options that separate the Watch D from Huawei’s different watches. That’s the power to take blood strain and ECG coronary heart price measurements.
These ECG measurements are delivered similarly to the Apple Watch and Samsung Galaxy Watch. The strategy to blood strain monitoring, nonetheless, is totally different from something we’ve seen on a smartwatch thus far.
We’ve seen Samsung introduce the power to take blood strain measurements by its optical sensor know-how, which first requires calibration with a conventional blood strain monitor. It additionally solely works when that watch is paired to a Samsung cellphone.
Within the case of the Huawei Watch D, that is one thing that works with iPhones and Android telephones. We primarily used it paired to an iPhone 14 and had no issues getting issues up and working and taking measurements.

So, how does it work? A lot is all the way down to the straps included, which characteristic an airbag that inflates in an analogous solution to the way in which a cuff inflates on a conventional blood strain monitor.
Together with Huawei’s personal TruBP blood strain algorithms, the Watch D is ready to take a 30-second measurement and generate the identical systolic, diastolic and pulse measurements.
Huawei additionally contains some extra options like posture detection or the power to detect motion throughout measurements, which is able to influence the reliability of readings.
Like ECG measurements on the Watch D, it is a characteristic that has the mandatory regulatory approval to have the ability to provide insights into whether or not blood strain is regular or abnormally excessive, which you possibly can then take to a medical skilled to hunt recommendation.
A low blood strain (also referred to as hypertension) of lower than 120/80 (systolic/diastolic) might be a sign of an underlying well being downside.
Huawei says its monitor has the identical +3 mm Hg margin of error as your typical dwelling blood strain monitor.
We’ve been utilizing the Watch D over just a few weeks, capturing blood strain readings alongside a Kinetik blood strain monitor and plotting that information manually inside Apple Well being.
What we discovered over these weeks is that when these readings on the watch that weren’t interrupted by motion or incorrect posture, had been usually in line or inside that margin of error Huawei promised.
Ranges of these readings over that interval usually informed an analogous story as effectively.

Taking a measurement may be very simple. We tended to faucet the blood strain studying icon on the primary watch face to take a measurement.
You’re instructed to maintain each toes on the ground and lift your arm in direction of your coronary heart however to not relaxation your arm in your chest. Throughout that point, you’ll hear the strap initially softly squeak after which it gently begins to increase.
On the watch display screen, you’ll see a gauge flicker up because it takes the studying after which when the strap deflates it’ll current your SYS/DIA and pulse information. Taking measurements wasn’t a problematic course of. There have been a few events the place the cuff was struggling to totally deflate after measurements.
Wareable
The place Huawei does a extremely good job is the way in which it presents this information on the watch and within the companion app.
On the watch, you possibly can see measurement data for as much as 60 of the newest measurements, you possibly can change items of measurement and you may even do a visitor measurement if another person desires to verify their blood strain.
Simply be sure that the appropriate strap measurement is on although.
Wareable
Within the app, you possibly can see your most up-to-date readings from the Well being tab after which soar in to see common information plotted over the day, week, or month.
There’s a great explainer of your information, which relies on the Nationwide Well being Fee Publication and Medical Establishment Tips in line with Huawei.
We may see fairly rapidly numbers generally had been deemed regular although pulse price had jumped once we’d been unwell.
It could maybe be helpful right here to have the ability to delete anomalous measurements which have been impacted by motion or incorrect posture. However that apart, Huawei has carried out a very nice job with the benefit with which you’ll take blood strain readings and the way in which information is delivered and offered on and off the watch.
ECG for added well being abilities
Wareable
If blood strain monitoring abilities weren’t sufficient well being monitoring options for you, Huawei’s Watch D does additionally pack in an ECG sensor that’s able to detecting atrial fibrillation and a extra regular sinus rhythm and gives a extra correct solution to measure your coronary heart price.
It’s a single-lead setup that’s constructed into the Well being button on the watch, the place you’ll want to position your finger for 30 seconds to take a measurement. That is the way in which Apple, Samsung and Fitbit do that as effectively.
Wareable
Then you possibly can head over to the Huawei Well being app and dig into that information within the Coronary heart part of the app. You possibly can see readings for the day and classification of the studying together with a graph of the studying.
We examined it alongside Apple’s ECG sensor and the information for readings got here up the identical on our readings, so we’re joyful that it appears to be according to different ECG-packing smartwatches and means Huawei has one other helpful well being characteristic that may provide some perception into elements of your coronary heart well being.
Smartwatch abilities
Wareable
Should you’re hoping that the Watch D goes to provide the identical wealthy smartwatch expertise as its different cheaper watches, then that’s not what you get right here. Huawei offers you sufficient we’d say, however there are some lacking options you do discover on its GT collection watches.
We’ll begin with what’s right here and that’s with the ability to do issues like view notifications, management music taking part in in your cellphone, and look at climate forecasts. There’s fairly a pleasant assortment of watch faces to select from right here too, with extra provided inside the Huawei Well being app.

The notification help works effective, although from an iPhone you possibly can’t act on the notifications bar clearing your feed.
The devoted widgets for issues like climate and music are effectively optimized to that rectangular display screen as effectively, however one thing we’ve got seen in our time is that interacting with the software program isn’t fairly as slick or easy as it’s on Huawei’s different watches.
It actually doesn’t really feel prefer it’s packing the identical parts to cowl issues within the efficiency division.
So what do you miss out on? You don’t have entry to Huawei’s AppGallery storefront to obtain apps, there’s no built-in music participant or the power to take calls through Bluetooth with no LTE performance on board both.
It’s a stripped-back Huawei smartwatch, however there’s much more right here than we anticipated and if you happen to’re joyful with the ability to verify in in your notifications or the climate and need to change up these watch faces now and again, then the Watch D has received you lined.
Helpful sports activities and well being extras
Wareable
Huawei doesn’t provide the full complement of its sports activities monitoring, basic wellness monitoring, and exercise monitoring options – but it surely does provide you with greater than sufficient to make the Watch D greater than helpful exterior of its extra targeted well being monitoring abilities.
We’ll begin with sports activities monitoring, the place there are monitoring modes aplenty.
It’s important to reside with out the swim monitoring due to that decrease water resistance ranking.
It does cowl profiles for indoor and outside working and biking and there are modes for indoor exercises like skipping and rowing right here the place you possibly can file exercise-specific metrics.
There’s GPS on board, but it surely unsurprisingly lacks the newer dual-band GPS mode we’ve seen crop up on different Huawei watches. You additionally don’t have the power to add and navigate routes just like the GT 3 and the GT Runner.
Wareable
On a roughly 7km run, it clocked us at 7.10km with a median tempo of 5.26 min/km. A Garmin on our different wrist recorded the run at 7.10km at 5.26 min/km tempo. GPS tracked routes and metrics like tempo seemed usually effective for us too.
Wareable
Coronary heart price graphs and information didn’t fairly match as much as a chest strap and on a really easy-paced indoor run, the center price information was effectively off from a Garmin HRM-Professional Plus chest strap monitor.
Wareable
In an indoor row, it delivered related information to the normally dependable row monitoring on Garmin for whole and common stroke charges, so there’s some good and dangerous right here on the sports activities monitoring entrance.
The exercise monitoring is acquainted too. You’ve received an analogous devoted exercise monitoring widget on the watch and off it, you possibly can delve into when these steps are occurring and the actions they arrive from. Step totals tended to be round 500-1,000 steps out of comparable monitoring by Oura and Garmin.
Wareable
There’s sleep monitoring right here too with sleep stage breakdowns, sleep factors and it could observe respiration high quality right here as effectively. Core sleep information generally appeared to color an analogous image to Garmin’s bettering sleep monitoring, with related sleep graphs and roughly related sleep stage breakdowns.
Wareable
It is a watch that may observe your coronary heart price, stress, pores and skin temperature, and SpO2 ranges 24/7 and that’s unlocked from Huawei’s newest Tru Seen optical sensor know-how.
Resting coronary heart price and coronary heart price ranges tended to match up with Garmin’s steady monitoring, which we’ve discovered performs effectively generally.
Stress monitoring requires taking a fast survey, which includes questions like asking if you happen to get simply aggravated when somebody interrupts your work and utilizing coronary heart price variability measurements to gauge whether or not stress is regular or excessive.
Capturing SpO2 information repeatedly appeared effective generally although there have been gaps in our information and the information isn’t put into any type of context not like a few of the different metrics on provide right here.
Wareable
It’s an analogous story when monitoring pores and skin temperature. Once more, this isn’t a characteristic designed for medical use, however we had been no less than in a position to see when a virus hit that pores and skin temperature jumped barely over the conventional 33-37 Celsius.
Battery life
Wareable
Huawei says you possibly can count on a typical battery lifetime of as much as 7 days in between prices. That utilization relies on what Huawei says are typical utility situations. That features measuring blood strain 6 occasions a day, monitoring sleep and exercising for 90 minutes every week.
We’d say that the Watch D is able to going for a full week, even with some average to heavy utilization of key options.
Each day battery drop-off was anyplace from 10-15% on most days and utilizing the GPS for round 40 minutes of working noticed battery drop by 4%. Unsurprisingly, in case you have the display screen set to always-on, that does eat into that point significantly.
In the end, there’s no regarding drain, even with steady sleep, coronary heart price, and SpO2 monitoring in use.
It may not be the very best battery life you may get on a Huawei smartwatch proper now, however we’re joyful to see it’s comfortably every week as opposed to some days. If that display screen isn’t set to all the time on.
With regards to charging, this rectangular watch makes use of an analogous white, charging disc equipped with different Huawei watches you possibly can gently drop the watch onto, however lacks any type of quick charging help.
