Huawei Watch D3 review: Nothing else on your wrist does health tracking quite like this

I’ve reviewed enough smartwatches that new health features rarely make me stop and stare anymore. Optical heart-rate sensors get better, sleep algorithms become more detailed, and there’s another readiness score that might make me more anxious about my health. All of this is useful progress, but the underlying hardware usually looks very familiar.

But a few weeks ago, Huawei sent me a smartwatch with a tiny blood-pressure cuff hidden inside its strap. I had heard about this unique blood-pressure mapping watch from the brand before, but this was my first time trying anything like it. My first reaction was fascination. I wrote an entire feature about the engineering because I couldn’t get over the fact that Huawei had stuffed an inflatable bladder, pressure sensor, and miniature pump into something sitting on my wrist.

What I didn’t know then was whether I’d still care a month later. With most tech products, the cool new feature seems pretty cool, till you get kind of bored. I love the fact that I get to try some of the coolest gadgets out there, but sometimes you just want things to stay out of your way. Not having to interact with one more feature keeps the experience… minimalist, if you will.

So after initially spamming the blood-pressure measurement several times simply because I could, I eventually settled into taking roughly two or three readings per day. Sometimes it happened in the morning. Sometimes in the evening. Occasionally I found myself checking it when I was stressed. Somewhere along the way, the novelty became a daily little habit.

This isn’t merely an impressive medical gadget squeezed onto your wrist anymore. It’s become a genuinely good smartwatch that happens to carry a one-of-a-kind type of health feature in the category.

Quick Take

I used the Gold and White Watch D3 for a little over a month as my primary smartwatch, including while traveling, and paired it with multiple Android phones, including the Pixel 11 Pro and Vivo X500 Pro. Before that, I had been using the Oppo Watch X3.

The defining feature is the inflatable cuff built directly into its strap. Rather than relying purely on optical estimates, it uses an oscillometric measurement much closer in principle to a traditional blood-pressure monitor. Huawei also supports 24-hour ambulatory blood-pressure monitoring, or ABPM, which can collect readings throughout the day and overnight.

All of this sounds quite medical (and technical). Though when you’re actually wearing it, the experience is quite seamless. The D3 is comfortable enough that the internal airbag never bothered me by being in some corner of my awareness. The screen is bright, battery life reaches roughly six days in my use, notifications work reliably, fitness tracking is perfectly competent, and Huawei Health does a good job turning all of its medical data into reports that an ordinary person can understand.

It’s got a few rough edges too. Huawei’s software ecosystem remains behind Wear OS and watchOS; this isn’t a watch for the great outdoors or intense sports activities (like swimming), and the unusual strap won’t be equally comfortable for everyone. If you actively care about blood pressure, however, there is barely anything else quite like it.

Huawei Watch D3 design and comfort: The medical hardware is barely noticeable

Quick Take: Fitting an airbag inside a watch strap is an engineering achievement, but making me forget that it’s there is pure witchcraft.

Nobody looking at my wrist would know what the Watch D3 can do. To many, it seemed like any other fitness tracker/smartwatch. Some even confused it for the Apple Watch, and I can’t blame them. The rectangular design inevitably carries a little Apple Watch DNA. But I have to say that the Gold and White variant I received looked very elegant.

Its aluminum body doesn’t have the extravagant titanium and sapphire construction of Huawei’s Watch GT 7 Pro, but it still comes across as sturdy and premium enough for the price. After more than a month, mine hasn’t picked up visible scratches or scuffs. At 11.3mm thick, it also avoids looking like a miniature medical instrument strapped to my arm.

Speaking of the airbag, I barely felt it when it wasn’t inflated. The strap is thicker than an ordinary smartwatch band, but I didn’t experience pressure points or discomfort during normal wear. It trapped a little sweat on warmer days, though it was never enough to make me want to remove it. Even overnight, it was comfortable once I fell asleep.

This won’t be a universal experience though. A few reviews out there also talked about how the airbag assembly is less comfortable than a typical smartwatch strap. So this might be worth noting if you are planning to get one in the UK or Europe. Wrist shape is definitely important here, and Huawei has thought of this as well.

The company helps by including different airbag sizes and a wrist-measurement tool in the box. Setup takes a little longer because you’re asked to properly measure your wrist and select the appropriate cuff size. I fully support these extra steps while setting up. This is one device where I would rather spend a couple of more minutes during setup if it improves comfort and measurement consistency later.

Design and comfort score: 8/10

Huawei Watch D3 display: Big, bright, and sharp

Quick Take: Huawei’s 1.92-inch AMOLED is bright, sharp, and exceptionally easy to read outdoors, though the bezels could still shrink.

Huawei rates the 1.92-inch AMOLED for up to 3,000 nits, and while peak-brightness claims rarely describe normal use, the only important part is that I could comfortably read it in direct Delhi sunlight. I never had to manually crank the brightness. Auto brightness simply handled it. Meanwhile, at night, it dims low enough to avoid becoming a tiny torch strapped to my arm.

Colors are vibrant, blacks are appropriately deep, and animations look smooth. The rectangular format also suits this watch because the D3 spends a decent amount of time displaying charts, BP numbers, reports, and lists. It’s not all perfect, especially when you look at the bezels. There is unused space around the panel, and it’s one of the easiest areas Huawei can improve on next time.

I also used the always-on display for part of my testing. It looks good, but battery life takes an obvious hit, so I eventually preferred leaving it off.

Display score: 9/10

Huawei Watch D3 blood pressure sensing: Finally, no gimmicks

Quick Take: A blood-pressure test takes about 30 seconds, feels like a firm grip around the wrist, and quickly became something I did almost every day.

This feature alone is why you buy the Watch D3. Start a blood-pressure measurement, and the airbag hidden inside the strap begins tightening around your wrist. It feels a bit strange the first few times, reminding you of the time an arm cuff put an unnatural amount of pressure. But then, it all becomes routine.

A measurement takes around 30 seconds in my experience. The cuff applies a noticeable amount of pressure, but I’d describe it as a strong grip rather than anything painful or uncomfortable. Just remember, there is a technique involved. Huawei wants you sitting still, with your arm positioned correctly around heart level. Talking, moving, wearing the strap incorrectly, or holding your arm badly can ruin a reading. The watch caught me talking a few times and explicitly told me to stop.

A health feature like this should be annoying when I’m doing something likely to undermine the result. Once I learned the posture, it became second nature. The results are also clearly presented, and I found both individual readings and longer-term trends useful.

I wasn’t able to compare my D3 directly against an upper-arm blood-pressure monitor, so I won’t pretend my testing validates its medical accuracy. External tests have found that readings were generally within ±5mmHg of its arm cuff reading. But it’s an important reminder that fit, posture, measurement technique, and individual physiology are worth considering. I’d use the D3 for tracking and reports, especially over time. I would not use one smartwatch reading to self-diagnose a medical condition.

Blood pressure and health score: 9.5/10

ABPM: Where the D3 is in a league of its own

ABPM is where the Watch D3 actually separates itself. I ran several ambulatory monitoring sessions with readings scheduled roughly every 30 minutes. Setup is simple, and during the day the watch gives enough warning that you know what’s happening. Most of the time, it barely interrupted what I was doing.

A couple of measurements failed while I was working out and resulted in inaccurate or erroneous readings because my posture wasn’t right. Over a full session, I generally saw only two or three failures. Nights had a similar result. Most importantly, perhaps, the cuff never woke me up. Again, this is one of those things that won’t be the same for everyone, and even individual fit and sleep habits can have very real differences.

The report from Huawei recognises this, though. It separates daytime and nighttime data clearly, shows averages and trends, and lets you export the results. My blood pressure remained stable and in the normal range, so the report wasn’t personally revelatory. But that doesn’t make it pointless.

My mother has had blood-pressure issues in the past, and this is exactly the sort of product I can imagine giving her. Now, we don’t have to pull out an arm cuff several times a day; the Watch D3 can build a far denser picture of what is happening over 24 hours. That report could then be shown to a doctor (again, as a reference).

This is also where the recent research around longitudinal wearable BP monitoring becomes a talking point. Research suggesting that continuous cardiovascular data may eventually help flag hypertensive-crisis risk days in advance highlights why trends across hours and days can be more meaningful than obsessing over a single number. The Watch D3 does not claim to predict a crisis days in advance, but the wider direction of wearable health research makes its ability to collect repeated measurements especially interesting.

The rest of the health tracking is excellent too

Quick Take: Blood pressure gets the attention, but heart rate, sleep, SpO₂, HRV, stress, and Huawei’s wider health dashboard make the D3 far more than a one-feature wearable.

The cuff dominates every conversation about this watch, which is slightly unfair to everything else Huawei has built. There is a lot more on offer with the Watch D3. Heart-rate tracking looked consistent during everyday wear and workouts. The main inconsistencies I encountered happened when the watch wasn’t fitted correctly, another reason to take Huawei’s wrist-sizing process seriously.

SpO₂ is particularly sensitive to technique. If I ignored the instructions or let the watch sit poorly, readings could differ by several percentage points. That’s enough variation to look alarming if you treat every number as absolute truth. Huawei also offers ECG functionality, arrhythmia analysis where supported, HRV, stress measurements, temperature data, Physical Readiness, and Health Glance.

I don’t think every metric needs to become part of my daily routine. The value here is that the D3 can collect a broad set of signals around the one metric it specializes in.

Sleep tracking: Even the cuff didn’t ruin it

I didn’t sleep with the Watch D3 every night. But when I did, sleep and wake detection seemed quite accurate. Huawei breaks the night into REM, deep, and light sleep, and the presentation is easy enough to understand without turning bedtime into a spreadsheet. It also correctly picked up nighttime awakenings.

The surprising part is that the cuff didn’t make sleeping more uncomfortable. Even during overnight blood-pressure monitoring, inflation never woke me. For someone who actively needs nighttime BP data, that tradeoff is worth it. Though it would’ve been nicer to have a slightly slimmer profile with the watch.

Huawei Watch D3 fitness capabilities: Good, but this isn’t Huawei’s athlete watch

Quick Take: Walking, running, treadmill, and cycling tracking all worked well, but serious athletes are better served by Huawei’s GT line or a dedicated Garmin.

I tested the D3 across walking, running, treadmill sessions, and cycling. Heart-rate tracking stayed consistent, route data looked accurate in my testing, and auto workout detection was reliable as well. Huawei offers more than 100 workout modes, so there is plenty here for ordinary gym users.

I wouldn’t buy the Watch D3 specifically for serious running or outdoor sports, however. Not because the fitness tools are bad; they are simply secondary to the cardiovascular-health mission. The GT 7 Pro is a better fit if I care about ruggedness, hiking, navigation, long-duration outdoor activity, and maximum battery life. My colleague’s GT 7 Pro testing found excellent GPS performance and more than ten days of normal battery life, alongside much tougher titanium, ceramic, and sapphire construction.

The D3 is also not the watch I would take swimming. Huawei’s cuff and inflatable hardware mean this is a very different proposition from a conventional sports watch, despite its IP68 rating. Reviewers specifically caution against swimming and prolonged water exposure because of the airbag system.

Fitness score: 8/10

Huawei Watch D3 software and health ecosystem: Capable, but not my favorite

Quick Take: Huawei Health handles the D3’s complicated medical data surprisingly well, while the smartwatch still lacks the polish and app depth of my favorite Wear OS watches.

My first setup was slightly frustrating because I was using a beta build of Huawei Health. This is more of an early test-unit hurdle, especially in regions where this isn’t available. But the stable build shouldn’t have those issues.

Blood-pressure readings sync immediately, health dashboards are easy to navigate, and the ABPM reports are comprehensible despite the amount of information they contain. Notifications were reliable, working across updates from WhatsApp and Gmail; quick replies were available, calls worked, and I didn’t encounter meaningful bugs during my month of testing.

So overall, it works like just any other smartwatch. My only complaint would be the aesthetics. Coming directly from the Oppo Watch X3, I simply prefer the way Wear OS’ interface looks and moves. Huawei’s UI is perfectly functional, but it doesn’t have the same visual polish for me. There’s also the broader ecosystem to consider. Huawei’s third-party app selection remains much smaller than Wear OS or watchOS. The whole reason to buy the D3 lives inside the Huawei Health app, which is also a little cluttered.

Software score: 7.5/10

Calls and everyday smartwatch features

Quick Take: Calls, notifications, music controls, and basic smartwatch features work reliably. Just remember there’s no standalone cellular connection.

Outside of all the health tracking, Huawei Watch D3 needs to work as a smartwatch. And yes, it does that part well. Trying out Bluetooth calls, the other person could hear me clearly. The speakers were usable outdoors, and I didn’t encounter random disconnects. I personally don’t enjoy taking calls through a smartwatch speaker, but the functionality is there, and it works.

Music controls are present, NFC is supported, and Curve Pay works in eligible markets. I couldn’t meaningfully test payments because of regional availability. The Watch D3 skips LTE/eSIM support as well, which isn’t something I particularly cared about because I nearly always have a phone nearby, and I don’t think standalone connectivity is especially important for the health-focused buyer Huawei is targeting.

Huawei Watch D3 battery life: Almost a week without thinking about it

Quick Take: Six-day real-world battery life makes the D3 easier to live with than an Apple Watch or most Wear OS alternatives.

With the always-on display disabled and automatic health measurements active, I generally got around six days between charges. On occasion, when I was taking it off for a bit, I managed to go over a week without charging. So let’s just say battery anxiety felt like a thing of the past. Even the more powerful Oppo Watch X3, which also had impressed me with its endurance.

Considering how Huawei is pushing continuous tracking, a watch becomes less useful if you take it off to charge every night, or even every other night. AOD noticeably reduced endurance in my testing, so I kept it off. ABPM is the other extreme. Activating the pump dozens of times over 24 hours dramatically increases drain, which is why Huawei only rates that mode for roughly one day.

Huawei advertises approximately 75 minutes for a full charge, but in my experience, it actually felt faster. 50% charge usually took around 20 minutes, and a full charge was just under an hour. Charger, starting percentage, temperature, and software can all affect that result.

Battery score: 9/10

Despite everything, it doesn’t feel medical

The Watch D3 carries CE-MDR medical-device certification in Europe for its supported blood-pressure functions. This changes how seriously I look at the hardware. Even mechanically, I trust the concept more than approaches that purely infer BP trends optically. I am obviously not suggesting that I’d trust it blindly and ignore a doctor, but the figures are great for reference.

I still find that engineering just as fascinating as the day I first received it. I expected the inflatable cuff to become the kind of feature I showed friends twice before forgetting about it. I ended up checking my blood pressure every day. With the initial generations, the Watch D series seemed like a medical device that doubled as a smartwatch. Now, it seems like a lot more confident as both.

And the best part is that it doesn’t scream medical/hospital equipment — nor does it look like a prototype concept. For people with a reason to monitor blood pressure regularly, that normality might be the most important feature of all.

Should you buy?

The Huawei Watch D3 costs £399.99 in the UK and €449.99 in Europe. If you have no interest in blood pressure, I wouldn’t buy it solely because the cuff seems unique. But if you are even remotely interested in cardiovascular health, my advice changes immediately.

The D3 is the only mainstream smartwatch I’ve used where I can take a genuine cuff-based BP reading whenever I want, especially with a mechanical element rather than optical. I can even collect measurements across an entire day and night and turn them into a usable report, all the while not feeling like I’m wearing a specialized medical device.

It becomes even easier to recommend when you know you, or someone is at risk of hypertension, who is already monitoring BP regularly. I’d happily give one to a parent.

Why not try these?

Huawei Watch GT 7 Pro

Choose the GT 7 Pro if you want the stronger all-round Huawei smartwatch. Its titanium, ceramic, and sapphire construction is more premium, its outdoor tracking is more ambitious, it’s suitable for serious water use, and battery life can stretch well beyond a week. The D3 is the better health specialist, particularly for BP monitoring.

Apple Watch Series 12

The Series 12 starts at $399 and gives iPhone users a dramatically deeper app ecosystem, cellular options, improved health sensing, Readiness, and Apple’s broader watchOS experience. Apple is increasingly interested in hypertension and cardiovascular trends, but it still doesn’t provide the D3’s on-demand inflatable-cuff measurement.

Samsung Galaxy Watch 9

Samsung’s Galaxy Watch 9 is a better choice for Android buyers who want Wear OS, LTE, Google apps, a much richer third-party ecosystem, and stronger phone integration. Samsung also offers substantial health functionality, but its blood-pressure approach in supported markets remains fundamentally different from Huawei’s integrated mechanical cuff.

Google Pixel Watch 5

The Pixel Watch 5 is arguably the more appealing general-purpose Android smartwatch, with Google’s software ecosystem and newer Blood Pressure Trends feature. That feature is built around longer-term optical trend analysis rather than taking a traditional systolic/diastolic reading on demand, which makes the two devices very different despite targeting some of the same health-conscious buyers.

Huawei Watch D2

If blood pressure is the specific feature you want and the older D2 is available at a significant discount, it remains the closest genuine alternative. The D3 is slimmer, lighter, and easier to wear, so I would choose it unless the price difference were substantial.

How I tested the Huawei Watch D3

I paired the Watch D3 with several Android phones, including the Google Pixel 11 Pro and Vivo X500 Pro. Before switching to it, I had been using the Oppo Watch X3. During the review period, I used it for everyday notifications and calls, blood-pressure readings, automatic health monitoring, walking, running, treadmill workouts, cycling, and several nights of sleep tracking.

I generally took one manual blood-pressure reading per day after the first several days of heavier experimentation. I also ran multiple 24-hour ABPM sessions with approximately 30-minute measurement intervals. I did not perform a direct comparison against a calibrated upper-arm BP monitor, so observations about my own BP results relate to consistency and usability rather than clinical accuracy.

Battery testing reflected normal use with automatic health readings enabled, the always-on display usually disabled, occasional sleep tracking, notifications, and daily BP measurements.

FAQs (Frequently Asked Questions)

Does the Huawei Watch D3 actually measure blood pressure?

Yes. The strap contains an inflatable airbag and miniature pump that perform an oscillometric pressure measurement. It isn’t simply displaying an optical estimate. Huawei’s supported BP features also carry CE-MDR medical-device certification in Europe.

How accurate is the Huawei Watch D3?

I wasn’t able to compare my unit directly against an upper-arm monitor. Independent reviewer comparisons have generally found close agreement, although results aren’t universal. There are relatively small differences in independent testing. So correct fit and posture are essential.

Is the cuff uncomfortable?

I found it comfortable enough to forget it was there during normal wear. Inflation feels like a firm grip but was never painful. Other reviewers have had mixed experiences, with some finding the thicker strap less comfortable, so wrist size and fit clearly matter.

Can the Huawei Watch D3 monitor blood pressure overnight?

Yes. Its ABPM mode can collect readings throughout a 24-hour period, including while you sleep. Overnight measurements didn’t wake me, but your experience might vary.

Can I swim with the Huawei Watch D3?

I wouldn’t recommend it. The D3 is built around an inflatable airbag system and, despite its IP68 rating, Huawei’s guidance makes it a poor choice for swimming, diving, or prolonged water exposure.

How long does the battery last?

Huawei rates it for up to six days during typical use and around one day with ABPM enabled. I consistently saw approximately six days with AOD disabled and automatic health monitoring active.

Does the Huawei Watch D3 work with Android and iPhone?

Yes. Huawei officially supports Android 8.0 or later and iOS 13.0 or later through Huawei Health. Feature availability can vary by phone and region.

Is the Huawei Watch D3 available in the US?

There is no official US retail release. Importing is possible, but health functions, NFC services, warranty support, and app availability may depend on region.
