Huawei Watch D3 Review: New Blood Pressure Smartwatch for 2026

With the Huawei Watch D3, the producer is launching the third technology of its medically licensed blood strain smartwatch and confidently positioning it as “more than just a smartwatch”: a blood strain monitor for on a regular basis use that gives 24-hour ambulatory monitoring, blood strain readings earlier than and after exercises, and a considerably expanded well being and household ecosystem. We wore the Watch D3 for a number of weeks as a part of our day by day routine, examined all its well being options, and put the watch beneath the microscope in a direct comparability with the Watch D2. Read all about it in our Huawei Watch D3 assessment.

Technical Specifications of the Huawei Watch D3

Watch D3 vs. Watch D2: A Direct Comparison

A direct comparability between the Huawei Watch D3 and the Watch D2 reveals simply how vital the leap ahead is in comparison with its predecessor. It’s clear at first look that the brand new wearable has been noticeably modernized:

Overall, it’s clear that Huawei has made few adjustments to the tried-and-true core blood strain measurement operate itself, however has considerably expanded the encircling options. For D2 house owners who’re primarily glad with the blood strain measurement, the D3 provides, above all, a slimmer, lighter case, a greater show, and the brand new household, cost, and cellphone options as key promoting factors. The core measurement operate stays technically at a comparable stage however is now supplemented by licensed pre- and post-workout measurements for the primary time. When evaluating the 2 fashions aspect by aspect, the distinction in weight and thickness was by far essentially the most noticeable facet for us: The Huawei Watch D3 feels noticeably extra unobtrusive on the wrist.

Huawei Watch D3 Review: Design and Build Quality

There’s no query about it: The Huawei Watch D3 is a premium smartwatch, simply as you’d count on from the producer’s different fashions, such because the Watch FIT 5 Pro (assessment) or the Watch Ultimate 2 (assessment). At first look, the Watch D3 stays true to the sq. kind issue with rounded corners and the distinctive rotating crown that the D2 already featured—and which, visually, just isn’t coincidentally paying homage to the Apple Watch Ultra.

The actual progress solely turns into obvious in a direct comparability with the earlier mannequin: The case has shrunk from 13.3 to about 11.3 millimeters in top—a discount of about 15 %. The massive L-strap weighs about 35 grams as a substitute of 44 grams—a discount of practically 9 grams, or 20 %—whereas the smaller strap remains to be 6.5 grams lighter. In on a regular basis use over a number of weeks, we really observed the distinction: Despite the built-in air-cushion cuff within the wristband—which provides noticeably extra bulk than an ordinary smartwatch—we discovered the D3 to be a lot much less noticeable than the bulkier D2, even after sporting all of it day.

The show itself has grown from 1.82 to 1.92 inches, with a screen-to-body ratio that Huawei says has elevated by 6.4 % because of narrower bezels. On paper, the height brightness doubles from 1,500 to three,000 nits, and we had been in a position to affirm this in our take a look at: Even in vivid summer season daylight, the show remained simple to learn with out having to carry our hand over it to dam the solar. The physique remains to be made from an aluminum alloy with a again panel made from polymer fiber composite, which homes the required sensors and antenna know-how inside with out shielding radio alerts.

New to the lineup is the Mocha Gold colour variant: a gold-colored aluminum case with a sand-colored artificial leather-based strap, which can be obtainable at launch alongside a traditional black variant (HNBR rubber strap) and a lighter gold model with a white artificial leather-based strap. With this, Huawei is changing the D2’s earlier colour palette of black, white, and blue with a decidedly higher-quality, extra elegant colour scheme. A wrist circumference ruler can be included for the preliminary setup: Before the primary startup, we measured our wrist circumference and, based mostly on that, selected between the included quick, medium (M), or lengthy (L) strap, full with an identical air cushion. According to the spec sheet, it covers a spread from 130 to 210 millimeters; the setup itself took just some minutes.

Medically Certified Blood Pressure Measurement in Detail

The Huawei Watch D3’s key promoting level stays its blood strain measurement utilizing the oscillometric methodology—the identical measurement precept utilized in scientific upper-arm blood strain screens—relatively than counting on an optical PPG estimate. At its coronary heart is an ultra-slim mechanical air cushion, which Huawei says it developed based mostly on a “full-stack hemodynamic simulation model”: A two-layer air cushion with a circumferential edge is designed to attain comparably efficient compression and exact measurement, regardless of a cuff width of solely about one-fifth that of a standard blood strain monitor. A micro-pump contained in the case briefly builds up strain, and high-precision sensors then consider the change in strain.

Crucial to its classification as a severe well being system: According to Huawei, the Watch D3’s blood strain measurement is licensed each beneath the EU Medical Device Regulation (CE-MDR) and by the Chinese regulatory authority NMPA. These certifications affirm, at the least formally, that security and measurement accuracy have been verified by impartial our bodies—a distinction from many competing merchandise, which merely estimate blood strain with out requiring a comparable medical system certification.

For the preliminary measurement, the Watch D3 guides you thru a short setup course of: After deciding on the suitable wristband dimension, the measurement is began by way of the menu or instantly utilizing a customizable backside button; you then want to take a seat nonetheless and stay silent for about 30 seconds whereas the air cushion inflates.

During our several-week real-world take a look at, this shortly turned routine; the inflation was noticeable however by no means uncomfortable. One factor price noting, nonetheless: The computerized measurements are a bit annoying, as they aren’t introduced prematurely—or solely very briefly. The consequence: The measurement fails and have to be restarted. When completed, the watch shows the systolic and diastolic readings in addition to the heart beat instantly on the display. In random comparisons with a standard upper-arm blood strain monitor, the readings in our take a look at had been persistently very shut.

Ambulatory Blood Pressure Monitoring and Pre-/Post-Workout Readings

Beyond easy single measurements, the Huawei Watch D3 helps ambulatory blood strain monitoring (ABPM). According to worldwide hypertension tips, this methodology is taken into account one in all three acknowledged customary measurement modes as a result of it may detect phenomena similar to white-coat hypertension (elevated readings in a scientific setting however regular readings in on a regular basis life), masked hypertension, or nocturnal hypertension—situations {that a} single measurement within the physician’s workplace merely misses. Specifically, the watch mechanically measures blood strain as much as 20 occasions throughout the day and seven occasions at evening over a 24-hour interval and generates knowledgeable ABPM report based mostly on these readings. During testing, we ran the 24-hour mode a number of occasions; the nighttime measurements by no means as soon as woke us up, which is not any small feat given the inflatable air cuff on the wrist.

New to the D3 is the commercially licensed blood strain measurement earlier than and after train. According to Huawei’s personal comparability with its predecessor, this characteristic was nonetheless within the analysis section on the D2 and is being launched as an ordinary characteristic for the primary time with the D3, together with its personal CE-MDR certification particularly for this situation. The background: According to European skilled societies, an extreme blood strain response throughout bodily exertion is taken into account an impartial danger issue for subsequent hypertension, no matter resting blood strain. In wholesome people, systolic blood strain ought to drop by at the least 20 mmHg inside 5 to 10 minutes after train; if the worth stays elevated after half-hour, this will likely point out impaired vascular regulation. To assess this, the Watch D3 takes a measurement shortly earlier than the beginning of train as a baseline and one other inside a couple of minutes after the tip of train to file the height worth and restoration sample. We examined this characteristic after a number of operating periods. When the baseline worth was too excessive, the watch really actively suggested us towards intense coaching, relatively than merely displaying the measurement with out remark.

Health Monitoring: Health Glance, Health Insights, and More

In addition to blood strain measurement, Huawei has additionally considerably expanded the Watch D3’s different well being options. Health Glance offers a concise well being report inside 60 seconds and now covers 11 indicators as a substitute of the earlier 10—starting from common well-being to cardiovascular well being and girls’s well being metrics. During our testing, we received into the behavior of doing the Quick Check within the morning proper after waking up. The 60 seconds actually do fly by, and the report is simple to know relatively than overwhelming with uncooked information.

Health Insights, then again, analyzes information over an extended interval and, in keeping with the D3, not solely offers a multidimensional evaluation of significant indicators, train, and temper—as with the D2—but in addition dietary supplements this with new blood strain traits, a fast morning overview, a “Physical Readiness Score” indicating present bodily capability, and particular suggestions for motion.

The Huawei Watch D3 additionally goes a step additional with sleep evaluation: Instead of merely reporting a median sleep coronary heart charge variability—as with the D2—the brand new technology tracks sleep structure, together with a brand new metric for sleep stability, which supplied us with a considerably extra nuanced image of our nights over the course of the take a look at weeks than HRV values alone. In phrases of emotional well-being, the decision has elevated from 3 to 12 totally different emotional states, and Huawei has additionally built-in the beforehand separate stress monitoring into this dimension.

The well being bundle is rounded out by a medically licensed ECG, pulse wave evaluation for arrhythmia detection, SpO2 measurement, pores and skin temperature measurement, a menstrual cycle calendar, and guided respiratory workouts. This is an exceptionally complete bundle for a smartwatch, and the D3 persistently builds upon it relatively than reinventing it.

Sports, Phone, and Payment Features Put to the Test

Even past its core medical features, the Huawei Watch D3 is changing into extra appropriate for on a regular basis use. In phrases of sports activities modes, Huawei has expanded the D sequence’ already intensive repertoire to incorporate indoor snowboarding (with real-time information on distance, prime pace, common gradient, in addition to SpO2 and coaching depth insights), golf (with over 17,000 preloaded course maps, computerized distance measurement, a real-time first-person view of the inexperienced, and exact flag place), path operating (route navigation, map zoom, off-course alerts, and elevation profile and gradient information), and a compact mini-workout mode.

Another new characteristic for the D Series is Bluetooth calling: When paired with a smartphone, you may reply or reject incoming calls proper out of your wrist or test your name historical past. In our take a look at, the voice high quality by means of the built-in speaker was completely satisfactory for brief conversations on the go; nonetheless, for longer calls, we’d nonetheless advocate utilizing your smartphone or a headset.

Also new is the contactless cost characteristic by way of NFC utilizing Curve Pay, which incorporates helpful further options similar to a “Go Back in Time” possibility for correcting misguided funds, a central digital pockets for a number of playing cards, and a safety characteristic that mechanically requires you to re-enter your code if you take the watch off.

Connectivity, Battery Life, and Charging

In phrases of wi-fi capabilities, the Watch D3 options Bluetooth 6.0 (2.4 GHz, BR + BLE), built-in GPS, and NFC, whereas Wi-Fi remains to be not supported. The watch is thus clearly designed to pair with a smartphone relatively than set up standalone community connections, although we by no means discovered this to be a limitation in on a regular basis use.

The system is powered by a 540-mAh battery, for which Huawei specifies a typical runtime of as much as 6 days. In our take a look at, beneath regular use (with occasional particular person measurements, lively exercise monitoring, and the always-on show disabled), we achieved a strong 5 to six days. However, as quickly as we stored the 24-hour ambulatory blood strain monitoring characteristic constantly enabled, the battery life dropped way more shortly—to roughly two days per cost—a habits we’ve additionally noticed in the same kind in impartial assessments of its predecessor, the Watch D2. The watch totally charged in about 65 minutes utilizing the wi-fi charging cradle included within the field, which built-in effectively into our morning routine.

App Integration: Huawei Health

As regular, the Watch D3 is managed and supplied with further options by way of the Huawei Health app, which is appropriate with Android 8.0 and later and iOS 13.0 and later. We set it up by way of a compulsory firmware replace and a Huawei account.

It’s not a course of that’s performed in seconds, however it didn’t severely gradual us down both. In our take a look at, all options labored easily on Android; on iOS, nonetheless—as we’d already skilled with the D2—we needed to make some compromises in sure areas, similar to deeper app interplay and music management. Accordingly, Huawei explicitly recommends a Huawei smartphone for the total vary of options.

Huawei Watch D3 Review: Conclusion

With the Huawei Watch D3, Huawei continues to refine its distinctive promoting level within the smartwatch panorama: a medically licensed, oscillometric blood strain measurement that gives precise numbers relatively than mere development indicators and, with the first-ever licensed pre- and post-workout measurements in addition to the brand new context-sensitive reminders, takes issues a step additional than the already extremely rated Watch D2. During our several-week real-world take a look at, we had been notably impressed by how seamlessly the blood strain measurement now integrates into day by day life. Although the automated ABPM measurement begins too immediately and subsequently usually fails.

Combined with the noticeably thinner, lighter case, the bigger, brighter show, and the three sensible on a regular basis options—Family Health Community, NFC funds, and Bluetooth calling—this ends in a totally well-thought-out replace.

There are nonetheless some minor drawbacks concerning battery life beneath the total load of ambulatory monitoring, the iOS limitations acquainted from the D2, and the Family Health Community, which was not but totally activated on the watch itself on the time of testing. In our expertise, anybody in search of a severe, everyday-use blood strain smartwatch will discover that the D3 presently provides essentially the most mature bundle Huawei has ever delivered on this phase—and it’s unmatched within the wearable phase anyway.
