Huawei has launched the Watch D3, and it is one of those smartwatches where the most interesting thing isn’t the screen, the apps, or the number of workout modes. It is what happens underneath the strap.
The Huawei Watch D3 is built around blood pressure monitoring, giving it a very different purpose from a typical smartwatch. Huawei has also made the new model slimmer than its predecessor, which could make wearing this kind of health-focused watch feel a little less demanding. But how much has Huawei actually changed this time, and does the D3 make blood pressure monitoring more practical? We will find out in more detail in TFK’s review in a few weeks; for now, let’s look at Huawei’s launch info.
Huawei Watch D3 is officially here
The Huawei Watch D3 was officially announced on September 2, 2026, the third generation of Huawei’s wearables built around measuring blood pressure. Rather than treating blood pressure as one software feature among many, Huawei has built the whole watch around it. Ahead of the market launch, Huawei introduced the D3 at the ESC Congress 2026, the European Society of Cardiology’s annual gathering, to highlight its clinical grounding.
UK availability starts September 23, at £399.99, through all major retail outlets. The D3 is positioned differently from a typical fitness tracker.
The big change is 24-hour blood pressure monitoring
The main engineering advance in the Huawei Watch D3 is the inflatable mechanical cuff hidden inside the strap. This gives the watch full 24-hour ambulatory blood pressure monitoring (ABPM).
Rather than taking a single measurement once a week, the D3 takes automatic readings throughout the day and night. A spot check only gives you a small slice of information, and it can be skewed by white coat syndrome, the anxiety of being measured that pushes readings up. Ambulatory monitoring instead records your blood pressure curve across the day and how much it dips at night.
Huawei built this to follow clinical ABPM standards from the European Society of Hypertension, and you get a detailed cardiovascular trends report in the Huawei Health app.
Why the inflatable cuff still matters
Mainstream smartwatches from Apple or Google use optical sensors that rely on pulse wave analysis to estimate vascular changes. They measure blood volume fluctuations beneath the skin, and an algorithm estimates pressure trends from that.
The Huawei Watch D3 works differently: physical oscillometric detection. A micro-pump inflates an air bag inside the strap and occludes the wrist artery, taking an accurate pressure reading as it deflates. This removes the guesswork in optical estimation, though it still needs direct validation as a medical instrument. For a wider look at which wearables actually measure blood pressure rather than estimate it, see Blood Pressure Watches 2026: What Actually Works. The Wellue BPW1 review covers the same cuff-based approach in more detail.
Huawei adds pre- and post-exercise blood pressure monitoring
The feature most likely to interest endurance athletes and runners is pre- and post-exercise blood pressure monitoring.
You can record your starting vascular parameters before exercise and take a follow-up measurement within two minutes after. If your pre-exercise blood pressure is above the physiological thresholds, the watch sends an instant alert. Three cardiovascular activities are currently supported:
- Running
- Walking
- Cycling
Post-exercise blood pressure recovery gives athletes information about autonomic balance, arterial stiffness and general recovery. Huawei states this exercise-dependent blood pressure feature meets the relevant ISO standards.
The Watch D3 is much thinner than the D2
The Huawei Watch D3 is noticeably slimmer and more comfortable than its predecessor, the Watch D2. The size reduction changes it from an uncomfortable medical tool into a watch you would be willing to wear every day and night.
- Thinner body: 11.3mm thick, 2mm thinner than the D2’s 13.3mm.
- Slimmer band and cuff: the inflatable airbag is slimmer, and the strap is lighter, so there is no bulky, stiff band.
- Larger screen: a 1.92-inch screen at up to 3,000 nits brightness, twice as bright as the D2’s, and easy to read in direct sunlight.
- Different footprint: 46.5 x 41mm, versus the D2’s 48 x 38mm.
Having a watch that’s 2mm thinner makes a real difference to usability. The D3 measures your blood pressure while you sleep, and a thicker watch is more likely to catch on bed sheets and wake you. The thinner design and lighter band make overnight monitoring easier, and the extra brightness makes the screen readable outside on a run.

What else does the Huawei Watch D3 track?
Blood pressure is the headline feature, but the D3 also covers the usual ground:
- ECG: detects irregular heartbeats.
- Vitals: regular heart rate monitoring, SpO2 (blood oxygen saturation), and skin temperature.
- Sleep and recovery: deep sleep architecture, HRV (heart rate variability), and Huawei’s Physical Readiness Score.
- Health and Stress Glance: a multi-parameter stress reading in under a minute.
- Exercise mode: over 80 exercise modes, with automatic mode detection.
Huawei Watch D3 price and availability
The Huawei Watch D3 reaches the UK market on September 23, 2026, at £399.99, through the official Huawei Store, Amazon UK and other select UK retailers.
The Huawei Watch D3 is not currently available in the US.
Is the Huawei Watch D3 a serious fitness watch or a blood pressure monitor first?
For endurance athletes, the Huawei Watch D3 sits between the two worlds. It doesn’t try to replace a Garmin Forerunner or Polar Vantage for pace control, training load or breadcrumb navigation.
Instead, the D3 stays a health-monitoring device rather than a sports-performance one. The pre- and post-training monitoring mode makes it more useful for people who want to track their vascular reaction to cardiovascular load. The Watch D3 trades triathlon analytics for direct blood-pressure telemetry, a capability that’s still relatively uncommon among wearables.

Micro-pump inflatable cuff, 24-hour ambulatory blood pressure monitoring. Measures pressure directly, no optical calibration required.
Quick answers
When is the Huawei Watch D3 available and how much does it cost?
The Watch D3 becomes available in the UK on 23 September 2026 at £399.99, through the HUAWEI Store, Amazon UK and other select UK retailers.
How does the Huawei Watch D3 measure blood pressure?
A genuine inflatable cuff built into the strap compresses the wrist artery, using the same oscillometric principle as a clinical upper-arm monitor, rather than estimating blood pressure from an optical pulse waveform.
Is the Huawei Watch D3 available in the US?
No. The Watch D3 is not currently available in the US.
What's new on the Huawei Watch D3 versus the Watch D2?
The case drops to 11.3mm from 13.3mm, the screen grows to 1.92 inches at twice the brightness, and Huawei has added a dedicated pre- and post-exercise blood pressure mode.
