Huawei has expanded its health-focused wearable lineup with the HUAWEI WATCH D3, a new smartwatch designed around blood pressure monitoring rather than conventional smartwatch features alone. The company has introduced the D3 alongside its latest Watch 6 and Watch GT 7 series, but the D3 takes a more specialized approach by combining smartwatch functions with an inflatable blood-pressure-measuring airbag in its strap.
The new model keeps the general design language of the Watch D2 while becoming slimmer and lighter. It also brings a larger, brighter display, updated Bluetooth connectivity and new pre- and post-exercise blood pressure measurements. Huawei lists the Watch D3 at £399.99 in the UK, with availability beginning September 23.

Design & Build
The Watch D3 retains the rectangular design associated with Huawei’s D-series health watches, but the company has made the body slimmer. It measures 11.3mm thick and weighs approximately 40g without the strap. Huawei says the new design reduces overall weight and thickness compared with the Watch D2, while the narrower airbag is intended to make the watch more comfortable to wear.
The case uses aluminum alloy and comes in Gold, Light Gold and Black configurations, with corresponding composite-leather or HNBR straps depending on the version. The watch also includes a rotating crown and a function/ECG button.
The most unusual part remains the strap. Instead of relying only on optical sensors, the D3 uses a mechanical airbag and pressure sensor to measure blood pressure using the oscillometric method.
Display
Huawei has upgraded the screen to a 1.92-inch AMOLED panel with a 408 × 480-pixel resolution. The display can reach 3,000 nits peak brightness, double the 1,500-nit peak brightness quoted for the Watch D2 in the supplied source.
That higher brightness should make the D3 considerably easier to read outdoors, particularly when checking health readings or notifications in bright sunlight. The larger screen also gives the watch more room for health charts and other information.
However, the 3,000-nit figure is a peak measurement rather than a brightness level the display will maintain constantly. Huawei specifies that its peak figure is measured under particular laboratory conditions.
Health & Fitness Features
Blood pressure monitoring is the Watch D3’s main reason for existing. Huawei supports 24-hour ambulatory blood pressure monitoring, allowing measurements to be taken automatically at intervals throughout the day and night. The resulting data can be reviewed through the Huawei Health app and used to generate ABPM reports.
A new addition is pre- and post-exercise blood pressure measurement. The watch can measure blood pressure before and after supported workouts, giving users additional context around exercise intensity.
The D3 also includes ECG, optical heart-rate monitoring, HRV, sleep tracking and pulse-wave arrhythmia analysis. Huawei’s Health Glance feature can provide a report covering 11 health indicators, although availability of individual health features varies by market.
Huawei says the Watch D3 is CE-MDR-certified as a medical device. However, the company also clearly states that readings should not be used as a substitute for medical diagnosis or treatment. That distinction is important for anyone considering the watch specifically for blood-pressure management.
Smart Features & Connectivity
The Watch D3 isn’t limited to health tracking. It supports Bluetooth calling, notifications, more than 100 workout modes and NFC functionality, although NFC services can vary depending on the country.
Huawei also supports both Android and iOS devices. The official specification page lists Android 8.0 or later and iOS 13.0 or later, while Huawei’s feature documentation notes that some functions have additional software or regional requirements.
Battery & Charging
The Watch D3 has a 540mAh battery and supports wireless charging. Huawei rates it for up to six days of typical use under its specified testing conditions.
There is an important catch for the watch’s headline health feature: with 24-hour ABPM enabled, Huawei rates battery life at up to one day. Users who rely heavily on continuous blood-pressure monitoring will therefore need to charge considerably more frequently.
Price & Availability
The Huawei Watch D3 is priced at £399.99 in the UK and is scheduled to go on sale from September 23, 2026. Independent launch coverage also reports Huawei’s UK Store, Amazon and selected retailers as sales channels.
- Huawei Watch D3 – £399.99 (Approx. Rs.50974.45)
- Colour Options :- Mocha Gold and Black
Competition & Alternatives
The Watch D3 occupies a different position from mainstream smartwatches because its defining feature is cuff-style blood-pressure measurement.
| Alternative | Why Consider It? | Why Choose Watch D3 Instead? |
|---|---|---|
| Huawei Watch 6 | Broader smartwatch feature set | D3 focuses much more heavily on blood pressure |
| Huawei Watch GT 7 | Longer battery-oriented wearable experience | D3 offers dedicated blood-pressure monitoring |
| Samsung Galaxy Watch series | Strong mainstream smartwatch ecosystem | D3’s mechanical BP-monitoring approach is more specialized |
The biggest reason to choose the D3 isn’t necessarily its display or battery. It is the combination of 24-hour blood-pressure monitoring, ECG and broader health tracking in a wearable that Huawei has specifically positioned around health management.
Final Verdict: Should You Buy It?
The Huawei Watch D3 makes the most sense for people who specifically want advanced blood-pressure monitoring alongside smartwatch and fitness features. Its mechanical airbag system, 24-hour ABPM capability and pre- and post-exercise measurements give it a clear identity that most mainstream smartwatches don’t match in the same way.
The brighter 1.92-inch display, slimmer body and improved health features also make it a more polished wearable than the previous generation.
However, £399.99 is a significant price, and the biggest compromise is battery life when continuous ABPM is enabled. Buyers who primarily want notifications, workouts and general health tracking may find a conventional smartwatch more suitable.
Best for: Users who prioritize blood-pressure monitoring and broader health tracking.
Consider alternatives if: You mainly want a general-purpose smartwatch, longer battery life or a lower price.
Bottom line: The Huawei Watch D3 is a specialized health-focused smartwatch rather than a conventional smartwatch with a few health features added. Its biggest advantage is the combination of 24-hour blood-pressure monitoring and a more refined wearable design.
