Huawei Watch D3 Review: A Smartwatch With a Real BP Cuff

Design and display

The case is 11.3 mm thick, down from 13.3 mm on the previous generation, and weighs about 40 grams without the strap. The 46.5 x 41 mm aluminium case comes in black, white and mocha gold. Two strap sizes (M for 130 to 160 mm wrists, L for 161 to 210 mm) are included, along with an induction charging cable and a wrist-measuring guide.

The 1.92-inch Amoled screen (408 x 480 pixels) reaches 3,000 nits and stays readable in direct sunlight. The watch runs HarmonyOS, which feels fluid and intuitive, with health shortcuts at the top by default.

Health features

Beyond spot checks, the watch supports 24-hour ambulatory blood pressure monitoring (MAPA), plus ECG, sleep tracking, and readings before and after exercise. GPS and heart-rate tracking performed well. The Huawei Health app, on Android 8.0 or later and iOS 13.0 or later, is clear and detailed, and its Health Community feature alerts you to anomalies in relatives' data.

Weaknesses

The case is still thick because of the pump. The strap is not very breathable, and the long-term durability of the airbag is a question, although a second strap and two years of replacement service are included. The IP68 rating does not cover showers or pools.

In France, NFC payment works only through Curve, and the app store lacks almost all major third-party apps. The MultiPass programme adds several free months of services such as Komoot or Headspace.

The D3 suits users who want reliable blood pressure tracking on the wrist and can accept a chunky design and a limited app ecosystem.
