The Huawei Watch D3 stands out from most rival smartwatches with a feature they rarely offer: mechanical blood pressure measurement. Under the strap sits a small inflatable cuff, driven by a micro-pump, that applies the pressure needed for a reading. It is not an optical estimate like on most watches, but a measurement that requires real contact with the wrist.
The price is 449 euros. The strap is wider and thicker than usual because it houses the air chamber: 25.5 mm wide, against 26.5 mm for the Watch D2, and 7.5 grams lighter. The case weighs 40 grams. The strap closes with a clasp similar to that of a traditional watch and must be sized on first use, choosing the medium or large size. The process takes about five minutes, and the fit affects measurement accuracy.

The most significant limit concerns water. Huawei says the Watch D3 should not get wet: no IP rating is listed, and if it gets wet the company advises drying it completely before taking a blood pressure reading. The air chamber is also a consumable part that will eventually need replacing through Huawei partners or an authorized service centre, because it is a certified medical component.
Battery life beats expectations. Huawei claims six days with typical use, but in Android Authority's test the watch ran for more than 11 days. The figure assumes most sensors are active but not continuous automatic blood pressure and skin temperature readings, which are the most power-hungry. With everything enabled, battery life approaches the six days claimed. For comparison, the Garmin Fenix 9 Pro Solar, tested by the same outlet, lasts eight to nine days with LTE and GPS on, though it gets some help from solar power.
The 1.92-inch AMOLED screen, with 408 x 480 resolution and a peak brightness of 3,000 nits, is smooth and responsive. Everyday functions are the expected ones: notifications, weather, timers and calls. The Watch D3 works with Android and iOS but does not include Google services, a known limit of the Huawei range.
Overall the device targets people who want continuous blood pressure monitoring without extra equipment, more than those seeking a waterproof sports watch. Owners of the Watch D2 get essentially the same blood pressure technology, as other reviews also point out.
