It pumps up. The Huawei Watch D focuses on one feature: blood pressure measurement. The smartwatch is the first of its kind. It pumps up the wristband and measures the blood pressure without calibration or other accessories. Our test clarifies whether that works and what else the watch can do.

The Huawei Watch D focuses on the blood pressure function
The Huawei Watch D is a world-first watch that can measure blood pressure without the need for prior or regular calibration. Because the watch is the first of its kind, this function is always at the center.
The Huawei Watch D is only available in a variant with a gray case and black rubber strap. Huawei does not offer an LTE variant.

The Watch D’s casing is rectangular and made of fiberglass-reinforced plastic. The glass above the display does not have any curvature. Two buttons are installed on the right and have a good pressure point. The lower button has a very good fit, whereas the upper one has a slight play.
A microphone is installed underneath the keys and on the opposite side. However, Watch D users will have to do without a speaker.
The band is 30 millimeters wide and has two layers. Huawei uses fluoroelastomer on the outside. The manufacturer uses a light fabric on the inside. The air chamber, which is needed for blood pressure measurement, is located between the two layers. The fabric is loose and can wrinkle depending on the wearing situation, which can lead to pressure points.
Huawei relies on a quick-release fastener on the wristband, which can be adjusted to the wrist’s thickness with fine grids. The scope of delivery includes straps in two different sizes. The straps can be exchanged without tools. However, there are no other bands on the open market due to the special width and especially the pump function. Huawei itself also only offers one band.
The watch without the band weighs just under 41 grams – as promised by Huawei. With the band size L it is 91 grams.
