Huawei Watch D3

DESCRIPTION.

The Huawei Watch D3 is a health-focused smartwatch featuring a built-in mechanical airbag cuff inside its strap for medical-grade wrist blood pressure monitoring. Unlike standard optical smartwatches that only estimate blood pressure, it uses an internal micro-pump and an ultra-narrow 25.5 mm airbag to measure pressure directly using the oscillometric method without needing manual calibration. Certified as a medical device, the watch supports 24-hour ambulatory blood pressure monitoring that inflates automatically throughout the day and night, alongside a new pre- and post-workout tracking mode. Beyond blood pressure, it delivers comprehensive heart and wellness insights through an ECG sensor, pulse wave arrhythmia analysis, arterial stiffness detection, blood oxygen monitoring, skin temperature tracking, and a 60-second Health Glance checkup.

In terms of design and performance, the Watch D3 features a lightweight 40-gram aluminum alloy case that measures just 11.3 mm thick, making it noticeably slimmer than its predecessor. It sports a crisp 1.92-inch AMOLED display with 3,000 nits of peak brightness, a rotating crown, and a dedicated ECG button. The watch is compatible with both Android and iOS devices, offering over 100 workout modes, dual-band GPS, and Bluetooth calling. Its 540 mAh battery lasts up to six days under typical daily use—or about one day when continuous 24-hour blood pressure monitoring is active—and while it carries an IP68 rating for sweat and dust resistance, the mechanical airbag system means it should not be worn while swimming or showering.
