uawei has rolled out the third generation of its dedicated blood pressure smartwatch, the Watch D3. While most fitness trackers estimate blood pressure via optical sensors and vascular pulse wave algorithms, Huawei sticks to physical mechanics: the strap houses an actual micropump and an inflatable cuff. The device adheres to strict Ambulatory Blood Pressure Monitoring (ABPM) standards, physically compressing the artery to deliver reliable readings instead of algorithmic guesswork.
On the wrist, the new model feels noticeably sleeker than its predecessor. Huawei shaved the profile down to 46.5 × 38.8 × 11.4 mm (down from the Watch D2's 13.3 mm thickness) while keeping the weight at 40 grams. The AMOLED display grew to 1.92 inches from 1.82 inches. Since resolution stays unchanged at 409 × 480 pixels, pixel density drops slightly to 328 ppi, though the difference is imperceptible in daily use. A 540 mAh battery delivers up to six days of battery life. Connectivity includes Bluetooth 6.0 and NFC with Curve Pay support, and the companion app works on Android 8+ or iOS 13+.
In Europe, Huawei has priced the device at €450. Early promotional discounts include €20 off with a promo code, a €100 trade-in credit for previous Watch D owners, and bundled FreeBuds SE4 earbuds or a Scale 3 body scale. Still, buyers should weigh their actual needs before ordering. For individuals managing diagnosed hypertension, this remains one of the few truly compact tools that replace cumbersome medical gear. For everyday users without medical indications, paying premium prices to be woken up at night by an inflating cuff is a tough sell.
