Huawei needed three generations to turn its fullest health-tracking wearable from a thick, awkward block with a wide, sweaty strap into a watch meant for everyday wear. Reviewer Jānis Vēvers, writing for TVNET on 19 October 2026, says the new Watch D3 looks like a modern smartwatch with a wide, bright square AMOLED screen. The piece was produced in cooperation with Huawei Latvia.
The strap is 7.5 grams lighter than on the second-generation device and hides an inflatable cuff. The cuff briefly compresses blood vessels to measure blood pressure, in the same way as a monitor in a family doctor’s office. The metal case is 11.3 millimetres thick, in line with Huawei’s and rivals’ slimmest watches. Its thin shape recalls the Watch Fit 5, though Vēvers describes the D3 as a higher-level device.
The built-in air cuff is narrower and more compact than in earlier generations, and made from more breathable, skin-friendlier materials. Vēvers writes that it no longer gets in the way of daily movement, does not rub, and lets the skin breathe, which matters if the watch is worn around the clock. The 1.92-inch display is paired with 3000-nit brightness so health data, charts and notifications stay readable in strong sun or while walking.
Blood pressure remains the main feature. The user sits in a chair, raises the arm to heart height and stays still for a few seconds. The cuff inflates, then releases air and records systolic and diastolic pressure. A 24-hour mode takes automatic readings at set intervals. By day a light vibration prompts the correct posture; at night readings can run in the background without disturbing sleep. The watch can also compare readings just before and after sport, including running, strength training or a brisk walk.
Vēvers notes that doctors may argue such devices can mislead if the wearer moves too much or the strap is not tight enough. The watch flags many failed readings and leaves them out of the statistics. On test days he regularly compared the watch with a certified upper-arm medical tonometer. Differences stayed within 3 to 5 units. He also points out that the Watch D3 is certified in the European Union as a medical device.
Beyond blood pressure, the watch can record an electrocardiogram and, within seconds, flag a heart-rhythm disturbance or arrhythmia. A one-touch health check, completed in under a minute, measures pulse, blood oxygen (SpO2), stress, skin temperature and vascular elasticity, then combines them in one report. Sleep tracking records sleep stages and overnight breathing stability and offers advice on rest. If stress rises during the day, the watch can guide breathing exercises.
A microphone and speaker support voice calls over Bluetooth with a phone. The screen shows notifications and messages, and replies can use prepared short phrases. It tracks load in more than 100 sports, draws a training route on a map, and works with Android and iOS phones. Curve Pay lets the wearer pay by holding the watch near a contactless terminal, as with a bank card.
With health tracking in active use, including regular blood-pressure checks, sleep analysis and calls, Vēvers reports about five to six days from a full charge. Measuring blood pressure less often can stretch that toward a week. A full charge takes 75 minutes.
He contrasts this with Huawei’s first European blood-pressure watch with a real inflatable cuff, shown four years earlier, which he describes as bulky and heavy. After a couple of weeks with the D3, he says it can serve as a daily watch for activity, health, messages and calls. It comes in white, black or mocha gold. At €449 he calls it a useful buy for anyone who wants or needs to follow blood pressure and heart health without changing daily habits. During an introductory offer, the purchase also includes another health device, the Huawei Scale 3 smart scales.
