Most smartwatches wave at blood pressure monitoring from a distance, using optical sensors to estimate trends without ever touching the hard part. The Huawei Watch D3 doesn't do that. It packs a miniature pump and an inflatable airbag directly into its strap, squeezing your wrist the same way a doctor's cuff squeezes your arm. The result is medically certified blood pressure readings you can take on demand or collect automatically over 24 hours, even while you sleep.
That's a fundamentally different approach than what Apple, Google, or Samsung offer. The Watch D3 holds CE certification under the EU Medical Device Regulation for its blood pressure functionality, which means it meets regulatory standards as an actual medical device, not just a wellness gadget. The inflatable cuff measures systolic and diastolic pressure using physical compression and a high-precision sensor, not algorithmic guesswork.
Huawei launched the Watch D3 in early September, and it's now available in the UK for £399.99 and across Europe for €449, roughly $535. The watch itself is 11.3mm thick and weighs 40 grams, noticeably slimmer than the previous Watch D2 despite housing the same airbag mechanism. The strap measures 25.5mm wide, down from 26.5mm on the older model. It comes in Black, White, and Mocha Gold finishes.
The core feature here is ambulatory blood pressure monitoring, which tracks readings throughout the day and night without you having to remember to manually take them. The watch can also prompt you to measure before and after exercise, or when it detects environmental changes like temperature drops that might affect your blood pressure. Beyond the cuff, it includes standard smartwatch features like workout tracking across 100-plus modes, sleep monitoring, Bluetooth calls, and NFC payments.
The catches are predictable. You can't wear it in the shower or while swimming despite its IP68 rating. The strap doesn't breathe well, which matters when you're wearing something 24 hours a day. There's essentially no third-party app ecosystem. And if you're in the US, you're out of luck entirely due to existing restrictions on Huawei products.
But if you actually need continuous blood pressure data and you're in a market where Huawei operates, the Watch D3 is doing something no other consumer smartwatch is willing to attempt. It's less a watch that happens to measure blood pressure and more a blood pressure monitor you can wear as a watch. That narrow focus is exactly what makes it interesting.
