Expert opinion
The Watch D2’s real distinction against every optical blood-pressure watch on the market is mechanical, not algorithmic: a genuine inflatable cuff built into the strap measures pressure by compressing the wrist artery, the same oscillometric principle used by a clinical upper-arm monitor, rather than estimating it from a pulse waveform. Huawei quotes six days of typical battery life, falling to a single day with 24-hour ambulatory monitoring enabled, a real cost for continuous clinical-style data rather than a single daily reading. The design carries the bulk an inflatable mechanism requires, and the watch trails Huawei’s mainstream models on smart features and app support.
Huawei Watch D2
Micro-pump inflatable cuff, 24-hour ambulatory blood pressure monitoring. Measures pressure directly, no optical calibration required.
What’s new versus the Watch D
Pending: a full comparison requires the original Watch D’s official spec sheet, not yet in hand.

Battery life
Huawei’s typical-use figure assumes six blood pressure measurements and five ECG measurements a day. Enabling 24-hour ambulatory blood pressure monitoring (ABPM), which takes a reading roughly every 15 minutes around the clock, cuts battery life sharply.
| Mode | Battery life |
|---|---|
| Typical use | Up to 6 days |
| ABPM enabled (15-minute intervals) | Up to 1 day |
