The HUAWEI WATCH D2 takes blood pressure readings using an inflatable airbag built into its strap, rather than estimating pressure optically. It can take individual readings or run a scheduled 24-hour ambulatory blood pressure monitoring (ABPM) plan. Before buying, check whether blood pressure features are supported in your country, whether the strap fits your wrist, and whether you can accept the much shorter battery life during ABPM. Huawei says its readings are for reference only, not for diagnosis or treatment.
How the WATCH D2 measures blood pressure
The WATCH D2 is Huawei’s blood-pressure-focused watch. Its strap contains a narrow, removable and replaceable airbag, 26.5 mm wide. The watch inflates the airbag and uses the oscillometric method to take a reading. That differs from a wearable that estimates blood pressure using optical sensors alone. Huawei’s product specifications describe the mechanism.

In addition to individual readings, the watch can run a preset 24-hour ABPM plan. It takes readings at scheduled intervals; it does not continuously measure blood pressure. The plan can produce whole-day, daytime and nighttime averages, along with a blood-pressure rhythm view. Huawei describes ABPM practice as a 24-hour schedule with readings every 15–30 minutes and at least 70% successful readings, including 20 daytime and 7 nighttime readings. That is guidance Huawei attributes to the European Society of Hypertension, not a guarantee that every watch plan or user will achieve those results.
What a 24-hour monitoring plan involves
Huawei’s support instructions say daytime readings are normally scheduled every 30 minutes, and nighttime readings are every 30 minutes by default. The watch inflates to take readings during sleep, so the routine is more involved than checking your pressure once and taking the watch off.

For daytime readings, keep your arm still and hold the watch at heart level. Huawei recommends choosing a less busy day for the plan. It also warns that ABPM affects sleep breathing awareness and heart-rate monitoring during sleep. Read Huawei’s ABPM instructions before deciding whether the schedule suits your day and night.
Check country availability and local feature support
Blood-pressure functions and medical-device status are not uniform worldwide. Huawei UK says the WATCH D2’s blood pressure and ABPM features have CE medical-device certification under EU Regulation 2017/745, but also says the watch is available only in selected European markets because national authorization or registration rules vary. Huawei’s global product page cautions that health indicators can differ by market.

| Strap | Huawei wrist circumference range |
|---|---|
| M | 13.0–16.0 cm |
| L | 16.1–21.0 cm |
Huawei warns that measurement accuracy may be affected on wrists below 13.0 cm or above 21.0 cm. If you are outside the listed ranges, do not assume the watch will fit or measure suitably; check with Huawei or an authorized local seller before buying. The ranges and fit warning appear on Huawei’s product page.
Plan for the battery tradeoff
Huawei claims up to six days of battery life under typical use, but up to one day with ABPM enabled. Its UK page specifies that the ABPM battery test used 15-minute intervals and a defined Huawei laboratory workload; actual runtime varies with use. Treat these as manufacturer test claims, not independently verified everyday results. If you plan to use the full monitoring schedule, expect to charge far more often than the typical-use figure suggests.

What is established about accuracy—and what is not
A PubMed-indexed study record describes an evaluation of the WATCH D2’s resting and ambulatory blood-pressure accuracy against a conventional ambulatory monitor, identified as the A&D TM-2430. The accessible record does not provide outcome data here, so it does not support quoting an accuracy percentage or claiming equivalence with that monitor.
Huawei has also published information about validation and a STRIDE BP listing for the earlier HUAWEI WATCH D, including a 2022 study involving 85 subjects. That evidence concerns the WATCH D, not the D2, and should not be treated as proof of D2 accuracy.
