HUAWEI WATCH D3 – Wrist Blood Pressure Monitoring Smartwatch with ECG and ABPM

Monitor blood-pressure trends more conveniently with the HUAWEI WATCH D3. Unlike ordinary smartwatches that estimate cardiovascular changes only through optical sensors, the Watch D3 uses an inflatable mechanical airbag built into its strap and an integrated pressure sensor to perform cuff-style wrist blood-pressure measurements.

It also supports 24-hour Ambulatory Blood Pressure Monitoring, ECG measurements, heart-rate and blood-oxygen monitoring, sleep analysis, Bluetooth calling, dual-band GPS and more than 100 workout modes. Its slim aluminum-alloy body and bright 1.92-inch AMOLED display make advanced health monitoring easier to incorporate into everyday life.

Mechanical Airbag Blood Pressure Measurement

The HUAWEI WATCH D3 uses the oscillometric measurement method, an inflatable mechanical airbag and a differential-pressure sensor to detect changes in pulse pressure at the wrist.

During a measurement, the airbag inside the strap inflates around the wrist in a manner similar to a compact blood-pressure cuff. This allows the watch to display systolic pressure, diastolic pressure and pulse information without requiring a separate upper-arm monitor for every routine reading.

Correct strap selection, fit and measurement posture are essential for obtaining reliable results.

24-Hour Ambulatory Blood Pressure Monitoring

A single blood-pressure reading provides information from only one moment. The Watch D3’s Ambulatory Blood Pressure Monitoring feature can automatically perform measurements throughout a scheduled 24-hour period, including while the wearer is asleep.

The resulting ABPM report can include:

• Average systolic and diastolic pressure

• Daytime blood-pressure averages

• Nighttime blood-pressure averages

• 24-hour blood-pressure averages

• Pulse information

• Blood-pressure patterns and trends

Reports can be viewed through the Huawei Health app and may be shared with a qualified healthcare professional.

ABPM availability, reporting functions and measurement intervals can vary according to country, device software and local regulatory approval.

Pre- and Post-Exercise Blood Pressure Insights

The HUAWEI WATCH D3 can provide supported reminders to take a blood-pressure measurement before or after exercise. A pre-exercise reading may help identify when blood pressure is unusually high, while a post-exercise reading can provide additional information about the body’s response to activity.

This feature supports selected indoor and outdoor activities, including walking, running and cycling. It must not be treated as a substitute for professional advice regarding safe exercise intensity.

Correct Blood Pressure Measurement Position

For a standard blood-pressure measurement:

1. Sit comfortably and relax your body.

2. Keep both feet flat on the floor without crossing your legs.

3. Support your elbow on a stable surface.

4. Keep your wrist and palm naturally extended.

5. Position the watch level with your heart.

6. Remain still and avoid speaking during measurement.

7. Do not press against or obstruct the inflatable airbag.

Incorrect posture, movement, talking, an unsuitable strap size or a wet airbag can affect measurement accuracy.

Select the Correct Strap Size

The Watch D3 supports wrist circumferences from approximately 130mm to 210mm:

• M-size airbag strap: 130–160mm

• L-size airbag strap: 161–210mm

Use the included wrist-circumference ruler to select the appropriate airbag and strap. Blood-pressure accuracy may be affected if the wearer’s wrist is smaller than 130mm or larger than 210mm.

ECG Measurement from the Wrist

The built-in ECG sensor can produce an electrocardiogram report after the user holds the side electrode for approximately 30 seconds. The watch also supports pulse-wave arrhythmia analysis using its PPG sensor and may provide alerts relating to potential atrial-fibrillation risks.

ECG and arrhythmia features are available only in supported countries and regions. Results should not be used independently to diagnose a condition or adjust medication.

All-Round Health Monitoring

In addition to blood pressure and ECG, the Huawei Watch D3 supports a range of wellness measurements:

• Continuous heart-rate monitoring

• Blood-oxygen monitoring

• Heart-rate-variability insights

• Sleep monitoring with HUAWEI TruSleep

• Stress-related information

• Emotional-wellbeing insights

• Activity and calorie tracking

• Physical Readiness Score

• Health Glance reports in supported regions

The Physical Readiness feature combines factors such as sleep, heart rate, HRV, stress and recent activity to provide daily recovery guidance.

Availability of individual measurements and reports depends on country, Huawei Health version, phone platform and watch software.

Slimmer Design for Everyday Wear

The HUAWEI WATCH D3 measures approximately 11.3mm at the thinnest part of its body, excluding the sensor area. Its aluminum-alloy case weighs around 40g without the strap.

A narrower inflatable airbag and redesigned strap improve comfort during daytime wear and overnight ABPM sessions. Available finishes may include:

• Mocha Gold with a sand composite-leather strap

• Gold or Light Gold with a white composite-leather strap

• Black with a black HNBR strap

Color names and combinations can vary by market.

Large 1.92-Inch AMOLED Display

The 1.92-inch AMOLED display provides a resolution of 408 × 480 pixels at approximately 328 PPI. Peak brightness can reach up to 3,000 nits under Huawei’s specified laboratory conditions, helping health information, calls and notifications remain visible outdoors.

A rotating crown and separate function/ECG button provide convenient control without relying exclusively on the touchscreen.

Bluetooth Calling and Everyday Features

When connected to a compatible smartphone, the Watch D3 allows users to answer or reject Bluetooth calls and view recent call information from the wrist.

Other supported functions can include:

• Phone notifications

• Calendar access

• Notes

• Weather information

• Alarms and reminders

• Torch function

• NFC services in supported regions

The watch does not contain a standalone SIM or eSIM. Bluetooth calling requires connection to a compatible smartphone.

More Than 100 Workout Modes

Track walking, running, cycling, golf, snow sports and other activities using more than 100 workout modes. Built-in mini-workouts can also provide short guided movements for users who want to stay active during work or study breaks.

The watch includes dual-band, multi-system GNSS support for recording compatible outdoor routes without relying entirely on the phone’s location signal.

Up to Six Days of Battery Life

Huawei rates the Watch D3 for up to six days of battery life with typical use. When 24-hour ABPM is enabled with frequent automatic measurements, battery life can be approximately one day.

Battery performance depends on:

• ABPM measurement frequency

• Manual blood-pressure and ECG measurements

• Bluetooth calling

• Display brightness and screen-on time

• Always-on health monitoring

• Notifications

• Workout and GPS usage

• Temperature and software configuration

The supplied wireless charger can fully charge the watch in approximately 75 minutes under supported conditions.
