🩺 Real Airbag Blood Pressure Measurement — Not an Optical Estimate

Most smartwatches estimate blood pressure using an optical sensor (PPG) — a method known for limited accuracy. The WATCH D2 is fundamentally different: inside the strap sits a 26.5 mm inflatable airbag that physically inflates around your wrist, driven by a micro pump and read by a high-precision pressure sensor. That's genuine oscillometric measurement — the same principle as the cuff at your doctor's office. A reading completes in under a minute.

📊 24-Hour Ambulatory Blood Pressure Monitoring (ABPM)

This is the capability no other smartwatch offers:

1. Automatic readings at set intervals (every 30 minutes by default) throughout the day
2. Automatic night-time readings while you sleep — no waking, no posture adjustment
3. Analysis of average blood pressure for the full day, daytime, and night-time separately
4. BP rhythm analysis across the 24-hour period
5. A complete report you can print or save from the HUAWEI Health app and share with your doctor

Why does this matter? Clinic readings are distorted by the white-coat effect, and one or two home readings miss overnight spikes entirely. ABPM is the gold standard clinically recommended for accurate hypertension assessment — and until now it required a bulky Holter device strapped to your belt for a full day.

❤️ Certified ECG

An electrocardiogram reading in 30 seconds, with analysis flagging signs of irregular heart rhythm and atrial fibrillation (AF).

🔬 One-Click Micro Health Check — 13 Indicators

The One-click Micro Health Check generates a single report covering 13 health indicators including: blood pressure · heart rate · blood oxygen · pulse wave analysis · sleep apnoea detection · high blood glucose risk assessment · and more.

😴 Comprehensive All-Day Health Monitoring

1. 24/7 heart rate with alerts
2. Blood oxygen (SpO₂)
3. Stress levels
4. Sleep tracking via TruSleep™ with sleep breathing awareness
5. Skin temperature and cycle tracking

🪶 13.3 mm and 40 g — Slim Despite the Internal Pump

A device containing an air pump, a pressure sensor, and an inflatable bladder measures 13.3 mm thick at 40 g. Compared with a palm-sized Holter monitor clipped to your belt, the difference is enormous. You can wear this to work and to meetings and nobody will register it as a medical device — and the black finish reinforces that, reading as an ordinary formal watch.

✨ 1.82" AMOLED · 📞 Bluetooth Calling · 🏃 80+ Workout Modes

A large AMOLED panel at 480 × 408 and 347 ppi — readings and charts are clear without straining your eyes, which matters especially for older users. A built-in speaker and microphone let you answer calls from the watch, and over 80 workout modes are backed by advanced GNSS positioning.

🔋 Battery Sized for a Full ABPM Plan · ⌚ Two Strap Sizes

The battery lasts several days in normal use and covers a full day with an ABPM plan running. Charging is wireless. The strap comes in M (130–160 mm) and L (161–210 mm) sizes with a Quick Release button.

🛡️ 6 Months of HUAWEI Care+ — Included

Extended protection covering accidental damage for six months. (Plan terms apply; confirm activation details when ordering.)
