Huawei Watch D2 (Luca-B29), Blue

The Huawei Watch D2 is a medical wearable featuring 24-hour ambulatory blood pressure monitoring (ABPM) and comprehensive health tracking via the HUAWEI TruSense system. It is designed for users who require continuous, certified vital-sign monitoring on the wrist.

Key Benefits at a Glance
Medical-grade blood pressure monitoring: oscillometric method with TruSense system and high-precision pressure sensor
24-hour ABPM: automatic measurements at 15–30-minute intervals throughout the day
Health Glance: up to 10 insightful health indicators, including emotional well-being
Heart rhythm analysis: PPG-sensor-based atrial fibrillation detection with alerts
80+ workout modes: automatic recognition of six common activities
AMOLED display: 1.82 inches with 1500 nits peak brightness
Battery life: up to 6 days with typical use

Blood Pressure & Cardiovascular Monitoring
The Huawei Watch D2 measures blood pressure using the oscillometric method, employing a high-precision pressure sensor combined with the HUAWEI TruSense system. Ambulatory blood pressure monitoring (ABPM) performs 24-hour measurements at intervals of 15 to 30 minutes, requiring at least 70% successful readings, including 20 during the day and 7 at night. A 26.5 mm ultra-slim mechanical air cushion enables pressure measurement directly on the wrist.
Pulse Wave Arrhythmia Analysis relies on a PPG sensor and issues alerts for detected atrial fibrillation. An ECG is recorded in 30 seconds. Heart rate monitoring operates in an intelligent tracking mode that adjusts measurement frequency based on activity level.

Health Indicators & Sleep Analysis
Health Glance consolidates up to 10 insightful health indicators, including a value for emotional well-being. The wearable monitors respiratory, nervous, and endocrine systems. SpO₂ measurement occurs automatically at rest, as does stress monitoring, which independently measures and logs stress levels. Skin temperature is recorded as an estimate of wrist skin temperature.
Sleep monitoring tracks average heart rate variability (HRV), sleep efficiency, respiratory rate, SpO₂, and abnormal breathing during sleep. Stress monitoring automatically measures and logs data while at rest.

Display, Design & Battery
The 1.82-inch AMOLED display achieves a peak brightness of 1500 nits. The wristband is available in two sizes: size M for wrist circumferences of 13.0 to 16.0 cm and size L for 16.1 to 21.0 cm. The watch comes in blue, gold, and black.
With typical use, battery life lasts up to 6 days. When ambulatory blood pressure monitoring (ABPM) is enabled, battery life is reduced to up to one day. GNSS positioning enables precise location tracking.

Compatibility & Water Resistance
The Huawei Watch D2 is compatible with iOS and Android, requiring at least Android 8.0 or iOS 13.0 and the HUAWEI Health app. With an IPX8 rating per IEC 60529:2013, the watch withstands static water pressure of up to 1.5 meters for 30 minutes.
