Huawei Watch D2 (Luca-B29), Blue

The Huawei Watch D2 is a smartwatch with 24-hour blood pressure monitoring that measures blood pressure at the wrist using the oscillometric method with the TruSense system. It is designed for users who need continuous health monitoring with ECG, SpO₂, and sleep analysis in a single wearable device. Key Benefits at a Glance Medical-grade blood pressure measurement: Oscillometric method with TruSense system for single and 24-hour measurements IPX8 water resistance: Up to 1.5 meters of static water pressure for 30 minutes per IEC 60529:2013 Comprehensive health monitoring: 10 key metrics via Health Glance, including emotional health 80+ sports modes: Automatic detection of six common activities with GNSS tracking Blood Pressure Monitoring The Huawei Watch D2 measures blood pressure at the wrist using the oscillometric method with the TruSense system. For 24-hour ambulatory blood pressure monitoring, measurement intervals of 15 to 30 minutes are recommended, as suggested by the ESH. At least 70% of measurements should be successful, including 20 daytime and 7 nighttime readings. The recommended wrist circumference for accurate blood pressure measurements is between 13.0 and 21.0 cm. A 26.5 mm ultra-slim mechanical air cushion is integrated into the watch, enabling wrist-based blood pressure measurement. Guidelines are provided for standard single measurements and ABPM posture. Health Monitoring Health Glance tracks 10 key health metrics, including an emotional health score. The ECG is measured in 30 seconds. The Pulse Wave Arrhythmia Analysis uses a PPG sensor and issues alerts for atrial fibrillation. Sleep monitoring tracks heart rate variability (HRV), sleep heart rate, respiratory rate, SpO₂, and abnormal breathing during sleep. SpO₂ measurement is performed automatically at rest. Heart rate monitoring adjusts the measurement frequency in smart tracking mode based on activity level. Stress monitoring includes calming breathing exercises. Skin temperature is recorded as a wrist skin temperature estimate for healthy individuals over 18 years old. Display The 1.82-inch AMOLED display achieves a peak brightness of 1500 nits, ensuring clear visibility of health data. The screen remains easily readable even in bright lighting conditions. Battery Life With typical use, the battery lasts up to 6 days. When the ABPM function is enabled, battery life is reduced to up to 1 day. Compatibility and Connectivity The Huawei Watch D2 is compatible with iOS 13.0 and Android 8.0 or later and requires the HUAWEI Health app. Bluetooth calls are supported directly from the wrist. GNSS tracking is available for workouts. Sports and Activity The watch offers over 80 sports modes with automatic detection of six common activities.
