Huawei Watch D2 (Luca-B19), Black

The HUAWEI WATCH D2 is a smartwatch designed for ambulatory blood pressure monitoring on the wrist using the oscillometric method with TruSense system. It combines 24-hour blood pressure tracking, an ECG app, and pulse wave analysis with a 1.82-inch AMOLED display offering 1500 nits peak brightness. Key Benefits at a Glance Wrist-based ABPM: 24-hour blood pressure monitoring at 15–30-minute intervals ECG & Pulse Wave Analysis: 30-second ECG with PPG sensor and atrial fibrillation detection Health Glance: 10 key health indicators at a glance 80+ Workout Modes: automatic recognition of 6 common activities Cross-platform: compatible with iOS 13.0 and later, and Android 8.0 and later Blood Pressure Measurement & Cardiovascular Monitoring The WATCH D2 performs ambulatory blood pressure monitoring on the wrist using the oscillometric method with the TruSense system. For 24-hour monitoring, the device recommends measurement intervals of 15 to 30 minutes, with at least 70% of readings successfully completed—including 20 during the day and 7 at night. The ECG app captures a beat-by-beat ECG in 30 seconds. Pulse wave analysis uses a PPG sensor to detect atrial fibrillation and issues relevant alerts. Health Features & Sensors Health Glance consolidates 10 key health indicators, including an emotional health score. SpO₂ measurement runs continuously at rest, while heart rate monitoring operates 24/7 with an intelligent tracking mode. The stress monitor takes readings at rest and offers breathing exercises. Skin temperature is recorded as an estimated value of wrist skin. Comprehensive sleep monitoring analyzes HRV, sleep heart rate, respiratory rate, and SpO₂, while detecting abnormal breathing. Automatic activity recognition covers 6 common activities across over 80 workout modes. Display & Design The 1.82-inch AMOLED display delivers a peak brightness of 1500 nits. The mechanical air cushion is ultra-slim at 26.5 mm. The watch is IPX8-rated per IEC 60529:2013 and withstands static pressure equivalent to 1.5 meters for 30 minutes. The medium (M) band fits wrist circumferences of 13.0 to 16.0 cm, while the large (L) band fits 16.1 to 21.0 cm. Battery Life & Connectivity Under typical use, battery life lasts up to 6 days. With ABPM enabled, runtime is reduced to up to one day. The watch supports Bluetooth calls and is compatible with iOS 13.0 and later, as well as Android 8.0 and later. GNSS positioning enables precise location tracking.
