Huawei Watch D2 (Luca-B10L), White

The Huawei Watch D2 is a smartwatch designed as a medical device, featuring 24-hour ambulatory blood pressure monitoring as its core function. It uses the oscillometric method with a slim 26.5 mm mechanical air cuff and the TruSense system. Key Benefits at a Glance 24-Hour Blood Pressure Monitoring: Automatic measurements at 15–30-minute intervals throughout the day Health Glance: 10 health indicators, including emotional health, in a single overview 30-Second ECG: Beat-by-beat electrocardiogram measurement directly from the wrist Atrial Fibrillation Detection: PPG sensor-based pulse wave arrhythmia analysis with alerts 80+ Sports Modes: Automatic detection of 6 common activities IPX8 Water Resistance: Withstands static water pressure up to 1.5 meters for 30 minutes per IEC 60529:2013 Up to 6 Days Battery Life: Under typical use without the ABPM feature enabled Blood Pressure Measurement & ABPM The Huawei Watch D2 measures blood pressure using the oscillometric method with an ultra-slim wrist cuff and a high-precision pressure sensor, paired with the TruSense system. The 26.5 mm slim mechanical air cuff enables single blood pressure measurements at the wrist. Ambulatory Blood Pressure Monitoring (ABPM) performs automatic blood pressure measurements at 15- to 30-minute intervals over 24 hours, requiring at least 70% successful readings, including 20 daytime and 7 nighttime measurements. Health & Fitness Features The Health Glance function tracks 10 key health indicators, including a score for emotional health. The pulse wave arrhythmia analysis uses the PPG sensor to detect atrial fibrillation and issues alerts. An ECG app measures the electrocardiogram in 30 seconds. SpO₂ monitoring measures and records blood oxygen saturation automatically at rest. Heart rate monitoring operates with an intelligent tracking mode that adjusts the measurement frequency based on activity level. Sleep monitoring captures average heart rate variability (HRV), sleep heart rate, respiratory rate, SpO₂, and abnormal breathing during sleep. Skin temperature monitoring estimates wrist skin temperature for healthy individuals over 18 years old. Stress level monitoring includes calming breathing exercises. For physical activity, over 80 sports modes are available, with 6 common activities detected automatically. Connectivity & Compatibility The Huawei Watch D2 is compatible with iOS and Android devices, requiring Android 8.0 or iOS 13.0 or later, along with the HUAWEI Health app. Bluetooth enables answering or rejecting calls and viewing call logs. Integrated GNSS positioning provides precise location tracking for outdoor activities. Design & Display The 1.82-inch AMOLED display reaches a peak brightness of 1500 nits, ensuring excellent readability in various lighting conditions. The strap 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. Water resistance rated IPX8 per IEC 60529:2013 means the watch withstands static water pressure up to 1.5 meters for 30 minutes. Power Supply Under typical use, battery life lasts up to 6 days. With the ABPM feature enabled, battery life is reduced to up to one day. These values represent maximum runtime under the respective usage conditions.
