HUAWEI WATCH D2 fascinates with its 1.8-inch AMOLED screen and 1500-nit peak brightness, but it’s even more than meets the eye, telling you about your health in an instant. The watch measures vital features with greater speed and accuracy, thanks to a multi-region optical path design, advanced optical architecture, ultra-precision glass darkening technology, and next-generation health monitoring algorithms. The brand-new HUAWEI TruSense system of the watch is enhanced by a high-precision pressure sensor, a mini pump and an inflatable airbag for accurate BP measurements. It is now able to monitor six key systems, including the respiratory, nervous and endocrine systems, to make digital health more accessible and complete for everyone. New and improved electrode technology has made ECG signal collection more accurate and responsive. Touch the side electrode for 30 seconds to get real-time data that can help you screen for common heart disease at the earliest occasion. * The European Society of Hypertension (ESH) practice guidelines for outpatient blood pressure monitoring recommend 24-hour BP measurements at intervals of 15-30 minutes, with at least 70% successful measurements, including 20 daytime and 7 nighttime measurements. Data obtained while using this product is for reference only and should not be used as a basis for medical examination, diagnosis or treatment. This feature will be made available through OTA updates to the latest version.
