HUAWEI WATCH D features a margin of error within ±3 mm Hg*, made possible by a high-precision pressure sensor, meticulous pressure feedback controls, and less air-resistance. The macromolecular tensile strap, ergonomically-arced airbag, and butterfly clasp, are all designed to remain stable during inflation, to enhance the precision of impromptu blood pressure readings.1 HUAWEI's proprietary HUAWEI TruBP blood pressure algorithm, which is based on a cascade model and different blood pressure patterns, makes HUAWEI WATCH D sensitive and considerate to the wearer's every need, with smart measurement assistance, abnormal posture detection, and a host of other high-level capabilities. HUAWEI WATCH D allows you to set customized measurement plans, based on which it will send out blood pressure reminders at scheduled times, such as wakeup and bedtime, so that you can stay on top of your blood pressure as soon as it changes. Daily check-in tasks cover a wide range of lifestyle issues, including blood pressure, exercise, and weight, making healthy living a seemingly automatic routine. The HUAWEI Health App makes it easy to share health data between members of your health community, such as blood pressure reports and abnormal readings5, so that you can always care for loved ones with the consideration that they deserve.
