Huawei Watch D is a compact smartwatch with plenty of features. The watch has, among other things, a micro air pump and an air bag enabling more accurate blood pressure measurement. The new TruSee 5.0+ tracking technology ensures that you can also measure your heart rate even more accurately. In addition, the watch's wide range of health functions includes, for example, SpO2 measurement, sleep and stress monitoring, as well as more than 70 exercise modes, such as running, cycling and jumping rope. The watch has a battery life of up to 7 days, so it won't leave you stranded in the middle of a training week. The Huawei Watch D condenses a complex blood pressure measurement system into a very compact size. The curved 2.5D glass glistens elegantly on the wrist and is a great companion to the durable aluminum alloy frame. Two convenient buttons help you quickly get to your tasks. The error margin of the Huawei Watch D blood pressure measurement is ±3 mmHg, which is made possible by a very accurate pressure sensor, careful pressure management and reduced air resistance. The special strain-resistant cuff, ergonomically curved air bag and butterfly flap are all designed to remain stable during air bag inflation, improving the accuracy of spontaneous blood pressure readings. The original Huawei TruBP blood pressure measurement algorithm, based on the waterfall model and various blood pressure formulas, makes the Watch D smart watch adaptable to the user's needs. The high-level features of the device include, for example, an intelligent measurement assistant and recognition of an unusual position.
