Objective The aim of this study was to evaluate the accuracy of the watch-type automated oscillometric wrist blood pressure (BP) monitor HUAWEI WATCH D in the general population according to the Association for the Advancement of Medical Instrumentation/European Society of Hypertension/International Organization for Standardization (AAMI/ESH/ISO) Universal Standard. Method Subjects were recruited to fulfill the age, sex, BP and cuff distributions of the AAMI/ESH/ISO Universal Standard in the general population using the same arm sequential BP measurement method. Two cuffs of the test device were used for wrist circumference of 13–16 cm (medium) and 16–20 cm (large), respectively. Results One-hundred and nine subjects were recruited and 85 were analyzed. For validation criterion 1, the mean ± SD of the differences between the test device and reference BP readings was −1.4 ± 6.47/−0.2 ± 5.85 mmHg (systolic/diastolic). For criterion 2, the SD of the average BP differences between the test device and reference BP per subject was 5.66/5.48 mmHg (systolic/diastolic). Conclusion The HUAWEI WATCH D watch-type wrist BP monitor fulfilled all the requirements of the AAMI/ESH/ISO Universal Standard in the general population and can be recommended for self-measurement.
