Huawei Watch D3 shows convenient trend tracking over 24 hours

The Quantified Scientist tested the Huawei Watch D3 with an inflatable wrist cuff for blood pressure. About 80% of readings fell within 10 mm Hg of reference monitors, but systolic pressure proved less reliable, especially with hypertension.

• 80% of D3 readings within 10 mm Hg of reference monitors
• Diastolic pressure stable but slightly above reference
• Systolic pressure less reliable at elevated pressure
• Accuracy depends on wrist position and movement
