Elderly relatives often buy smart watches or fitness bracelets to monitor the physical condition of the body. Such devices display heart rate, blood pressure, blood oxygen saturation level and other health indicators on the screen. Their accuracy is sufficient for a person whose data is normal, plus or minus. But you should understand that smart watches do not measure pressure, but calculate its approximate value using indirect parameters:
frequency and amplitude of the pulse; uniformity of the pulse rhythm; light permeability of the blood, etc.

Doctors recommend models where the cuff is worn above the elbow, since they have minimal error. But a compact device on your wrist can be carried with you and is easier to use on your own.
