The Omron Platinum BP5450 keeps first at 9.3 and my ranking holds. Apple Watch Series 12 goes on sale this Friday at 399 dollars, and I expect a wave of readers asking whether it replaces a cuff. Last week I covered cuffless wearables in general. Today I want to be specific about what this watch does, because the answer makes your cuff more useful.
Series 12 has no blood pressure sensor and produces no reading in millimetres of mercury. What Apple offers is hypertension notifications. The watch looks for patterns over roughly a month that suggest chronic high blood pressure, then tells you to go and get checked. That is a screening prompt, and the step it prompts is a week of proper cuff readings.
So here is the protocol I give anyone who gets that alert. For seven days, sit quietly for five minutes, then take two readings a minute apart in the morning before coffee and two in the evening before dinner. Use an upper arm cuff sized to your arm, arm resting at heart level, feet flat. Take the averages to your doctor. That is the evidence a clinician can act on.
This is where my top three earn their places. The BP5450 automates the two-reading routine with TruRead averaging and stores every session. The Withings BPM Connect at 9.0 syncs straight into Apple Health, so your cuff readings sit beside the watch data that triggered the alert. The Omron Silver BP5250 at 8.8 gives you the same Omron validation at a lower price for a household that just wants the numbers.
If the alert arrives before October, Prime Big Deal Days runs 6 and 7 October. I would still buy the cuff the week the alert appears, since seven days of readings matter more than a discount.
