Smart watches don't do blood pressure monitoring currently as far as I aware. There is a bunch of Chinese crap that will happily make up a number for you, but it's all crap. I suspect, it's just not something you can do based on optical sensors.

I looked around, but the only product that seems to be working, and you can actually buy is this: https://aktiia.com/uk/blood-pressure-monitor

Interesting, thanks for the link. Not available in the US yet, but I'll be keeping an eye out for this.

... have optical heart rate and pulse oximeter sensors which are totally different from blood pressure

he said smart watces dont do blood pressure monitoring. They do. I dont know anything about method used and accuracy.

Apparently it does have a blood pressure measurment, "based on pulse wave velocity (PWV) method to estimate systolic and diastolic blood pressure".

>For accurate blood pressure readings, Samsung recommends that a calibration is required every four weeks with an arm cuff and blood pressure monitor, so be prepared to buy one of these to get the most out of tracking blood pressure on the Galaxy Watch. Users should also measure their blood pressure while at rest and not during a workout.

People have different experiences about the accuracy: https://eu.community.samsung.com/t5/wearables/blood-pressure-reliability-amp-accuracy/td-p/2925769

Anyway, OP might find this an interesting lead to follow.
