Blood Pressure Watches

[Tarser]

I would like to buy a simple blood pressure watch (not a cumbersome wrist monitor) - just one that looks like a watch / fitbit type of thing. It seems that I have to have a smart phone/bluetooth/android and all the other slightly incomprehensible things someone of my age doesn't really get! I want to look at my device at various times of the day and for it to tell me what my BP is - nothing more. Does such a thing exist?
