Blood pressure estimation from heart rate sensor

I wondered how the original firmware was supposed to get blood pressure from the available sensors. Perhaps it was using one of the methods outlined in the link. Samsung's latest watch is claiming to measure blood pressure too, but needs calibration from a normal cuff at least every 4 weeks to maintain accuracy.
