(Sorry for the poor image quality as my room lighting is not good today). I bought this BP-100 BP monitor watch in early 1980's and gifted it to my dad. He was suffering from irregular blood pressure levels then, and needed to visit the doctor frequently. After few trials and errors, he was able to monitor his BP with this watch on a regular basis, keep track of it and report it to the doc every fortnight. Even the doctor was surprised and happy to see the functions of this watch and he recommended this gadget to many of his inquisitive patients.

I have kept the watch in my collection after the death of my father in 1995 as a memento. I change its battery every few years, and as you can see in the image, the watch is still fully functional. I off course do not wear it, despite myself being a BP patient now , as many more advanced devices for BP measurement are available to us now.

Some real tough products were made that time!
