This is an incredibly rare and desired watch in amazing condition with all original box and accessory! It is a casio "Blood pressure Monitor" watch, where there are some different models that are all rare. This is the BP-1B watch, which was sold with additional blood pressure monitor sensors. Usually, there are not these sensors available, so the watch cannot read blood pressure. But for this one, they are here!! All of the machines have not been touched! The arm strap is like new! It is really amazing to find this whole collection in this amazing condition. Even the original batteries in the packaging!
The design of the machine is extremely Japanese style, it is even possible to tell from the colour.
The watch has been checked for function and is working properly and keeps good time. All special data recording functionality has been tested and is working properly. There are no dead pixels on the screen. I have not tested the pulse machine. The watch battery has been replaced and fresh sealant grease has been applied to the rubber gasket. The case and the strap have been cleaned thoroughly.
Measurements of case size and wrist size can be found in images.
