Here's my 1967 cal 321 Speedy with a Pulsations or Doctor's bezel. It is used to measure heart-rate by recording the time it takes for 15 heart-beats. The watch is stopped after the 15th beat and the equivalent BPM is displayed.

What do you reckon to this one?

Does under 40 mean the patient is dead? No readings lower!
