Hi,
I was reading through the register and had some questions about the Heuer pulsations chronograph. I wondered if anyone could help?
The 1950s Heuer pulsations that were listed all seemed to have "Calcule sur 15 pulsations" on the dial. I happened to come across an image of a Heuer with "base 30 pulsations" on the dial. I wondered if this might be fake or if Heuer did produce Pulsations in 15, 30 and 50 variants?
I understand that pulsations were used by doctors to monitor/measure heart rate but why were different variants of pulsations produced and how did they differ in there use?
