Doctors Dial.

  Is anyone aware of a VC model produced in the late 1940s to early 60s with the so called "Doctors Dial".This consists of a base with the pulse and respiration rate markings.
Thank you.

You must be referring to chronograph models. As far as I know

2 models were produced with the "double" indication you mention: pulse and respiration. Which by the way are extremely rare as most so called doctor's dial chronos had only the pulse rate (but in any event these models are also extremely rare)

Ref 4178 whith the iconic tear drop lugs

Ref 4072 with straight lugs
