It's a pulse scale

 

It’s a pulse scale as in any other doctor’s watches (some nice vintage ones are from Girard-Perregaux); works as follows (from the web):

 

“The pulsometer is perhaps the most useful bezel scale for modern everyday use. Find a pulse, start the chronograph and stop it after counting the number of heartbeats designated on the scale. The resulting bezel reading will be the person’s heart rate. Watches with pulsometric scale are sometimes called doctors’ chronographs, for obvious reasons.”
