The BULOVA "MEDICAL OFFICER," Circa 1942. Below are images of two dial variants, and there may well be more??? I found these images on eBay (but didn't denote the sellers) and cross- referenced the crystal proportions (scaled X x Y on my monitor) to ID this 1942 "Medical Officer," as specified in a 1942 watch crystal catalog.
I believe all of these "Doctor's watches" (regardless of watch brand?) sport the round circular seconds indexes, with numeric markings... There are also several models of Bulova nurses watches and likely several other similar (medical related) models produced, judging by some of the model names...
