Stunning pictures. Sure looks like the Flight Nurse to me. ...even w/ original bracelet!!
I see in the 1954 November price list, we have American Nurse and Air Nurse....and as noted, Flight Nurse came along a little later.
At the very first few pages of the price lists Ken used, there is a section which indicated new watches (by men and women). This preceeds the entire price list. This earlier new watches section often gives the gold color of variants, and sometimes dial color. Below is a snippet from this part of the Fall 1961 price list giving gold color by variant for both listed Flight Nurse watches.
Ken I say you have a "Flight Nurse" variant "B" (the W or Y in second column corrisponds to gold color. There is no "key" to state this fact, but it's been demonstrated true in countless other watches for which we have ads listing variants and showing gold color).
