I would say that it will "Flight Nurse" from the sixties like this http://www.mybulova.com/watches/1961-flight-nurse-6637
although pictures are blurry, but I see on the movement "Mx" indicating the date of manufacture
I'd say this is another good match to the Flight Nurse, just like the linked version, Yellow Gold, same dial, red second hand, same movement, same case, taller crystal. We need to confirm the date, M?; by 1964 there were 5 variants listed. The 61 I listed is the yellow 'B', only other option at that time was the white 'A'. In 64 there were three more in addition to the 'A & B'; E was round, 'I' was very similar to the A & B with different band, 'J' unknown but probably the white or yellow version of 'I'. I don't have a number stamped on the inside caseback of mine to compare.
Flight Nurse, possibly 'B', year unknown
We would need a photo of the caseback showing the datestamp of M#
