Referencing 1972 Vintage Bulova Ad - Courtesy of Fifth Avenue Restorations
Debut P - matches the case seen/described, and the description overall seems to match the best
Debut H - matches the description of the face a bit better because it specifically mentions the blue and red lines (although it's more burgundy/teal)
Debut E/F - matches the band
All of these say 17 jewels, and since I do not know how to open to case (yet), I am going off the front which indicates 23.
Also looks a bit like a Concerto or Laurel in various other ads I looked through in the forums. I have no real investment (other than more time than I'd like to admit) in whether this watch is any of the above models, or something I did not find. I did have fun though! Please excuse any amateur mistakes in my findings. Happy to learn, and open to critique :) **The 5th image is suppose to be a close up of the watch band, which is 5mm wide and stretches. On the back says "Speidel U.S.A. Pat 3.307.349"
