I had never seen this style/series Bulova before acquiring this one a while back. It's a 23 jewel Oceanographer autowind. The watch looks like it was never worn and has the biggest full-name Bulova crown I've ever seen. It's styling makes me think it is from the 70's? As an aside, I 86'ed the band in the pictures for a better looking leather one. Any additional information on it and it's value is appreciated-
Bulova coded their watches, on the back is a letter and number such as N5, the N stands for the 1970's the 5 would be the year, meaning 1975 the case was made. It should be engraved on the case back. Good luck
