Rear of case is marked Bulova, Gold Electroplate Bezel, Stainless Steel Back, N2 date code. Engraved "Love Forever 5-7-75". Movement is marked Bulova Watch Co., 17 Seventeen Jewels, 11ANC, Swiss, Unadjusted, N1 date code is stamped on movement. Why is the case date code different than the movement date code? Speidel band with two links added. My Father-in-Law was a big man.
That's a beauty, and is a Sea King "GK", as in this 1972 ad.
The description and picture matches your watch perfectly.

Hi rogersonw, welcome to myBulova. Nice looking watch. Remembering that the difference between 1971 and 1972 is but one day, it appears that your movement was made in late 1971 and by the time it got to the assembly line the 1972 cases were being used. Not at all an uncommon occurrence.
I agree with Bob - it's a Sea King GK
