In 1964, Bulova had 39 calendar models available. My best guess for this watch is a Sea King, or Date King. This is a manual-wind with a hacking second hand. The watch is well-built. The dial face is common for Date King, Aerojet, and Sea King for this era. The ads for a manual wind, calendar dial watch for 1964 are uncommon. The Date Kings all seem to have self-wind movements and non showing " Waterproof" on the dial. The Aerojets, all have "Aerojet" on the dial. I need your help with the 1964 Line Book to help narrow it down. Thanks
Assuming it is white gold filler..then it looks like a Bulova President "B" from 1964_LineBook_BAWD0156 page 29.
Stainless steel case is a match.

Linebook shows the models with the dial crosshair as being part of the Date King series.

Thank you! I can see it now. Bottom left watch in the ad. 1964 President "B"
I am going to agree, per line book and also period ads
1964 President "B"
looks to be a match.
good call for 1964...President 'B'
1964 President "B" is a match!
