Self winding, cream dial with applied markers and Arabic numerals, date window, stainless round case
Thank you for posting your watch. Based on the 1964 Linebook this is a 1963 Date King. Variant N has a leather strap and Variant U and X has a stretch bracelet. As you presented your watch with a replacement bracelet, I would classify this as a 1963 Bulova Date King "N"

Jim, I've found that 1963_LineBook_BAWD0151.pdf (page 46) also lists the middle watch as a Jet Clipper "I".
Advert also.

Generic 'DATE KING' would be a more suitable ID as the band does not match the 'N', the 'U' nor the 'X'.
pushing too hard to identify these model variants and getting them wrong, imo.
I'm noting a diffrence in all 3 hands. Generic Date King would be my preference, noting how the watch is being presented.

Good eye on the Hands, they definitely do not match (the ads.)
Seems 1963/64 might just be the cutover from Jet Clipper to Date King.
I did find the watch in the 1963 linebook as a Jet Clipper. 1963 Jet Clipper

I think it wants to be a 'JET CLIPPER'
*Note the Hands.
ad is 1962
I would go with Jet Clipper as it is in the 1963 linebook. As Stephen said this is probably the changeover year to Date King. Both types of hands were used on the Jet Clipper.
1963 Bulova Jet Clipper
Agreed - model transition. Based solely on date , dial shown in B/W ad and hands as seen in color ad -
1963 Jet Clipper (no variant yet)
