Yellow 10k rgp bezel case with stainless back plate. Case has the M9 code and is about 32.4mm across without the lugs and crown. White dial background with raised yellow linear indices. Yellow, sharp pointed hour and minute hands with a sub-seconds hand. Nice watch with classic, clean lines. Saw a 1966 Centennial on the site that looks similar, but was unsure if this was a match. - Thanks for any input!
Another option for 1969 would be the Centennial "B". Both likely used the same case.
The original band may have been swapped for leather, and the dial in the linebook for the Craftsman shows different markers.

The difference between the two appears to be the dial. The Centennial says Silver dial and the subject watch has a white dial. 1969 Bulova Craftsman "AB" seems to be the correct match based on the referenced watch I own that was previously id'd based on the reference ad in the listing.
I'm with Ken based on the dials, one has numerals, one has hash marks. 1969 Bulova Centennial B
Agreed, Centennial B looks like a better march,
