I have exhausted my online efforts to identify (model name etc) this watch which was my father's. Thanks for your help!
I've always had a soft spot for this case design.
I wasn't able to find a dial match in the linebooks, but did find the silver dial version.

Generic 1967 Bulova Accutron Calendar for now until we find the variant.

Thanks for this. I couldn't find that case and face design anywhere in any color. By the way, I measured the band width at the connection point and it's 17mm, but I can find no 17mm bands. Suppose I should go with a 16mm?

Disregard the watch band question. I found some 17mm bands.
Wow I love that case design, very sharp!

Great watch, thanks for sharing it. I'm in the same place, not finding this watch with a black dial variant

1967 Bulova Accutron Calendar looks to be a general match. Still looking for a variant.
