This is what I think I know: Back of case base bears N7 stamp (so 1977). Swiss quartz movement, tritium lume, gold tone case, brown face with vertical stripes (dark on edges and fades lighter toward center), numerals to mark hours (except for 3 where there is a dual-day complication), Accuset button, aftermarket gold tone expansion band.
Refurb: My watch guy was reluctant to attempt removing the crystal for polishing, due to its rarity and the likelihood it might be broken in the attempt. He handed it over to a fellow professional who polishes gem stones, and that guy did his best to clean up the crystal without polishing the gold finish off the case. The watch came to me with a Speidel band, perhaps because it was owned by my father-in-law, who was a very big man. I'd guess it originally had a gold tone bracelet of some kind, but the one example I did see online had no band, so I cannot confirm that.
I'd like to know: I'd guess the model would simply be referred to as Bulova Accutron Quartz, or perhaps Bulova Accutron Quartz Dual-Day? It may have 242 movement, which may be inscribed inside case back, but I can confirm neither. I'd be interested to learn the proper term for the interesting brown face treatment. I'd like to know what the original band/bracelet was like. I'd like to know the proper terms for the case and crystal shapes. I'd love to know any other facts about the model that might be available. I have only seen one watch like it online, so I wonder how rare this model might be? I'd love to see an image of a sales brochure showing this model.
Thanks for you help!
Have spent a bit of time search for an advert or linebook entry for this exact model.
So far I've only found this 1977 advert showing your watch and the original bracelet.

I see it! Just to the right of center. Very cool. Thank you so much!
I did a bit more research and found that many Bulovas of this era originally came with Speidel bands. It got me wondering if the Speidel band I found on the watch was actually original, rather than my father-in-law's modification as I had assumed. The band in this advert does look something like that original band, which is shown in my first photo.
Wow - a real survivor! 1977 Bulova Accutron Quartz Date and Day makes sense to me.
1977 Bulova Accutron Quartz Date and Day is a good match until a model number is found.

Would the model number be indicated somewhere on the watch? If so, where am I likely to see it? I will look for it and get back if I find something.

No, it would not. In this era, Bulova stamped a case reference number inside the case back that can be used to look up replacement part numbers for the various component. but alas, we are left to pore over old catalogs and advert to determine (when possible) model names or numbers.
