I've been on a '70's Bulova kick lately and this one fits perfectly in that funky groove. This looks to be the "11636-8W" model, marked N3 on the case back and movement. The inside case back has two numbers, 7366 and 109E, neither of which are in the ABC parts catalog. This one came with an Accutron band. Does this style of band (where it takes a push pin instead of a spring bar) have a name?
I really like this one. Your naming is correct. It first appears in the 1974 Linebook, but has no name.

1973 Bulova Model 11636-8W looks to be a match. love the big 70's watches.
If I wanted to replace the band what kind of band should I look for? This one doesn't take a spring bar and the band straddles the lug vs. being on the inside of the lug.
Some of these do indeed use a smaller spring bar, they're a bit fussy to get in and out. This may or may not be one of those. That arrow might be indicating the direction to remove a friction or split pin also. If that is the case, you just use a small pin punch/remover.

Yes, this one is friction fitted. I was just wondering that if I were to replace the band what type or model of band is this called (with one central lug instead of two lugs) as I wouldn't know what to search for.
Classic 70s!
