Bulova and many others did and still do use base 7750's they are mostly base grade movements that are no where near top or COSC grade although Bulova did order them with incabloc for some pieces.
Breitling, Tudor (owned by Rolex), Omega, etc, modify the COSC grade even further to improve quality and performance.
I like ebel for their Cal 137 which is an a COSC grade in house movement that is so good Breguet uses it in their type XX and more recently is being used by Ulysse Nardin.
The 7750 was born in 1975 IIRC to be a work horse not a high end movement, it takes a lot of work to get it past that.
You might find this interesting.

Yep, I remember that WUS thread well. A regulated 7750, even in low-end form, is often just as good as the COSC ones but without the ridiculous markup. Heck, I have a Chinese Unitas that I've regulated to within a few seconds a day.
