Sounds like the astrogation slide rule in Robert A. Heinlein's Starman Jones though as far as I recall, the actual size was never mentioned. Slide rules were also used in The Rolling Stones but I don't remember if they were circular slide rules.

Looking back, there were quite a few science fiction stories I recall where they were still using slide rules though in one, the protagonist kept referring to his pocket calculator as a slide rule.
