The Rolex Submariner 5512 “Chapter Ring” is a rare and iconic vintage dive watch produced in the early 1960s. Distinguished by its unique chapter ring—a printed circle on the dial connecting the hour markers—this feature is a hallmark of early Submariner models. The 5512 also features a stainless steel case, rotating bezel, and Mercedes hands. It was one of the first Submariners to include crown guards, giving it a more robust design. Coveted by collectors, the “Chapter Ring” version of the 5512 is celebrated for its historical significance and classic aesthetics.
