The Rolex Submariner 5513 is one of the core references in the vintage sports lineup, and this circa 1978 example shows the no-date model in its late-1970s form. It has a 40mm stainless steel case and bracelet with a black serif matte dial, a combination that gives the watch its plainspoken tool-watch look. The automatic movement keeps the format simple and practical. On the wrist, the proportions are balanced and familiar, which is a big part of why the 5513 still holds attention.
