This Rolex Submariner Ref. 5513, dating back to the early 1970s, is a remarkable example of the iconic dive watch. It features the sought-after Serif Dial, characterized by distinctive serif-like details on the hour markers, adding to its vintage appeal. The matte black dial has developed a stunning, even patina, enhancing its unique character. The watch is complemented by a highly desirable MK3 "Fat Font" bezel insert, known for its bold numerals and period-correct design. Housed in a 40mm stainless steel case, it retains the robust and timeless aesthetics of the Submariner line. Powering this timepiece is the Rolex Caliber 1520 automatic movement, ensuring reliable performance. Completing the look is a later solid Oyster bracelet, offering a perfect balance of vintage authenticity and everyday wearability. A true collector’s piece, this 5513 embodies the enduring legacy of Rolex tool watches.
