A prime example of Rolex’s iconic dive watch, the early-1970s Submariner Ref. 5513 features a 40 mm stainless steel Oyster case with a bi-directional rotating timing bezel and a gently domed acrylic crystal. Its rare matte-black serif dial—noted for the small “feet” on the depth-rating text—boasts creamy, patinated luminous hour markers paired with classic Mercedes-style hands that echo the dial’s warm hue. Powered by the robust Caliber 1520 automatic movement, it delivers reliable performance both above and below the waves. Fitted on its original folded-link Oyster bracelet, this piece retains full vintage character and wrist presence. Complete with original box and papers, it stands as a highly collectible testament to Rolex’s mid-century dive-watch heritage.
