In production for more than 25 years from 1962 until 1988, the Rolex Submariner ref. 5513 was the first Submariner models to feature crown guards for enhanced robustness along with its sibling ref. 5512. Initially produced with glossy lacquered dials for a short production span of approximately four years, Rolex started to introduce the matte dials like the present example since its inception from 1966. The present Submariner 5513 is no ordinary matte dial, featuring the meter first depth rating indicative for only early production specimens, making this a highly collectible example for many. Other distinctive elements that give hints of an early matte dial is the semi-open 6’s depth rating, Swiss-T<25 spanning across a total of five minute has marks at the bottom edge of the dial. Bearing a 1.617 serial and the inside caseback stamped second quarter of 1967, the present example boasting a strong case with defined bevels is certainly period matching. Furthermore, the patina on the indexes have ages into a beautiful warm buttery hue, making this an incredible vintage find from the early matte dial series.
