Few watches have played a more important role in shaping the modern sports watch than the Rolex Submariner. Introduced in 1953 and commercially launched the following year, it established a design that would become the benchmark for professional diving watches. Among the most significant references in its evolution is the ref. 5512, introduced in 1959 and produced for nearly two decades. It brought crown guards to the Submariner for the first time, creating the familiar silhouette that remains central to the collection today. Alongside its sister reference, the 5513, the 5512 helped establish the enduring formula of the modern Submariner, combining professional diving functionality with Rolex's increasingly sophisticated approach to precision and durability.

Dating to 1969, this example belongs to the desirable generation of four-line, chronometer-certified Submariners with a 'Meters First' dial, displaying the depth rating as 200m = 660ft rather than the later feet-first arrangement. This transitional period is particularly interesting to collectors, marking the gradual evolution of the Submariner's dial design during the late 1960s. Powered by the automatic calibre 1570, the watch retains the traditional 40mm Oyster case, black rotating diving bezel and domed acrylic crystal that define the vintage Submariner aesthetic.
