The Rolex Submariner Reference 5512, introduced in 1959, is a pivotal model in the history of dive watches, setting the standard for the modern Submariner design. It was the first reference to feature crown guards, an essential evolution in case construction that protected the screw-down crown and improved durability underwater. The watch maintained the classic 40mm stainless steel case, a rotating b🏅ezel for tracking dive times, and a highly legible dial with luminous hour markers and hands. Unlike its sibling, the Reference 5513, the 5512 was chronometer-certified, making it the more premium and technically refined option. Over its two-decade production run, the model saw various dial configurations, transitioning from gilt glossy dials with radium lume in the early 1960s to matte dials with tritium lume in the later years. The watch housed multiple movements, including the Caliber 1530, 1560, and 1570, ensuring precise timekeeping.

The 5512 is highly sought after by collectors, not just for its historical significance but also for its associat🃏ion with pop culture icons such as Steve McQueen, who famously wore the model. Early examples with pointed crown guards (often referred to as “Eagle Beak” or “PCG”) are particularly rare and command high prices in the vintage market. Additionally, variations like the four-line dial (which includes the "Superlative Chronometer Officially Certified" text) ღand certain gilt-dial versions add to the desirability of this reference. With its rugged elegance, timeless design, and historical importance, the Rolex 5512 remains one of the most collectible Submariners ever produced, embodying the brand’s commitment to precision and durability.
