5512

5512 is best known as the Rolex Submariner reference 5512, a vintage diver’s watch produced by Rolex in the late 1950s and 1960s. It is notable for being among the early Submariner models to feature crown guards and to carry chronometer certification, a combination that helped define the line’s reputation for precision and robustness. On the dial, the 5512 often bears the designation Superlative Chronometer Officially Certified, underscoring its certified accuracy.

Design and features include a stainless steel case, a unidirectional rotating bezel with a 60-minute scale, and a black dial with luminous hour markers and hands. The watch was built for water resistance suitable for professional diving, commonly cited at around 200 meters. Inside, the 5512 used a chronometer-rated automatic movement.

Production spanned the late 1950s into the mid-1960s, with various dial and bezel variants appearing over the model’s short run. Its distinctive combination of crown guards and chronometer certification, along with vintage dial configurations such as gilt or matte finishes, has helped the 5512 become highly sought after by collectors.

Legacy and market presence: the 5512 remains a focal point of vintage Rolex collecting, valued for originality—case, crown, bezel, dial, and documentation. Prices vary with condition, provenance, and the presence of original parts.
