As collectors know, the Rolex Submariner 116613LB—nicknamed "Bluesy"—is one of the most recognizable two-tone dive watches, blending classic gold and steel construction with a striking blue dial. 

The standout feature here is the 18k yellow gold and Oystersteel case paired with a ceramic Cerachrom bezel, offering durability and a timeless aesthetic. At 40mm, it wears comfortably on most wrists, maintaining the balanced proportions of the Submariner lineage. Powered by the Rolex Caliber 3135, it delivers a 48-hour power reserve with COSC-certified precision. Given its enduring popularity, this reference remains a sought-after piece in the pre-owned market. Includes a full set with box and papers.
