Rolex Submariner 40 mm 116613LB Steel/Yellow Gold Blue Rolex Submariner 40 mm 116613LB Steel/Yellow Gold…

The Rolex Submariner is widely regarded as the definitive dive watch and one of the most recognizable timepieces ever made. Introduced in 1953, the Submariner set the standard for professional underwater timekeeping and has since evolved into a cultural symbol worn by explorers, executives, and collectors alike. Reference 116613LB represents a particularly coveted chapter in that story, combining the rugged versatility of the Submariner platform with the elevated aesthetic of Rolex's two-tone Rolesor construction.

The case of the 116613LB measures 40mm across — the classic Submariner diameter that defined the model for decades — and is built from a seamless marriage of Oystersteel and 18k yellow gold. Oystersteel is Rolex's proprietary 904L stainless steel alloy, chosen for its exceptional resistance to corrosion and its ability to take and hold a mirror polish far longer than conventional 316L steel. The warm yellow gold crown guards, bezel ring, center bracelet links, and crown itself create a two-tone interplay that is unmistakably luxurious without sacrificing the Submariner's athletic DNA.

The blue sunray dial is immediately striking, with applied gold hour markers and Mercedes hands filled with Chromalight luminescent material for extended visibility in low-light or underwater conditions. The unidirectional rotating bezel is fitted with Rolex's proprietary Cerachrom ceramic insert in deep blue, a material that is virtually scratchproof and highly resistant to UV fading, ensuring the watch looks as vivid years from now as it does today. The Oyster bracelet, with its solid flat three-piece links, Glidelock clasp, and 5mm diver's extension, provides a secure and comfortable fit whether worn over a wetsuit or under a dress shirt.

Powering the 116613LB is Rolex's automatic movement, which offers the precision and reliability that have made Rolex a benchmark for Swiss watchmaking. The movement is housed in the iconic Oyster case, which features a screw-down Triplock winding crown and case back to deliver water resistance rated to 300 meters (1,000 feet) — far exceeding the demands of everyday wear or recreational diving. Certified as a Superlative Chronometer, the movement is tested to maintain accuracy within plus or minus two seconds per day after leaving the Rolex facility.

On the wrist, the Submariner 116613LB occupies a unique space: it is the watch equally at home at a black-tie dinner, on a yacht, or submerged in open water. The 40mm case wears with a classic, never-oversized presence that suits a wide range of wrist sizes, and the blue-and-gold color story is one of Rolex's most iconic palettes. Collectors and enthusiasts refer to this reference affectionately as the "Bluesy," a nickname that speaks to its outsized personality and loyal following.
