ROLEX Sea-Dweller Deepsea 116660 Black Men's Used — USD 10,746

The Deepsea reference 116660 represents a significant evolution in Rolex's professional dive watch offerings, positioned above the Submariner and Sea-Dweller in terms of water resistance and case dimensions. Introduced in 2008, this model was engineered for extreme underwater exploration, featuring a robust case construction designed to withstand immense pressure. It established the Deepsea as a distinct and highly capable instrument within the brand's catalog, catering to serious divers and enthusiasts of substantial timepieces. This reference features a 44 mm Oyster case crafted from 904L stainless steel, with a notable thickness of 17.7 mm. It is equipped with Rolex's patented Ringlock System, which incorporates a nitrogen-alloyed stainless steel compression ring, a 5.5 mm thick domed sapphire crystal, and a titanium case back. Powering the watch is the automatic Caliber 3135, a COSC-certified chronometer movement known for its reliability and precision, offering a power reserve of approximately 48 hours. The 116660 appeals to collectors who value technical prowess and a commanding wrist presence. Its substantial proportions and advanced engineering distinguish it from other dive watches, making it a statement piece. The model was produced with a black dial and a unidirectional rotating ceramic bezel. This reference laid the groundwork for subsequent Deepsea iterations, including the D-Blue dial variant, and remains a key reference for understanding the development of Rolex's ultra-deep diving watches.
