Rolex Sea Dweller 116660, Stainless Steel, "Deep Blue", Oyster Bracelet, 44 mm

The Rolex Sea-Dweller 16660, often referred to as the Triple Six, represents an important transitional reference in the history of Rolexs professional dive watches. Crafted in stainless steel, the robust 44mm Oyster case is equipped with a unidirectional rotating bezel, helium escape valve, and sapphire crystal, making it one of the first Sea-Dweller models capable of withstanding depths of up to 1,220 meters (4,000 feet). The deep black dial, nicknamed Deep Sea or Deep Blue by collectors for its subtle tonal variations over time, features luminous hour markers and Mercedes-style hands for maximum underwater visibility. Inside beats the Caliber 3035 automatic movement, offering reliability and a quickset date function. Paired with the solid-link Oyster bracelet, the 16660 is a historically significant model that bridges vintage design with modern Rolex technology, making it highly collectible among enthusiasts.
