The Rolex Sea-Dweller 4000 (Ref. 16600) is a professional-grade dive watch designed for extreme underwater exploration. Crafted from stainless steel, its 40 mm case houses the robust Caliber 3135 automatic movement, known for its precision and durability. The black dial features luminous hour markers and hands, ensuring legibility even in the deepest conditions. This model is equipped with a unidirectional rotating bezel and a helium escape valve, vital for saturation diving.

With its no-nonsense aesthetic and tool-watch legacy, this Sea-Dweller is a coveted choice for collectors and adventurers alike.
