Rolex 126603, Stainless Steel and 18K Yellow Gold, Black Dial, Oyster Bracelet, 43 mm

The Rolex Sea-Dweller 126603 is a bold two-tone execution of Rolexs professional deep-sea diver, blending robust engineering with precious metal refinement. Its 43mm Oyster case is crafted from a combination of stainless steel and 18K yellow gold, topped with a unidirectional rotating bezel fitted with a black Cerachrom ceramic insert. The black dial features Chromalight luminous hour markers and Mercedes-style hands, providing outstanding visibility in the darkest conditions. A date window at 3 oclock, magnified by the Cyclops lens, enhances practicality, while the Oyster bracelet in steel and gold offers both strength and elegance. Engineered for extreme conditions, the Sea-Dweller 126603 is water-resistant to 1,220 meters (4,000 feet) and equipped with the helium escape valve for professional saturation diving. At its heart, the Caliber 3235 automatic movement delivers a 70-hour power reserve, Rolexs Chronergy escapement, and Superlative Chronometer precision. With its dual-metal construction and formidable performance, the 126603 is a professional-grade tool watch with luxurious appeal.
