Rolex 126603 Sea-Dweller Oystersteel / 18K Yellow Gold Black Dial 2025

The Rolex Sea-Dweller 126603 is a masterstroke within the professional dive segment, debuting in 2019 as part of the iconic Sea-Dweller lineage. Melding the utilitarian heritage of the Sea-Dweller with luxurious touches, this model features the robust 43mm Oyster case, crafted in Oystersteel and accented with 18K yellow gold—fittingly named "Yellow Rolesor." Its intense black dial is complemented by a Cerachrom bezel insert, ensuring both resilience and a striking contrast. The heart of this reference beats with Rolex’s caliber 3235, a self-winding mechanical movement renowned for its precision, 70-hour power reserve, and Chronergy escapement. With a depth rating of 1,220 meters (4,000 feet), the 126603 continues the Sea-Dweller’s status as a formidable deep-sea instrument while introducing more versatile, two-tone appeal for both collectors and adventurers. Its Oyster bracelet, constructed from steel and yellow gold, exemplifies Rolex’s dedication to durability and elegance. As a rare blend of luxury and high-spec tool watch, the 126603 stands as one of the few true professional diver’s watches with precious metal integration, making it a notable entry in any seasoned collection.
