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

The Rolex 126603 Sea-Dweller stands as a significant evolution within the professional dive watch category, bridging both robust design and precious detailing. Released in 2019, this reference heralds the integration of Oystersteel and 18K yellow gold, a two-tone execution known as 'Yellow Rolesor,' which imparts a notable luxury presence while retaining Sea-Dweller’s uncompromising tool-watch spirit. The 43mm case, with its iconic Oyster construction, offers serious functionality for technical diving, underscored by a helium escape valve and a depth rating of 1,220 meters. The black Cerachrom bezel and intense black dial provide exceptional legibility under all lighting conditions, making use of Chromalight lume for low-light environments. Powered by Rolex’s in-house Caliber 3235, it delivers a robust 70-hour power reserve and the brand’s latest Chronergy escapement for improved efficiency and reliability. The triplock crown and solid-link Oyster bracelet ensure both security and enduring comfort on the wrist. As a modern Sea-Dweller, the 126603 remains highly coveted among enthusiasts seeking an all-purpose diver that unites technical prowess with unmistakable two-tone elegance. Quite rare among previous Sea-Dwellers, the gold accents give this reference a special status for collectors who value both performance and sophistication. Its presence marks a compelling intersection between Rolex’s professional heritage and evolving luxury sensibilities. Like New with Rolex box and papers dated 2022.
