About this watch

The Rolex Sea-Dweller 126603-0001 is a masterpiece that effortlessly combines luxury, functionality, and performance. Its striking design features a blend of stainless steel and 18-carat yellow gold, creating an eye-catching contrast that is both bold and elegant. The black dial serves as a perfect backdrop for the luminous hands and hour markers to pop. With a diameter of 43mm, the case is substantial yet comfortable on the wrist. The rotating bezel allows divers to measure their dive time accurately, while the sapphire crystal offers excellent visibility and scratch-resistance. Water-resistant up to an astounding 1220 meters (4000 feet), this watch is perfect for serious divers. At the heart of the Sea-Dweller lies the Rolex caliber 3235, a movement that speaks volumes about Rolex’s commitment to precision and performance. Certified as a Swiss chronometer by the COSC, the Sea-Dweller is tested rigorously for precision. With its advanced movement, date display, Mercedes hands, and Oyster case design, this watch is a reliable companion for divers and adventurers alike.
