The Rolex Sea-Dweller 126603 “Two-Tone” marries deep-sea capability with refined elegance. Its 43 mm Oyster case combines corrosion-resistant 904L steel with 18k yellow gold accents—most notably the unidirectional bezel and winding crown. The black dial features bold luminescent hour markers and hands engineered for underwater legibility, while the date window at 3 o’clock retains the Sea-Dweller’s tool-watch heritage. Rated to 1,220 m water resistance, the 126603 retains serious diving capability yet delivers a more elegant demeanor thanks to its gold elements.

The Rolex Sea-Dweller 126603 brings the iconic deep-sea tool-watch into a luxurious new dimension. At 43 mm, its Oyster case is forged from corrosion-resistant Oystersteel and accented with 18K yellow gold, combining strength and elegance in the classic Rolesor dual-metal scheme. The unidirectional rotatable bezel features a black Cerachrom ceramic insert with gold-filled graduations, offering scratch-resistance and sharp contrast, while the Oyster bracelet links merge steel and gold in a balanced, bold profile.

The black dial maintains Sea-Dweller’s signature high-visibility design, with oversized Chromalight hour markers and hands that glow blue in low-light conditions. The “Sea-Dweller” label is rendered in gold to echo the two-tone detailing. A date window at 3 o'clock—magnified by the Cyclops lens—preserves the familiar Rolex layout while aligning with the watch’s professional diving lineage. The helium-escape valve on the case side remains an integral feature for saturation diving integrity.

Under the hood, the in-house automatic Caliber 3235 provides approximately 70 hours of power reserve, enhanced precision via Rolex’s Chronergy escapement, and robustness against shocks and magnetic interference. Water resistant to 1,220 meters (4,000 ft), the 126603 balances serious dive functionality with regal aesthetics, making it a compelling choice for collectors who demand both performance and presence.
