Rolex Sea-Dweller 43mm 126603, Black Dial - 18kt Yellow Gold & Steel on Oyster Bracelet
DESCRIPTION

Rolex Sea-Dweller 43mm – Steel & Yellow Gold Two-Tone Dive Watch (Ref. 126603)

Engineered for the deep but dressed for distinction, the Rolex Sea-Dweller 126603 brings together the rugged reliability of a professional dive watch with the luxurious flair of 18k yellow gold accents. This bold 43mm timepiece is a stunning example of Rolex’s mastery in merging technical innovation with elevated design.

Crafted in Oystersteel and 18k yellow gold, the two-tone case and bracelet reflect the iconic Rolesor combination. The black Cerachrom ceramic bezel insert with gold-filled numerals surrounds a glossy black dial, featuring luminous Chromalight markers for superior underwater legibility. The date window at 3 o’clock includes the magnifying Cyclops lens — a first for the Sea-Dweller line.

At its core, the Sea-Dweller 126603 is powered by the Rolex Caliber 3235, offering a 70-hour power reserve, anti-magnetic performance, and Superlative Chronometer precision. Water-resistant to 1,220 meters (4,000 feet), this model stays true to its professional diving roots while elevating its wrist presence for everyday luxury.
