Available today is a Rolex Sea-Dweller reference 126603, a bold and robust take on the classic diver’s tool watch combining the technical prowess of the Sea-Dweller with the refined luxury of Rolex’s two-tone Rolesor construction.

This modern Sea-Dweller is housed in a 43mm Oystersteel and 18k yellow gold case, with a unidirectional rotatable Cerachrom bezel featuring gold-filled numerals and graduations. The dial is deep black with luminous hour markers, a date window at 3 o’clock, and the signature “Sea-Dweller” in gold text — exclusive to this model variant. The watch is fitted on a matching two-tone Oyster bracelet with Oysterlock clasp and Glidelock extension.

Powering the 126603 is the Rolex Caliber 3235, a COSC-certified automatic movement with 70-hour power reserve, Chronergy escapement, and Parachrom hairspring, offering premium performance and durability.

This example is in excellent condition, showing light wear on the case and clasp. It comes complete as a full set with the original inner and outer boxes, green warranty card holder, and Rolex international warranty card.
