About this reference
The Rolex Sea-Dweller reference 126603, introduced at Baselworld 2019, remains in current production as the first Sea-Dweller to feature Yellow Rolesor, a combination of Oystersteel and 18k yellow gold. Collectors evaluate this reference for its 43mm case diameter and the inclusion of the caliber 3235 movement, which offers a 70-hour power reserve and a Chronergy escapement. The dial features gold-toned "Sea-Dweller" text to match the bezel and center links, while maintaining the technical specifications of the line, including a helium escape valve and 1,220-meter water resistance. On the secondary market, this reference typically trades between $14,500 and $17,500 depending on condition and completeness. A notable production detail is the use of the Cerachrom bezel with gold-pVD coated numerals, marking a departure from the historically all-steel tool watch aesthetic of the Sea-Dweller collection since its 1967 inception.
