When Rolex launched the 43mm two-tone Sea-Dweller in March 2019, the watch world was stunned. Looking magnificent in 18ct yellow gold & steel, the 126603 really is one of the most radical Sea-Dwellers ever made. This 2020 example is under Rolex international warranty to July 2025. Waterproof to 4000ft and powered by the latest updated calibre 3235 automatic date movement with Chronergy escapement and improved power-reserve. Complete with Rolex box, Rolex warranty card, chronometer swing tag and instruction booklets.
