Unveiled at Baselworld in 2019, the Rolex Sea-Dweller reference 126603 is a hybrid of a robust diver’s wristwatch with a touch of gold. Combined for the first time Rolex’s 904L Oystersteel and 18K yellow gold, the two-tone construction Sea-Dweller not only distinct itself with its good looks, its remarkable depth rating of 1,220 meters / 4,000 ft inscribed at 6 o’clock on the black dial echoes the colour of yellow gold with luxurious appeal. Similar to its sibling ref. 126600 with all-steel counterparts, the Sea-Dwellers are equipped with the caliber 3235 movement for superlative performance. A consummate demonstration of Rolex technology with 14 patents, it offers fundamental gains from precision, power reserve, high energy efficiency and great reliability thanks to the Chronergy escapement. Made of nickel-phosphorus, it is also insensitive to magnetic interference. An elevated choice for collectors seeking for not the average diver’s Sea-Dweller, the present ref. 126603 preserved in excellent overall condition accompanied with its full set of accessories is certainly one to go for.
