The Rolex Sky-Dweller Yellow Gold Oysterflex Black Dial 42mm ref. 336238-0002 offers advanced functionality in a bold design. Its 42mm case in 18k yellow gold features a signature fluted bezel, both a hallmark of Rolex craftsmanship and a functional component of the Ring Command system, which allows seamless adjustment of the watch’s settings. The bright black dial includes an off-center 24-hour disc for a second time zone, highlighted by a red triangle, while the Saros annual calendar automatically displays the correct date and month, requiring adjustment only once a year. The Oysterflex bracelet, with a titanium-nickel alloy blade overmolded with durable black elastomer, combines robustness with comfort. The bracelet features a patented cushion system for stability and a yellow gold Oysterclasp with the Glidelock extension system for fine adjustments of up to 15mm. Powered by the Calibre 9002 movement, this COSC-certified chronometer delivers a 72-hour power reserve. Water-resistant to 100m, this 2023 release is built for versatility.
