The Rolex Sky-Dweller reference 336239-0002 is a 42mm luxury travel watch featuring a case crafted from 18kt white gold. This model is characterized by its bright black dial with white gold index hour markers and a bidirectional rotatable fluted bezel, which functions as the Ring Command system for adjusting the watch’s various settings. It is equipped with an Oysterflex bracelet, which integrates flexible titanium and nickel alloy blades overmoulded with high-performance black elastomer, and is secured by a folding Oysterclasp with the Rolex Glidelock extension system. The watch is powered by the manufacture caliber 9002 self-winding movement, providing a 72-hour power reserve and water resistance up to 100 meters.
As Rolex’s most complicated timepiece, the Sky-Dweller includes a dual time zone display and the Saros annual calendar. Local time is indicated by the conventional center hands, while a second time zone is tracked via an off-center 24-hour disc. The annual calendar automatically distinguishes between 30 and 31-day months, requiring only one adjustment per year on March 1st. The current month is indicated by 12 discreet apertures around the circumference of the dial, with the active month marked in deep red. This sophisticated movement also features the Chronergy escapement and high-performance Paraflex shock absorbers for enhanced reliability and efficiency.
General reviews of the Sky-Dweller reference 336239-0002 often emphasize its technical sophistication and the intuitive nature of the Ring Command bezel. Collectors appreciate the “understated luxury” of white gold paired with the sporty aesthetic of the Oysterflex bracelet, noting that it offers a more contemporary and comfortable alternative to full metal bracelets. While the 42mm case size is occasionally cited as being large for smaller wrists, the watch is widely praised for its engineering excellence and its unique position as a high-complication piece within the Rolex catalog. Some critics mention the high entry price and limited availability, but overall, it is regarded as a premier choice for global travelers.
