Rolex Sky-Dweller White Gold 42mm White Dial – Ref. 336239 on Oysterflex Strap

A contemporary marvel of Rolex engineering, the Rolex Sky-Dweller Ref. 336239 blends cutting-edge functionality with refined elegance. Crafted in 18k white gold and featuring Rolex’s innovative Oysterflex strap, this timepiece is the pinnacle of sporty sophistication, built for global travelers who demand both luxury and technical prowess.

The 336239 features a commanding 42mm case made entirely from solid 18k white gold, showcasing Rolex’s superior mastery of precious metals. The polished and satin-finished surfaces transition seamlessly into the iconic fluted bezel, which is not merely decorative—it functions as part of the Ring Command System, used to set the calendar and dual time zones.

One of the standout features of this model is its use of the Oysterflex bracelet, a Rolex-patented elastomer strap over a flexible metal blade for optimal durability, comfort, and longevity. The strap includes an 18k white gold Oysterclasp with the Glidelock extension system for fine adjustments. 

The striking white dial provides excellent legibility and houses a wealth of functionality. At the center is an off-center rotating disc displaying a 24-hour second time zone, while an annual calendar displays the month via small apertures at each hour marker and the date in the familiar window at 3 o’clock.

Inside the 336239 ticks the new Rolex Caliber 9002, a next-generation automatic movement engineered in-house. This updated caliber is based on the 9001 and includes Rolex’s latest Chronergy escapement for improved efficiency and precision. The annual calendar complication automatically adjusts for months with 30 or 31 days, requiring only one correction per year—in February.
