Sky‑Dweller White Gold Oysterflex

Rolex Sky‑Dweller 336239 White Gold Oysterflex

The Rolex Sky-Dweller – Ref. 336239 represents the brand’s most sophisticated travel watch, combining an advanced annual calendar and dual-time functionality with refined precious-metal construction. Crafted from 18 ct white gold, the watch features a 42 mm Oyster case paired with the signature fluted Ring Command bezel, a unique Rolex innovation used to select the movement’s setting functions.

The white dial displays the Sky-Dweller’s distinctive layout, with an off-centre 24-hour disc that allows easy reading of a second time zone. Around the dial’s periphery, 12 small apertures indicate the months of the year, forming part of Rolex’s Saros annual calendar system, which automatically differentiates between 30- and 31-day months, requiring adjustment only once per year in March. The classic date window at 3 o’clock is magnified by the signature Cyclops lens (2.5×).

The robust Oyster case architecture integrates a Triplock screw-down crown, scratch-resistant sapphire crystal, and a solid screw-down caseback, ensuring 100 meters of water resistance. This reference is fitted with the innovative Oysterflex bracelet, which combines the durability of a metal blade core with the flexibility of high-performance elastomer, offering exceptional comfort while maintaining the appearance of a sporty rubber strap.

Inside beats the in-house Rolex Calibre 9002, an advanced self-winding movement composed of approximately 380 components and 40 jewels. Operating at 28,800 vibrations per hour (4 Hz), it incorporates the Chronergy escapement, blue Parachrom hairspring, and Paraflex shock absorbers for improved efficiency and durability. The movement provides hours, minutes, seconds, dual time zone, instantaneous date, and annual calendar functions, supported by a 72-hour power reserve and certified Superlative Chronometer precision of −2/+2 seconds per dayafter casing.

The watch is secured by an Oysterflex bracelet with Oysterlock safety clasp and Easylink 5 mm comfort extension, ensuring a secure and comfortable fit.
