Rolex Sky-Dweller Yellow Gold — White Dial | Ref. 336238

Reference 336238 represents the Sky-Dweller at its most opulent — a 42 mm case rendered entirely in 18k yellow gold, housing one of the most mechanically sophisticated movements in Rolex's modern catalogue. Introduced in 2012, the Sky-Dweller was the first new Rolex complication in over a quarter century, combining an annual calendar with a dual time zone display via the distinctive off-centre ring on the dial. The white dial on this example provides a clean contrast against the warmth of the gold case, with the characteristic radial month apertures arranged around the chapter ring.

Beneath the sapphire crystal beats Calibre 9001, a self-winding movement with a 72-hour power reserve developed entirely in-house. The Saros annual calendar mechanism — named after the astronomical eclipse cycle — requires manual correction only once per year, at the end of February. The Roaminghand system displays a second time zone via a 24-hour hand, distinguishing day from night at a glance. The 42 mm Oyster case offers 100 metres of water resistance, while the Oysterflex bracelet or matching gold Oyster bracelet completes the configuration depending on specification.

For the collector, a yellow gold Sky-Dweller occupies a compelling position: it is among Rolex's most technically complex references, yet its proportions and legibility make it suitable for daily wear. The 336xxx generation brought the Calibre 9001 to the Sky-Dweller family, replacing the earlier 326xxx references and offering improved finishing. Demand consistently outpaces supply at authorised dealers, making pre-owned examples in strong condition a sensible acquisition for those seeking both horological substance and long-term value retention.
