ROLEX Sky-Dweller – Ref. 336239 – 18K White Gold – Black Dial – Box & Papers – Bj-2023 – New-Like

We are proud to present this commanding Rolex Sky-Dweller—a true masterpiece of modern horological engineering and the most sophisticated timepiece in Rolex’s current collection. Dating to 2023, this example seamlessly blends the technical prowess of a world traveler’s watch with the timeless appeal of a stainless steel sports icon

Crafted in 18K white gold,  this reference 336239 is distinguished by its bi-directional fluted Ring Command bezel. This ingenious system forms a mechanical interface with the movement, allowing the wearer to select between the winding, date, local time, and reference time-setting positions simply by rotating the bezel—eliminating the need for multiple pushers and preserving the watch’s clean, elegant profile.

The black sunray dial provides a striking, high-contrast canvas for the Sky-Dweller’s highly legible dual time display. The centrally mounted hands indicate local time, while an off-center 24-hour disc clearly differentiates between day and night in the reference time zone—an essential feature for frequent travelers.

A defining element of the Sky-Dweller is its Saros annual calendar, named after the astronomical cycle governing eclipses. This sophisticated mechanism uses a planetary gear system to automatically distinguish between 30- and 31-day months. The current month is discreetly indicated by a red marker within one of twelve apertures around the dial, offering exceptional clarity without disrupting the dial’s symmetry. Only a single manual correction is required each year at the end of February.

At the heart of this timepiece lies the Rolex Caliber 9001, one of the most complex movements ever engineered by Rolex. Its advanced gear train architecture allows for independent and rapid adjustment of the local hour hand in one-hour increments—both forwards and backwards—without stopping the seconds hand or disturbing the reference time. This “jumping hour” function also drives instantaneous date changes, both forwards and backwards, providing exceptional convenience when crossing time zones.

“The Sky-Dweller Ref. 336239 is the ultimate expression of Rolex innovation—seamlessly integrating a sophisticated annual calendar and dual-time function into a design that remains as intuitive to use as it is impressive to behold.”
