History

The Sky-Dweller debuted in 2012 as Rolex's first watch to combine an annual calendar with a second time zone, and the brand's first entirely new complication design in several decades. Its most recognizable feature is the Ring Command system: the rotating bezel itself, rather than an extra pusher or crown, selects which function is being set — local time, reference (home) time, or calendar — before the crown is used.

In 2023, Rolex updated the line with a new caliber, the 9002, replacing the original 9001 from 2012. According to the sources consulted, the main change is the addition of the Chronergy escapement — already rolled out across most of Rolex's catalog for its greater energy efficiency and shock resistance — while the rest of the movement's architecture stays the same: 40 jewels, 28,800 vibrations per hour, and 72 hours of power reserve. Case dimensions — 42mm diameter, 13.80mm thickness, and 50.5mm lug-to-lug — remained unchanged from the previous generation.

The calendar function, named Saros, shows the month via 12 windows arranged alongside the hour markers, with a quick, bidirectional, and secure adjustment mechanism for both date and month. The second time zone reads off a 24-hour ring at the center of the dial, useful for travelers who need to track local and reference time simultaneously.

This Rolesor execution combines Oystersteel with a fluted, polished 18k white gold bezel, over a sunray mint green dial — also available in white, blue, and black — with white gold indices and Chromalight luminescence. With 100 meters of water resistance and an Oyster bracelet featuring ceramic inserts in the links, reference 336934 is positioned as the entry-price option within the Sky-Dweller range.
