Rolex Sky-Dweller 42 mm 336933WSO Steel/Yellow Gold Luminous

The Rolex Sky-Dweller is among the most technically ambitious watches in the Rolex catalog, and reference 336933WSO represents the line at its most visually commanding. Launched as Rolex's first new complication in decades when the Sky-Dweller debuted, this model was engineered specifically for international travelers who demand both a second time zone and an annual calendar in a single, intuitive wristwatch. The 336933WSO, presented in two-tone Rolesor — Rolex's term for the combination of Oystersteel and 18 ct yellow gold — delivers that functionality wrapped in one of the sport-luxury market's most distinctive aesthetics.

At 42 mm in diameter, the Sky-Dweller wears with authoritative wrist presence without crossing into oversized territory. The Oystersteel case provides the robust foundation that Rolex's professional and sport-adjacent lines are known for, while the yellow gold elements — most prominently the fluted screw-down bezel — introduce warmth and a dressy counterpoint. The result is a watch that transitions seamlessly from a formal suit to weekend travel attire, one of the defining appeals of the Rolesor configuration.

The luminous dial ensures legibility in any light condition. Rolex's trademark luminescent material on the hour markers and hands means the Sky-Dweller's dual time-zone and annual-calendar displays remain readable whether you're crossing time zones at midnight or stepping off an evening flight. The index bracelet — widely understood as the Jubilee-style configuration offered on the Sky-Dweller — adds a further note of elegance, its five-piece links offering a supple, refined drape on the wrist that complements the watch's sport-luxury character.

The Sky-Dweller is driven by a Rolex-manufactured automatic movement, built to the exacting standards that have made Rolex movements benchmarks of reliability in the industry. The crown's Ring Command system — activated by rotating the screw-down bezel through its three positions — allows the wearer to set the home-time, local-time, and date functions independently without removing the crown, a feat of ergonomic ingenuity that sets the Sky-Dweller apart from every other annual-calendar watch on the market.
