Rolex Sky-Dweller 42 mm bright black dial

The Oyster Perpetual Sky-Dweller is presented with an Oysterflex bracelet. Crafted from 18 ct yellow gold, this new version is the first watch from the Classic category to be fitted with this innovative bracelet made of high-performance elastomer. It also features a bright black, sunray-finish dial with hands and hour markers in 18 ct yellow gold. The light reflections on the case sides and lugs highlight the refined profile of the 42 mm Oyster case.

This new version is of course equipped with the fluted, rotatable bezel unique to the Sky-Dweller, which is used to set the watch in conjunction with the Ring Command system.

It also has a Chromalight display: the hands and hour markers are coated or filled with a luminescent material that emits a long-lasting blue glow in dark conditions.

This new version of the Sky-Dweller is equipped with calibre 9001, at the forefront of watchmaking technology.

Like all Rolex watches, the Oyster Perpetual Sky-Dweller carries the Superlative Chronometer certification, which ensures excellent performance on the wrist. The Superlative Chronometer status is symbolized by the green seal that comes with every Rolex watch and is coupled with an international five-year guarantee.
