The Sky-Dweller is one of Rolex's most complex collections: a men's wristwatch for frequent travellers, first released in 2012. Its 42 mm Oyster case houses the Saros annual calendar, a second time zone on an off-centre 24-hour disc and the fluted Ring Command bezel. All functions are set via the bezel, so there are no extra pushers on the case. Two other Rolex lines carry similar names — the Sea-Dweller and the Land-Dweller — and are separate collections.
The main choices are case metal, bracelet and calibre generation. Options include Oystersteel combined with white or yellow gold, Everose gold and white gold. Bracelets are Oyster and Jubilee; there is also the Oysterflex rubber strap and, occasionally, a leather strap. Dials come in blue, black, white, green, chocolate and champagne, as well as silver with Roman numerals. Earlier references use calibre 9001, later ones calibre 9002.
Condition ranges from new and unworn to good, and years of production from 2013 to 2026. Each listing gives the reference, calibre, power reserve, condition and what is included.
