Built around a 42mm 18K yellow gold case, this Sky-Dweller features a screw-down back and a screw-down crown with Twinlock double waterproofness, delivering water resistance to 100 metres / 330 feet. The fluted, bidirectional rotatable Ring Command bezel frames a scratch-resistant sapphire crystal fitted with a Cyclops lens over the date.
The bright black dial is laid out with index hour markers and carries a 24-hour display on an off-centre disc for a second time zone, while 12 apertures around the dial circumference provide a continuous month display and an instantaneous annual calendar at 3 o'clock. Centre hour, minute, and seconds hands are complemented by stop-seconds for precise time setting.
Power comes from the Rolex manufacture Perpetual self-winding calibre 9002, offering dual time zones, an annual calendar, rapid date setting, and approximately 72 hours of power reserve. The Oyster bracelet is composed of three-piece solid links secured by a folding Oysterclasp buckle with an Easylink 5mm comfort extension. This example is new and includes the original box and papers.
