This Rolex GMT-Master II Rolesor (two-tone) model ref: 126715CHNR features a 40 mm Oystersteel case fitted onto an Oyster bracelet with 18ct Everose gold case and a concealed folding crownclasp. The bidirectional bezel is crafted from brown and black ceramic with a cerachrom insert. The dial is black with luminescent white hour markers that are polished with 18ct Everose gold to prevent tarnishing. Its power comes from the self-winding caliber 3285, and this movement allows travellers to easily adjust their local time by winding the crown without stopping the watch or affecting the 24-hour time hand. This unworn watch comes with the original box and papers, a 2-year Cagau warranty, and the time remaining on the manufacturer's warranty.
