The Rolex GMT-Master II ref. 16710, known among collectors as the Coke for its black-and-red bezel insert, dates to 1995 and occupies a transitional place in the GMT-Master II lineage between the model's earliest steel examples and its later ceramic-bezel successors. This example presents a black dial under the aluminum 24-hour bezel, its black and red halves flanking the polished pointer used to track a second time zone via the independently adjustable 24-hour hand. The 40mm Oystersteel case retains the model's signature Oyster architecture, with a screw-down crown and caseback consistent with the line, and the dial carries the Superlative Chronometer Officially Certified designation beneath the GMT-Master II signature. Inside is an automatic-winding movement identified as caliber 3186, rated at a 50-hour power reserve, driving hours, minutes, seconds, the adjustable 24-hour GMT hand, and a date function. The watch is fitted to its steel Oyster bracelet. Excellent condition, watch only, no box or papers.
