The Rolex GMT-Master II Ref. 16710 “Coke” is a legendary stainless steel timepiece from the pre-ceramic era, produced between approximately 1989 and 2007, whose iconic black dial and distinctive red-and-black 24-hour bezel insert have become the cornerstone of its coveted nickname . This 40mm Oystersteel case, equipped with a bidirectional bezel and a sapphire crystal, houses the robust in-house automatic Caliber 3185 movement, which introduced the independently adjustable jumping hour hand—a key functional evolution for tracking a second time zone while delivering a reliable power reserve of about 48 hours . As the final generation of the aluminum-bezel GMT-Master II models, the 16710 offers the perfect blend of vintage charm and modern reliability, with its black “Mercedes” hands and luminous markers ensuring exceptional legibility while the solid-link Oyster bracelet provides comfortable wear . Its production span with multiple bezel variants makes the 16710 highly collectible, but the “Coke” version holds a special status as it has never been revived in Rolex’s modern Cerachrom ceramic form, cementing its value and desirability among seasoned enthusiasts . As one of the most recognizable and versatile sports models ever produced, the GMT-Master II 16710 “Coke” represents a perfect balance of heritage, functionality, and timeless style for the discerning collector. Key specifications: 40mm stainless steel case; black dial; Caliber 3185 automatic movement; approximately 48-hour power reserve; red and black “Coke” aluminum bezel insert; Oyster bracelet; 100m water resistance; sapphire crystal.
