When the GMT-Master II made its debut in the early 1980s, Rolex equipped it with a new black and red bezel colorway. Following the soda-inspired nicknames of the blue and red "Pepsi" bezel and the brown and yellow "Root Beer" bezel, the black and red GMT bezel quickly became known as the "Coke" bezel. There have only been two references of the GMT-Master II Coke made - neither of which are in production today.

While Rolex introduced the GMT-Master in the 1950s as a way for pilots to read two time zones simultaneously, it wasn’t until 1982 that the GMT-Master II joined the lineup. Similar in style to the original GMT-Master but more technically advanced, the GMT-Master II features de-coupled 12-hour and 24-hour hands that can be set independently from each other.

The first model to kick off the collection was the GMT-Master II ref. 16760, which was also dubbed the "Fat Lady" among collectors owning to its thicker case profile to accommodate Caliber 3085. After about seven years of production, the GMT-Master II ref. 16760 was replaced by the GMT-Master II ref. 16710 in 1989.

While the GMT-Master II ref. 16760 was only available with a Coke bezel, the later GMT-Master II ref. 16710 offered the option of a Coke bezel, a Pepsi bezel, or a black bezel. Compared to its predecessor, the GMT-Master II Coke 16710 featured a slimmer case, which housed Caliber 3185 inside. Over its almost 20-year manufacturing run, the GMT-Master II ref. 16710 underwent a handful of updates including changes in luminous material, case lug holes, bracelet solid end links, and caliber.

When Rolex released the then-new six-digit GMT-Master II with Cerachrom ceramic bezels in the mid-2000s, the Coke bezel disappeared from the catalog and has not returned - yet.
