The GMT-Master is Rolex's original airline watch: a fourth hand, a 24-hour bezel, and two time zones on the wrist.

			The fast map is simple: bakelite 6542 first, the long 1675 vintage core second, quick-set five-digit GMT-Master references third, independent-hour GMT-Master II from 1982, and ceramic GMT-Master II from 2005. Pepsi, Root Beer, Coke, and black then become the family's own collector language.

	The case moved to a narrower geometry than the Super Case that came before it, roughly 11.9–12.5mm thick depending on case material. Fratello puts the 126710BLNR at 12.5mm against the thicker 116710BLNR.

Coke belongs mainly to the GMT-Master II era from the [[Reference:16760\|16760]] onward. Gold and two-tone watches are part of the main line from early on, not side branches.
