About the Rolex GMT-Master II 126713GRNR
The GMT-Master II was originally developed in partnership with Pan American World Airways as a tool watch for professional pilots who needed to track two time zones simultaneously, and the line has evolved into one of the most desirable luxury sport watches on the market. The reference 126713 represents Rolex's modern two-tone Rolesor iteration of the GMT-Master II, combining an Oystersteel case and bracelet with 18k yellow gold accents and crown guards. The black and green "Sprite" bidirectional 24-hour graduated Cerachrom bezel insert is a defining visual element, rendered in scratch-resistant ceramic that retains its color against UV exposure. Powered by a Rolex in-house movement with a true independent GMT hand, the 126713GRNR offers the technical functionality that made the GMT-Master II a professional standard.
What to Look For
When shopping for the 126713GRNR, pay close attention to the bracelet designation: references ending in RBJ indicate the five-piece Jubilee bracelet, which is the configuration Rolex pairs with this reference as standard and is the most sought-after presentation for this model. Condition of the two-tone Rolesor case, integrity of the Cerachrom bezel insert, and presence of original box and papers all meaningfully influence value, and buyers should confirm that the black dial, cyclops lens date window, and luminous hour markers are consistent with factory specification.
Frequently Asked Questions
What does the reference number 126713GRNRBJ mean?
The reference 126713GRNR identifies this as a two-tone steel and yellow gold GMT-Master II with a black and green ceramic bezel, while the suffix RBJ denotes the Jubilee bracelet configuration. The variant 126713GRNRBJ1 reflects a sub-configuration distinction within the same reference, typically related to dial or bracelet details as catalogued by Rolex authorized dealers.
Is the 126713GRNR the "Sprite" GMT-Master II?
Yes, the nickname "Sprite" refers to the black and green color combination of the Cerachrom bezel insert on the 126713GRNR, drawing a playful parallel to the well-known soft drink's branding colors. This colorway was introduced on the two-tone Rolesor model and has become one of the most recognized and collected configurations in the modern GMT-Master II lineup.
Why buy the two-tone 126713GRNR instead of the all-steel or all-gold version?
The two-tone Rolesor configuration of the 126713GRNR offers a middle ground between the sportier all-steel GMT-Master II models and the more formal full yellow gold references, making it versatile across a range of wearing occasions. The yellow gold accents on the bezel, crown, and Jubilee bracelet center links add warmth and collectibility while keeping the watch accessible relative to the price of a full precious-metal reference.
