GMT-Master → 126713GRNR

The 126713GRNR is the two-tone Rolesor GMT-Master II Rolex launched at Watches and Wonders 2023. Yellow gold had been absent from the GMT-Master II since the solid-gold 116718LN was retired in 2019, and the floor-level expectation heading into W&W 2023 was a new colour or bezel, not a return to gold. Rolex delivered both: yellow Rolesor, a new grey-and-black Cerachrom insert, and the Jubilee bracelet on a precious-metal GMT for the first time.

Nicknames came unevenly. Time+Tide’s April 2023 reader poll returned “Dark Knight” as the winner, with “Black Adam,” “Bruce Wayne,” “Guinness,” “Wolf of Wall Street,” and “Bumblebee” in the running. “Zombie” and “Bumblebee” both circulate in enthusiast and dealer copy. None has the singular grip that “Batman” or “Pepsi” earned in earlier generations.

Where it sits in the line

The 126713GRNR is the middle member of the 2023 GRNR pair, between the steel and solid-gold options. The solid-gold 126718GRNR launched on the same W&W 2023 keynote. The steel 126710GRNR arrived a year later in 2024 to complete the family. Fratello’s Sunday Morning Showdown placed the three references as steel, Rolesor, and solid gold, reading the Rolesor as the warmer middle ground and the steel as the stealthier sibling.

Rolex lists the reference under “Yellow Rolesor,” the firm’s trademark for an Oystersteel-and-yellow-gold combination in the catalogue since 1933. “GRNR” parses as gris-noir, the grey-and-black shorthand from the bezel-naming convention. The reference is not a green watch. The green-and-black Cerachrom GMT-Master II is the left-handed 126720VTNR, introduced a year earlier.

Production outline

Production began in 2023 with the W&W launch and remains current in the 2026 catalogue on rolex.com. Launch retail at introduction was EUR 16,300, CHF 15,700, and USD 16,450, per Monochrome’s hands-on review by Brice Goulard. The reference has been extended, not replaced, by the 2024 126710GRNR steel sibling.

Movement notes

The 126713GRNR runs caliber 3285. The calibre arrived on the GMT-Master II line with the 2018 126710BLRO Pepsi and carries across the whole 126710-generation family. It runs at 28,800 bph, delivers a 70-hour power reserve, and holds to Rolex’s Superlative Chronometer -2/+2 seconds-per-day standard. The Chronergy escapement is the headline mechanical change from caliber 3186, bringing higher efficiency through a redesigned pallet-fork geometry and a skeletonised escape wheel. Blue Parachrom hairspring and Paraflex shock protection carry over.

Dial map

The 126713GRNR ships with a single dial configuration: black lacquer, 18k yellow-gold applied markers, gilt-style “GMT-Master II” text, and Chromalight luminescence. The dial reads as glossy black with yellow-gold hands and markers, matching the Monochrome hands-on photography. The gilt typography is Rolex’s deliberate vintage cue. Fratello’s 2023 piece reads it as a callback to the neo-vintage two-tone Datejust and Rootbeer era, and the Jubilee bracelet reinforces the same cue.

No dial variant exists. The bezel pair is the only colour variable on the reference.

Case, bezel, crystal, and crown notes

The case is 40mm across and 11.9mm thick, with sapphire crystal and the Triplock crown. Rolex.com and Wallpaper* give matching dimensions. The case generation is the slimmer 126710 architecture that replaced the Super Case in 2019, not the bulkier 116710-era profile of the 116718LN.

The bezel is the main talking point. The grey-and-black two-colour Cerachrom insert is new. Rolex had shipped red-and-blue (BLRO), blue-and-black (BLNR), brown-and-black (CHNR), and green-and-black (VTNR) ceramic combinations before 2023, but grey-and-black had not appeared before. The numerals are recessed into the ceramic and filled with 18k yellow-gold PVD. Monochrome’s launch coverage names the insert “Gris Noir,” which decodes as GRis-NOir.

Water resistance is 100m. None of these specs depart from the broader 126710 generation.

Bracelets, end links, clasps, and packaging notes

The 126713GRNR ships on a Yellow Rolesor Jubilee bracelet with brushed steel outer links and polished 18k yellow-gold centre links. This is the first Jubilee on a precious-metal GMT-Master II, following the 2018 126710BLRO Jubilee precedent for the steel Pepsi. The Oysterclasp carries the Easylink 5mm comfort extension. Rolex’s product page confirms Jubilee as the only configuration. Full-set packaging is the standard presentation box, International Guarantee card, and swing tags.

Special branches

The 126713GRNR has no factory-level dial variants as of the 2026 catalogue. The main collector distinction is nickname rather than specification. “Zombie” emphasises the grey Cerachrom upper half and reads the watch as cool-toned. “Bumblebee” emphasises the yellow-gold-and-black combination and reads it as warm-toned. Both nicknames circulate in enthusiast copy. Time+Tide’s reader poll from April 2023 surfaced “Dark Knight,” “Black Adam,” “Bruce Wayne,” “Guinness,” and “Wolf of Wall Street” as further community proposals. None is official.

Historical market and auction record

The 126713GRNR has not yet entered the auction-house record. The reference is too recent for Sotheby’s, Phillips, or Christie’s catalogues. The auction pass remains pending.

Time+Tide’s May 2023 secondary-market snapshot is the closest market-index datapoint. First-offer grey-market asks sat around EUR 35,500 against a EUR 16,550 retail figure, roughly a 2.1x premium at first availability. That split is notable: the solid-gold 126718GRNR carried a proportionally tamer premium at the same moment, roughly 1.7x, suggesting the Rolesor variant drew stronger early demand than the all-gold sibling. Fratello’s head-to-head with the steel 126710GRNR provides the internal-family comparison.
