The Rolex GMT-Master II Ref. 126713GRNR, affectionately nicknamed the “Zombie” by collectors, is a bold and distinguished evolution of the iconic travel watch, masterfully blending the warmth of two-tone yellow gold with a striking, understated grey and black bezel . Introduced at Watches & Wonders Geneva in 2023, this 40mm timepiece in Yellow Rolesor (a harmonious combination of Oystersteel and 18k yellow gold) marks the return of yellow gold to the GMT-Master collection after a significant hiatus . The watch features the brand’s signature bidirectional rotatable bezel fitted with a scratch-proof grey and black Cerachrom ceramic insert—a subtle yet dramatic departure from traditional blue-red or blue-black bezels—whose raised numerals and graduations are coated in yellow gold using a patented PVD process, offering a sophisticated, stealthy aesthetic that evokes a dark, mysterious character .

The black lacquer dial provides a deep, lustrous backdrop for the yellow gold-framed hour markers and the iconic Mercedes hands, all generously filled with Chromalight luminescent material for exceptional legibility in any environment . A discreet date window at 3 o’clock, magnified by the signature Cyclops lens, maintains the dial’s clean, balanced aesthetic, while the gold GMT hand circles the dial once per 24 hours, corresponding perfectly with the bezel to track a third time zone . At its heart beats the cutting-edge in-house Caliber 3285, a self-winding mechanical movement that represents the pinnacle of Rolex’s innovation, featuring the efficient Chronergy escapement and a blue Parachrom hairspring, delivering a robust 70-hour power reserve and Superlative Chronometer certification for precision exceeding official standards .

The watch is presented on the five-piece link Jubilee bracelet, which masterfully combines polished 18k yellow gold center links with satin-brushed Oystersteel outer links, celebrated for its exceptional comfort and elegant drape on the wrist, secured by an Oysterlock folding clasp with the convenient Easylink 5mm comfort extension link . Protected by a scratch-resistant sapphire crystal and housed within a hermetically sealed Oyster case with a Triplock screw-down crown, the GMT-Master II 126713GRNR offers practical 100-meter water resistance . This reference, nicknamed the “Zombie” for its dark and mysterious color scheme, is a perfect synthesis of aviation heritage, two-tone prestige, and technical excellence, making it an indispensable statement piece for the discerning traveler who demands a watch that is as mechanically sophisticated as it is visually captivating—a true modern icon that offers quiet authority on the wrist .
