Collectors dubbed the 126713GRNR “Bumblebee” for its vivid green-and-black Cerachrom bezel pairing. Released as part of Rolex’s continued expansion of the GMT-Master II palette, this reference combines the sporty utility of a dual-timezone complication with the refined comfort of a five-link Jubilee bracelet — a configuration that has quickly become one of the most sought-after in the modern GMT range.

The 126713GRNR Up Close: Case, Dial and Bracelet
The 40mm Oystersteel case tapers from broad lugs into a polished mid-case band, balancing visual weight with wearing comfort. The green upper half of the Cerachrom bezel represents daytime hours while the black lower half marks nighttime, enabling quick GMT reading at a glance.
A black lacquer dial carries Chromalight indices that emit a long-lasting blue glow in darkness. The Jubilee bracelet, with its five-link profile and concealed Crownclasp, provides a dressier silhouette than the Oyster option.
