The brown and black bezel is the entire identity of the 126711CHNR. Collectors call it “Root Beer” — a nickname earned from the warm two-tone colorway that Rolex first introduced in the 1960s on earlier GMT references and revived in 2018 with modern Cerachrom ceramic. This version pairs Everose Rolesor (Oystersteel and 18ct Everose gold) with the current-generation 40mm case, making it one of the few GMT-Master II references that mixes precious metal with steel.

The 126711CHNR Up Close: Case, Dial and Bracelet
Look at the bezel first — that is what buyers of this reference are buying. The bi-color Cerachrom insert transitions from brown (upper half, representing daytime hours 6-18) to black (lower half, nighttime 18-6) with a 24-hour graduated scale. Unlike painted or anodized aluminum bezels from earlier generations, the Cerachrom colors are baked into the ceramic itself, which means they will not fade from UV exposure. The bezel rotates bidirectionally and locks against the GMT hand to read a second time zone.
The 40mm case blends Oystersteel sides with Everose gold on the crown, crown guards, and center bracelet links. The black dial keeps things legible — applied Chromalight markers, a green-tinted GMT hand that points to the 24-hour bezel scale, and a date window at 3 with the Cyclops magnifier. The GMT-Master II collection includes several bezel colorways, but the Root Beer stands apart because the warm brown tone changes character dramatically depending on ambient light — nearly chocolate indoors, copper-tinged in direct sun.
Movement Options: Swiss vs Japanese
A GMT watch lives or dies by its independent hour hand. This is the function that lets you track a second time zone without disturbing the minute and seconds hands. Both movement options here deliver that capability, but differently.
- Swiss Automatic — References the genuine Caliber 3285. 28,800 vph, approximately 70-hour power reserve. The independent hour hand jumps in one-hour increments when you pull the crown to position two and rotate, allowing quick adjustment when crossing time zones. Hacking seconds and quickset date function as expected.
- Japanese Automatic — Miyota-based, 21,600 vph, approximately 40-hour power reserve. The GMT hand is functional. Hacking and quickset date included. Any watchmaker with standard tools can service this movement without sourcing proprietary parts.
Both options run automatically via bidirectional rotor. The Swiss movement more closely replicates how the genuine 3285 handles time-zone changes — specifically the jump-hour mechanism and the longer power reserve for travel scenarios where the watch may sit unworn for a day or two.
