Overview
The Rolex GMT-Master II reference 126713GRNR is a two-tone variant of Rolex's long-standing dual-time-zone sports watch, pairing a 40 mm Oyster case in Oystersteel and yellow gold with a black dial. Introduced in 2023, it carries the calibre 3285 movement and sits within the broader GMT-Master II family, a line with roots stretching back to the 1950s when Rolex developed the original GMT-Master in collaboration with Pan American World Airways. The reference continues the tradition of combining professional utility with the visual warmth of Rolesor two-tone construction.
History
The GMT-Master II line succeeded the original GMT-Master in 1983, introducing an independently adjustable 24-hour hand that allows the local hour to be set without disturbing the GMT reference. The two-tone Rolesor configuration — blending Oystersteel with gold — has been a recurring theme across GMT-Master references for decades, appealing to collectors who seek a middle ground between the full steel and full gold expressions. The 126713GRNR, introduced in 2023, represents the current generation of this pairing, updated with the modern calibre 3285 and the refined case and bracelet architecture of the contemporary GMT-Master II family.
Notable points
- Calibre 3285 features a Chronergy escapement, a 70-hour power reserve, and Rolex's Parachrom hairspring for enhanced resistance to shocks and magnetic fields.
- The Oystersteel and yellow gold Rolesor case construction is carried through to the Jubilee or Oyster bracelet, giving the watch a consistent two-tone appearance throughout.
- The black dial provides strong legibility contrast against the gilt hour markers and hands, a classic combination in the GMT-Master II range.
- At 40 mm, the case diameter sits at the long-established standard for the GMT-Master II, maintaining continuity with decades of the model's history.
- The independently adjustable local-hour hand — a defining feature of the GMT-Master II — allows wearers to track a second time zone simultaneously without resetting the main timekeeping functions.
