Overview

The Rolex GMT-Master II reference 126718GRNR pairs a 40 mm 18k yellow gold case with a crisp black dial, positioning it among the most formally dressed expressions of the long-running GMT-Master II line. Powered by the in-house Calibre 3285, it delivers the independently adjustable 24-hour GMT hand that has defined the reference since the line's second generation. The combination of precious metal construction and a purposeful travel complication gives the piece a character that bridges professional utility and haute horlogerie.

History

The GMT-Master lineage traces its origins to the 1950s, when Rolex developed the original reference in collaboration with a major international airline to meet the navigational needs of long-haul crews. The second-generation GMT-Master II, distinguished by its independently settable local-hour hand, has evolved through numerous references over the decades. The 126718GRNR was introduced in 2023, bringing the Calibre 3285 — with its Chronergy escapement and 70-hour power reserve — into the yellow gold GMT-Master II family. Yellow gold variants of the GMT-Master II have historically occupied the top tier of the line, appealing to collectors who prize both technical function and precious-metal finishing.

Notable points

  • Case material is 18k yellow gold, placing the 126718GRNR at the prestige end of the GMT-Master II range.
  • The black dial creates a high-contrast, formally versatile aesthetic against the warm yellow gold case.
  • Calibre 3285 features a Chronergy escapement, a paramagnetic blue Parachrom hairspring, and an approximately 70-hour power reserve.
  • The independently adjustable GMT hand allows the local hour to be set in one-hour increments without disturbing the running seconds — a hallmark of the GMT-Master II complication.
  • Introduced in 2023, the reference represents one of the more recent additions to the GMT-Master II catalogue.
