Heritage Narrative
Since its launch in 1955, the Rolex GMT-Master has been the ultimate tool for aviators and international travelers, designed to track multiple time zones at once. Over the years it has become one of Rolex’s most desirable sport models, blending rugged functionality with distinct design codes. In 2023, Rolex introduced the reference 126710GRNR, featuring a new black-and-grey Cerachrom bezel insert — a modern, understated alternative to the colorful “Pepsi” and “Batman” variants.
This March 2025 example, reference 126710GRNR, is presented in Oystersteel with a 40 mm case, black dial with Chromalight luminescence, and sapphire crystal. Powered by the calibre 3285, it delivers a 70-hour power reserve, enhanced efficiency with the Chronergy escapement, and Rolex’s Superlative Chronometer certification. Offered unworn and complete with its full set of box and papers, it represents one of the most versatile and contemporary executions of the GMT-Master II.
