Heritage Narrative
First launched in 1955, the Rolex GMT-Master was developed for international pilots, offering the ability to read multiple time zones simultaneously. Over the decades it evolved into one of Rolex’s most coveted professional models, blending tool-watch utility with unmistakable design codes. In 2023, Rolex introduced the reference 126710GRNR, a fresh take on the classic GMT-Master II. Its defining feature is the black-and-grey Cerachrom bezel — a subtle, modern alternative to the brand’s more colorful “Pepsi” and “Batman” inserts — paired with refined case proportions and the updated calibre 3285 movement.
This July 2025 example, reference 126710GRNR, is presented in Oystersteel with a 40 mm case, black dial with Chromalight luminescence, and sapphire crystal. The automatic calibre 3285 provides a 70-hour power reserve, enhanced efficiency through the Chronergy escapement, and Rolex’s Superlative Chronometer certification. Offered unworn and complete with its full set of box and papers, it is a pristine example of one of Rolex’s most modern and versatile GMTs.
