Heritage Narrative
The Rolex GMT-Master II has been the definitive traveler’s watch since its debut in 1955, created for Pan Am pilots to track multiple time zones across continents. The reference 126710BLNR, known affectionately as the “Batman,”updates that aviation legacy with Rolex’s latest-generation movement and the distinctive black-and-blue Cerachrom bezel — a design that perfectly blends professional utility with modern elegance.
This 2023 example, presented in mint condition, features a 40 mm Oystersteel case paired with a matching Oyster bracelet, and the iconic bi-color ceramic bezel insert representing day and night. The black lacquer dial offers superb legibility, enhanced by Chromalight luminescence and the signature blue 24-hour GMT hand. Inside, the Calibre 3285movement delivers exceptional performance, offering a 70-hour power reserve and resistance to shocks and magnetism thanks to Rolex’s Chronergy escapement. Offered with full box and papers and under international Rolex warranty until April 2028, this piece embodies the perfect fusion of precision, durability, and cosmopolitan style.
