This configuration is commonly known among collectors as the “Batman.” Rolex confirms the 126710BLNR as a 40 mm Oystersteel GMT-Master II powered by the manufacture Calibre 3285.
Description
The Rolex GMT-Master II “Batman” is a modern interpretation of Rolex's legendary travel watch, distinguished by its striking blue-and-black two-colour Cerachrom ceramic bezel. The 24-hour GMT hand works with the bezel to display a second time zone, while the conventional hour hand can be independently adjusted when travelling.
This example features a 40 mm Oystersteel case, glossy black dial, luminous Chromalight hour markers, Cyclops date magnifier and the sophisticated Jubilee five-link bracelet. The combination of the black dial, blue/black bezel and polished Jubilee bracelet gives the watch a particularly versatile appearance—sporty enough for travel while retaining Rolex's characteristic luxury aesthetic.
