ROLEX GMT MASTER II "BATMAN" This Rolex GMT Master II features a superb cal. 3186 (with parachrom hairspring and Breguet overcoil), a lacquer dial and white gold Chromolight appliques, but its most impressive asset is the bezel.
The GMT has long been known for its iconic two-tone bezel, to differentiate day and night, but this is the first full-production outing in blue and black.
Moreover, it's made of a single block of cerachrom, using a patented process that makes it the first watch to feature ceramic components in multiple colours.
The material starts as entirely blue and the black colouring is added to the appropriate half while the substance is still porous.
