Rolex GMT-Master II 40 mm

The Rolex GMT-Master II 126710BLNR-0003, known as the Batman, is a 40 mm steel GMT watch known for its blue and black bezel. The case measures 12.1 mm thick and pairs with a black dial under a sapphire crystal with Cyclops lens over the date. A bidirectional rotatable bezel with a black ceramic insert tracks a second time zone alongside the central GMT hand, and the date sits beside a self-winding perpetual movement, calibre 3285, certified as a chronometer. Hands and indices carry luminous treatment for legibility in low light. The steel bracelet closes with a folding Oysterlock safety clasp fitted with an Easylink comfort extension link. Rolex rates the case to 100 metres.
