ROLEX. A STAINLESS STEEL DUAL TIME WRISTWATCH WITH SWEEP CENTRE SECONDS, DATE AND BRACELET

Introduced at Baselworld in 2013, the Rolex GMT Master II reference 116710BLNR (for bleu, noir, French for blue, black) is the first GMT-Master to be crafted with the blue and black color combination on its bezel. A highly complicated piece to manufacture, the creation process for this Cerachrom bezel is patented and results from a singular piece of blue ceramic, with the black color later applied to provide this two-tone effect. Of additional interest, the numerals engraved on the two-tone bezel are covered with a thin layer of platinum.

Affectionately called 'Batman' by collectors due to the unique colour combination of the bezel, this timepiece is highly sought after and has become a cornerstone of contemporary Rolex sports watches. The difference between this timepiece and its counterpart, the 'Batgirl', lies in the pairing of an Oyster and Jubilee bracelet.
