The Rolex GMT-Master II 126710BLNR-0003 pairs the black and blue bezel that defines the Batman with the simplicity of the Oyster bracelet. It is a combination that suits the GMT-Master II particularly well, keeping the focus on the bezel and the travel watch functionality at the heart of the collection. The BLNR colourway first appeared in 2013, becoming the first GMT-Master II to combine black and blue ceramic. On the 40mm Oystersteel case, the two colours sit naturally against the black dial, with the blue GMT hand carrying the same accent through to the display. It is a relatively simple combination, but one that gives the Batman an identity quite separate from the other modern GMT colourways. The Oyster bracelet plays an important role in this reference. Its broader three piece construction gives the 126710BLNR-0003 a cleaner, sportier profile than the Jubilee equipped Batgirl, putting greater emphasis on the case and bezel. It also gives the watch a more straightforward appearance that feels particularly well suited to everyday wear. Power comes from Rolex’s calibre 3285, offering an independently adjustable local hour hand and approximately 70 hours of power reserve. The functionality is designed around travel, but the enduring appeal of the Batman comes from how easily that purpose translates into an everyday watch. This 2021 example is presented in excellent condition, showing only light signs of wear and remains unpolished. Offered as a complete set, including its 2021-dated warranty card, booklet, both tags and original Rolex box. We welcome viewings in our Knightsbridge showroom.
