This Rolex GMT-Master II model ref: 126710BLNR features a 40 mm Oystersteel case fitted onto a Oyster bracelet surrounding a high legibility black dial. It comes with a 24-hour bi-directional rotating bezel with an arrow-tipped hand, which functions as a second-hour hand that rotates every 24 hours. This model is commonly referred to as ‘The Batman’ simply because of its Cerachrom bezel insert in blue and black ceramic, black dial, and Oyster bracelet. This unworn watch comes with the original box and papers, a 2-year Cagau warranty, and the time remaining on the manufacturer’s warranty.
