Also known as the “Batman Rolex” or “Dark Knight”, the GMT Master II ref. 116710 is characterized by a distinctive dual-tone black and blue bezel. While the dual-tone bezel is undoubtedly striking, what makes the ref. 116710 one of the most sought-after timepieces in the Rolex catalog is the use of Cerachrom ceramic material as well as 904L Oystersteel. As collectors continue to seek stainless steel and ceramic bezel Rolex watches, the demand for this particular used Rolex will only continue to grow. The ref. 116710 also features a maxi dial with a larger luminous display, a new-style case and bracelet, and a new calibre 3186 perpetual movement with a smoother hour hand and a Paramagnetic blue Parachrom hairspring.
