Rolex introduces two new versions of the Oyster Perpetual GMT-Master II that signal the return of 18ct yellow gold to the model. The first is a yellow Rolesor version – combining Oystersteel and yellow gold – whereas the second is crafted entirely in this precious metal. Both share common features. Firstly a two-colour, 24-hour graduated monobloc Cerachrom bezel insert in grey – a new shade – and black ceramic. These new versions are fitted exclusively on a Jubilee bracelet, equipped with an Oysterlock safety clasp and the Easylink comfort extension link. They are driven by caliber 3285, a movement at the forefront of watchmaking technology.
