Rather than sandwiching two different coloured pieces of ceramic next to each other, Rolex patented a process whereby a wholly blue bezel is created which is still permeable to the black colouring when it is added. The black and blue combination has fondly been nicknamed the Batman. For further information on this lot please visit Bonhams.com
