The bold contrast between the dial colour and the subsidiary dials makes this model instantly recognisable and as such it has long been lauded as a design icon. Both references 6263 and 6265 were launched in 1969, thus replacing the first Oyster Cosmograph 6240. The 6263, a stainless steel model with screw-down pushers remained in production for nearly 20 years. This year, Rolex celebrates the 60th Anniversary of this iconic chronograph.
