The Cosmograph was originally designed in 1963 with attention to detail such as a highly reliable chronograph and bezel with tachymetric scale – it was structured in order to meet the demands of racing drivers. The nature of this model allows drivers to measure their speeds up to 400 kilometres/miles per hour, consequently this model has become an iconic time piece among the motoring world. The pre-owned Rolex Cosmograph models with the reference number 116520 are supplied with a year warranty.
