Rolex Cosmograph Daytona
An icon eternally revisited

The first version, fitted on an Oysterflex bracelet, features a dial in white mother-of-pearl with chronograph counters in black mother-of-pearl. The colour combination is reversed on the second watch, which has an Oyster bracelet and a black mother-of-pearl dial with white mother-of-pearl counters. This design called for the creation of a specific and technically demanding manufacturing process. 

The Cosmograph Daytona is equipped with calibre 4131, entirely developed and manufactured by Rolex, which features bridges decorated with Rolex Côtes de Genève and a cut-out oscillating weight. Calibre 4131 enables the Cosmograph Daytona to measure intervals of time via the chronograph function, in addition to displaying the hours, minutes and seconds.

The Cosmograph Daytona is driven by calibre 4131, a chronograph movement entirely developed and manufactured by Rolex. Released in 2023, it was introduced on the model the same year and exclusively equips this watch. It incorporates a chronograph function with a reduced number of components, thereby also enhancing the movement’s reliability. It is engaged by a robust mechanism with a column wheel and vertical clutch, allowing an instantaneous and extremely precise start. Calibre 4131 demonstrates carefully finished aesthetics, notably on the bridges, which feature Rolex Côtes de Genève – a decoration that differs from traditional Côtes de Genève for the slight polished groove between each band.
