About the Cosmograph Daytona
Born in 1963 for professional racing drivers, the Cosmograph Daytona pairs a chronograph with a tachymetric bezel for measuring average speeds. The 40mm steel and gold references of the late 2010s carried the respected calibre 4130 column-wheel movement, while the 2023 generation introduced calibre 4131 with a longer power reserve and the Cerachrom monobloc bezel. Everose gold versions, whether on Oysterflex or bracelet, sit at the warmer, rarer end of the Daytona range.
