Rolex Cosmograph Daytona Oyster, 40 mm

A key part of the model’s identity is the bezel moulded with a tachymetric scale for measuring average speeds of up to 400 miles or kilometres per hour. This model features a white dial with snailed counters, gold applique hour markers and hands with a Chromalight display, a highly-legible luminescent material. Rolex uses Oystersteel for its steel watch cases. Specially developed by the brand, Oystersteel belongs to the 904L steel family, alloys most commonly used in high-technology and in the aerospace and chemical industries, where maximum resistance to corrosion is essential.
