Rolex Cosmograph Daytona
The triumph of endurance

The Cosmograph Daytona is equipped with calibre 4131. This chronograph movement, entirely developed and manufactured by Rolex, is an evolution of calibre 4130. Unveiled in 2023, it incorporates a number of the major innovations that Rolex has brought to its movements, including the Chronergy escapement, Paraflex shock absorbers and an optimised ball bearing.

This calibre features a cut-out oscillating weight and, on the bridges, an exclusive Rolex Côtes de Genève decoration – a reinterpretation of an iconic finishing in traditional Swiss watchmaking.

On the version in 950 platinum, recognisable by its ice blue dial, the oscillating weight is made from yellow gold and is visible to the wearer through the transparent case back in sapphire.

The 18 ct gold versions of the Cosmograph Daytona featuring a Cerachrom bezel are exclusively available with an Oysterflex bracelet. Developed by Rolex and patented, it singularly combines the robustness of a metal bracelet with the comfort of an elastomer bracelet. Equipped with an Oysterlock safety clasp, which prevents accidental opening, its length may be adjusted via the ingenious Rolex Glidelock extension system.
