A chronograph made for the race circuit
The Cosmograph Daytona is equipped with calibre 4130, a self-winding mechanical chronograph movement entirely developed and manufactured by Rolex, offering a power reserve of approximately 72 hours. This movement incorporates a chronograph function with a reduced number of components, thereby further enhancing its reliability. The chronograph is engaged by a mechanism with a column wheel and vertical clutch. This enables an instantaneous and extremely precise start to the timing.
