Rolex Calibre 4131
The new Rolex Cal. 4131 is a brand-new self-winding chronograph movement. It is the most recent evolution of the iconic 4130 calibre. It comes with in-house innovations like Chronergy escapement, blue Parachrom hairspring, Rolex overcoil, and Paraflex shock absorbers. Powered by an oscillating weight with an optimized ball bearing system, it provides a power reserve of 72 hours.
The brand has also carried out some aesthetic refinements on the new calibre, such as cut-out oscillating weight and the exclusive Côtes de Genève decorations on the bridges. The special oscillating weight of the new platinum Daytona is made of 18K yellow gold where as other versions have standard rotors fitted with Cal. 4131.
Moreover, this movement offers chronograph function with a reduced number of components, thereby also enhancing the movement’s reliability. Its column wheel and vertical clutch system allows an instantaneous and extremely precise start. The special Côtes de Genève decoration applied on the movement bridges differs from the traditional Côtes de Genève by the addition of a slight polished groove between each band.
