The Rolex Calibre 4130-540 Reversing Wheel (OEM Part No. RP4130-540R) is an OE-spec component engineered for the iconic Rolex Calibre 4130 automatic chronograph movement. Patented by Rolex in 1952, this reversing wheel coordinates with its counterpart to transmit rotational energy from the oscillating weight to the mainspring, regardless of the rotor’s direction of rotation. Featuring a distinctive red surface treatment introduced in 1957—originally applied to aluminium for enhanced robustness—this high-stress component plays a critical role in the movement’s bidirectional automatic winding system.
As a Genuine OEM Part meticulously manufactured to the original factory specifications, it ensures seamless drop-in compatibility, making it essential for professional watchmakers requiring an exact-match replacement when servicing a worn or damaged original.
OE-spec manufacturing – Precision-engineered to original Rolex tolerances for Calibre 4130, ensuring drop-in replacement fitment.
Efficient bidirectional winding – Works in pair with the matching reversing wheel to continuously transmit energy to the mainspring regardless of rotor direction, improving winding efficiency by 68% over previous calibers.
High-durability design – Withstands constant high stress; features a hardened surface treatment for excellent wear resistance over long-term use.
Iconic red finish – Distinctive red colouration makes it easily identifiable inside the movement, serving as a visual signature of Rolex’s automatic winding system.
Precise fit for Calibre 4130 – Exclusively designed for the 4130 movement found in Oyster Perpetual Cosmograph Daytona watches, integrating seamlessly with the entire mechanism.
