Calibre 4130 is an automatic chronograph movement by Rolex.


Self-winding chronograph movement, rotor bi-directional winding, 28,800 A/h, 44 jewels, Kif shock protection, power reserve 72 hours.

The movement has been developed for the model Cosmograph Daytona, in which a modified El Primero chronograph movement by Zenith (called Rolex 4030) had been used before.

This was the first movement to use Rolex's Parachrom hairspring alloy when introduced in 2000.
