This is a high-performance barrel. This component stores then distributes the necessary energy to the calibre in optimal fashion. Conceived and made in-house, it has been constantly improved, down to the finesse of its walls and surfaces. When active, its mainspring coils around the arbor and converts the Perpetual rotor’s rotations to a power reserve of up to 72 hours. This energy is then distilled with regularity and stability, regardless of wearer activity level. Channeling tension to master the art of release. Discover more https://on.rolex.com/3YL8G2q
