Chronergy

Chronergy is a patented Rolex escapement system.

It is a modification of the Swiss lever escapement, taking into account these aspects:

• Reduction of the mass of the components (skeletonization of the escapement wheel, smaller size of the pallet stones).
• Change of the geometry of the escapement mechanism.

This system was first introduced in the caliber Rolex 3255 in 2015.
