The Girard-Perregaux caliber GP02700 boasts these special features - 

A unidirectional rotor with non-lubricated ceramic ball bearings.

An escape-wheel pivoting between two corresponding settings.

A swiveling balance-cock offering greater accuracy for controlling the movements of the balance. 
Providing a solution that enhances performance and long-term reliability, thus significantly assisting watchmakers when making their adjustments.
