The present model incorporates a co-axial escapement, invented by the contemporary horologist George Daniels. Its design is based on the double Co-Axial escape wheel, a lever with three pallet stones and impulse stone on the balance roller, together with a free sprung balance. Compared with the lever escapement, the Co-Axial system reduces sliding friction and consequently ensures greater accuracy over time.
