Very rare three quarter plate movement with double locking, inverted lever chronometer escapement. circa 1860. White enamel dial. . In this escapement drawn from the Robin detent-lever, with direct impulse of the 'scape wheel on the balance staff, the double locking is provided by an inverted lever, such is that used by Girard Perregaux for his three parallel gold bridge movement. This movement appears to have the same ébauche as the previous lot.
