The new, manually wound movement L122.1 addresses all expectations that are associated with the A. Lange & Söhne brand. The sapphire-crystal caseback reveals the entire scope of artisanal finissage. It includes the freehand engraving of the balance cock with the eye-catching whiplash spring. With its lateral setscrew, it can be used to precisely adjust the interaction between the pallet lever and escapement, referred to as the “beat”. Six bearing jewels are set in polished gold chatons on a three-quarter plate made of untreated German silver and decorated with Glashütte ribbing. Four of the chatons are secured with thermally blued screws. The winding train, decorated with solarisation, is visibly integrated into the plate.
Additionally, the partially visible chiming mechanism features some finish details. The gong hammers are elaborately finished with black polish and the manually bent gongs are polished as well. All bridges of the chiming mechanism are visually paired with solarisation. Among them, the bridge above the centrifugal governor is skeletonised. Generous openings reveal the most dynamic component of the movement: balanced with two mirror-polished gold weights, the centrifugal governor rotates at a speed of more than 2,000 revolutions per minute when the striking mechanism is running. This guarantees the uniform cadence of the strikes.
