The quality of the gongs determines the sonority of the chiming mechanism. The alloy, the hardness, the shape, the attachment \u2013 the engineers and technologists have found the optimal solution for every detail, no matter how insignificant it may seem.

The chiming mechanism is powered by a separate spring barrel and features its own wheel train with a lever escapement that ensures the uniform operation of the mechanism.

With a milling cutter designed by Lange especially for this purpose, tiny slots are cut into the balance wheel rim right next to the bores. Later, they will expand around the threaded bores and ensure that the poising screws are firmly seated. The screws are inserted in the rim at various depths as needed to poise the balance. There, they must retain their positions and not work themselves loose.
