50 | CALIBER V – THE MOVEMENT CALIBER V FOR KONRAD & HEINRICH The fourth movement presented by LANG & HEYNE shows another look than its ancestors. The gracile shape of the trigonal bridge is revealing: Chamfered spokes wheels in solid gold, the huge balance with the characteristically L&H design, the fine moustache anchor and last but not least the exciting highlight of the CALIBER V, the mechanism of the constant force. Its position is the escapement wheel, the last part of the wheel train, and it makes sure that the balance receives the same force bit by bit. This compensates the mainspring’s irregular force-curve and tolerances of the wheel train. The result is a constant amplitude of the balance for the whole running time and an enhanced accuracy. The complicated lever mechanism of the prograde (forward jumping) date indication is positioned under the dial and invisible to the eyes.
