Striking mechanism Striking mechanisms make it possible for you to hear the time. The time is presented acoustically by striking gongs. In mechanical wristwatches, they pose great challenges for watchmakers. Firstly, additional parts must be integrated in the smallest of spaces while still providing enough space for the gongs to oscillate. Secondly, the striking mechanism consumes part of the timepiece’s energy.
With Lange, striking mechanisms in varying versions can be found above all in the ZEITWERK watch family. The digital jumping numerals that are typical of the family are beneficial in that the energy used to keep the numeral discs moving can partly be used for the force of the striking mechanism.
