ZEITWERK DECIMAL STRIKE | Interview with Anthony de Haas

Given its mechanical architecture, the ZEITWERK calibre offers ideal prerequisites for the integration of a striking mechanism: Every sixty seconds, a higher amount of energy is needed for advancing up to three discs of the precisely jumping numeral display.
