Launched in 2009 the Zeitwerk collection famously pays homage to the Dresden Semper Opera house with 5 minutes digital display clock. Disruptive with its unconventional design the Zeitwerk is powered by a constant force mechanism (remontoire d’egalite) enabling and uniform flow of energy to power the jumping hour and minute discs of the brand’s signature time bridge display. Extremely easy to operate by the push of a button the game changing Zeitwerk caught the attention of aficionados.
