The Aeternitas Mega – the most complicated wristwatch in the world – is the pinnacle of success in the art of watchmaking in terms of complexity and complications. With 36 complications and 1’483 components, the Aeternitas Mega is a wonder of micro-mechanic and watchmaking know-how. Wholly manufactured in-house, each of the 1,483 components, was designed to give the watch an elegant design in the pure traditions of the old “cadraturiers” of the Vallée de Joux. The name of the Aeternitas comes from Latin and means eternity. It is in tribute to the eternal calendar in the Aeternitas Mega that follows a 1000-year cycle renewable to infinity.
