Franck Muller’s $2.7 million Aeternitas Mega 4 – the most complicated wristwatch in the world

Franck Muller‘s Aeternitas Mega 4 is 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 4 that follows a 1000 year cycle renewable to infinity.

The challenge for the Master Watchmakers of Genthod was enormous: how to embed all the complications known to this day in a watch that was designed to be worn. The Aeternitas movement served as a base, while the Mega 4 represents the apotheosis of the art of watchmaking with its grand and small Westminster chime striking-work, the only one available on the market with a tourbillon visible on the dial.
