Frank Muller (1918-1989), German physicist

Franck Muller is a Swiss watch brand founded in 1992 and based in Genthod, near Geneva. Even before the brand was founded, Franck Muller began releasing a watch every year under the name "Franck Genève". While the tonneau-shaped case and exaggerated indexes are Franck Muller's trademark, the brand is also a master of watchmaking, with the Aeternitas Mega 4, released in 2007, being one of the world's most complicated wristwatches.
