Franck Muller was born in 1958. He spent his childhood in La Chaux-de-Fonds with his Italian mother and Swiss-born father. When 15, he enrolled in a watchmaking school.
In the early 1980s, he graduated from the Watchmaking School of Geneva (French: Ecole d’Horlogerie de Genève).
Afterwards he began repairing top-quality pocket watches. Close to an independent watchmaker by the name of Svend Andersen, Franck Muller became responsible for handling watches from the collection of Patek Philippe.
Most of the clientele were private individuals and museums. While he was working with complicated timepieces, he became passionate about their mechanisms and began to think of building his own workshop.
