Franck Muller began his watchmaking career restoring watches for collectors and auction houses, gradually building a reputation for his skill in restoring complicated timepieces. Becoming one of the most sought-after restorers, he worked on the maintenance and restoration of watches in the Patek Philippe collection, many of which sit in the Patek Philippe Museum today.
In 1984, Muller designed his first tourbillon wristwatch, at a time when the complication was scarce. The tourbillon in wristwatch form only really came into being in the following years, with Muller claiming the first-ever exposed, dial-side tourbillon with this piece. A few years later, in 1991, he would form his eponymous brand, with the title "Master of Complications", looking to offer distinctive pieces to collectors.
