Franck Muller watches

Franck Muller was established as a brand in 1991 by the watchmaker Franck Muller and the casemaker Vartan Sirmakes. Before then Muller had made complicated wristwatches in small numbers, including a tourbillon wristwatch with a jump-hour display. The company's headquarters and production site, known as Watchland, is in Genthod in the canton of Geneva.

The company describes the Cintrée Curvex shape as its most significant silhouette. Its collections include Crazy Hours, Vanguard, Long Island and Aeternitas, the last including watches with 36 complications. In 2025 Europa Star described the company as family-owned, with Nicholas Rudaz as chief executive and a new generation of the Sirmakes family preparing to take over.
