Franck Muller Watches. Founded in 1991 by young watchmaker Franck Muller and Vartan Sirmakes, this Swiss watch brand was dedicated to creating original complicated movements. Today, the brand operates Watchland in a restored 20th-century mansion in Genthod, a canton of Geneva, where its watchmakers work. Franck Muller is known for its Crazy Hours watches, the Cintre Curvex, and the tonneau-shaped Vanguard.
