Haas. The house founded in Geneva in 1848 by the brothers Léopold Haas (1827-1915) and Benjamin Haas (1828-1925) is one of the oldest Swiss watch manufacturers. Later renamed Ancienne Maison B. Haas Jeune, then Haas Neveux & Co. The Haas signature has always been one of the most sought-after, thanks to the impeccable standards of the company. They gained a reputation as a manufacturer of fine chronometers, chronographs and highly complicated watches. Among their most notable creations was the ‘remontoir perpétuel à décrochement’ (perpetual winding crown) in 1867 and 1873, a perpetual calendar in 1872 and later the first ultra-thin watch movement in circa 1896.
