Constant Girard (1825-1903) and Marie Perregaux (1831-1912), whose surnames united in 1854 still form the Girard-Perregaux corporate name to this day, passed the baton to their son Constant Girard-Gallet (1856-1945), who in 1906 would buy up the Old Bautte Firm. The three brothers of Marie Perregaux, Henri (1828-1893), François (1834-1877) and Jules (1838-1903) also joined the business, Henri and Jules by representing it in the Americas, and François in Asia. Constant Othenin-Girard (or Girard) began his watchmaking career initially in partnerships, under a variety of collective names. In 1854 he married Marie Perregaux (1831-1912), the product of a watchmaking family from Le Locle, and together they founded the Manufacture in La Chaux-de-Fonds which to this day bears their combined surnames (1856).
