renaming the firm "Breguet et Fils" (Breguet and Sons). Louis-Antoine took over the firm upon the death of his father in 1823. After Louis-Antoine retired in 1833 (he died in 1858) the business was passed to Abraham-Louis' grandson Louis Clément Francois (1804–1883). Abraham-Louis' great-grandson Louis Antoine (1851–1882) was the last of the Breguet family to run the business. Although he had two sons and a daughter, they did not enter the business, so the Breguet company hired noted English watchmaker Edward Brown of Clerkenwell to manage the Paris factory. Brown eventually became a partner and, after Breguet's grandson's death, the owner and head of the company. When Brown died in 1895 the firm was taken over by his sons, Edward and Henry. On Edward's retirement in the early 1900s, Henry Brown became the head of the firm. Recent development From 1870 to 1970, Breguet was owned by the English Brown family. The Brown family were of English origin, Edward Brown was prominent factory manager who acquired Breguet from Abraham-Louis’ grandson, Louis-François, an engineer. Brown managed the brand through the turbulent French politics of the late 19th century. It was only after Edward’s death that the firm saw its sales rise near the levels it enjoyed before 1870. Edward’s son, Edouard, took over the business until 1912 when his brother Henry took over. After the Brown family, the ownership changed hands several times during the quartz crisis in the 1970s and 1980s. In 1976, Breguet's then-owner Chaumet closed its French factory and moved production to the Vallée de Joux in Switzerland. In 1987, Breguet was acquired by Investcorp which, in 1991, created the Groupe Horloger Breguet (GHB). The Breguet Group consists of four subsidiaries: Montres Breguet SA, Breguet SA, Valdar SA and Nouvelle Lemania SA (which Breguet Group acquired in 1992). As a result, Breguet-brand watches are now made at the Nouvelle Lemania factory in Switzerland. In particular, Montres Breguet SA is the main company that sells timepieces under the brand name of "Breguet", and Breguet SA is the name of Breguet Group's distribution company in France. In 1999, Groupe Horloger Breguet was acquired by the Swatch Group from Investcorp. Breguet is an active member of the Federation of the Swiss Watch Industry FH. Motto and slogan One of Breguet's company mottoes is "In every woman is a queen." The motto was introduced for Breguet's lady's collection, the Reine de Naples
