[1][6][7][8][9] Over the years, notable Breguet patrons and timepiece owners include Emperor of the French Napoléon Bonaparte, King George III, Queen Victoria, Alexandre I of Russia, Ettore Bugatti, Sir Winston Churchill, Sergei Rachmaninoff, Gioachino Rossini, Arthur Rubinstein and so on.

The dowry that came with his marriage to the daughter of a prosperous French bourgeois provided the backing which allowed him to open his own workshop.

Breguet's connections made during his apprenticeship as a watchmaker and as a student of mathematics helped him to establish his business.

After Louis-Antoine retired in 1833 (he died in 1858) the business was passed to Abraham-Louis' grandson Louis Clément Francois (1804–1883).

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.

In 1976, Breguet's then-owner Chaumet closed its French factory and moved production to the Vallée de Joux in Switzerland.

[27] In addition to watches, Breguet also manufactures writing instruments, women's jewelry, and cufflinks.

In December 2018, World Wide Fund for Nature (WWF) released an official report giving environmental ratings for 15 major watch manufacturers and jewelers in Switzerland.

[44] There are concerns over the lack of transparency in manufacturing activities and the sourcing of precious raw materials such as gold, which is a major cause of environmental issues such as pollution, soil degradation and deforestation.

[44][45] The situation is especially serious in the developing countries which are top producers of gold, including China, Russia and South Africa.

[19][20] The requirement was that the watch should be "as spectacular as possible, incorporating the fullest range of horological expertise known at the time".
