The only son of the founder, Antoine-Louis Breguet, takes over the company in 1824. Having been immersed in watchmaking since his earliest childhood, he pursues the work of his famous father. It is his son, Louis-Clément, who breathes a new dynamism into Breguet, understanding that watchmaking is from that point on spread through all social classes. He decides to extend his activities by diversifying, particularly in physic instruments.
"Danglars’ watch, a masterpiece by Breguet which he had rewound with care before setting out the previous day, chimed half past five in the morning."Alexandre DumasThe Count of Monte Cristo, 1844
Alexandre Dumas the elder (1802-1870), the most prolific (with nearly 300 works) and popular writer of his time, made another reference to Breguet watches in The Count of Monte Cristo, published in 1845:'Mattre Pastrini drew from his fob a magnificent Breguet watch, bearing the name of its maker, the Paris stamp and a count's coronet. "There," he said. "Dear me," said Albert, "I congratulate you upon it; I have one almost the same." He took his watch out of his waistcoat, "And it cost me three thousand francs".'Alexandre Dumas. The Count of Monte Cristo, 1845.
