Louis Leroy, Horloger de la Marine, started as a watchmaker for the company in 1879 and took over the business with Jules Desfontaines, changing the firm's name to L. Leroy et Cie. Louis' brother Léon Leroy, who had joined in 1895, became partner in 1914.

Leroy watches participated in various exhibitions and were awarded numerous prices, especially at chronometer contests.
