L. Leroy is a French haute horlogerie Maison with over 240 years of uninterrupted history. Founded in Paris in 1785 by Charles Leroy — the son of a watchmaker — the Maison was officially appointed watchmaker to the French royal family from its very inception, and later became a supplier to the imperial family. In 1835, L. Leroy was appointed watchmaker to the French Ministry of the Navy, subsequently supplying the most prestigious European naval fleets for nearly a century and a half. The Maison's crowning achievement came in 1900 when Louis Leroy presented the "Leroy 01" at the Paris Universal Exhibition, where it was awarded the Grand Prix — a piece so technically sophisticated it remained the absolute benchmark for highly complicated watchmaking until 1989. Today, L. Leroy timepieces are entirely manufactured in Geneva, embodying a philosophy devoted to the art of high complications, métiers d'art, and gem-setting. The Maison also provides a full restoration service for vintage and antique watches, dedicated to private collectors and museums.
