The story of Omega started in 1848 with Louis Brandt when he opened a “Comptoir d’etablissement” a sales office for sub-contracted watch manufacture. In 1880, the brothers Louis Paul and Cesar Brandt set-up a modern watch production unit. In 1889, the company had a production of 100,000 units per year. The name of Omega only appeared in 1903. Omega has developed amazing movements such as the “Labrador” in 1885. In 1917, Omega provided watches to the British army and in 1918 to the American army. In 1957, the speedmaster professional was born and then selected by the NASA in 1965 as the official timekeeper. Today, Omega continues to demonstrate mechanical innovation and remain one of the most prominent brands in the world of watchmakers.
