Founded by Louis Brandt in La Chaux-de-Fonds in 1848, the company formally operated as the La Generale Watch Co. until incorporating the name Omega in 1903, becoming Louis Brandt et Frère - Omega Watch & Co. In 1982, the company officially changed its name to Omega SA, which is currently a subsidiary of the Swiss Swatch Group. Omega SA is now a Swiss luxury watchmaker based in Biel/Bienne, Switzerland.
Britain's Royal Flying Corps chose Omega watches in 1917 as its official timekeepers for its combat units, as did the U.S. Army in 1918. Omega watches were the choice of NASA and the first watch on the Moon in 1969. In addition, Omega has been the official timekeeping device of the Olympic Games since the 1932 Summer Olympics|1932. James Bond has worn it in films since 1995; other famous Omega wearers, past and present, include Buzz Aldrin, George Clooney, John F. Kennedy, Mao Zedong, Elvis Presley and Prince William.
The forerunner of Omega, La Generale Watch Co., was founded at La Chaux-de-Fonds, Switzerland in 1848 by Louis Brandt, who assembled key-wound precision pocket watches from parts supplied by local craftsmen. He sold his watches from Italy to Scandinavia by way of England, his chief market. In 1894, his two sons Louis-Paul and César developed a revolutionary in-house manufacturing and total production control system that allowed component parts to be interchangeable. Watches developed with these techniques were marketed under the Omega brand of La Generale Watch Co. By 1903 the success of the Omega brand led the La Generale Watch Co to spin off the Omega brand as its own company, and the Omega Watch Co was officially founded in 1903.
Louis-Paul and César Brandt both died in 1903, leaving one of Switzerland's largest watch companies — with 240,000 watches produced annually and employing 800 people — in the hands of four young people, the oldest of whom, Paul-Emile Brandt, was not yet 24.
Brandt was the great architect and builder of Omega. His influence would be felt over the next half-century. The economic difficulties brought on by the First World War would lead him to work actively from 1925 toward the union of Omega and Tissot then to their merger in 1930 into the group SSIH, Geneva.
Under Brandt's leadership and Joseph Reiser's from 1955, the SSIH Group continued to grow and multiply, absorbing or creating some fifty companies, including Lanco and Lemania, manufacturer of the most famous Omega chronograph movements. By the 1970s, SSIH had become Switzerland's number one producer of finished watches and number three in the world. Up to this time, the Omega brand outsold Rolex, its main Swiss rival in the luxury watch segment, although Rolex watches sold at a higher price point. Around this time it was viewed as Rolex versus Omega in the competition for the "King of Swiss Watch brands". Omega watches tended to be more revolutionary and more professional focused, while Rolex watches were more ‘evolutionary’ and famous for their mechanical pieces and brand.
