Longines is a Swiss luxury watchmaker based in Saint-Imier, Switzerland. The company was originally founded by Auguste Agassiz in 1832 and it currently holds the oldest registered logo for a watch  company (a winged hourglass). Longines is currently owned by the Swatch Group.
Longines is known for its 'Aviators' watches. One director of Longines was a friend of Charles Lindbergh; after his transatlantic flight, Lindbergh designed a pilot watch to  help with air navigation. The watch was built to his desired  specifications, and is still produced today.
Famous aviators, explorers and pioneers have consulted Longines. Longines provided timers used at the first  modern day Olympics in 1892. In 1899, Longines went to the North Pole  with Arctic Louis Amèdèe de Savoie. It was the first to use automatic  timekeeping for the Federal Gymnastics, at Basel in 1912. Today, Longines remains a widely recognized name in sport watches and chronographs. (Wikipedia)
