路Longines timed the first modern Olympics in 1892 and since Oslo in 1952 has been the official Olympics timer 14 times.
Do I need to mention Charles Lindbergh, Amelia Earhart, and the International Aeronautics Federation? Longines did patent the flyback chronograph.
Lots of clocks in the old time baseball parks were made by Longines, including Yankee Stadium. They were the official timer of quite a few US sports teams, including the Los Angeles Lakers.
Horse racing, Formula One racing, Skiing, Tennis, and more than 30 Tour de Frances were all officially timed by Longines.
Just a little counterstick. 馃槈 馃槣
I'll throw in the Rolex clock that officially marked the start and finish of the 24 hrs du Mans (the world's biggest motor race - bar none) for decades.
