Compagnie des Montres Longines Francillon S.A., or simply Longines, is a Swiss deluxe watchmaker based in Saint-Imier, Switzerland. Started by Auguste Agassiz in 1832, the company has actually been a subsidiary of the Swiss Swatch Group since 1983. Its winged hourglass logo, which was signed up in 1889, is the oldest the same yet still energetic registered trademark.
