Compagnie des Montres Longines Francillon S.A., or merely Longines, is a Swiss high-end watch manufacturer based in Saint-Imier, Switzerland. Established by Auguste Agassiz in 1832, the firm has actually been a subsidiary of the Swiss Swatch Team since 1983. Its winged shapely logo design, which was signed up in 1889, is the earliest the same yet still active signed up trademark.
