Longines (French pronunciation: [lɔ̃ʒin], lawn-zheen) is a watch company based in Saint-Imier, Switzerland. Founded by Auguste Agassiz in 1832, it is currently owned by the Swatch Group. Its winged hourglass logo is the oldest registered trademark for a watchmaker.

Based in Saint-Imier since 1832, the Compagnie des Montres Longines Francillon S.A. was among the world’s leading watch companies. In 2007, Longines had its 175th anniversary. The brand evolved from a comptoir to a full-fledged manufacturing operation and then back down to an établisseur today, since the early 1980s, as a Swatch Group company.
