Founded in 1832, Longines has a rich and exciting history.  The company produced their first movement, the 20A, in 1867 near the Swiss town of Saint-Imier, in a place called Es Longines ("long meadows").  This movement won an award at the Exhibition Universelle in Paris in the same year.  Longines are credited with advancing the industrialisation of Swiss watchmaking and it because of their new mechanical procedures, they were able to produce a simple chronograph movement, the 20H, as early as 1878.  It was the first mechanism that Longines had made that could be used for precise timing and it was so popular with horse racing bettors and spectators that by the end of 1886, Longines were supplying chronographs to the majority of New York's sports officials.  It is still the official timekeeper of many horse races, with over 40 in its annual calendar.

The Longines brand name and logo were officially registered with the United International Bureaux for the Protection of Intellectual Property (later the WIPO) in 1889.  Longines is the oldest brand name registered with the WIPO that is unchanged and still in use today.  Longines is now part of the Swatch Group, having joined in 1983.
