Together with the watch dealers Henri Raiguel and Florian Morel, Auguste Agassiz opened in 1832 a watch sales room and enclosed manufacture. The brand name Longines was registered in 1889 with the State Intellectual Property Office and is thus the oldest registered watch brand in the world. In the 1980s the Swiss watchmaking company Swatch Group joined Longines. At the beginning, Longines produced pocket watches
but from 1903 the first mechanic Ladies pendant watches were created. Shortly thereafter, the first mechanic men’s wrist watches went into production, which prevailed against men’s pocket watches. In 1945 the first wrist watch with automatic winding followed.
Longines also provided timepieces for sporting events and supported the crossing of the Atlantic Ocean by the American aviation pioneer Charles Lindbergh. Lindbergh then advised Longines in the development of a special wrist watch which was able to determine the degree of longitude during a flight. In 1932 this watch was introduced as the Lindbergh model. Longines’ watches produced between 1870 and 1969 are engraved with the production serial number on the back of wrist watches or on the inside the lid of pocket watches. Those numbers tell us exactly, when the watch was produced.
