Longines. A small and rare stainless steel competition chronometer in wooden protective case

According to the Archives of Montres Longines, the present competition chronometer was manufactured in 1942 and submitted to an observatory contest in the same year, most likely at the Neuchâtel Observatory.

Since its creation in 1832 in Saint-Imier, Switzerland, Longines has played a pioneering role in numerous technological breakthroughs, notably in the world of sports by introducing in 1912 the principle of an electric wire, which at the start and finish of a race, activated and stopped the timing mechanism. The company has also been associated with the history of aviation and navigation. It timed, for instance, Lindbergh's first solo flight across the Atlantic Ocean and, subsequently developed the Hour Angle watch according to a design drawn by Lindbergh himself.
