Ernest FrancillonIn the early 1800's Swiss watchmaking was truly a cottage-industry. Watches were produced using the 'etablissage' method, where individual tradesman working out of small studios or their homes would produce parts (or sub-assemblies) which were then assembled and sold under the auspices of a single brand. In 1832, Auguste Agassiz began selling etablissage-produced watches under the name 'Agassiz & Compagnie' and was particularly successful selling those watches in North America.In the 1850's, Agassiz passed control of his company to his nephew, Ernest Francillon. Francillon wanted to modernize the production of watches and believed that bringing all the final assembly and finish operations together into one factory would be a more efficient method of production. To accomplish this, Francillon built a factory on a piece of land known as 'Les Longines' and the Longines brand was born.

This method of production proved to be very successful, and by the early 1900's the Longines factory employed over 1000 people and had achieved worldwide distrubution and success with its products. The Longines 'Winged Hourglass' (actually a winged clepsydra for those who care about such things) is the oldest registered trademark for a watch company, having been registered in 1880. The Winged Hourglass logo first appeared on Longines watches in about 1867. Longines - WittnauerThe A. Wittnauer Co.

In 1936, the Wittnauer Co. Was sold by the Wittnauer family and renamed the Longines-Wittnauer Co., a name that became so linked in the minds of the public that most assume that Longines and Wittnauer watches are the same. In fact, they produced distinctly different movements, though both are of similar excellent quality.Longines Chronographs in Sport and AviationLongines was the first company known to have created precision timers for sporting events.
They pioneered the 'broken wire' system, as well as the first 'photo finish' mechanism, which linked precision timing with a photographic record of the event. Longines timers are still used in many sporting events, especially equestrian and gymnastics competitions.
